Here's the circuit used to drive the LED. A PIC12LF1571 periodically wakes to pulse the gate of an N-channel MOSFET. The MOSFET allows current to build through a 1 mH inductor; once the MOSFET shuts off, the inductor discharges through the LED to create...
I finally started to do something that I've been wanting to do for over 20 years: use a logic analyzer to figure out how the DCC-175 communicates with the PC. It didn't go so well but I fixed my mistakes. If you want, you can skip this...
I know it's been quiet in this corner for a long time. But lately there have been some exciting things happening to this project. So here goes! ---------- more ---------- First of all, the most exciting news: I found a cable that fits...
Since the beginning of this project we have designed and tested different electronic designs, this log compares them and highlights their features, cost and dimensions. We recently design EJA M v1.0 with the goal of replacing the previous designs,...
LEDBOY Instructions for programming and using functions. Below you can find a tutorial on how to use all the functions of the device as well as hardware information. 1. Install drivers for the serial programmer and be able to upload code. -Download...
RGB Pumpkin wall light Hi, I am Vishal, I make amazing things on my youtube channel please checkout. Halloween is about to come and already all are doing their preparations, in my previous project I made an Uncanny eye pendant, Which is already rocking....
I'm sitting down to start creating a video I started a while ago and never finished. I'll be doing it on the Pi 400 of course. Pi 400, Vilros Pidock 400, in ear monitors, kdenlive, Audacity, extra patience. The first step is to review all the footage...
The beginnings of an era It was the winter of 2003, pretty much this time of year, 20 years ago. I was in my last year of technical high school. I was learning lots of electronic tips and tricks and I was also experimenting with programming...
On the one hand, I feel lucky to have been born where and when I was, which was in Sheffield, Yorkshire (God's own county), England, in 1957. Due to my good fortune, I got to see the 1960s firsthand, albeit through the eyes of a young lad. I also got...
Prototype delays due to electronic components shortagesAs already stated a few times, we are still victims of the electronics industry supply-chain difficulties. Back in July, we informed you that “98% of more than 2000 components are now secured...
My Inspiration When I was designing Think-a-Tron 2020, my plan A was to use an ESP32-CAM to read QR codes off the back of some business cards. I did have a backup plan though. I ordered a GM67 Bar Code Reader Module from AliExpress just in...
(Original post date: 24/01/16)In my last log I talked about the implementation of the electronics needed for adding a MIDI interface to my vintage toy synthesiser. As a suitable follow-on, within this post I thought I'd talk in-depth about MIDI message...
Introduction In this project, I will show an easy way to get started with TinyML: implementing a Machine Learning model on an Arduino board while creating something cool: a gesture recognition system based on an accelerometer. To make the experiment...
Will S Merkens12:36 PMI have stuff stored on 8mm tape and it's still readable Nick Tonn12:36 PMWell, i still disagree about the theory that drives are made specific for MFM and fail at GCR. PixelDud12:36 PM@deʃhipu My guess, SSDs. Tom Nardi12:36 PM@deʃhipu...
How the Original Think-a-Tron Works Before you can begin to understand how Think-a-Tron works, you need to see one actually running. This video does a great job of explaining how to operate a Think-a-Tron. Having seen a Think-a-Tron in action, would...
