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

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…

Improve Wireless Doorbell

This is an unexpected project, that might prove one of my (very) few that are actually finished and useful ! 🙂

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.

Lightweight software UART -> custom serial

Software UART to custom serial on an AtTiny45, and then going to the Peggy2 board

7 months ago, in the middle of the winter, it all started with this…

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)
