I am %100 convinced that this was a total scam by Sparkfun. What a better way to get free server testing, extensive viral marketing and attention. The best part is that we have no way to verify if they actually gave away $100k worth of stuff since they are a private company. All they had to do was a...

Just wondering what the recommended spec was for an led used with the 4x4 button pad?

e.g. What viewing angle? luminosity (in mcd)? size (3mm or 5mm)?

I just received the RGB led matrix from Sparkfun (sku COM-00683) and I am a little frustrated that I can't read the datasheet since it is a poor scan. Does anyone have a better copy so I can read the column pin assignments? Also the data sheet if for the common anode version not the common anode typ...

discrete oled/pled

I was wondering why there are no discrete 9e.g. 3mm, 5mm etc.) LEDs made from OLED/PLED? I have only seen OLED/PLED display matrices but the large viewing angle and low power consumption of these technologies would be useful for discrete components as well. (especially for control panels) maybe ther...

Which AVR for developing midi applications etc.??

I am looking to start devleoping midi controller devices, mainly ones with large arrays of buttons and LEDs (I would use a serial LED matrix driver). Three questions: 1. Which Atmel chip (or any other brand) would you recomend investing time and money on?? The guys from Monome are using the ATMEga32...

yeah I plan to build my own Monome. It would be an advantage to buy pre-made pcbs for the button contact pads (not sure if home etching is good enough for this type of thing). If they were 4x4 grids (like the PCBs shown in the photos for the 4x4 button pads) and they could be tiled to make larger gr...
