The ccTalk Interface Circuit
Log from Un-Inhibiting my Microcoin QL
Bottom Line Up Front CCTalk uses a single data-line to transmit and receive data. An interface circuit is needed before connecting with your PC’s serial port. Let’s talk about alternatives, the actual circuit and then breadboard one. TL;DR Directly...

Reading of 6502/65816 CPU Registers by a PC-based Debugger
Log from X65-SBC
Modern microcontrollers and microprocessors have built-in facilities for external debuggers to read/write registers, set breakpoints and generally fully control the CPU. This is one of the main usecases of the standard JTAG interface. The 6502 and 65816...

TOTP Authenticator
Log from Hardware 2FA TOTP authenticator
After I decided what screen to use I made a PCB that has a USB port and a place to connect the screen. Test with the ST7735 display on the PCB (not the 135x240 ST7789)Testing the USB HID Keyboard functionality

More buttons / rechargeable RTC battery / simplified PCB / Case
Log from Hardware 2FA TOTP authenticator
When I designed the first PCB, I didn't really consider the ease with which they could be assembled. This was quite annoying as I would have to hand solder one side (as I could not reflow the other side). This and the idea that I wanted a rechargeable...

Not quite modular yet... sunk cost?
Log from Modular Pi Cam
Oh man... so I've been trying the wide angle camera and I'm just disappointed honestly... I guess what do I expect you know? You can't compare this to a real camera eg. Sony Alpha Nex-5n (APS-C camera from 14 yrs ago). I went ahead and ordered the standard...

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...

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...

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...

PSU #084, an EX1810R
Log from Thurlby Thandar PSU repair
This is a switch-mode PSU, so the mains is rectified to around 400 volts DC inside. Extra care is required to avoid touching this dangerous part of the PCB. Fault: Sparking at back of unit. Suspected cause: Faulty power connector or EMC capacitors. Examination:...

PSU #095, a CPX400SP
Log from Thurlby Thandar PSU repair
This is a switch-mode PSU, so the mains is rectified to around 400 volts DC inside. Extra care is required to avoid touching this dangerous part of the PCB. This can be remote controlled by GPIB, RS232, USB or Ethernet. The user manual is here: CPX400S+SA+SP_Instruction_Manual-Iss9.pdf...

PSU #099, an EX354RD
Log from Thurlby Thandar PSU repair
This is a switch-mode PSU, so the mains is rectified to around 400 volts DC inside. Extra care is required to avoid touching this dangerous part of the PCB.Instruction manual:EX354RD+EX354RT_Instruction_Manual-Iss6.pdf Fault: Not marked on unit. Suspected...

Balancing Robot PCB Update
Log from Balancing Robot based on STM32
Just received the new version of the balancing robot PCB with key improvements – correct connector orientation and streamlined design by removing unnecessary parts. Stay tuned for more updates!

IVEE
Log from Calculators
IVEE, a FORTH-based Arduino calculator is a mostly completed project. It is based on IVEE by zooxo. Kudos to zooxo for designing this beauty and making it public. Please visit his repository, give it a star and watch his video explaining the features...

EXTRA UPDATE - DANGEROUS?
Log from NOOBIX IOT
READ THIS:● Some of you guys on the community commented that the AC high voltage clearance is too low. YES, YOU ARE RIGHT! I usuall add copper plane to all my PCBs and that was a mistake made ina hurry. So even if you see a bad clearance in the...

Project Log 1: Project Start
Log from Magneto-Flex
I got this idea based off of a research paper a friend showed me and decided to go full prototyping mode with it!So let's say we have two tapes right, E is our tape with magnets on it, which is slightly longer than D (which has hall sensors). They are...
