Not sure if I should blog this, or post as "Something Else"?
Been doing a lot of electronics stuff, I still don't know crap, but I solder pretty good ;)
I got this cool new board (RoboPi) that takes an 8 core Propeller chip and makes it robot friendly (adds 8 Analog I/O's) and interfaces with the Raspberry Pi linux board (via serial).
So the Pi can program the code to the Propeller, and they can both share info via serial. Its a great combo, as the Pi has a bunch of things that the Prop doesn't, like USB that supports just about anything you plug in, so that gives my robot wifi, FTP, etc, and SDCard storage. So now I can remote desktop into my bot, make changes to code, control, etc. I have a long way to go on the coding for all this....
The RoboPi board was $25 from a guy in Canada, it included all the small parts, I had to supply my own Propeller chip, but I had that already. It was about 280 solder joints once done. Took some linux tinkering to get it all to talk, but its working now.
The Pi was another $38 from Amazon. I want to get more and use them to do some internet home automation, like a garage door/lights monitor.
I also finally finished(?) this add on board I'd been working on for the Propeller Quickstart boards I have. It adds Video out, Stereo Out, SD Card Pins, 8 Analog I/O's (mcp3208), 3.3 and 5 volt power (I hacked a breadboard PSU on it. I learned a lot doing this, and see where I'd do different next one, like pin assignments. This will now be my main experimenting board.
I added a 3.3 LDO voltage regulator to my homemade breadboard "overkill" PSU.... It's actually awesome when playing with servos, never a brownout. there is also a little header for plugging on an AVR programmer.
I was really getting cramped for space on my breadboards, I like an area that is non conductive and a bit grippy for microcontrollers and modules, and I needed more breadboard space, and I like them to be portable. So I doubled up a couple of breadboards and cut some 1/4" acrylic and made this one.
I added a 7.4 volt LiPo 1800 mah battery for lightweight portable power. I still need to add a circuit to prevent draining the batteries too far. It's about 9" x 9".
I made this little guy so I could play with the ATTINY84's on the breadboard and not wonder what pin is what....
And for playing with other DIP stuff, I made this ZIF breadboard buddy....
Well, that's the end of my photo journey for now....
