So, some holiday madness from Spain. The [first] prototype for an arduino-driven GoTo bincoular mirror mount. The pictures speak for themselves […]

trying to get the crystal changed from 16 Mhz to 20MHz.

So, the next requirement is to be able to programme the chip on the arduino diecimila board, then remove that chip, and place it on a breadboard that will be battery-powered and sit on the mount itself. The chip will receive instructions over bluetooth and then process them (eg turn the Altitude stepper motor 100 […]

capeMirror also needs to be controlled using ‘on-board’ controls (up, down, left, right). Fortunately, it proved pretty easy to programme the Arduino to do this – although this excellent tutorial helped. The tricky bit was the wiring. The Wiring The wiring can be seen on the right. There are four push buttons wired into analog […]

this little sketch along with the vb .Net script below builds on the previous examples, but this time having completed the sketch the arduino sends a message: “[Arduino;Bluesmirf;Baltaz]”. This is then read by the windows .Net application using the SerialPort.DataReceived event in .Net. In short, it appears to my untrained eyes that the windows application […]
