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...
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,...
The system can be broken down into several large sections, which are detailed in the design document below:The central server talks with the nodes either over Wi-Fi or off-the-shelf RF interfaces. Most of the core software runs here. It contains:A web...
by tEEonEIntroduction I love racing games, and along with the Xbox One came Forza 5!The few steering wheels for XB1 are super expensive and bulkyThe XB1 controller is a new device and i was dying to take one apartI had a spare SRW-S1 lying aroundI thought...
Simulated visual systemWe want to use artificial neural systems to teach biological instrumentation methods. The goal is a set of small circuits which behave like neural systems with respect to voltage, timing, and system behavior. This will enable...

Lindenmeyer and Przemyslaw noticed that you could treat the long text strings resulting from multiple replacements as commands to build objects. In two dimensions, the interpertation is:Start at x=0, y=0, facing along the x-axis.Capital F means "draw...
Matlab code considerationsThe following considerations will be illustrated using a Matlab program which computes Conway's life. Parts of the code are explained below.Matrixes and images can be converted to one-another, so display is straighforward. If...
doneNevermind dug out the "feet" and found the hidden screws.. Done (almost) 4 screws pop speaker out cut wires run to 3.5mm mono jack (on order) or ratail, this was so easy feel stupid for even posting but whatever someone may find it helpful.. /out...
The plan here is to build up intuition for HiD representations in parallel coordinates:points -- The basic representation of points as lines in PC.lines -- The observation that lines map to points in PC.planes -- Hyperplanes can be detected visually.clusters...
A technique for sharpening the spectrogram uses information from the phase spectrum to sharpen the amplitude spectrum. The scheme locates simple sinusoids, linear chirps, and impulses at the correct frequency or time with a higher resolution than the...
Opamp circuits:Repressilator: The repressilator is a genetic oscillator (3). Here we build an electronic approximation of the repressilator. Gene expression is represented by the output of opamps U2, U3 and U5 below. Protein concentration is represented...
Making GSM phone utilizing GSM modules is not that complicated. One needs to use MCU with UART and few IO lines and then truckload of patience for writing decent parser of AT commands - that can be nightmare to do correctly. For this construction, I...
The image based scheme we used had several processing steps Video sequences were shot at either 30 fps or 500 fps. The high-speed sequences were decimated by two in time for analysis. Frames were cropped so that the animal was completely within the frame...
The controller is a PICAXE-14M which uses a ULN2803 darlington driver to drive the LEDs.On my car, there is no constant 12v supply to the tail lights, so I designed the circuit to operate in two modes. When the controller sees that the tail lights are...
