If i get the chance il send you a pic from a wah pedal i made from scratch for my guitar
using some parts from our beloved MFP's.
My father would love to join these kind of discussions

Would be great to see that pedal. Into a bit of guitar myself.

Someone else posted a "Man's Lamp" picture.

This is a Lamp that my grandfather built (1 of 7) after his time working for the Utilities Department in our home town. Everything internally still spins and does it's thing.

Wow that is so cool. Nice thing about lamps are you can make them esthetic and they are always practical.
And its now a heirloom for the next generations.

Here is a STK-driver from a copier in action, in preparation for my all copier part CNC scriber/plotter/router.

Wow here again making PCB with the scribing route. Still blows my mind!

Re Electronics Design Software.
Would luv to get hold of an updated 1995-8 version of "Electronic Workbench" software.

Was very good software for the 8086 CPU era....

There was a cute little app called "Crocodile Clips" that i used for simple circuits. Would be awesome to find a working copy.

Finally finisher the Ozone generator prototype thing.
Still need to do the Arduino stuff for PWM control and a timer.
It works great, better than I imagined.

Made from mostly scrap!
Includes:
Flyback transformer from a broken PC CRT.
Scanner lamp driver from a C360.
Toner pump from a B1250.
Fans from a xerox know knows what.
A 24volt supply.
PC PSU wiring and switch.

The cracker tube is made from a piece of 36mm 304 stainless pipe off cut and a TIG electrode.
3D printed the other bits.

Run of an oxygen bottle for medical stuff like ozonated water or low level exposure.
Got the "air pump" for disinfecting rooms and getting rid of bad odors.
The cigarette smell was removed from my car in 2 hours!!
