Something to share
One might think, and experienced hardware creators would know one would be wrong, that when the PCBs come in you can populate them and everything will work just fine.
The PCBs I ordered were exactly what I had requested but …
“Buttoning” up the prototype
UPDATE: There are some major errors in all 3 PCB designs that were found after testing so I would not use them. I removed the links to help remove temptation.
After getting the potentiometers to work as expected I was …
So many broken things but now fixed.
It has been quite a while since the last post and the reason is that I just could not get two chips working on the same SPI bus until now. I had the basics right but a few different things …
And the numbers go up and down, or testing a voltage divider.
One of the steps of building the hardware and software solution is to learn how to drive the IC you want to use from an Arduino. The first piece I worked on was the MCP41010 digital potentiometer.

Porting Eamon Adventures – First challenges, characters.

Porting Eamon Adventures to .Net
In my youth I had some spare money to spend and a public domain software catalog for the Apple II and so I bought a few software titles. Among those titles was the Eamon Adventures Master and a handful of …
