Upcoming Projects!

by Ben N on November 15, 2024

No, I haven’t disappeared off the Earth.
Just been very busy. My “day job” in working in media, and I live in Wisconsin. The advertising and political events leading up to the U.S. Presidential Election has been insane! My work has mostly been in live event production lately AT those political events. That means long hours, last-minute requests, and general stress and exhaustion…
Of course, I also got sick right after the election, finally recovering about now.

But in the time since I released my last major YouTube video, I HAVE still been working on a few things – just haven’t had time to edit them.

Some of the major projects include interviewing an Electric DeLorean builder, getting a combination lathe/mill with possible CNC controls, and installing a 2″ towing package on my 2013 Tesla Model S.

Not too long ago, Hoffman EV held an open house at their headquarters in Madison, Wisconsin. I was able to attend and got to chat with Geoffrey Hoffman. You might remember him from a video I shot two years ago about a previous DeLorean he converted. This new one has more range, quicker acceleration, and higher top speed. But no, it still doesn’t have a Flux Capacitor…
I also shot some video on an EV VW Thing and an electric race car built by the local University engineering department!
Look for those as upcoming videos!

I was also able to get a new tool! OK, it’s used, and it’s actually on loan from the Milwaukee Makerspace. But it’s in my garage and gives me the ability to turn or mill metal parts. The Smithy Granite is a combination lathe/mill and it has an aftermarket CNC package added to it.

It was quite the challenge transporting a machine like this back to my garage. Once I got it home, there was still quite a bit of setup, maintenance, and testing to do on it. I have been able to do some basic manual lathe and mill work on it. After reading the entire manual and re-watching quite a few YouTube videos, I cut some threads on brass round stock! Pretty cool to be able to do something like that, as I’d never done it before. I also tried out some basic milling moves on a piece of machinable plastic.

The CNC aspect off all this is a little more complicated. I was able to get the CNC controller to communicate with and power the motors. Unfortunately, there seems to be an issue with the software for the x-axis control. The manufacturer is called FlashCutCNC. They are still around, but this software and hardware is OLD! I contacted their support department and was flat-out told that this is no longer supported and that my only option would be to upgrade all the hardware and software. Essentially just buy a complete new CNC system. Knowing what that cost was, it is NOT an option.
I’ll keep chipping away at the CNC system. It would be an absolute blast if I could get it working right!

Even just under the manual controls, having easy access to a lathe and mill greatly expands what I can do on a project. I hope to be able to make a few parts to finish off some old projects.

I also got a 2″ hitch for the Tesla Model S!
This is a Torklift Stealth. Torklift has been making hitches for eco-friendly cars for some time now. I have had their products on our Chevy Volt PHEV and the Mitsubishi iMiEV.
The 2″ hitch wil let me tow or install a bike rack or carrier tray. Probably the main use though will be pulling a 6×10′ utility trailer. No more having to waste gas to move bulky/heavy objects!

Installing the hitch on the car was actually relatively straight-forward. The hardest part really was removing and reinstalling all the plastic panels under the car.

Although the hitch was easy, the wiring was NOT.
I have a Tekonsha ZCI wiring harness, and as of yet, I don’t have it working right. Previously, I had installed one of these on somebody else’s Model Y, and that install went very well. It turns out that HOW the Model S activates the tail lights vs turn signals vs brake light, it actually makes it REALLY hard to work properly with ANY trailer lighting harness. The car was simply NOT designed for it.

I’ll get the video of the hitch installation posted soon, but may have to wait a while for more info on the wiring!

I also received a new 400V inverter board in the mail. This is a replacement/upgrade for the board I was working with on my Tesla V2L project. I accidentally wrecked the original board while I was trying to customize it. This new board is rated for 8,000 watts! We’ll see how much I can actually get out of it, but in theory, I should be able to do vehicle-to-vehicle charging!

Anyways, I just wanted to give you an update on a few projects that HAVE been going on, even if videos about them are not out yet. Look for some of those videos soon!

Until then, stay charged up!

Vehicle to Load (V2L) Bare Board Experimentation

by Ben N on August 29, 2024

One feature missing from a Tesla sedan is Vehicle-to-Load! V2L means that you can draw Alternating Current (AC) Power from the car to use while camping, in a blackout, or however else you would like to use it. Vehicles like the Ford F150 Lightning and the Hyundai EV6 have this feature.

