I didn't choose the MCU ... it chose me!
Log from TI-57 Programmable Calculator Hardware Retrofit
I like the STM32 ARM cortex MCU family. They are well documented, readily available, and cheap 'breakout boards' for them abound. The MCU retrofit must fit nicely in the space of a 28-pin 0.6" pitch DIP, so package size is key. The STM32F103 is...

Power Supply and Lid
Log from TI-57 Programmable Calculator Hardware Retrofit
Rcl57mcu wants a 3.5-5V supply. So, even if I could resurrect the dead BP-7 NiCd pack/lid, it won’t work for this upgrade. I will instead recycle the tried-and-true USB charged 3.7V LiPo supply that I’ve used for HP Classic, HP-28S, and TI-58/59 supply...

Small challenges to my robot
Log from Balancing Robot based on STM32
Finally, I assembled the robot and did the first tests. Considering its size and DC motors with huge backlash, the robot does a great job keeping the balance.

Day 1: Arriving (late), Selecting a Concept, and Forming the SuperDuo!
Log from Cultural Integrity (at the Dethrone Hackathon)
Everyone respected my hacker alias and called me 'crip' when I arrived...even got a nametag: "Crip Lishus" - hellyeah! (Given names are so boring and prescribed. It's nice to reinvent ourselves and our identity to match what we like and...

Does controlling OSPi with the other GPIOs work?
Log from MQTT hack for OpenSprinkler OSPi
Yes. Again a small program (sensor-test.py) and corresponding programming of OpenSprinkler shows: it works! (From now on, as I directly connected the GPIOs, I did not use any pull-ups anymore.)

Initial Design
Log from BWLC1A: Yet Another ESP32 Asset Tracker
Initially, I roughly design the device to meet the following points: Slim and smallCellular connectivityGNSS -based location trackingLow-costBattery-powered and Rechargeable Working on the schematics, I was able to achieves those points and choses...

Ego satisfaction... again (not built yet)
Log from ML Clip Cam
So this project is much simpler than the previous ML Hat Cam where it was this massive thing with steppers. The zoomable voice command feature was really neat and it had a control loop to autofocus using laplace variance.(Nickelback: look at this piece...

I must fly...
Log from ML Clip Cam
In 5 daysThis is a distraction from writing the Pelicam software but days off and nice weather, have to flyI'm going to at the very least build a crude 1 day thing that functionsIt is pretty much just a battery-powered rpi cam... but it will be attached...

Week 1 & 2 - PCB Layouts
Log from 25in24 Electronics Project Board
I've started by laying out the five boards in Eagle 9.52. Boards are now being ordered through JLC. All parts have been ordered through Mouser and Digikey - however sourcing a small meter and solar panel that will match have been a bit of...

From prototype to product creation
Log from VGA videocard for microcontrollers
First of all, you should pay attention to the ROM used. The flash-ROM chip from an old computer motherboard has a finicky parallel interface where the address is written in two runs. This complicates the operating logic and increases access time. Additionally,...

What is an egg?
Log from Wobble
Starting project by learning more about eggs.. I'd like to figure out how to create a nice 3D printed egg shape that can hold a circuit board, battery, and motor assembly. I'll start by printing off some free variants from thingiverse. Ultimately I want...

Development boards and wobbling madness!
Log from Wobble
I started writing some programs to control the DRV8825 using a few small embedded boards I had lying around - the Metro by Adafruit and Arduino Uno both of which are based on the ATMEGA328P processor. I went with these because I wanted something...

1080 LEDs in the Palm of Your Hand!
Log from MiniSphere
We're starting to finalize some of the bigger pieces of this project, so we're excited to start sharing our progress! We've got the geometry and LED arrangement set, now we're testing our electrical design and getting started on writing some animations....
