Re: Metal Casting Group - looking for interested folks

We can get green sand from several of the foundries around town. I don't have a crucible, and I'd like to get a better working burner than the one I have. I think Steve's foundry, though huge, has a crucible. Maybe I can whack one together out of some steel pipe and a bit of plate. My foundry is onl...

Re: What would you like to learn in a leatherworking class?

I would love to learn how to make leather armor. I know I need to learn the basics first, but learning how to make a leather curaiss/tunique would be cool.

Re: Zeolite / Water solar refrigeration system

I got my 100 lbs. of zeolite the other day. It's much finer than I thought it would be, though the package says it's zeosand, a pool filter replacement thing. Still, the bits tend to fall through the small window screen mesh I'm using, so I need to come up with a better solution. Also, it probably n...

Zeolite / Water solar refrigeration system

Was looking into biogas generation, and I think I got a good handle on that, but during my research into that I came across some articles about Solar Refrigeration. The upshot is that using an adsorbant material, like carbon or zeolite, and the application of heat you can create a cycle for cooling ...

Android / IOS, NFC, BT, Miracast mobile wireless workstation

Another idea that has entered into my brain that I need help with (the idea, not the brain); I would like to be able to take my smartphone and once it entered into the proximity of an NFC device would fire up an app that would simultaneously do a WiFi pair with a Miracast device plugged into a monit...

Re: Electrolysis Rust Removal

I was able to do some testing yesterday, the results are promising. I started with 5V and measured the amps at about 4.5 - 6.5A. It took about 6-7 hours and looks like it could use another 1-2 hours. I then tried a similar part at 24V and immediately blew the 1.5A fuse I had on the AC plug in. I dec...

Re: Electrolysis Rust Removal

Got the box knocked together. I simplified the design by not having a switch to go from the higher voltage to the lower, instead I'm just using an outlet with the two plugs going to the different rectifiers. The two transformers work exactly as I expected and the voltage drop across the rectifier br...

Electrolysis Rust Removal

One of my other projects is taking the subframes and running gear from a miata and putting a tube frame chassis on it. It's a kit car called an MEV Exocet. In removing the subframes and other pieces I came across a lot of rusty bits. I hate spending hours wire wheeling, sanding, applying POR15 rust ...

Re: Portable Recheargable Tunes v2.1

Update: I breadboarded the circuit but it was very quiet and I needed full volume in order to get the slightest bit of noise from the drivers. I'm not sure if thats due to some bad connections on the breadboard or what, but I'm looking at modifying my pcb in order to add a couple resistors, or a pot...

Re: Portable Recheargable Tunes v2.1

Super teeny tiny soldering job is done! I soldered SM components once and I was terrible at it, it worked, but it wasn't pretty. This time I managed to solder not one, but two SOIC chips with a pin pitch of .05" to a DIP conversion board. I did get a solder bridge, but Steven was kind enough to...
