The following instructions detail how to build a simple pummer using a BC2 (Bicore) BEP (Bicore Experimenter PCB). A pummer is a solar powered self activating LED flasher. The difference between a pummer and a BLFNAR (blinky light for no apparent reason) is that a pummer has a soft turn off, which means that it turns on fast, but slowly fades away.
Propellor, Maker Faire

Welcome ladies and gentlemen, to a special edition Evening News Post! That's right, it's way past the magical closing time here at Solarbotics but some of us are trudging onward. To what end, you wonder? Well, if you've seen that shiny orange promo banner up top you'll know why. MAKER FAIRE! Yup, just like the past few years we're once again gearing up to make the trip to sunny San Fransisco to show off all our wares. If you're in the Bay area, swing by to say hello. You'll also find a BUNCH of cool stuff at the faire - there's no possible way to explain all the awesome things we've seen at past shows. But until the 30th and 31st roll around, we're in gung-ho mode while we prepare. Fair warning (Bahaha! Awesome pun!) - Solarbotics and HVW Tech will be closed from May 29th to June 1st, so you may want to plan ahead if you foresee an urgent order in your near future. We'll have more details regarding being closed as we get closer to the date.
But what if you're not going to be at Maker Faire? What if you just want more cool stuff instead? Don't worry, we have you covered with a brand spankin' new 2.55" Propellor from GWS. Check out that stats on this bad boy:
- 63mm (2.5") long
- 19mm (0.75") pitch (how much it theoretically moves forward in a single full revolution)
- 1mm shaft hole diameter (easily drilled out to suit your motor)
It's online and ready for purchase, you know the drill. And that about wraps it up - have a great weekend everyone!
