Network Amplifier
Details from Network Amplifier
I bought an XMS amplifier from a friend years ago and although it was serving it's purpose I got quite frustrated with having to toggle the loudness feature every time the input was changed. This was the beginning of what has now become my network enabled...

Pinstax: 3D Printed Instant Pinhole Camera
Details from Pinstax: 3D Printed Instant Pinhole Camera
I've been busy with other projects, summer and the day job, but here's an update on the Pinstax. After weeks of perking this project through my brain, I enjoyed some frenzied productivity as ideas came to 3D printed reality. One of the problems...

Toy Claw Machine
Details from Toy Claw Machine
The idea behind this project was for my sons birthday party. He wanted a robot themed party, so I figured this would be the easiest to build. Similar to the commercial claw machines, the idea is to grab a toy and successfully get it transferred over...

Speed up pkgsrc on retrocomputers
Details from Speed up pkgsrc on retrocomputers
This HOW-TO explains a quick and easy way to speed up NetBSD pkgsrc compiling on retrocomputers. It was written because there are altogether too many distcc how-tos which are complex, require special build environments or make assumptions without explaining...

OCXO Sensitivity Measurement
Details from OCXO Sensitivity Measurement
For my GPSDO project I’ve opted for a Piezo 2940210 VCOCXO at 10 Mhz. There is a dearth of information on this particular module available online.(A notation notation: I utilize “E” notation to indicate orders of magnitude; thus 1.5E-6...

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...

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...
