ETTL protocol with the EOS RP & 580 EX II
Log from Wireless ETTL flash conversion
The STM32 board was just a hair bigger than the PIC, but the biggest pieces are still the power switch, channel button, & battery. The plan is just to print an L enclosure which scotch tapes around the hot shoe & sticks up. The antenna will...

We’ll be on Maker Faire Kyiv this weekend!
Log from uECG - small open source wireless ECG sensor
Quite symbolically, this Saturday, on March 2, Kyiv will host the first Maker Faire Kyiv in a long time! The last one was in 2018.Where, in addition to uECG and uMyo, we’ll present our first project in collaboration with TURFPTAx The device working...

We’ll be on Maker Faire Kyiv this weekend!
Log from uMyo - wearable EMG sensor with wet/dry electrodes
Quite symbolically, this Saturday, on March 2, Kyiv will host the first Maker Faire Kyiv in a long time! The last one was in 2018. Where, in addition to uECG and uMyo, we’ll present our first project in collaboration with TURFPTAx The device working...

Interfacing ternary and binary components
Log from Homebrew ternary computer
Ok, now it is kind of proven that binary CPLD (or FPGA) may implement ternary logic, but how we can integrate it with "true" ternary components, especially when CPLD is 3.3V and TRIMUXes are -5V and +5V? Answer is DG403 chips may do the job: Because...

The actual informations
Log from Extension card for TDS3000 scopes
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....

Terminal-BASIC programmable calculator
Details from Terminal-BASIC programmable calculator
This project is inspired by the nostalgia for portable devices like USSR "Электроника МК-90" and Texas instruments TI-92. END USER REQUIREMENTS (An Ultimate Hacking Machine):o Retro look and feel. PWR,...

Bug fix: the "ghost RTC"
Log from A 4$, 4ICs, Z80 homemade computer on breadboard
Reading this Japanese article on a kit sold in Japan to build a Z80-MCB, I realized the presence of a possible bug seeing this two images: As you can see, there is a Z80-MCB without any Virtual Disk or RTC attached and in the resulting screenshot the...

Self Optimising Automated Arduino Nutrient Doser
Log from Hacking the way to growing food
This Blog is about making a nutrient dosing system for hydroponics that is plug and play, I didnt quite get it to the full stage of plug and play with this version. But it is almost there. Because the change of nutrient strength of our systems can be...

Terminal-BASIC programmable calculator
Log from Terminal-BASIC
I think about Terminal-BASIC based programmable calculator, like MK-90 I am planning to use Arduino DUE, TFT screen schield and custom matrix keyboard of40-64 keys.Does anybody know, if this shield is compatible with arduino DUE?Actually, I'v just tried...

Debugging
Log from 8 Bit TTA Interpreter
Debugging Need to get this project working. One problem is that the Nano does not have enough pins. So I have used a Meduino (a Mega2560 Pro Mini). Here is the schematic: Here is the PCB: The ports (P1 & P2) match the TTA8 bus. A problem with the Meduino...

In The Digital Domain
Log from Reverse-Engineering the milight on-air protocol
I also wanted to sniff the communication between the micro controller and radio IC, but couldn't get the case of the remote control open. At the next opportunity I brought the Mi-Light Wi-Fi controller with me and got that open more or less easily:Inside...

All Your ISA Belong to Me!
Log from DDL4-CPU
Before I began the layout of the DDL4-CPU, I came up with an initial Instruction Set Architecture (ISA) for the design. It went through several revisions as I was designing the boards and refined the components. Here at the last minute as I am...

Micro-coded controller deep-dive
Log from Custom circuit testing using Intel HEX files
In this project, instead of using a standard embedded processor and programming it to execute 3 tasks at hand (parsing HEX character stream, generating HEX character stream, and writing character stream to video RAM driving VGA), I created 3 independent...

We get signal
Log from Reverse-Engineering a low-cost USB CO₂ monitor
Indeed, immediately after running the Windows software in a VM with the device connected I was getting a live data log of the CO₂ concentration! This screenshot shows me breathing into the vicinity of the sensor:Ok, time to disconnect the device from...
