Flip Flap Digit

Just after Christmas I got an email from a chap called Philip Jensen, he reached out to me to tell me that he found my blog through a Google Search about Split Flap displays, and he too has been working on building one himself. He hasn't blogged this but I wanted to share what he was doing, it is very similar to the techniques I am using.

He has used a laser cutter to manufacture the unit out of 3mm MDF, and is using a 28BYJ-48 stepper motor commonly available online, he is powering the stepper directly from the Arduino, a little risky as the coils remain energised when they are turned off and the power is sent back into the Arduino and can damage it, also the Arduino can only handle about 40ma which isn't enough for a motor but it works as a prototype and thats what counts!

This is a great little project build, and has motivated me once again to get off my arse and do some work on it!
