This is going to be a retrospective on what has been one of my most enjoyable projects to date. Looking for a way to keep my ever growing electronics workshop in check and to make the whole lot portable I came up with the idea to use 19" form factor...
USB InterfaceThe USB interface is all done by the PCM2705 IC. When the DAC is connected to a computer it recognizes it as a USB sound card and no manual installation of drivers is need. The DAC can control playback on the computer with the following...
The launchpad is an array of 80 buttons, and 160 LEDs, two per key. It's not touch sensitive, but all the same ... There are five 74HC164, and three 74HC165 inside. 164s (serial to parallel) drive the LEDs, and 165s read the state of the keys. The matrix...
The C64FC is a real-time reprogrammable cartridge for the Commodore 64, allowing you to upload programs to the C64. Software can be uploaded as a complete image, or gradually patched on demand, all while the C64 is running and executing the code.The...
The emulator is the product of playing around with "bare metal" coding on the Raspberry Pi.It's written in C and assembly and boots in less than one second, which is pretty close to the real deal. No USB keyboard support yet, to interact you need...
Aquaponics (pronunciation: /ˈækwəˈpɒnɨks/), or pisciponics, is a sustainable food production system that combines conventional aquaculture, (raising aquatic animals such as snails, fish, crayfish or prawns in tanks), with hydroponics...
2015 : 1 x GloRoll. A 8' diameter steel and LED lit sphere that you can climb into. Think "atlas spheres" from American Gladiators, or if you don't want to youtube it, a metal -human sized- hamster ball.Now, not just a few glow bits, 1024 RGB Leds (yes,...
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...
OVERVIEWUsing 470 WS2811 LED strips, and a Teensy 3.0 to drive the lights. Currently playing pre-rendered animations generated in Processing (for the plasma animations) and a C# app that extract video data and compiled it into LED data. .VEST CONSTRUCTIONThe...
Prototype on YoutubeThis project is a work in progress. It uses Chainsaw blade sections wrapped around the original belt drive shaft powered by a cheap $20 craigslist treadmill. Only the frame that houses the motor, belt and belt pully set on top of...
Ultimately, what i want to get to is a stupid-bright flashlight. I simply want to drive this element at peak output, with decent collimation in a handheld (and possibly weatherproof) form-factor.
It's quiet and fast.It will take 10-40 hours of your life.Your toddler or his friends drawing on it won't ruin your day. This revision has worked flawlessly, with no further adjustment and with daily use, for almost 2 years now.EDIT: 3 houses and almost...
Build an Arduino powered and web enable voltage and current system to monitor power coming in from my solar panels, Power from the charge controller to the batteries and power from the battery to the load.This project is built for 3 ports, but...
