Recommended parts to have on hand? #18

It would be nice to have a recommended parts list to have on hand so that people can construct some basic bots. I know it's not practical to have everything for every possible combination but a list of the basics to have would be good for organizers.

What I plan to have on hand already at the event.

Soldering station / iron
couple spare arduinos
wire cutters
Pile of LED's
Medium full rotation servos
Medium servos
Infrared proximity sensors
Slide pots
Snap action switches (like whisker switches)
Pile of resistors
Few breadboards

I'm thinking wheels of some kind might be good to have on hand? Maybe 3d print some before the event

@dshaw will probably be able to tell you in much better detail all the things that he had at the first Hardware Hack Weekend, but at JSConf, we had a whole bunch of Sparkfun Inventor's Kits, as well as more servos and LEDs than you can count.

Some of the biggest things we wished we'd remembered to get before the NodeBots event:

Batteries
Arduino wall adapters (important for anyone who wants to power more than a couple of servos)
Proto boards (if you're going to solder, you should have something to solder to, no?)

Other useful things:

Popsicle sticks (of different sizes)
Spare cardboard
Glue sticks/Glue gun
BOE Bots (for those who don't want to do less hardware and more software - perfect for sumo bots)

additional essentials!

transistors — 100x NPN 2N2222
photoresistors — 20x GL5537
capacitor kit — 33 values, 645 pieces
laser diodes! — 5v 650nm 5mW
RGB LEDs — 12x common anode

less essential, but a lot of potential: Ultrasonic sensor

Transistors are great for allowing someone to hack existing buttons to be controlled by arduino. Photoresistors can be used in combination with RGB LEDs to create a rudimentary color sensor.

Lasers are just lots of fun.

Would this be a good introduction to both arduino and johnny five? I am wondering if they play nicely together. http://www.adafruit.com/products/749

@heavysixer indeed. We had 10 of these at JSConf. I even proposed to my wife with one ;)

Awesome @rwldrn, did she accept with her own bot?

rwaldron commented 11 years ago

@heavysixer no, but she did say "yes, I will marry you" in a robot voice :D

heavysixer commented 11 years ago

@rwldrn even better.

@rwldrn hmmm good idea.. mwahahahaha
