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...

Emillotron - part 1 The title is a mix (a crasis) between Emilio (my name) and Mellotron. The Mellotron was used in the 1960s, in the time of the Beatles. In those years, long before “digital music”, someone invented a mechanical system...
I have found the SmartResponse-XE an interesting "Arduino-compatible" device. With BASIC installed and the added "Q" token (alias for PRINT) to allow realtime evaluation of simple math. However, the math functions of "+", "-", "/", "*" all...
First of all, to obtain weekly comics release lists from the ShortBoxed comics API, I developed a web application in PHP running on Raspberry Pi. Then, I used an Arduino Nano 33 IoT to get comics release lists transferred by the PHP web application and...

Programmer Design OptionsStrip-board works well (I use A$8 41 x 144 board), but I did look at using a mini-Mega2560: I used an on-board Arduino Nano as they are cheap (and I have a couple of them lying around) and they provide serial and power.But...
Counting the GPIOs... With the intention of using the Raspberry Pico micro controller, I needed to understand how many GPIOs would be required to carry all of the necessary signals: 16 X Address Lines8 X Data LinesMREQ signalWR signalRD signal....
All documentation for the expansion board is available on the Supercon Badge project page. Of course you can do a ton more than this hardware, but blinkies are always the first step! A Demo: The Hardware: The hardware couldn't be simpler. I added a 595...
References to earlier prototypes have been popping up ever since I ruthlessly slit DVI cables to force DIL8s onto some of their pins a decade ago:https://www.google.com/search?q=EDID+InserterSurprisingly the EDID Inserter hasn't become an off-the-shelf...
I plan on using this bus as the backplane for supporting R&D for my Kestrel Computer Project. Signals are as follows:SYSCON Signals.50MHZ. A 50MHz reference clock generated by the backplane. NOTE: This doesn't mean that the bus has to run at 50MHz; you're...
Introduction Most electronic systems can be explained using this diagram. Systems consist of inputs that connect to the outside world, some form of processing or control and outputs to interact with the outside world. If the system needs...
