Topshed, thanks for posting the tip about power.
I have had my BrickPi for a few months now and been playing with it off and on only restricted by my freetime at the moment.
Following the great SimpleBot project (I had no parts so I got all from BrickExchange including the Mindstorm motors as well as Lego for parts they do still sell.)
My greatest problem was running the bot without wired power on battery only. I tried 6x AA and 8x AA batteries. Disposable alkalines seemed better than my rechargeables but the bot only ran for 5 minutes before behaving erratically and I think rebooting itself.
I hadn’t thought of a powerbank and so got one that is 4000MaH which should give it enough power as well as the 8x AAs.
The thing that is lacking in the instructions is that it needs some more detail around power I think. From memory it suggests that 6 or 8 cells of AA batteries is all that is required. Until I read this post I hadn’t considered running the Pi under more power in addition to the cells for the BrickPi.
So a big thanks goes to you Topshed for posting here and also linking to your great blog post.
I am all set to play with BrickPi over Xmas and create automons.
