CNC Wood Router

IMAG2942The Pen-Plotter Turned Wood Router from an old dell printer, this time cutting a sign for my workshop, and some wooden gears!


Dell Printer V515w CNC plotter

Filed under: CNC — dynamodan @ 1:45 am



Here is the first iteration of my CNC machine, a pen plotter made from an old  dell printer, which eventually turned into a CNC router.  This machine uses the original motors and sensors for X and Y axis, and eventually an RC servo for the Z.  The shot here is lacking the Z axis at the time I took the picture.


Inline Skate Pillow Blocks

Here’s how I made the pillow block bearings for my CNC machine.  This is very inexpensive, convenient, and sturdy. (more…)

Charcoal Powered Chevy Lumina APV

Filed under: Alternative Energy — dynamodan @ 5:30 pm October 10, 2014


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

Filed under: Alternative Energy — dynamodan @ 3:55 pm June 10, 2013


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

Filed under: Electricity and Electronics,Made Machines,Welding & Metalwork — dynamodan @ 1:26 pm June 5, 2013

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

Filed under: Electricity and Electronics — dynamodan @ 12:35 pm


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

Filed under: Alternative Energy,Welding & Metalwork — dynamodan @ 12:59 am August 12, 2012

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