Quark-85 Demo Kube - 184 x 240 VGA with 8 Colors and Sound on an Tiny85!!
Your work has inspired a desire to start learning assembly language for the avr.  Im am currently counting clocks in the AS7 simulator with C' compiled code in hopes to get a...

Seeking tips on interfacing to 24VDC
Adding a resistor to the logic high input of Q1 divides the voltage down to safer levels at +5.6v.

Seeking tips on interfacing to 24VDC
I just designed a quick logic converter that should suit your needs, depending on your data speed you may have to or can tweak the resistor values. I am not sure of your current...

Seeking tips on interfacing to 24VDC
This rs-232 interface IC may work for you, It can handle +/- 30v input and have an output logic voltage of vcc. Although the DS14C89AN ic shows it  inverting the...

SPI Master/Slave select, MSTR not setting *Newb Gotcha(me)
I will try to clean it up and post, however i think i do now understand something. I can get the MSTR and SPI to work with sending data out of the MOSI port as long as the SS line...

SPI Master/Slave select, MSTR not setting *Newb Gotcha(me)
*EDIT, had MISO and MOSI mixed up. ***I am now seeing the data being clocked out of the MOSI/PB3 pin.  So im better on track with whats going on.

RF noise generation & digital clock considerations
I would love to get a spectrum analyzer and run a sniffing probe around circuits and around the house. There is a cheap way to get started with some USB dongle RF spectrum...

New - ATmega1284p Arduino R3 with integrated DAC, headphone & op amp output, and Microphone amp input.
Was the price that much of an issue to go for a 16 bit dac instead of the 12? As far as i know there are no 12bit variables to save space, your still using up 2bytes of data right...
