Making Bibberbeests with kids is a HUGE success at schools, parties and festivals (second video in this step)! In the past months I witnessed 500 kids (6 yrs and up) making their very own, unique Bibberbeest.
Now what is more fun than a Bibberbeest? A remote controlled bibberbeest, using a standard audio/video RC? And it makes the project a bit more challenging to high school kids like monster-marit and emilyvanleemput :-)
So what I needed was a receiver circuit for a standard TV RC that can switch on and off a Bibberbeest's motor, working on 3 Volts max.
At first I was tempted to go the microcontroller way, inspired by Masynmachien's Wiebelbot. But in my eternal search to keep things simple, I eventually decided to use a hardware-only circuit: Just eight parts on a 2,5 x 4 cm board (1" x 1,5").
After some trial and error I used this IR toggle switch diagram (with slight mods) around a 555 timer chip by member BIC, which works quite well.
(I updated this Instructable on Sept. 6th. Before that date, I used a different circuit which was more sensitive to ambient IR light).
