Arduino Cheat Sheet V.02

Thursday, April 22nd, 2010

I really love cheat sheets. In a lot of cases they can take the place of an entire manual. So I was surprised, given its popularity that I couldn’t find a single-page reference for the arduino online.

I tried to make a sheet that captured all the things I hit the reference for while programming. What data type does the millis() function return? How long till that overflows again? How large can a long get? What baud rates can the serial handle?

Any other things you’d like to see added, send me an email and I’ll stick them on Rev 3!

Edit: Just did some minor mods suggested by people. Here’s V.02b

Small version. Use PDF for printing purposes

Rocket Car Day! Photos and Vids

Monday, April 12th, 2010

For those of you that haven’t been following, we attended Rocket Car Day 2010 on the weekend. This is an event where everyone cobbles/crafts/hacks together the most baddass vehicle they can, then crams a rocket engine into the back and competes for honor and glory!

Some people spent a lot of time on their cars:

Others less so:

The K-t event

Unsurprisingly at such a geeky event, RnD members were there in full force. We even had our own race!

(Note the swanky new lab coats, with RnD embroidery )

The RND possee and their cars

Here’s a couple of videos of the cars:

Sorry for squealing at the end of the vid, but I really wasn’t expecting to win against those other cars which were, frankly, better than mine :)

Special shout out to Big (Iain) who made his own custom arduino & digital compass powered car! We were all sorry to see it was short lived.
