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...
In this project, we will build a 2.4GHz Wlan scanner using the nRF24L01 radio board. In this project, the output delivers all the interference and information in the scanned area in the form of ASCII codes. In the project of making this scanner,...
20200731 : cleanup of many dead links... This page serves 2 purposes : share the resources I have created for all those articles (because http://ygdes.com/sources/ and http://ygdes.com/GHDL/ are not the most convenient) maintain a somewhat not-too-inaccurate...
The heavy lifting is done by an ATmega324PA, which generates the video, interprets the PS/2 keyboard scancodes and provides a serial interface. It is clocked at 27MHz. This frequency was chosen because it can provide correct timings for both NTSC and...

For my GPSDO project I’ve opted for a Piezo 2940210 VCOCXO at 10 Mhz. There is a dearth of information on this particular module available online.(A notation notation: I utilize “E” notation to indicate orders of magnitude; thus 1.5E-6...
Using an old Fairplay Scoreboard LED matrix to display scrolling messages (one of which was also for the kiddos birthday, scrolling "HAPPY BIRTHDAY")A PIC 16F870 was used for the controller. The factory controller was ditched as I was unsure how...
Nakano, K., et.al.(refs below) describe two versions of a small stack machine suitable for implementation on an FPGA and they give the Verilog source code on their web site. The design was ported to the DE2 board and extended to have a richer set of...
I recently picked up an old DVD player from the side of the road - a Pioneer DV-363 - mainly for recycling parts. Upon opening I found the VFD display and half the keypad sat on a separate PCB, and used a basic serial interface. I thought...
Features:Wind up rotary encoder with wind up clicking sound effect.External input for button or other trigger mechanismDeep sleep mode when not playing to conserve battery for many years of life on 2 AA batteriesCan hold about 3 - 4 minutes worth of...
From the Latin, "Docta Vox" meaning "learned voice" or something like that according to Google Translate. It sounded cool and I'm bad at naming things anyway. So there you have it. This project uses Processing with STT (speech to text) and TTS (text...
Since I was born in mid-eighties, I've never experienced real 74xx build. Few gates here and there was common, but lager designs were practically unneeded - as microcontrollers, CPLDs or FPGAs replaced need for such as work. But my possession in vintage...
The Input Commands:I wanted to use a 4 x 4 (16) button key pad to input all the commands with a simple / easy to remember protocol (format).Here is the basic command format:Channel@IntensityStart Channel-End Channel@ IntensityHere is the actual input...
Welcome to the hackaday.io project page for the ramanPi! The ramanPi is a raman spectrometer that I decided to build back in April of 2014 because I needed one for another project and could not afford the tens of thousands of dollars a commercial product...
