A clock built with eight authentic soviet vacuum fluorescent display (VFD) tubes, a custom designed circuit board, firmware and 3d-printed case It is an evolution of Phalanx. Many of the firmware improvements made for Ameise also trickled down to Phalanx...
The idea was quite simple. Buy a linear actuator from OpenBuilds with a stepper motor, attach a camera on top of it, two tripods below, assemble a control box with some Arduino-compatible, WiFi-enabled board and write an Android application that would...
French article in GNU/Linux Magazine France If you wonder why, just click and read the log. For the what, check Definitions and Draft as well as PEAC vs LFSR for a comparison. The original algo/project name was "Fibonacci checksum" but it later...
IntroductionThe intention is to introduce PIC32 into ece4760 in the Fall 2015 semester. This is a start at understanding how the chip works. The general way to learn this processor is to look at examples which come with the MPLAB distrubution, Use the...
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...
QUUB is an open-source, micro controller system based on a core processor, addressable daughter boards, and remote IO modules. It is a general-purpose embedded microprocessor system, the form factor is based on a main MCU board and multiple stacked...
Basic Localisation and routing is implemented as can be seen above in the video.Speed control - the speed of each track is regulated by a PID using feedback from the quadrature encoders.Directional control - a PID monitoring the heading as determined...
Hunting Primes on Embedded SystemsOne way of finding prime numbers is to use the Sieve of Eratosthenes. This starts with a list of all numbers 2-n. You find the first number in the list, which is prime, then remove all of its multiples from the...
Whilst I never really grew up playing pinball machines (arcades are a different story), I had the opportunity to play a full size, fully functioning White Water pinball at my previous job. I was hooked and wanted to keep playing after I came home. Thus...
So here we have the first set of parts for the ServoStock, a derivative of the Rostock using Closed-Loop control, a whole new com architecture, Servos for drive and NO STEPPERS. Pictured is the first attempt of the single axis using the Vitamins from...
I know the final result video is a bit darker, in person this is not the case :D My camera was set to manual to get the most true image on the first one, half way through (hot glue area) the battery went dead and it lost those settings. I didn't think...
Welcome to the hackaday.io project page for the ramanPi! The ramanPi is a raman spectrometer that I decided to build back in April of 2014 because I needed one for another project and could not afford the tens of thousands of dollars a commercial product...
A quick and dirty introduction to the PyPPMHere are a couple short summaries of the "what" and "why" behind my PyPPM project.Still interested? Awesome! Read on, friend...How an Earth's Field NMR (EFNMR) experiment worksThe first-revision PyPPM...
