A project log for Working Arious motion tracker

Working motion tracker from the video game Alien: Isolation

Since the device in the game is "low tech" I'll try using only jelly bean components to keep the level of technology true to the game/move.

Updates:
- Finished the first set of spice simulations for the HB100 preamp, spice file has been uploaded above
- Model is still far away from being printed, it will take another week to finish printing all of the parts

Thoughs:
- The HB100 application note shows using the LM324 opamp, for lower noise the TL074 could be used, and also running it at a higher voltage
- Looking on the web, I found a FFT library that seems to be able to work on a PIC18F mcu, so the PIC18F4550 could be used
- The UTFT LCD used has tons of Arduino libraries, but none that I could find for PIC, I'll have to adapt them to work in plain C on pic
- For sound effects, I'm considering using the SAA1099 sound chip, LM358 amp and 8 ohm speaker
- Considering the MPC A/D IC series as A/D converter IC
- NiMh or NiCd batteries could be used instead of Li-Ion

Awesome! I like the "low tech" aspect because I cannot solder SMD. 

With low tech you mean through-hole components, don't you?

  Are you sure? yes | no

Yes, TH components and jelly bean parts like TL074, BC series transistors and such.
