Logic Probe Kit build

And some probulating of Commodore 64 signals

When reading how to diagnose faults on a C64 one finds many mentions of the hallowed tool: 'the Logic Probe.' Being a tight sort of fellow I embarked on quest to procure myself such an eminent device, but at the smallest possible outlay. Behold! A kit Logic probe from the bay of E's...

A new desoldering pump and a C64 NE556 chip change

Lets Play Commodore 64s

In which an electric de-soldering pump makes me jump - and is better than an iron and manual pump used separately. Not perfect - but cheap.

A race off between PCB Suppliers

And a PCB design to connect a servo board to an arduino

As part of my new animatronics experimenting, I decided to design a PCB which I could attach an Arduino nano and a servo driver board, so as to reduce the complexity of the wiring when setting up Nilheim Mechatronics eye mechanism. I needed to provide headers to connect to the servo board, provide some connection to the controller hardware, and make it all neat.

As a bit of fun, I also decided to order the same PCB from two different suppliers, to see who would come up with the goods first..
