Think about it :-)

Inspite of all of the fancy lights and decorations festooning a modern clothes iron - the main control is based on a very old design from the past the Bimetallic Strip switch

Crimped Connector

The contact faces of a small relay - showing the effects of high current switching- causing pitting and face degredation.

A little project for coupling piezo sensors to a data recording device for monitoring low freqeuency vibration levels.

A bit of a lash up but it works :-)

All ready to go in it's little screened box.

My entry for a photo contest at my university a few years ago. Everything is thought in this montage, from the "1337" displayed by the nixie tubes up to the font I used here (Avant-garde), the location of the fake radium sample and the placement of the components.

I didn't score at all. Tasteless people with no culture.

Abstract

A flat little rock perfect for a 2 ½ x 3 ½ ATC.

I used gizmos, ball chain, tempered glass and a rock.

I use this for testing Stepper Motors that I've salvaged from various sources and for checking that motors are OK

It uses an Arduino Nano and an easily available Stepper Driver