So, what would it take to ADD this feature to a car which does NOT have it, such as my 2013 Tesla Model S? I’ve been pondering this for a while. In fact, I even had some successful tests of doing the same with my Mitsubishi iMiEV. (See those videos HERE.) Unfortunately, that needed a large external solar inverter and a specially-made CHAdeMO connection.

For the Tesla, I’d love something that could look like it actually came from the manufacturer. When I was troubleshooting the Supercharging feature on the car, I discovered that there was some extra space under the back seat, and it would be fairly easy to connect to the battery pack at the High Voltage Junction Box, (also under the back seat.)

What I would need is an inverter which could take in EV Battery Pack voltage, and output 120VAC, all WITHOUT being a large/heavy/bulky solar inverter. After kicking around a few ideas and trying to find the right thing, I found a particular inverter board on AliExpress. These board are essentially sold as PART of an inverter. A full inverter would need a case, fusing, cooling fans, etc. But the important thing is that I found one that will take in high voltage DC in a range of about 300V-450V, and output 120VAC.

I just got the board in the mail today.
First thing I would need is a source of high-voltage DC. So, I used the same solution as when I was testing a Nissan Leaf Motor – running 240V power to a bridge rectifier. The rectifier converts the 240VAC to about 338VDC. I then connected that to the DC INPUTS on the inverter board.

Making sure not to touch anything (as none of this was inside a protective enclosure,) I tested the output with my multimeter, and saw that the board was producing 220VAC! But I had ordered the 120V version!
Hmm. The next thing to look for was any sort of jumper or potentiometer on the board. I powered it down, waited for the LEDs to go out and test that there was no longer any high-voltage DC present. Then I inspected the board and found a tiny brass adjustment screw. I gave it a few twists counterclockwise, then powered up the board and tested the output again. This time it showed 172VAC. Still not what I was looking for, but I was glad to see the output was adjustable and I was going in the right direction.

After repeating this procedure a few times, I got the output to test at exactly 120VAC.

Next, I connected a low-current 120VAC LED light bulb. Sure enough, it lit up just fine.

So, these tests seem to show that I’m on the right path for an inexpensive piece of equipment which would be appropriate for a DIY V2L setup.

I also took a look at the car for where I might want to connect an exterior outlet. I’d love to be able to re-use the charging port, similar to how the EV6 does, but based on how things are connected internally in the Model S, that might not be an option.

I noticed that on the opposite side of the car, there is a reflector which takes up the matching space as the charge port door. Of course, it’s fixed and just part of the taillight assembly. I removed the taillight and was then able to remove the reflector. With it gone, it looked like there was enough space to install a weather-proof electric outlet. With a little modification, I think I could even 3d print a spring-loaded bracket to hold the reflector to make it open and close. Essentially, I would duplicate the charge port, but on the other side of the car, and this would be for the V2L power outlet.

Well, that’s my idea for now. I also have a 120V-capable Variable Frequency Drive on order. That should make it easy to output 120 OR 240, and have it be easily selectable between the two. That would mean I could even use my car to charge OTHER electric cars!

But you’ll find out more about that when I get it.

Until then, stay charged up!

Low-Tech Off-Grid Shed Lighting

by Ben N on August 14, 2024

For some time now, I’ve thought about adding some basic lighting to my tool-shed. My garage has plenty of power (and even a solar array!) but the shed does NOT have regular 120V power running to it.

I’ve also worked on a few projects making use of Ryobi batteries, both the 18V and 40V versions.

It seemed to me that for as much and as often as I need lighting in my shed, a very simple battery-based system would work well.

I had already created some CAD files for a Ryobi 18V-based emergency backup power light, so I simply repurposed that and made a few modifications to use as a wall-mount battery holder. The main changes were to add tabs for screw holes, and a backer plate to help hold the electric contacts in place.

I printed this out of PLA plastic on my Ender 3 S1 3D printer. I simply set it to go at night, and it was ready the next morning. After removing the supports, I was ready to build the electrical components in the plastic shell.

