I just placed an order for new parts, here are the notes so I do not forget why I ordered them...
For the microphone circuit
|The MCP3008-I at electrokit|
I ordered a Analog to digital Converter, this is because I want to try if I can get a higher sampling rate with it than with the built in ADC of the ATmega328 Arduino.
I also ordered a EEPROM memory circuit to test dumping the memory, the ATmega only has 2Kb of SRAM so in order to sample a bigger number of samples I want to try to move the samples to the 64Kb eeprom.
For USB-bitbanging experiments
I´m kind of curious on various bit-banging circuits. I think I´m going to build a USBtinyISP that you can find here: http://www.ladyada.net/make/usbtinyisp/
I got most of the parts and are going to wire the circuit myself but I need the Chrystal and USB mini as well as the level conversion parts.
|A 12.000Mhz chrystal from electrokit|
12Mhz chrystal: Kristall 12.000 MHz HC-49/S 30 pFLevel conversion IC 74HC125N DIP
Zener diods (for level conversions) BZX55C3V6 DO-35 3.6V
A simple to wire USB USB mini-B monterad på kort
I also intend to test the V-USB and perhaps build my own USB to serial as can be found here: http://www.recursion.jp/avrcdc/
