The enclosure was made exactly as it was described at http://hackaday.com/2015/06/03/how-to-build-beautiful-enclosures-from-fr4-aka-pcbs/, so I have nothing to add about it. It is more interesting for me how we built DC units then. There were no switching...

Featured on HaD, 03/06/2014.Ever since I saw a YDPG18A mod post where flash was upgraded (unsuccessfully), I’ve been curious about upgrading NAND flash. After I started investigating I realized the upgrade mentioned wouldn’t work, so I called the guy...
One year ago my friend asked me to work on the electronics and mechanics of his lock whose design and casing had been made by a designer friend of him.I made a proof of concept with the guts of a rc toy, a battery laying around and a small reduction...
The staffEvery warlock has a staff and this staff is packed with goodies – soft lights, high lights, fairy lights and cloak color and pattern control that is being done by a lot of software, electronics and wireless modules – very useful lights for the...
I have made lots of MCU based circuit and gadget, but felt some missing piece of knowledge between logic circuit (TTL) and software programmable circuit, so CPU.This time I found a very nice Japanese book, denoting "how to make CPU by TTL"Its ISBN is...
For practical reasons (it's impossible to list everything on the 'net), the "project" is mostly about gathering people from HaD who built their CPU (or at the very least digital electronic devices). Here are some external links for those who just can't...
The PLL is a TB31202 with a serial interface so I used an Arduino Nano module to watch the PLL data and work out how the native processor was communicating with the PLL. After that I intercepted the PLL data to determine what native processor was doing...
Again I would like to write this circuit and ROM image is NOT my original. Just I made PCB files (Eagle files) and will show some fundamentals of how to write EPROM..Before making, please read Grant's 6-chip 6809 computer carefully!!The software, BASIC...
This is a module that #Hackaday TTLers and other CPU makers often need: they can spy on an address or a data bus without the hassles of a logic analyzer. Which is fabulous when developing the #YGREC-РЭС15-bis or the #Discrete YASEP... The PCB acts...
So, I have one of these...... and I have one of these ...... and, of course, I've left my TTL-level breakout elsewhere. The circuit is doing what it's supposed to, but I *really really* want to be able to dump data in to its serial port. So, what to...
The Backpack variant The J1772 pilot line on the EVSE end is connected to a ±12 volt square wave generator with a 1 kΩ output impedance. The line can either be pinned at +12 volts, -12 volts, or oscillating at 1 kHz with a variable duty cycle....
Basics: This clock can display words as well as numbers, it connects to twitter to source words, either random or submitted by twitter users. It uses the camera to send out pictures of things it has displayed too. More details about how to use it can...
Long time ago I ordered several ESP8266 modules (ESP-201) for my yet-to-be-made home automation system. Not long before that time I had Wi-Fi security related project on "big" PCs. Which inevitably brought me to well known Kali system. So, idea to use...
