ximite computer. 

The Maximite is a small and versatile computer running a full featured BASIC interpreter with 128K of working memory.

It will work with a standard VGA monitor and PC compatible keyboard and because the Maximite has its own built in SD memory card and BASIC language you need nothing more to start writing and running BASIC programs.

The Maximite also has also 20 input/output lines which can be independently configured as analog inputs, digital inputs or digital outputs. You can measure voltage, frequencies, detect switch closure, etc and respond by turning on lights, closing relays, etc

Two models will be shown, one full-wave rectified and the other a half-wave rectified negative ion ionizer. Featuring an optional fan on the full-wave model.


CAUTION
  • HIGH VOLTAGESpresent in both devices is high enough to induce a bad case of temporary Tourettes. ie twitching/profanity.
  • Be aware of the hazards when working with loose CARBON FIBRE filaments if using this option for high voltage grid instead of pins.

Homemade Bike Stand for Bicycle Repair

imageOverview

This bike stand has been made for easily repairing bicycles using simple design.

Explanation

One of the materials used is the clamp which is made by welding angle iron to the bar stock and then welding the bar stock to the pony clamp jaws. The angle iron is flattened using the vice and solidly weld to the bar stock. The bar stock is weld to the clamp using Nickle 99 cast iron welding rods since the clamp might be difficult to weld to because it is made of cast iron. For the clamp not to mark the paint job when putting the bike, some heavy padding is glued using epoxy.

The T-piece is made by nothing the long 1” pipe in order to be welded to the short 1 ¼” pipe. This is also the same when making the base where two hex nuts where welded into the drilled holes. Welded to the end of the square stock is the bar stock. During the assembly, the long piece of 1 ¼” is screwed into the base while the T-piece is slid into the base. The height is adjusted with eyebolt.

Rest of the project

Back in 2000 I wrote an article for Nuts&Volts magazine about predicting earthquakes via a electromagnetic monitor. Back then the EM sensor rotated through 180 degrees taking readings as it went. That was because EM sensors were expensive. Today they are cheap and I am working on a new device that uses 8 sensors in a circle. I am not sure If I should read them or take their difference and read that?