At the heart of this design is the shape, which holds the battery in place. Where the end of the battery lines up, there are indentations on the 3D print to hold electrical contacts. I used Keystone 209 clips to make the electrical connection. https://amzn.to/46Lh2ci
I soldered a short piece of black wire to one of the clips and the end of an inline automotive fuse holder to the other. https://amzn.to/3M40hj1
The other end of the fuse holder goes to a DC rated switch. 20mm is a common size for switch mounting holes, so I designed the print to allow for popping one of those switches right in place. https://amzn.to/3YKhTYM
Another short wire comes off the output of the switch.
From there a pair of wire nuts connects the negative of the battery and the output of the switch to some lamp cord running to a light bulb holder. I love WAGO lever nuts. They are easy to use and allow for simple addition and removal of wires to a group. https://amzn.to/3YKhTYM
The fused wire goes on the positive side of the 3d print for the battery, and the plain black wire goes on the negative.

In the bulb holder, we are NOT just using any light bulb! To start with, we want an LED bulb, as they are so energy efficient. Another feature not talked about often enough is that they are durable! In a location like a shed, I am likely to accidentally hit a bulb with a shovel or other tool at some point. If you have ever had to clean up a shattered CFL bulb, you know what I’m talking about!

The other thing is that it will NOT be a typical 120VAC light bulb. Nope, we need one that can run on 18VDC. Fortunately, there are already LOTS of bulbs out there designed for 12V systems for automobiles, RVs, and camping trailers. Many of those bulbs will run fine on a Ryobi 18V battery, but the easiest thing to do is simply find a bulb with a WIDE DC INPUT RANGE. These LeMeng brand bulbs work great and will run on anywhere from 10-30VDC! https://amzn.to/4dFwPvp

I screwed the 3D print to the wall of my shed. Two of those screws went through the backer plate to help hold the 209 clips in place. The power switch faces towards the door for easy access. The bulb is mounted above the door, so it’s shining towards what I want to look at.

I inserted the battery into the wall holder and turned on the switch. POOF! LIGHT!
Nice and simple!

Could I have instead purchased a commercially-built Ryobi area light? Yes, I could, but new items get expensive fast, and I really wanted something designed for permanent installation in my shed. Also, the cost of DIY was minimal – just a few dollars in parts.

I also COULD have installed a purchased solar light, or perhaps even figure out how to solar-charge the Ryobi battery. Again, there’s additional cost and complexity. It also assumes the shed is located in a sunny area. Part of this project is to design something which can also be used at my friend’s off-grid property, deep in the woods. Solar really doesn’t work well where his shed is located.

Even a single Ryobi battery has enough power to easily run several lights. These bulbs take no more than 300mA of current. That means that one light will run for OVER 3 hours for every one amp-hour of capacity of a battery. For example, a popular 4AH battery will run a bulb more than 12 hrs.
In my case, I just want to be able to flick on the lights, find a tool or stored item I am looking for, and then turn the lights back off again. So, one charged battery might last 6 months!

I’m a big fan of low-tech and simple. A battery going straight to a bulb is about as simple as a flashlight. But it’s always there in my shed when I need it!

Until next time, stay charged-up!

Bronze Bowl

by Ben N on January 22, 2024

About a month ago, I got a propane forge. It’s designed primarily for blacksmithing, but once I realized that it could get hotter than the melting point of brass and bronze, I had to give METAL CASTING a try!

A few little casts gave me some great experiences fast! I especially like how the Trilobites turned out!
(https://www.youtube.com/watch?v=L4LSYJHodiI)

I’ve made numerous small parts so far, including a trigger guard for a flintlock pistol, a bottle opener, and a bronze spoon!

Since I was building up my skills, I figured that a BOWL might be the next most complicated thing.

My wife has several small orange bowls which she inherited from her mother. They are a great retro orange color. Unfortunately, they are just plain ceramic, and they DO break.

I thought I’d try using one of them as a pattern for a bronze casting. The bowl is a neat shape and even though I can only cast a pretty small amount of metal right now, I SHOULD be able to heat just large enough of a volume to make one.

I’m creating sand-casts. These are simply molds in which a person packs sand around an object to leave an impression in it. The mold is split open, The original pattern removed, the mold is closed up again, and molten metal is poured in the empty space.

For the metal, I’m using 95% salvaged/recycled Copper and 5% elemental Silicon. This is a “Silicon Bronze” and is pretty close to an alloy which bronze sculptors like to use.

I created the sand-mold, melted the bronze, and poured it into the sand-mold. Unfortunately, I didn’t estimate the volume correctly. There just simply wasn’t enough metal to fill it up.

