    Steve's Tetris

    A Tetris clone Implemented in Java

    I've noticed that there are a lot of really mediocre Tetris clones on the Internet, most of which only make it halfway there. That is, most Tetris clones seem to forget things like the Hold Queue, the ghost, hard drop, and especially the more subtle things like the delay between the piece reaching the bottom and the piece actually locking into the Tetris matrix. This program was an attempt to write one single Tetris clone that includes all of those things, as well as added features like the detailed game statistics. http://www.youtube.com/watch?v=jr4ifpWc5I4

    javastim

    An e-stim signal generator in java

    A signal generator generating signals for e-stim purposes. Planned to support windows, linux, and popular cell phone/tablet systems. Will create pulse trains that are mostly zero-averaged to avoid cell damage, allow certain manipulation options (frequency and amplitude modulation in certain ways). Control will be possible via a Java Swing GUI, and/or a terminal like interface on network or serial lines. Will allow 1-4 channels (2-8 electrodes). Output the signal via a soundcard to an amplifier that can output e-stim compliant signals (100+V, current limited to about 100mA, high impedance, short circuit proof). Care to have a potential free output for every electrode (use separating NF transformers). Author claims no responsibility for physical damage from misuse or routing the signal through unsuitable circuitry. Any use happens at the sole risk of the user.
