Charcoal Powered Chevy Lumina APV

Here are pics of my 1991 Chevy Lumina APV minivan which I added on a charcoal gasifier.  This has a 3.1L V6, with throttle body fuel injection.  It still runs on gasoline too!

I stenciled a brief description “CHARCOAL POWERED” on this blue-barrel-thingy so people know what it is.  I also coated the scorched spot with high-temp stove paint to help prevent rusting.  Eventually, I may paint the whole barrel black, or maybe just the lower 2/3rds of it, where the heat is.   There actually isn’t much heat when it’s operating correctly. The paint scorched when I was on a long drive, when still using a top-down air intake.  The present design uses a firebrick hearth, and the barrel doesn’t get as hot now.

Charcoal Powered Lawn Tractor

Here are pics of my Bolens Husky 1256 which assembled in 2013 and ran for some time on charcoal.

This shows the tractor with the gasifier mounted, and the rototiller attachment.  I was careful to engineer the mounting so that the tiller would still mount up and operate.  It worked fairly well but there was some lack of power so it just went slower.  I also ran it with the snowthrower attachment which worked well also.  I later added an EGR (exhaust gas recirculation) pipe which enabled the gasifier to run cooler and use charcoal more efficiently.

Wire feed spool gun

After a number of years since my last attempt at making a wire-feed welder, I had spare parts lying around and decided to take another shot at it.  It’s made from a cordless drill motor, bits of brass tubing, jumper cables and such.  The nozzle is a Hobart ceramic for flux core wire, and the contact tip is ordinary tweco-compatible (US-Forge brand if I may be exact).  It works surprisingly well connected to my homemade AC welder.

Thermoelectric Wood Cookstove BioHeavy

Filed under: Alternative Energy,Electricity and Electronics,Hiking N Camping — dynamodan @ 1:22 pm April 13, 2013

This wood-burning, electricity generating wood cookstove is inspired by the BioLite.  But it isn’t lite or light.  So I call it the BioHeavy.  It utilizes three thermoelectric generator modules, two of them borrowed from this project.  Also I modded a 12v computer fan to run on as low as 3 volts, so that the fan draft will still operate the stove at low starting temperatures.

Organizing methods

Filed under: Electricity and Electronics — dynamodan @ 1:49 pm January 30, 2013

Here is a few ways that I organize my growing collections of junque.  Pictured above is a wooden rack I build to accomodate Avery “Crack-n-peel Plus” label boxes that I collected while employed at American Speedy Printing back in the 90′s.  The boxes are approximately 8 1/2″ x 11″ x 2″, to hold a standard letter-sized ream of label stock.  This is in response to an “Ask Hackaday” post.

Soldering iron controller

This is my cheap soldering iron controller for the benefit of hackaday readers in response to this post.

It is simply a cheap lamp dimmer, wire nutted to the cord about 8″ back from the plug.  It works very well.  It was borne out of a need to solder thin paper phenolic boards without causing them to delaminate.  The iron is only 30 watts, well below the dimmer’s rated 600 watt maximum.

Wood-fired water heater

This is the details of my wood-fired water heater, converted from a natural gas water heater.  Sounds dangerous doesn’t it?

Wheelbarrow Concrete Mixer

Filed under: Made Machines — dynamodan @ 12:25 pm May 19, 2012

Here is a wheelbarrow concrete mixer I made as my spring of 2012 project.  All except for the drive belt and minimal hardware, the materials were “recyclables.”  The tumbler is made from an old poly pickle barrel. (more…)

HTC Incredible 2 tripod mount bracket

Filed under: Electricity and Electronics,Welding & Metalwork — dynamodan @ 4:01 pm March 16, 2012

I’ve been thoroughly enjoying my new HTC Droid Incredible 2 smartphone, but one thing I’ve been wanting is a way to secure it on a tripod.  Well this morning I got one made.  I made it out of cheap heavy guage stove pipe steel.  (I think it’s 16 guage.)

Benchtop power supply

ATX Computer power supply as benchtop power supply. These are quite common around the net, but this is mine with my favorite twist.
