Update: Meanwhile the video of the talk at Hackaday Europe is online: And there is an article on Hackaday.com https://hackaday.com/2026/07/16/hackaday-europe-2026-build-a-cable-modem-for-your-arduino/ Documentation for the project shown at Hackaday Europe 2026 in [ ]
This is a quick guide to gaining access to a large variety of TI parts in particular operational amplifiers in LTspice. We re going to export the SPICE macro [ ]
Motivation Guitar effect pedalboards If this post is for you, I guess I don t have to explain this concept in great detail here. Most of us have a USB [ ]
TLDR I built a relatively simple, cheap, and most of all maker friendly Constant Fraction Discriminator for high precision photomultiplier (and SiPM) timing applications. I wrote a paper about the [ ]
TLDR I discovered that YosysHQ s oss-cad-suite now secretly supports code entry not just in Verilog but also in VHDL. (Update: well I looked at older releases and VHDL support was [ ]
Motivation This is a very short one but I felt like sharing this with the world. I was playing around with the humble long-tailed pair transistor amplifier in LTSpice. [ ]
Motivation Sometimes you just barely get away with the number of available microcontroller GPIO pins to implement the desired functionality And then you discover that you have no more [ ]
Demo Video Introduction Earlier this year I wrote a post about how to build a simple shortwave receiver with nothing but widely available hobbyist electronics parts, i.e. 74HCxx ICs, standard [ ]
So, I was simulating a circuit in LTSpice and I wanted to use an 4000-series IC. Someone probably did that before, right? So I googled and found quite some posts [ ]
Introduction Heya. So I found people building perpetual self-exciting pendulums (pendula? pendulae?) and showing them off on youtube. Nice 🙂 So far the most elegant that I know of seems [ ]
