Using an old Fairplay Scoreboard LED matrix to display scrolling messages (one of which was also for the kiddos birthday, scrolling "HAPPY BIRTHDAY")A PIC 16F870 was used for the controller. The factory controller was ditched as I was unsure how...
The battery in my Lenovo laptop were slowly losing part of it's capacity. The remaining capacity was 69% (good score after 2,5 years) but I need the really long battery time while travelling. The battery statistics according to Lenovo power utility:So,...
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...
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...
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...
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...
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...
CUBEX is capable of the following:- GPS flight mode acquisition - Position reporting using radio (70cm band) - RTTY, DominoEX, THOR- Image data downlink- Power management Unit: Solar charging / Lipo / Low voltage cutoff
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...
Full documentation at http://people.ece.cornell.edu/land/courses/ece4760...The receiver circuit is shown in the picture. The RC circuit acts a low-pass filter on the power to surpress spike noise and improve receiver performance. The RC circuit should...
piculearThis incomplete but slowly progressing project has the ultimate goal of producing a reliable PIC ICSP programmer that just works and can be more readily picked apart, examined, and/or replaced than a comparable Microchip programmer (for instance,...
Features Capture audio input from 1 or 2 channels (configurable)Calculate the noise level, in dB, from every channel, in thrid octave bands plus the LAeq level in dB(A), every second.Write the measured noise levels in a CSV file (file duration is configurable).Send...
is a fully functioning airsoft RC-XD . For the video function I used a gopro with a wifi backpack and streamed it to my phone, theres a bit of lag but it is fast enough for my purposes. the detonation works with a garage door opener hooked up to...
NOTE: This project is gradually improving. It is fully functional at this point, but it could be better.It started as a pen plotter based on the entrails of a printer. It uses a pen to draw paths from a vector graphics file(SVG file). I wanted to make...
I bought this Vette from a friend incredibly cheap, and to be "nice", it needs a few external parts and paint job which I'll be adding after modding. I have various ideas for what capabilities to add to this car. I comes to mind that since I'm not 20,...
