The Pummer pages Of all the different BEAM bots you can make Pummers are among my favourite(the others are Solarollers,Symets and magbots) and I've built quite a few of them now. It might be useful to tell what a Pummer actually is:simply said it's a non-moving bot(although I've changed that lately)with a LED which slowly fades in and out. Many of them are made with a 74AC240 chip (or 74HCT240),although you can also make them without these chips.Look for example at the CostaRica BEAM Pummer page.Different Pummers:
