Custom parallel processors in Verilog/FPGA
Details from Custom parallel processors in Verilog/FPGA
Nakano, K., et.al.(refs below) describe two versions of a small stack machine suitable for implementation on an FPGA and they give the Verilog source code on their web site. The design was ported to the DE2 board and extended to have a richer set of...

Chemical Reaction Solver in Verilog -- NO ODEs!
Details from Chemical Reaction Solver in Verilog -- NO ODEs!
For a bimolecular reaction involving two molecules A and B, with concentrations [A] and [B] and a rate constant K, the probability of the reaction occuring (from mass action) will be K[A][B] . Assuming a time step which is short enough to make the probability...

FM-synth, two voice, Markov sequence, music box
Details from FM-synth, two voice, Markov sequence, music box
To synthesize nice sounding musical notes you need to control spectral content of the note, the rise time (attack), fall time (decay), and the change in spectral content during attack and decay. Also it is nice to have at least two independent musical...

FPGA Simulates Analog Computer
Details from FPGA Simulates Analog Computer
The general approach using DDAs will be to simulate a system of first-order differential equations, which can be nonlinear. Analog computers use operational amplifiers to do mathematical integration. We will use digital summers and registers. For any...

Spiking neural net in parallel FPGA hardware
Details from Spiking neural net in parallel FPGA hardware
We can use the FPGA to do fast numerical integration to solve differential equation models of neurons. This page describes a couple of neuron models and their solution by DDA techniques. Eugene Izhikevich developed a simple, semiempirical, model of cortical...

Low bit-rate Speech playback for AVR
Details from Low bit-rate Speech playback for AVR
DPCM (2-bit samples)A version of the DPCM algorithm can be implemented using very little processing time. A 2-bit/sample compressor/decompressor was written in Matlab to encode and to make a packed C header file, and then to do a test-decode. Note that...

BuildLog Laser 2.x build
Details from BuildLog Laser 2.x build
A build of BuildLog.net's 12” x 20” x 4” working size 40W-ish Laser cutter, may vary from original.

DSP on 8-bit microcontroller
Details from DSP on 8-bit microcontroller
One of the most demanding applications for fast arithmetic is digital flitering. Atmel application note AVR201 shows how to use the hardware multiplier to make a multiply-and-accumulate operation (MAC). The MAC is the basis for computing the sum of terms...

Educational keyboard toy
Details from Educational keyboard toy
It's intended as an educational toy for my 2 year old son. The idea is that he plays with letters and numbers and eventually spelling and maybe even math.As mentioned above, there is a PS/2 keyboard attached to an ATMega328-P programmed using Arduino....

Student AVR board
Details from Student AVR board
This page describes a prototype board for the Atmel Mega644 or Mega32 (PDIP) MCU. It includes a power supply, crystal clock, and generous bypass capacitors. A six-pin header allows flash memory programming from an STK500 or AVRISPmkII. All port pins...

Internet Enabled Multizone Thermostat
Details from Internet Enabled Multizone Thermostat
IntroductionAt the head of the setup is a router that provides internet access for the system. The first node is comprised of a chipKIT Max32, Max32 Ethernet Shield and XBee Shield (developed PCB). The second node is the Wireless Thermostat that is responsible...

NTSC Video on Atmel Mega644/1284
Details from NTSC Video on Atmel Mega644/1284
Video GenerationThere are several very good references for understanding how TVs are controlled by a pulse sequence. I particularly liked the Stanford EE281 Handout #7 entitled "TV paint". Also very useful were Software generated video, by Rickard Gunée,...

The Quub
Details from The Quub
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...

Details from Guerrilla MP3 Player / Audio Street Art
Optimized for the best audio quality... i ended up with the wav trigger so i could do 44.1khz 16-bit stereo

100w LED projector conversion
Details from 100w LED projector conversion
This project started some months back. I was given two projectors, one with a bulb, one without. Not wanting to scrap either unit, equally not wanting to spend £100 on a bulb that would be prone to shock and likely to fail, I decided a more serious...
