The first one!
Log from Anwaar Amulet - The story so far
Project Log #1 Little sparks for a gift - sometime in 2019 I think. When I moved to colorado about 5 years ago I got a job in PCBA assembly. It sparked a lot of on and off the job learning about circuit boards and their manufacture. In another lifetime...

Decision on the Sensors
Log from Automated Rabbit Hutch Door
As mentioned in the last log, Thermopile matrix sensors sound like a very promising idea so did a short search wich ones would be available (see table below). But the would require at least some kind of image recognition which makes them complex to use....

Pulse counting (part 2)
Log from Battery powered LED pulse counter
After testing if the ESP32-C3 could wake from a rising edge GPIO, it does not seem to work. The datasheet was a bit ambiguous, but after writing the RTC_CNTL_GPIO_WAKEUP_REG for edge trigger the MCU would not wake when a signal was applied to the GPIO...

PCB Bringup
Log from Battery powered LED pulse counter
I received the PCBs from JLCPCB which look great, however I have found some issues with the board: The TPS61023 boost converter IC I selected will operate down to 0.5V input, but I managed to overlook the point where it states that it requires 1.8V...

Laser marking test
Log from Claymore - SLS 3D printer using polymer clay
Kinematic systemRecently (early March 2024), I built the kinematic system to move the laser head and the print bed.The laser moves in X (left-right) axis, and the bed moves in Y (forward-backward) and Z (up-down) axis.All the axes are driven by cheap...

Blue Pill Emulation
Log from TI-57 Programmable Calculator Hardware Retrofit
Another key part of ensuring that replacing the TI-57's TMC1500 "brain" is possible is to ensure that the MCU has enough throughput to emulate it. My initial assumption was that a 64MHz 32-bit ARM MCU should be more than up to the task of emulating a...

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...

Research 2
Log from Micro Pong
Made a list of the most common communication interfaces used found in job descriptions for Electrical/Hardware positionsGoing to use PCI/e, HDMI and USB for sure, may also use SPI or I2C, we will seeCurrent interconnect plan:Not sure if I will SPI, I2C...

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...

Day 1 (Part 2): Night Owl
Log from Cultural Integrity (at the Dethrone Hackathon)
Now that we were getting out of the concept realm and into the real world tangible stuff, my anxieties began to relieve a bit. It was time to take some measurements ! I rolled over to the nearest bus stop, and took out my midnight measuring tape...

Day 2 (part 1) - Fabric, Access, Workshop and LEDs!
Log from Cultural Integrity (at the Dethrone Hackathon)
The big hacker day was upon us and the gears were in motion! Julia jumped into action during morning solo hacker time. She went to the Mission Fabric Outlet store to find our throne-worthy textiles, as well as coordinating with a participant...

Day 2 (part 2) Rap Music & "Shopping"
Log from Cultural Integrity (at the Dethrone Hackathon)
Julia and I rushed over to TAP plastics, hoping to get our acrylic sheet before closing. On the car ride over, I opened my CD case and asked Julia, "is there any music thatyou'd like to hear?" "You just have old people music, right?'" she said. She wasn't...

Day 2 (part 3): Spray Cans, Ultrasonics, and Mischief
Log from Cultural Integrity (at the Dethrone Hackathon)
Once we got back to my apartment, the fatigue began to set in. It had been a long day already, with nonstop running around. I asked Julia if she could wait for a few minutes while I rested. She was totally understanding and didn't give me...

Serial port
Log from TTi 1705 True RMS multimeter teardown
The serial port pin-out is cunning designed so that you can connect to a PC with a simple modem cable, or daisy-chained with other TTi devices. 1 Power to optional PC-02 2 TXD Transmitted data from instrument to PC 3 RXD Received data to instrument from...

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...
