Woo hoo, Plastics arrive, I can start the build


The plastics arrive, a nice shade of red. However they dont match the standard set of Prusa I2 plastics
so ive got to do a bit of investigation to do to find the relevant instructions.

These are what I ordered from Ebay:

Bench PowerSupply

 

Ive increasingly found I need a better power supply while working on my Arduino projects. 

So here is my version of the standard ATX power supply conversion wrapped in a nice metal case I had laying around.

Sideuino

This is my take on the Arduino platform.

It plugs directly on to the side of the breadboard bringing all the data and analog pins directly on to the board with the 5v and ground rails.
Its my first home made double sided board and in fact only my second home made pcb using the toner transfer method. There are a few bits I can improve on the pcb layout such as movong more of the traces to the top side of the pcb. It took two attempts to get the top and bottom mask aligned but finaly I got them almost spot on.

Key fob camera modifications


The key fob camera will be ideal for my project. It will provide the ability to take a picture or record video.
All I need to do is modify it so that I can control it with an Arduino. To do this I need to electronicaly press the buttons and know what state the camera is in.

I plan to do this by bypassing the buttons with opto couplers and to check the state I will use a light resistant resistor or similar device over the status led.

Nature Camera - Arduino PIR video camera

Having seen a number of nature programs on tv recently and the use of automatic cameras and video recorders capturing images of animals after dark. I wondered how difficult it would be to knock up one of my own.

I can then place it in the back garden or the local woods and see if I can catch a glimpse of the local wildlife after dark.

Android widget connected via the web to Arduino

 

This is my first Android application.

I thought I would combine it with my ongoing weather station Arduino project.
Taking the xml generated by the Arduino project and displaying it on the home screen of my HTC Hero in a simple self updating widget.
