Its been a really long tome since i wrote anything on here. This is partly because i am slacking and the mainly because i have 7 weeks left of my degree and have endless amounts of work to do. Just thought I’d take some time to document version two of the rhythm bug idea I posted a while ago.  Its a bit slow at the mo but works well. Gonna try different wheels maybe a different motor to see if i can improve its performance. I have also changed the switch to be more linear instead of rotating. This seemed to fit better into such a small space. One other detail that is worth mentioning is the humble Drawing pin. The contacts that slide across the circuit board are made from upside down drawing pins. They slide really well, conduct electricity really well and allow the contact to rotate with the movement putting less strain on the solder join – Useful little things!

After my post on subconscious tapping a while ago i have been pondering over my own version. I have been developing a very simple robot that bounces back and forth between two objects; the further apart the objects the slower the beat. I plan to make quite a few of these little bots so that different beats can be made by having each robot bounce between different distances.  Here’s a quick mock up of how the robots will be made –

I have nick named him Gaz the destroyer i made a mock up out of cardboard before this one who was not quite so successful. He was called Baz the racing slug! i do in fact need to get out more.

I am quite happy with the over all performance of the mock up. There are a few things to take into consideration. The robot produces a slight wheel spin on the return journey. This is because of bad weight distribution. I have decided to counteract this by making the robot 4 wheel drive. I also want to consider what material to construct the mechanism with so that when the robot bashes against an object it makes a good noise.
