The Binary Encoder The first Working Digital Computer module described in the book was the Binary Encoder. Here's what it looked like: It's job was to accept decimal input from the operator and convert it into binary codes the computer could use. ...
The ClockThe clock is a six-digit HH:MM:SS timepiece using only DDL gates (1N4148/1N4007 diodes) for the logic and display functions (the LEDs are also diodes, of course). The power supplies and currently the crystal-oscillator timebase use more traditional...
Circuit design is like speaking a language. You have vocabulary (parts) made of letters (transistors and gates), grammar (how a few parts interact to provide a macrofunction), sentences, paragraphs... The semantic is what the whole is meant to do. In...
at a multi-day loss for any idea how to proceed, I wrote several draft log entries touching on the concepts I discovered in the last post... Some of those are much more detailed, including some schematics and explanations of the bit-level link protocol......
heh... but only if I transmit only two bytes per second. And it also doesn't handle low baudrates well, which makes absolutely no sense in the software. I'm at quite a loss. Latest theory may have to do with voltage levels... yeah, the blacklink either...
STONE HMI solar charging Solar energy is the energy generated by the continuous nuclear fusion reaction process inside the sun, while solar power generation panel is the tool to convert solar energy into electricity. During the conversion process, we...

Update 3-3-19: Probed. See the bottom. Update 3-2-19 at the bottom. In another weird coincidence, it would seem my van does not, in fact, use CAN-bus, but in fact uses SAE-J1850 PWM (ooh, cool copy-paste result! I'mma leave that.) So, what's the weird...
Background If you have been following Hackaday for a while, you will have seen on numerous occasions the KENBAK-1, regarded by many as the first commercial personal computer. Ten years ago Mark Wilson introduced KENBAK-uino, a reproduction...
This sensor module integrates gesture recognition and touch detecting functions in one piece, and provides an adjustable detection range within 0~30cm. When connected to your microcontroller, it can detect 5-way touch signal and 7 kinds of gestures:...
History Back in 2002 I wanted to time-shift radio programs for later listening and also to listen in the car. Since a computer can automatically record at the appropriate times, this was the obvious choice of method. All I had to do was to connect up...
Arduino LCD display project brief introduction: Some time ago, I found a heart rate sensor module MAX30100. This module can collect blood oxygen and heart rate data of users, which is also simple and convenient to use. According to the data, I found...
Note: this module by default only with 3.3 V level MCU communications, because it defaults to using IIC pin pull up the resistance of 4.7 K to 1.8 V, so there is no communication with the Arduino by default, if you want to commune with the Arduino and...
