http://bla.thera.be/article/infra-red-guitar-tuner
March 13th, 2010. Two days experimenting with a sensor, three for gathering parts, soldering and thinking about implementation details. Tuner determines string sound frequency by illuminating it with infra-red light emitting diode and gathering string "blinks" with an optotransistor. Sensor required to gather information about string vibrations is built using two parts (4 including resistors):. The same design can be used in collision-evasion sensors I guess. Say we want to tune the string E. I want ...

May 9th, 2010. Random small implementations I did recently. Featuring web clock synchronisation checker, and rocket simulator, (and if I recall anything more I'll put it here. ;p). Javascript/PHP program which measures system time error with respect to the server it's being run on. You can see if your clock is synchronised. Simple line-based UDP communicator written in Python.

Three simple cases of neural networks. January 20th, 2011. Project for university. Neural network for character detection, for stock prediction and for image compression (Kohonen network). Stock 0.1.tar.gz. Has Qt4 interface, matplotlib plots, and Kohonen part uses Cython to speed up operations. Screenshots included. Rest of the article. August 27th, 2009. Rest of the article. Inverted pendulum, balancing robot. October 12th, 2008. It was a very long-timed project, albeit not a very intensive one. Th...

May 22nd, 2008. I've finished a work on my Computer Programming assignment for studies few months ago but haven't had time to publish it. so without further introduction all related files are here. Files include documentation, tarball with a some old version, repository (blaRAY.git.tar.bz2 compiles), 3 poor renders, scene description examples. There is also a file in Polish language (Sprawozdanie.pdf) describing the thing for my CP professor. Probably interesting things to notice. No optimizations in col...

Three simple cases of neural networks. January 20th, 2011. Project for university. Neural network for character detection, for stock prediction and for image compression (Kohonen network). Stock 0.1.tar.gz. Has Qt4 interface, matplotlib plots, and Kohonen part uses Cython to speed up operations. Screenshots included. Network error plot. It's clearly seen that during the training the average network error drops. Some stock closings plot. Back to main page. Add a comment . Hide the comment form [-].

http://bla.thera.be/article/ps3-gamepad-manta-mm821/comment
Simple fix for HID Manta MM821 gamepad / driver. January 12th, 2011. Each gamepad for PS3 seems to need a bit different fix/activation routine to run under PC/Linux. No idea why. I've seen already 2-3 fixes on the internet, but none worked with my gamepad. So, if you have one of the Manta gamepads (MM821 is mine) you can try this program. Download a tarball activate mm821.tar.gz. Unpack it, read README, and compile it. Run compiled program (./activate) and have hope. Back to main page. Add a comment .

http://bla.thera.be/article/distributed-message-passing-network-weespur
Distributed and self-filtered message passing system. February 15th, 2012. I've had recently an idea (inspired by society outcry after the ACTA was signed by our goverment, but not only) I want to share. It might not be particularly original at a glance, but I find its details pretty exciting. Ah, and I've called it. Pronounced: whisper) from the name of the passed messages - whispers. Weespur specification / emacs html. Weespur specification / exported html. Weespur specification / ascii. Add a comment .

http://bla.thera.be/article/modbus
December 7th, 2009. In the meantime I wrote kind of useless software but haven't got time before to publish it. A program to send modbus (ASCII or RTU) commands or terminated text strings over UDP or serial connection. It's object-oriented program written in C which has almost 5k lines. Here's last tarball Modbus-1.0.tar.bz2. And see whole project directory. Back to main page. Add a comment . Hide the comment form [-]. Email (wont be shown on webpage):.
