Arduino is a micro-controller platform designed for ease of use and learning. It allows the creation of electronically controlled projects, whether it be simple blinking lights, a robot or a music generator.
This workshop is aimed at beginners. You don’t needs any previous electronics or programming knowledge or experience. Topics covered include:
An introduction to the Arduino
Using electronic components to build circuits
Input and output
Expanding your Arduino
Price: £45 including Ardunio, £25 excluding Ardunio.
All the electronic components will be provided. If you already have an Arduino you can bring that along and just purchase a kit.
Byvac a small company in Yorkshire has produced this excellent little kit using the DIl varient of the PIC32 proessor which is programable in BASIC via it's on board serial port.
This is a kit of parts so that over 20 Projects can be carried out using the PIC32 IC with a BASIC like programming language on the IC can be purchased on its own if required but this kit includes the IC.
No programmer is needed as all the programs are compiled on the chip from text files. A serial interface is included.
Ideal for getting started using microcontrollers, the full tutorial is on line, see the link below. Learn about input / Output, multiplexing, interrupts, timers etc. Build a voltmeter and a real time clock. The IC is low cost and so can be built into a permanent project when finished (unlike development boards). No power supply required as this comes with the serial link.
Programs you write are initially loaded into the 32K RAM and then optionally saved to Flash to make the device run the project at start up.
I really didn't think the camera would be sensitive enough for a successful Astro camera and maybe for more distant objects the lack of lite/exposure time will be a problem but fear not some one has stopped talking about it and gone and done it with some quite lovely results.
He's doing this on his Celestron NexStar 6" with a 20 second exposure using RaspiVid.
From here he converts the video back to seperat eimages and then uses standard astronomy software to "stack" the images.
What I wonder here is weither it would be better to take a sequence of images rather than an h264 stream in terms of quality.
The only problem I see here is that there's a significant lag between executing the userspace command and the image appearing so you may be waiting quite a while