Back to the drawing board….
I made a new sand mold, cut up my failed casting and melted it AND some additional material in the forge. Then I tried casting #2.

This time, the mold filled all the way up, BUT… after examining it I saw that it really wasn’t a great casting. There were numerous odd-shaped voids visible on both the inside and the outside of the bowl. So, this bowl wouldn’t be great for actually eating food out of, but it could still make a great art piece.

I have a 2″ sanding disc that I can put in my cordless drill. I used that and increased the grit of sand-paper starting at 40 grit and working my way up to 2000. I was able able to mount the bowl in my wood lathe. By spinning the bowl AND sanding it with my cordless drill, I was able to get the interior pretty smooth!
I finished it by shining with some Mother’s Chrome Polish.

I wanted to leave the exterior of the bowl rough. I also really like the type of patina created by applying Liver of Sulfur. That’s an oxidizer which will darken brass and bronze. I heated the bowl with a propane torch and then daubbed on the L.O.S. with a shop rag. The bowl turned a dark gray.

In a weird accidental discovery, I realized that I had given the interior of the bowl an amazing rainbow finish! Bronze will change colors depending on how it is heated. By chance, I got this incredible finish. Unfortunately, it was only surface deep, and I found I couldn’t keep the rainbow. I re-polished the inside back to a golden shine.
I’ll have to do some further experiments to be able to take advantage of these tempering colors in the future!

On the exterior of the bowl, I polished it down with #0000 extra-fine steel wool. This removes the oxidation from the higher parts of the surface, creating a bright highlight against the darker low areas. It provides a nice contrast on the rough sand-cast exterior.

Overall, I’m very happy with the bowl!
It even sounds good!
Any why not? Bronze is the traditional metal of bells!


The one big limitation that I have right now is how MUCH metal I can cast. The propane forge is NOT designed to hold crucibles. So, I can only fit a very small one inside.

I hope to soon get a melting furnace! The PROPER piece of equipment for metal will allow me to be able to melt much more at once. This opens the door for larger pieces or to be able to make multiple castings at once!

Needless to day, I’ve been watching a lot of metal casting videos on YouTube lately.
My favorite metal-casting YouTube channels are:
https://www.youtube.com/@lundgrenbronzestudios
and https://www.youtube.com/@robinson-foundry

The Lundgren Bronze Studio videos are especially good, as the host not only shows all the steps, but also his mistakes and everything else in the learning process. Good stuff.

Well, I’ve been having a lot of fun casting metal. Being able to take scrap materials and completely transform them into something else is absolute ALCHEMY!
While I’m not turning lead into gold, scrap copper, tin, and silicon into art is a pretty close second!

Until next time, stay charged up!

Tiny Gold Bar! (Brass Casting)

by Ben N on December 22, 2023

I just made a gold bar! Well, it’s gold colored at least…

I’ve long been interested in both blacksmithing and metal-casting. I recently got a gas blacksmithing forge. This 3-burner is great for general heating of iron bar stock for blacksmithing.
https://amzn.to/3RU4GsA
Just turn on the gas, light it, wait a few minutes, and you have a nice heat for general work.

However, when I looked at the specs on it, they said that it should get hot enough to melt brass. I got curious, so I mail-ordered a crucible (a high-temperature pot for melting metal.) Since the forge is not the right style for melting metal, I only purchased a very small crucible, to make sure it would fit inside.
The #0 size looks like it’s about a shot glass and will hold one pound maximum of molten metal.
https://amzn.to/3vbjpGv

After an experiment or two, I found that it was fairly straight-forward to melt scrap brass. Much of the brass I used was spent .22 rounds. I first tried making some castings just by pressing objects directly into some generic sand, but then I wanted to see if I could make a real shape from scratch using 3D modeling.

Since the brass has such a nice shiny yellow color, I imagined a stereo-typical gold bar. I set to work modeling one in Fusion 360. I’ve been slowly teaching myself this software. While it is total overkill for this simple project, it does have some other features I found useful. For example, it can calculate the volume of any object I design. By assigning a material, such as brass, it pulls in density information and automatically calculates mass. In that way, I could make sure to design my shape so that it fits within the amount of metal I can melt in my tiny crucible.

