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...
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...
case is made from plywood found on the streets. there is some 5mm acrylic too, those i was buying cheap a4 size on ebay. wooden frame is held without glue, mostly little 3mm screws. board are mounted on 5x5cm, 10x10cm, 15x10cm wooden pieces,...
This HOW-TO will help you easily set up a PogoPlug to run NetBSD without needing to disassemble the device and solder on a serial adapter. When you're done, your PogoPlug will still be able to be booted into GNU/Linux but will automatically boot into...
The operating system I will describe, called TinyRealTime (TRT) was originally written by Dan Henriksson and Anton Cervin (technical report). (See also Resource−Constrained Embedded Control and Computing Systems, Dan Henriksson, 2006). I extended it,...
An original xbox controller has 8 channels of low-res analog, 4 channels of hi-res analog, and 8 channels of digital inputs.I tied the low-res channels to my front row of pedals. Soldered a wire to a bit of pcb, ran the wire through the resistive...
The arduino library supports A/D conversion at about 13 KHz, not fast enought for a useful audio-rate oscilloscope. Rewriting the acqusition loop to directly access the ADC reqisters speeds up conversion (including loop overhead) to about 688,000 samples/sec,...
After looking over the schematic of a reverse engineered power inverter I thought to myself "Self this is not that complicated". So I set about making my own BAD A$$ POWER INVERTER. My Goals are as follows.1. Pretty Easy to build with normal...
The photo of the horrible wires all over the bottom of the board is from the left channel amplifier board and was taken when I got it. The first thing I did was remove all that and put it back to as near stock as possible (some of the tracks had gone,...
I decided to build a FP with 8-bit exponent and 9-bit mantissa (and with no NANs, infinities, denorms or rounding).The sum of the bit-lengths (plus one sign bit) means that the FP number fits into a 18-bit M4K block word on the CycloneII FPGA. The 9-bit...
Our project was designed for our EECE 276 - Embedded Systems class as undergraduates at Vanderbilt University. The project was developed in C running on an ATMEGA 1280 AVR 8-bit microcontroller. Our application code runs on top of uCOS/II,...
Audio filter implementations All of these implementation use a multiply-and-accumulate (MAC) scheme to compute each of the terms on the right side of the following equation, then divides by a(1), if necessary. Some of the implementations are serial,...
They say you only need to put your AquaFarm in a sunny window shade, and that may work in Southern California, but here in New England, you can't grow much without a decent grow light. Most grow lights available are 1) Bulky 2) Ugly 3) Expensive...
The Raspberry Pi is running Arch Linux ARM from N.O.O.B.S (http://downloads.raspberrypi.org/) with Lighttpd as web server.Yana-server is a home automation home server for Raspberry Pi including a voice controlled assistance called Yana. The voice controlled...
