The S/EA-X Cyberdeck
Details from The S/EA-X Cyberdeck
OVERVIEW This project is a modular Raspberry Pi-based cyberdeck that builds upon the "detachable module" concept that I explored with my original Ulfberht+ Cyberdeck. However, instead of a simple detachable half-keyboard that connects with an exterior...

RPI Pico RF Fan Controller
Details from RPI Pico RF Fan Controller
The process: The RF commands were learnt using the fan remote and SDR-Sharp software with a USB to RF adapter tuned into 433MHz. Each button press was recorded and saved as an audio file. There were 7 commands to learn - 6 speeds, and off....

Maker Faire and project update
Log from 4 bit computer built from discrete transistors
a lot has happened since the last real project update, for starters I took this project to Maker Faire, photo:I had a great time at Maker Faire and got to have a lot of interesting conversations with a lot of interesting people.now, on to the interesting...

SDIO
Log from Nyx: Edison - FPGA Devboard
Reverse EngineeringAs I mentioned in my last post I decided to use SDIO as an interface between the Edison and the FPGA on Nyx. The only problem is that in order get the information to design a proper SD host controller and SDIO device you need to pay...

More 2369, with more caps !
Log from Hackaday TTLers
Back to the workshop for the revenge of the return of the son of the Vintage Ring Oscillator ! This time with a new ally : the ceramic capacitor ! TL;DR : it's 60% faster ! But the V/F curve might look different from @Tim 's experiments... As usual,...

Prototypes Arrived!
Log from TinyFPGA E-Series
After months of waiting the TinyFPGA EX prototypes arrived a few days ago! I was so thrilled to finally try them out that I forgot to write a Hackaday.io post about it. The prototype run was for one panel of 8 boards. The first...

Learning FPGA And Verilog-Beginner’s Guide Part 2
Details from Learning FPGA And Verilog-Beginner’s Guide Part 2
Neso – Artix™-7 FPGA Development BoardLearning Verilog itself is not a difficult task, but creating a good design can be. But we focus on simple designs here and I will try my best to explain things as simple as possible. If you had been programming...

A native NeoPixel interface for the NEORV32
Log from The NEORV32 RISC-V Processor
The cool thing of having a soft-core processor is you can add exactly the features you are wishing for. Some days ago I got a hint on the WS2812 LEDs, which are used in Adafruit's awesome NeoPixels. The interface is quite heavy when it comes to timing...

Existing Tools to build on
Log from VHDL/Verilog to Discrete Logic Flow
Automatic synthesis of digital circuits has been the domain of very expensive electronic design automation tools in the past decades. Since a few years, there seems to be considerable momentum to develop and make available free toolchains for ASICs and...

Synthesis and Technology Mapping
Log from VHDL/Verilog to Discrete Logic Flow
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...

Apollo Guidance Computer
Details from Apollo Guidance Computer
Why build a replica of the Apollo Guidance Computer? I have always wanted to build a computer based on TTL chips ever since that college lab course that taught the use of TTL chips. During my career as a software developer I was fortunate enough to work...

A detour to Pano Logic G1 (4) - USB
Log from VerilogBoy - GameBoy on FPGA
I promised that there would be an update about the USB, here it is. This update would only talk about the USB 2.0 Host on the Pano Logic G1 devices with ISP1760 USB host controller, so it is probably not applicable to other platforms. The goal here is...

Back and Forth Project Scope Discussion
Log from Project Boondock Echo
KC and I had several back and forth messages through email to determine the scope of the project. (Lots of detail, but you can see the general thought processes below): KC -- check this out: https://github.com/sharkrf/srf-ip-conn-srv And Openspot...
