In the latest news on the BeefyDuino frontier, my friend Ryan who is the founder of elequa, the company I am helping to start, assembled eight BeefyDuino prototypes (with a little help from his friends including me). He did this because he was going...

muahaha, I cheated :)
Log from Game Boy Cartridge plus Programmer
So since the Teensy++ 2.0 bootloader is not available and I'm not feeling comfortable to learn all the bells and whistles of USB communications I was looking for other options. Googling "at90usb1287 arduino" I found this https://github.com/mattairtech/ArduinoCore-avr...

Digital Pot Shots
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
As you can see below, I am breadboarding the new peak detector changes before committing to a new PC board. One of the changes involves using a MAX5387 digital potentiometer to control the square wave amplitude and EC amplifier gain. The...

Rebalance Progress
Log from Raspberry Pi Ceph Cluster
The rebalance is still progressing. It's particularly slower because I also changed the failure domain on my cephfs EC pool from OSD to HOST which increased the number of PGs that needed to be remapped. Aside from that, the rate of progression...

September 28th 2023: I can't make the linear actuator move precisely
Log from Automatic Moving Cricket Wicket
It was dumb to use a DC motor for this project. I should have just ponied up the resources for a high speed stepper. My plan was to attach a rotary encoder to the DC motor to accurately measure the number of rotations. This is not easy....First, I tried...
