RPN Integer Calculator from Smart Response PE
Details from RPN Integer Calculator from Smart Response PE
There are numerous RPN calculator projects on Hackaday.com but surely there is room for another? The Smart Response PE surplused devices are old-tech but they are just as capable as any low-end Arduino, the UNO for example. I have owned several...

Arduino powered Laser Painter Project [Ravioli]
Details from Arduino powered Laser Painter Project [Ravioli]
The design consists of two servos, mounted in a way in witch one servo pans the other on an x axes, while the other servo tilts a laser on it's y axes. The laser is turned on and off with a transistor, and a camera shutter control is operated by a transistor....

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

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...

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...

Ultra Simple 2x4 Server Rack
Details from Ultra Simple 2x4 Server Rack
A note on dimensions. The magic of "standardization" has firmly ensured that a 19" rack actually has no 19" wide components. Also, a 2x4 isn't really 2x4.I have attached an image which I shamelessly took from http://www.server-racks.com/19-rack.html...

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...

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,...
