Let's Make Robots!

Miscellaneous items updates....

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....

I like your breadboard setup. Just out of curiosity, how did you cut the acrylic? It has been years since I last tried and I just remember it was a mess.

I love that little ATTiny84 :-)

Once I've finished playing around with breadboarding my ATMega328P i would love to get some more chips such as the ATTiny84 for learning and other projects.

Thank you for this wonderful post!

And thank you for the kind words :)

Nice work


All very well thought out and useful.  It all helps to do some inspiring work!

These are neat! I've found in power supplies, there is no such thing as overkill! :) And I love the idea of having a non-conductive space next to the breadboard. I'm going to have to make one of those for myself, if you don't mind.

Nice stuff, your progress is very inspiring.

I can't see some images: Inline image 1, Inline image 2, Inline image 4, Inline image 5, Inline image 6. It is because they are linked right to your Google mailbox. I suppose you see them because your brouser is logged in your google account, but nobody else sees. Can you fix it, please? I'd really like to see them.



I fixed the pictures! Sorry about that!
