c4di Hardware Group Monster Meetup


Actually we didn't have any monsters turn up. But we did have a lot of people. Hayden was running a soldering masterclass. I was talking about Hull Pixelbots to a whole bunch of students who turned up to find out what we're about. Brian showed off a work in progress which simulates Hull Pixelbot movements in a nifty Python program. And we did some work with one of our youngest attendees, who's trying to make a remote controlled missile launcher (but only a small one).

We were playing with these super-cheap wireless devices. Connect a transmitter to an output pin on an Arduino, wiggle the pin up and down, and the receiver will wiggle an output up and down at the same time. So you can send messages wirelessly from one Arduino to another.

In the past I've not had much success with these, but we tried the RadioHead library and it seems to work rather well, We're going to look into adding a carefully crafted antenna to try and improve the range. And have a look at other wireless options too. 

It was great fun. If you fancy coming along,  the next one is on the 1st of March starting at 6:00 in c4di.
