Tutorial - Wireless XBee/AVR Bootloading
This is really excellent! I’ve been working on the problem of wireless sketch uploading for the past few months and I think I’ve come up with a good solution. It works at any upload speed and is tolerant of transmission failures. It doesn’t require bootloader modifications – uses the standard optiboot bootloader. It’s cross platform and supports xbee, wifi and nordic. The project is on github https://github.com/andrewrapp/arduino-remote-uploader

This is just an ok relay. The coil resistance is 60 ohms so it is not technically Arduino safe (83mA). The voltage drops when the relay is on and screws up my analog readings. The leads are kind of flimsy as well and don’t stick in a breadboard. I like the Omron that SparkFun carried before better.
It seems to work for me too but it drops the voltage about 0.05 and messes up my analog readings. There may be other side effects too

I ordered this but received an omron g5sb14, which is actually a better relay, so pretty happy with the mixup.
Tutorial - Rebel Triple Play with Driver Assembly Guide

So would I need about a 2A power supply (650mA per channel)? Since the chip says up to 30V, could I use a notebook power supply ~19V?

Will the schematic be available at some point?
Great tutorial. How are we powering this guy? Didn’t see anything mentioning the power supply. Thanks
