Dice reader isn't really robotics, but there's no electronics section!

Nice work with the iPhone apps, Stewart!
Now if you could port that over to the new Nokia platform and hook it up to an Arduino, you'd win a lot of fans, I'm sure! Steve could tell you more about the new Nokia kit - it's in pre-production at the min…
I use Oshonsoft a lot. It's a BASIC language, but includes a real simulator, which makes debugging a doddle. The guy who wrote it has also come up with a programmer and some hardware for burning code to chips. For a couple of quid, you could probabl…
Tom,
re: PIC programmer - the one I use is a K149. It's a cheap, Bulgarian clone of a genuine PIC programmer, but has the added advantage of using a PIC as firmware for programming. It's exactly the same as one of these:

Nice work Steve - I've just spent about three hours writing up how to build something like this using a PIC! Copying and pasting a link would have been much easier....
Go to www.buildbrighton.com and follow the link to the Google Group on the homepage.
Tom - are you a member of BuildBrighton? Get on the Google group for frequent updates of what's going on each week!
Tom, are you coming along to the meeting tomorrow (Bonfire Night)?
I'll bring along my spare Pic programmer for you (it's quite old now and I haven't updated the firmware, but it's perfect for 16F type chips) which you're welcome to, if it works for…
You may be in luck - I found my old Olimex PIC programmer at my cottage in N.Wales the other day. It's still running old firmware, but should be fine for any of the 16F range. I could bring it along to the next Thurs meeting- bring your laptop and w…
I'm not quite sure what "start at the top" means, but it sounds like you need to use a flag or toggle somewhere - once a pin is set high, it should "latch" so that it remains high, until a pulse width of less than 2000ms is received, then latch off…
Schema added (dice_tray.jpg)
Details of how the reader/tray could work (I hope!)
http://nerdclubuk.blogspot.com/2009/10/cubedice-tray-holder.html
Allows individual trays to be daisy-chained, each one containing its own PIC18F2455
We've discussed a PCB-building session in the buildBrighton group - maybe something we could do on a robotbrighton night (or maybe open the session up to non-buildbrighton members). Might be of interest to you, particularly if you're thinking of mak…
Data from the cube to the reader isn't a problem- the cube just "broadcasts" and when the reader gets two identical, consecutive reads, it treats it as ok.
The reader to the PC shouldn't be a problem either - we could use the same technique: broadca…
That sounds great so the final packet format from reader to PC will be 5 bytes:
\0000 0000 \ 0000 0000 0000 0000 \ 0000 \ 0000\0010 0001
| | | | |-> Hex 21 or '!'
| | | |-> Orientation
| | |-> Face ID
| |-> 2 Byte Cube ID
|-> Array position
Which…
Looks good - there are two "packets" of data flowing about here - one from the dice to the reader (which is just the cubeID and the faceID), then the reader can append the orientation (n,s,e,w) and the array location (by cycling through the pads, th…
Hi Chris,
Just thought I would add a document to reflect my thinking - basically I wanted to get some things on paper as any comments or suggestions very much appreciated.
Cheers
Ben
