I replaced most of the logic board with an Arduino Nano. The only original parts used on the original board is the 12V→240V DC-DC converter, and traces feeding the 5V power through the board. After connecting I checked that shifting values into the anode...
These are my musings on how to minimise and streamline the amount of kit needed for an on-set Datawranglers kit.I would like to build a cyberdeck to use on set for datawrangling.It would be great to hear advise from the community to guide me as this...
Bringing the NE555 into the future also means using modern tools. We'll describe the functionality of the dice in VHDL and use PCBFlow to synthesize the digital description into an implementation based on NE555 logic. At the same time this will also...
Yann pointed out in a comment that a Johnson counter may be a good way to save some gates in the logic implementation of the dice. Currently a simple binary counter is used.To be honest, it seems that I mistakenly thought of Johnson counters being simple...
This is where things get a bit more interesting. I was concerned that it was quite difficult to coerce Yosys into using my custom gate libraries, but in fact it was rather easy. The "cmos" example proved to be an excellent blueprint to creating a custom...
The design currently contains four modules, including: Base module (with NodeMCU, breakout headers, 74HCT125N level shifter and external connectors/spots for DHT22 sensor)Power Supply module (with AC/DC, DC/DC and POE-level power supply options, to provide...
Well, if this project wasn't in "hack territory" before – despite an actual hacksaw already having been part of the process ;) – it's definitely there now!Yesterday, I removed all 32 "anti-ghosting" diodes, and reinstalled them the other way round (except...
For now assume that all tested ICs are having GND at the left-bottom pin (I know it is not always true, but we may add support of other classes of chips later), all ICs will be installed to the bottom of ZIF-socket and we may have DIP14, DIP16, DIP20,...
I decided that interface between ZIF-socket and host machine will be implemented with help of this antique ISA backplane manufactured in 1984 (I bought it for about $20 last month):I cut out it a little to remove part with pull-up resistors, because...
For this step you will need: Length of 20AWG wireDual T-splice wire connectorsM3x8 bolts (x6) We will turn our attention back to the pairs of unconnected wires now which we added to every 6th panel along the length of project earlier to help us inject...
Video Series The video series refactors the CPU from scratch and documents the details along the way. Running on an inexpensive FPGA card. IOP16B - I/O Processor with minimal instruction set Useful for offloading polled I/O or replacing CPUs in...
Platform:1) Using 2"x4"'s build a platform for your derby. I built mine 16.5 inches, but your's may be taller or shorter based on how high or low you want it. The width is 48" like the base layer.2) Using 2"x6"'s build a case for your electronics and...
Step 1: Understanding of Transhumanism - Interviews In order to define what is the best way to become a machine, I have been in transhumanism meetings organized by "London Futurist", the London most influent group lead by David Wood. From those discussions,...
