ServoTester


Here is a really small side project that I developed while working on something else…

I had to test a RC speed controller that I wanted to use to control an electric car window motor, and for the 100th time I was facing the same dilemma: find 8 batteries for my remote control, dismount the RX part from the quadcopter and use that, OR grab the Arduino and write quickly some code to generate the corresponding signals ? Neither of which was actually particularly handy…

So I finally decided to build a small stand alone servo tester :

Stepper motor bluetooth serial driver


First Test using an Arduino (clone) board

First Test using an Arduino (clone) board

Above is the image of my very first attempt of driving this nice little bi-polar stepper motor (M35SP-11HPK) that I had salvaged from a broken Canon printer a while ago.

I have quickly put together a L293D H-bridge with an Arduino board and using the Stepper library was quite straight forward

For the impatient you can see a (probably boring) video right after the break…

SPOKA Night Light & Android – RETURNS


Here’s a quick follow up to my previous post on this topic, to showcase the work of Frank, who inspired by my project (wow… I feel good 🙂 ) went on and created a similar SPOKA light.

IR Remote (Syma s026) dedicated board – V2 – AtTiny45


IRcmdS026_AtTiny45_Final_Side1

Right, the previous post was about creating a dedicated board that can do 2 things:

  1. read and decrypt the IR commands sent by the Syma s026 remote control
  2. send them via a serial link (to the “central” MCU or elsewhere)