I drew out the gold bar in CAD.
One reason why I wanted to make this shape is that it already has a draft. Draft is simply having an angled edge in a pattern so that an object can easily slip out of the mold. That’s why the sides of a gold bar are slanted!
A 10 degree angle on the sides of the bar looked about right.
I also embossed the lettering “24K” into the face of the bar, and made sure that had a draft as well.
Lastly, I changed the height of the bar until the calculated weight would match what I knew I could melt. The software calculated a little over 7 oz, or around 200 grams.

With my 3D object complete, I exported it to my Ender 3 S1 3D Printer.
https://amzn.to/3tsDI1C
I printed the object out of plain white PLA plastic.

Next, I heated a screw to thread into the back of the print. This would give me a handle to pull it out of the sand mold. I removed the screw and set the print in the bottom of an open wood box, which would hold some sand.

My “green sand” is a mix of fine grain sand and about 10% powdered clay kitty-litter with enough water added so that it clumps hard when squeezed in a fist. This type of sand can be packed down and becomes quite firm.

With the 3D print in place, I covered it and the bottom of the open box with chalk dust. I hoped that would work well as a release agent, keeping the sand from sticking. I loosely sprinkled sand over the 3D print until it was completely covered, and then packed it down. I then kept adding and packing sand until the frame was filled solid with it.

Next, I flipped the frame over.
Before pulling out the print, I decided to cut a small trough in the sand with a piece of pipe. I thought it might be best to not pour directly into the mold, as the weight of the molten brass might push too hard against the fine sand of the embossed lettering, ruining it. By pouring to the side of the bar and then letting the molten metal run in, I was hoping it would increase my chances of having a good casting.

I threaded the screw into the back of the 3D print, gently tapped it a few times to try to release the print from the sand, and then gently pulled it out.

This left me with an indentation in the sand the size and shape of my 3D print. However, I also noticed a small amount of sand that came out stuck to the face of the print. This would cause a rough surface, but I saw that the lettering itself still looked pretty good.

After that, it was time to melt down some brass, heat the forge, add scrap brass and a little Borax as flux, and get ready for the pour.

I poured the metal into the sand and let it come up to even with the surface. In fact, just a little further. Although I had leveled the sand-mold as best I could, it was still just a little off, producing a bit of a slant on the open top side of the casting.

Grabbing the casting with some pliers and throwing it into a bucket of water, I was very pleased with the initial result. It was the right size and shape and the lettering was clear.

At this point, I realized that I should have made the runner to the casting MUCH smaller. The pouring area had become a large hunk of metal with a LOT of surface area connecting it to the gold bar. This required a lot of cutting. I put the casting in a vice and cut off the extra with a metal-cutting blade in my cordless reciprocating saw.
After that, it was a bit of grinding to clean up the cut marks.

Next was sanding. I used a series of rough to fine sand-papers on a disc sander to take off the rough surface, smooth it down, and shine it up.

I also wanted to darken the lettering. I thought I would try ammonia vapor to do that. By simply placing a brass object in a jar above a small amount of ammonia, the vapors will react with the surface to oxidize it and make it dark. About an hour later, my gold bar was completely dark gray.

I polished the oxidation back off, but unfortunately by the time I really had the top of the polished bright, the #0000 steel wool had also polished away most of the darkness in the lettering! Worse than that, the oxidation also really showed off the scratches on the side of the bar where I put in significantly less time sanding and polishing! Oh well…

In the end, I had a nice little hunk of brass which looked like a gold bar. The drafting made it pull fairly clean from the sand mold, although I still need to improve my sand and release agent. With the exception of the bottom-left of the “K”, the text came through very well. I later painted it in with a little bit of black hobby paint, and it looked very nice.
Final weight was right around 7 oz, just as the CAD software said.

It’s VERY cool to be able to have an idea, create it in 3D computer space, and then make it into a real, tangible, and HEFTY item. While the gold bar is nothing more than a shiny paper-weight, it was GREAT practice in making and learning how to improve my next cast.

I’m hoping to be able to get a proper casting furnace which will be able to handle good-sized crucibles for making larger castings. I also need to start working on two-part molds so that I can create a casting with details on all sides, rather than a flat top only!

Casting is a blast, and I’m sure you’ll see more from me in the future!
Until then, stay charged up!

Converting this International Harvester 300 Utility tractor to electric has had a few challenges.
