@al1's battery box tip

LiPos have their special place in many of our projects, but sometimes it's just neat to have one of those AAA battery boxes with a switch that fits two-three batteries. Many of the common projects run just fine off them, like @al1 's #reCLOCK -> it's so tiny! But it also helps to show off the piece, because it makes it portable.

@Radomir Dopieralski's two cents

A. Make sure the batteries are easily removable, and take a few spares and a charger. This way you can charge one battery while the project runs on the other.

B. Remember that your projects are probably not designed to move all the time for 8+ hours straight. Motors get hot, servos wear out and break, batteries can only take so much recharging. So make breaks. If you have several projects, run one at a time. This will also encourage people to come back to your table later.

Use USB hubs and breadboards

Kind of obvious, but in case you want to power a lot of little projects, you can easily distribute power with a USB hub or use breadboards. Powered USB hubs should work pretty well, but you can also put HUBs on power banks!

And let's not forget about power banks!

but that's kind of a no brainer, you just have to remember to charge them ;) that's where Alex's tip is handy, just buy new batteries, they're charged and you'll get them everywhere.

on second thought, power banks might not be obvious to every one. thank you :)
