- 15:50, 4 January 2009 Michai talk contribs uploaded File:Michai 015 schem.jpg (JTAG-toy schematics, done in gEDA's gschem. Nothing interesting here, really. )
- 10:02, 2 January 2009 Michai talk contribs uploaded File:Fishie.jpg (A very detailed drawing of a fish. Well done. At least it's a happy fish.)
- 23:39, 30 December 2008 Michai talk contribs uploaded File:Michai 013 board and beer.jpg (Ooooh, how cute - it al started with some components and of course beer, Creator of Ideas. ...Actually the bitstream-idea came from Jan ;-))
- 21:25, 30 December 2008 Michai talk contribs uploaded File:Michai 013 old and new board.jpg (Old (right) and new board, unfortunately without clamp-diodes and series-resistors, but a more or less exact copy of old one.)
- 19:45, 30 December 2008 Michai talk contribs uploaded File:Michai 013 all.jpg (Dual channel pulse-generator; basically takes 24V and a serial bitstream @ 115k2 8N1, 2 bits per sample (1 bit per channel), to generate an arbitrary 48 kHz pulse train. Assuming your UART doesn't have holes in between frames, that is...)
- 12:03, 28 December 2008 Michai talk contribs uploaded File:Michai 014 finished board downside.jpg (finished interface-board, solder-side)
- 12:02, 28 December 2008 Michai talk contribs uploaded File:Michai 014 finished board topside.jpg (top side of interface-board with all wires and thingies)
- 16:44, 27 December 2008 Michai talk contribs uploaded File:Michai 014 swap ab.jpg (using 2 1-of-2 multiplexers to swap aux A/B lines)
- 16:43, 27 December 2008 Michai talk contribs uploaded File:Michai 014 power.jpg (LM317 as power regulator; one for MCU, one for rest of IC's. MCU pulls a bit too much current perhaps...)
- 16:41, 27 December 2008 Michai talk contribs uploaded File:Michai 014 mcu.jpg (ATmega32 with all line labels (and yes, every digital I/O-pin there is used))
- 16:39, 27 December 2008 Michai talk contribs uploaded File:Michai 014 dio.jpg (digital I/O circuit for 1 line; open-collector input/output on Flow-X side, DIO0..7 input/output or aux A/B input on interface-board side)
- 16:37, 27 December 2008 Michai talk contribs uploaded File:Michai 014 ctrsel.jpg (selection of 1 of DIO0..7 as MCU counter-input)
- 16:35, 27 December 2008 Michai talk contribs uploaded File:Michai 014 auxsel.jpg (selection of aux (A/B) signals to assign to DIO0..7)
- 16:34, 27 December 2008 Michai talk contribs uploaded File:Michai 014 ain.jpg (analog current/voltage input circuit, with I/V selection through relais)
