DorkbotPDX group ordering

The Group Order is on hiatus.  If you'd like to pick it back up, please let us know!

Order spreadsheet is Here Orders go out to: Mouser Digikey MiniCircuits please consult the Recommended Parts Page before ordering, the more commonly a part that performs a particular function is used, the more people will buy it. the more people buy a part the easier it is to get a bulk discount on a particular order.

DorkbotPDX meeting monday, april 14th, 7PM @ NW Lucky Lab

Ok, sorry if this spiel sounds familiar... I'm going on fumes at the moment and just wanted to get this out:

It's time again to break out the breadboards, shine up the solder joints and light up the LEDs with your good friends in DorkbotPDX. We'll be meeting once again to mull over strange ideas (involving electricity, of course), hash out plans for world domination and, as always, drink beer. Come join us, bring along a project if you have one and can fit it in your preferred mode of transport, and make yourself known to your fellow Portland dorks.

When: Monday, April 14th, 7pm

Serial --> LCD

Last weekend I built an RBBB board that I bought at DorkbotPDX 0x01. This is the cheapest way to get into an Arduino that I know of. And pretty much the cheapest microcontroller setup you can get. Thanks guys who put these kits together for us locally! I had never done anything with Arduino before (hardly even with microcontrollers) so this offered a low entry fee and great support.

I had some 2-line LCDs I had bought a few weeks ago from Electronics Goldmine for $1.79. They aren't backlit but they are so cheap it just seemed like a good thing to have. One painful thing about Hitachi 44780-based LCD displays is that they use a LOT of IO pins to display stuff. 8bit mode uses all of the digital pins on the Arduino. 4bit mode still uses a lot. I saw some other solutions like using a shift register to bring it down to two pins. But the simplicity of of Serial LCDs was really appealing, so I thought I'd rig one up using the RBBB as a controller. Any future projects that need an LCD can then just talk serially to the Arduino LCD controller and very little is needed to make things work. [1]

Videos from DorkbotPDX 0x01

Thanks to the wonderful efforts of Mark, Jason and Jared, we now have videos up of the proceedings from DorkbotPDX 0x01. Check them out here: http://www.vimeo.com/album/10961

Also, there's now a Vimeo channel for DorkbotPDX, too, which will be the place to see all sorts of videos from the various goings on of our fine group: http://www.vimeo.com/dorkbotpdx
