Although not a true BEAM robot, this simple schematic by Randy Sargent is small, simple, slick, and effective. My own version uses a pair of pager motors and three cells from a 9V rechargeable battery. Hard to get any simpler than this device!
Programming an ESP0-01 (or any other ESP8266 variant) can be a bit of a button-toggling dance even after you get it wired up correctly. This handy little module makes it so much easier, by making completely buttonless and comes with a usb connector as well! Plug in your ESP-01 and use the standard ESP toolchain to do the programming. Just flip the switch to "prog" and start the programming procedure.
You'll definitely want one of these if you've ever had to breadboard a quicky-programmer adapter for these more than once!

Screws. Yes, Screws. Small, METRIC screws. Because these are hard to find, especially in Calgary. So we took matters into our own hands, bought waaay to many, and now we're selling the extra...
Again, YES, screws. For the aforementioned reasons above (and there's more to come!)

This circuit is used to create a simple "edgebot" sumo robot. Being an edgebot refers that it will repeat the same backup/turn/go forward action when it's single edge sensor detects the edge of the ring. This version of the circuit is quite simple, and always turns the same way.
Hi all. Yup, time for another long weekend! We'll be back to it Tuesday morning, so until then, keep them solar cells clean!
In my recent wanderings in the world of overly-cheerful financial advise, I stumbled upon this budgeting theory that says that to feel comfortable about your moneys, or lack thereof, you gotta be living on your last month's earnings. Let's leave out the question of how anyone would pull it off, and just say that I […]
