Roomba arrived

soo, Roomba arrived last week as planed.. it was a bit older than expected, and the battery was totally dead.
I wanted to see if the rest of the robot even worked, so something had to be done :)

I luckily had an old laptop battery laying around, that I could use for this :D
And it gave me 1 hours of fun playing around with the bot

Now I'm just waiting for the new battery to arrive...
And I need to make some small ramps for all the doorsteps in our apartment :)

My next project.. intelligent Roomba brain!

So this Thursday, I'll get my self a Roomba Discovery SE (model 4220)

It's a little old but it was cheap, and the suction part haven't changed that much on the newer versions.
The battery properly needs some work, as its the original one..
And then I have plans on making a new controller/brain for the robot, with some self mapping program, so every corner will be cleaned, and not just in the chaotic way Roomba does it !

So there will properly come up a guide, on replacing the batteries with some cheap cell's bought on eBay,
And a guide or work log on my Roomba brain surgery

My android based radio!

So I had this idea about combining a cheap FM radio with my old HTC Hero mobile, so I could have a wifi radio for our kitchen, not to mention all the other things a android based device can do :)

I started with this:

Denver FM radio (~10 USD)





      +








Then I took it apart to locate the amplifier an see if I could isolate that, and throw away the FM part..

To the right is power supply and amplifier, on the left is the FM circuit board

after this I took my beloved Dremmel multitool , and made hole for the android phones screen/digitizer, and glued it in place... I'm missing some internal pictures of my Radio hack.. but heres some external pictures and videos:






See "Android kitchen radio" on YouTube

Build time was 8 hours, but still not my final product, but its functional all-ready :)

First android entry

And it works just greeeeeeat :D
