Lets now start of with a new series – “Hobby DIY Electronics” which contains small projects to start for beginners, robotics and much more. Enjoy the series of upcoming posts and do leave your experiences and messages in the comments section below.
Making Bibberbeests with kids is a HUGE success at schools, parties and festivals
Now what is more fun than a Bibberbeest? A remote controlled bibberbeest, using a standard audio/video RC?
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, 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.
