Cool resistors

As featured on the liveshow, now in ultra high res. A 3 digit adjustable resistor. 10 kOhm potmeter. It's name and number are easy to find online: Bourns 3683s-1.

FIXED: irin resets servo?

I've attached an IR receiver to a servo to use as an IR beacon detector. I'm trying to have the servo sweep through its travel to look for an infrared signal using the "irin" command on a 28X2. I want it to start the servo all the way to the right and pause for an IR signal check. If no signal then increment to the left a little bit, look for IR signal, if no signal, blah blah blah...

My (original) code snippet:

let servo_pos = 70

his  is a non-contact distance measurement module, which is also compatible with electronic brick. It’s designed for easy modular project usage with industrial … Read more

Hello! I'm new here


Hi there. I have seen a few videos from this website. I've even been told a few time to sign up, so here I am! :) Glad to meet you all! Lots of fun projects on here. I've been looking through the Robots and Blog area, some real neat stuff.

I'm a robot builder also, sorta, kinda. I spit out new ones often, so I may not have time to post them in the Robots section. But I really like the active forum here! I'll probably be around often. 

Here's a few links to some of my robots if you're interested:

i made this for fun.it was designed for 6axis & gravity detection. the mercury switch is not perfect,i have to do some anti jitter work. Read more

Arduino code question and problem.

Can anyone help me to take a look of the code following? CODE 1 works fine to have motor runs forward and backward:

Electrical noise affecting Parallax Ping))) sensor

We're working on a "Start Here" robot (Picaxe 28x1 project board), but we fried the Sharp sensor (inserted the 3-pin connector backwards), so a Parallax Ping))) (from Radio Shack) was purchased in its place.  At least we have eyes again, but sometimes it's like Mr. Magoo driving around.

inexpensive motherboard for linux

Hi there!

Is there anybody who knows an inexpensive motherboard yet powerful enough to be able to run Linux OS? I have already dicovered RoBoard and Mini-ITX motherboards, but I am looking for something else if there is any!

To start, I'd like to say this is my first robot, but, since I had electronic- experience, and so many people have done the SHR, and I had a good idea, B.I.L. was … Read more
