Did you have to implement your own board ID system?<br/> <br/> <br/> Actually, except for the RS485-Relay PCB, all of them were built 1- or 2-off. ...

Re: Raspy Juice Expansion Board:

<t>Minor update: OK, today I was supposed to write an AVR module for the RS232 SW UART of Juice and use that to test the on-board PCF8523 RTC. Instead, after the SW UART got working with TeraTerm, I got distracted and wrote the control for the 4-port RC servo interface.<br/> <br/> <br/> <br/> Former...

Re: Raspy Juice Expansion Board:

<t>Hi all,<br/> <br/> Just another minor update: Whilst I am load-testing the partially-stuffed Juice PCB#1, I've managed to fully solder up 2 more PCBs and written a blinky-LED test program for its MCU.<br/> <br/> <br/> <br/> (Sorry: poor movie conversion quality -- more practice needed).<br/> <br/...

<t>Va-va-vrooom: Greased Lightning! Something I've always wanted!!<br/> <br/> There's no mention, but if you can squeeze in: please break out RasPi's console through a RS232 level translator. It doesn't have to have a clunky DB9 connector (I dislike them anyway), just a micro 3-pin JST will do and l...

Re: Raspy Juice Expansion Board:

<t>hzrnbgy said: <br/> <br/> <br/> Just use an MCU for now (Arduino/AVR/PIC/Cortex etc), build the firmware for the RTC and other peripherals you might have, and have the RPi talk to the MCU via a more standard communication port such as serial. ...<br/> <br/> <br/> Thanks for tip, hzrnbgy.

Re: proposing a name for R-PI expansion boards.

How about:

"Slices" or "Slice of Pie" ?

Re: Raspy Juice Expansion Board:

<r>Hi people,<br/> <br/> Like most of us, I'm still impatiently waiting for my Raspberry Pi. I've ordered mine after the launch sold-out date and I suspect it will come even later. I'm really waiting for two things: my RasPi, and my self-designed expansion PCB blanks, which I call Raspy Juice.<br/> ...
