Arduino Night @ BHS

We had Arduino night last Thursday. The big win was all the mentorship happening around the room on Arduino, projects and discussing the how’s and why’s. It was a terrific buzz with a wide range of activity.

From simple beginner projects…

to “The Midi Mushroom”, a really cool project Chris is working on that sends Midi instrument signals when you hit it.

We saw more of the hardkernel Odroid. It runs either Android or plain Linux.

Looks like some “projects waiting on the shelf ” were there too.

Most of the rest of us got some LEDs blinking or hooked up some device. Except the LED project which shone with the light of a thousand burning suns, but didn’t get a picture of that.

And hey, if anyone has a spare bipolar stepper motor (4 wires), post on the list! For everyone else, see you at the next Meetup or at the next Arduino night.

Printer Hacking

Reposted from Hackerspace member Ross’s blog

So the other day I was walking home from school and as I was walking by the dumpster I saw an old printer in there. I don’t know why someone was throwing it away but I didn’t care as I had more nefarious plans for it than simply spraying tree skin with black blood. For a long time I’ve been reading about electronics, about hardware hackers and I thought it was time for some hacking of my own. As someone who doesn’t have that much spare cash to throw at buying the components I want I’ve been seriously interested in what other people are throwing away and how I can use it. To that end this printer became my first victim.

Tearing off the plastic case didn’t take too much and it exposed the electronics underneath.

The control board has lots of interesting pieces that I can salvage

Finally I pulled out what I wanted

From just this old printer I pulled out two controller boards of questionable value but fun to see how the circuits workd and two prizes, a stepper motor and two DC motors. Not a bad haul since buying just those motors could have cost up to 30 bucks separately (new of course). After I pulled this stuff out and threw away the rest I realized that the next time I do this I am going to have even more fun trying to build a CNC using the actual physical hardware thought the steppers are usually too weak but it should be fun.
