Backplane
Log from Old school IC tester
I decided that interface between ZIF-socket and host machine will be implemented with help of this antique ISA backplane manufactured in 1984 (I bought it for about $20 last month):I cut out it a little to remove part with pull-up resistors, because...

Electronics Overview
Log from High Power Experimental Rocket Platform
I've done a fair amount of work on the electronics side of the project. I've integrated the sensors, microcontroller, transceiver, and completed the remote ignition circuitry.Onboard there is GPS, a full IMU (providing accelerometer, gyroscope, and magnetometer,...

WEMOS LOLIN32
Log from SumoRobot
All the parts for the new design of the robot arrived. The idea of the new design is to use the mainboard as a chassis for the robot. In front on the plow we have the white area so the children can name the robot. The new robot uses the WEMOS LOLIN32....

Log from Retro-futuristic automobile control panel
My dear readers, today I will fascinate your eyes and minds with this beautiful work of art.Made in a hurry. I will draw the schematics later by hand like usual.The sound system is based on subminiature Soviet Union vacuum tubes and it consists of 5...

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...

Hardware
Log from Custom circuit testing using Intel HEX files
For this project I used a cool little 8085-based single board computer (8085 Minimax) described and graciously provided to me by Ken Yap (thanks again!). I was actually in the process of soldering together the board, and decided to use a verification...

Peak Performance
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
Below is a picture of a patch that gates the input to the ADC so that it is only looking at the value from the EC probe at the end of the square wave pulse, after the initial transient has settled out. It works really well, dutifully recording the voltage...

[E1][T][M] Tetent with 1440px screen?
Log from Tetent [gd0090]
1440x1440px resolution at 125% scalingWhat the screen would look like on Tetent (but sharper). This already makes me think back to my Windows Vista on PSP days, but I'm mainly imagining the future present of quietly chilling in bed while trimming down...

Between the 6th and 12th of June, the Blockfest was held at Ecole 42 in Paris. We were there to welcome new members to the contributors team and work on a very first prototype: how to make 3 independent RaspPi Ethereum blockchain nodes to communicate...

Panel - Part 2 (Electronics and Software)
Log from Vintage Toy Synthesiser
(Original post date: 13/03/16)Last week I posted about the design and construction of the front panel for the vintage toy synthesiser, however another thing I had been doing alongside that is putting together the electronics and software for...

I/O mapping
Log from Arduino Sudoku Solver
D3, D4, D5, D13 are used by the LCD.D6..D9 are keyboard rows.A0..A3 are keyboard columns. I intentionally map these backward so the physical wiring would be pretty. :-)WARNING: Note that the LCD is 3.3V!!!

EC Sensor
Log from UltraTower
EC is the abbreviation for Electro Conductivity. It is used to determine the nutrient concentration of the solution. This factor is essential to optimize the soilless culture. Indeed, the nutrient concentration will not be the same for a seeding as for...
