These heatsinks should work well for a SN754410 H-bridge IC or other 14/16 pin DIP.  If you've used this please provide some insight as to how well these dissipate … Read more

Gotta Start 'Em Young

I was putting together an order of PCB's to be made when my youngest, CharlieMac, became interested in the lay-out software I was using. I have to admit, it does look very cool when making a board --all those traces and pads, color coded... At any rate, I gave him a shot and he quickly (within 20 min) had figured out how the software worked. Being curious, I drew up a schematic on paper and gave it to him. Pretty simple, just a coin-flip circuit on a 08m. Ten minutes later, he had actually drawn it up... well! He got every connection correct.

Finally broken my robot post virginity. I decided to get an arduino to see what it was all about and was surprised how much quicker you can do things with the high … Read more

I have build this robot in 1994 but I think it is worth to mention it because it is not as dumb as his age may suggest. The robot have two working modes: learning … Read more

Weather station project, Radio silence!

Here's a quick project update: I've been busy with studies, work and other stupid things and I haven't had much time to spend with really important stuff - my weather station project. Now that I finally got more time and spent couple of nights building I got radio silence! Oh ****!

A watched meter never boils

I would love to be able to have continuous readouts from my electricity meter in my home. Such a tedious job is time consuming and tedious. So I need a robot to do that for me.

This is my new project, containing a cluster model rocket with integrated mini DV camcorder and a Picaxe based rocket launch controller with 2 digit 7 segment … Read more

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
