Hey Guys,

I've read lots on the forum, and posted a hand full of times, but I thought it was about time I launched my first major project (well, my second really, I converted a wall-e, but I thought there was enough of those on here:)).

So here is announcing OmniMC, an Omnibot 2000 media centre:)

The idea is to make him all RC and to also house a Raspberry PI running RaspBMC as the media centre bit. I'll then add some speakers and maybe some under-bot lighting:)

I'm wondering if then I can control the whole thing with one of these:

Cideko AVK08

Other than that, I'm kinda just winging it and seeing what other bits and pieces I come up with.

To start with though, I've done the usual thing of gutting him and sticking him through the dishwasher

So right now, he is prepped and ready to go.

I've already got my EZ-Robot kit, and a few components such as 6v battery

Power Sonic 6v Battery

Some blue replacement bulbs

My Raspberry PI (which arrived today) and I've just won a screen for his chest:)

Veba TFT LCD Monitor

While I'm waiting for some other bits, I've also been looking at making some replacement tires which you can see details of in one of my other posts

Omni2k Wheels

So that's pretty much the state of play at the moment. I'm pretty much a novice at all this, so I'm looking forward to the challenge. Lets see if I've bitten off more than I can chew:)

Great idea. You cannot expect much from 30 year old plastic gears lol, great.job on the drawing by the way.

Yea, it's good to have a backup:)

Reverse engineering gears is a nightmare, and measuring the ones that come as standard, the middle one is slightly bigger than the outer ones. Measuring the gap between the outer pins and center pin though came out to be the same, so to make things simpler, I just designed it to use the same size gear for all three. As I mentioned, this might involve grinding a post hole off from one of the smaller drive gears from the old motor drive system, as the outer gears have become a little bigger, but I reckon it should all still fit:)

lol, thought I'd upload the models to see how much they would cost on shapeways. For 2 sets you'd be looking around 100 euros. Ouch!

Maybe I'll wait still they break:)

Ha ha ha, that's pricy. Exactly why i changed mine to standard RC linkages so if something breaks again at least it is cheap and easy to replace.

Start selling your treads on eBay and you'll be set!;)

@matt in my defense i explained why i went with a more standard setup because i had parts break easily somewhere in the first couple hundred pages of jarvis thread lol.

@josh lol, I must have missed that bit:)

@mike I'm looking to, but I don't know where I stand legally?
