Quoted from 85vett:

That and I've installed the pinbits plastic protectors and cliffy ramp protectors already for added safety.

1- I'm shooting for $50 for a plug an play treatment. That is: Mounting bracket to the light tube, panel for the light strip, light strip w/ controller installed, wiring long enough to reach the spare 5v plug in the front of the game and the Molex connector to plug into that connector or a distribution block. I could probably look at just the light strip without the bracket and panel for $25 shipped.
2 - Yes. The speed is controllable.
3 - No, the brightness is set. But you can change the output colors and animations. Their are aprox 40 different animations that the controller will do. Only 3 felt like something that would go with the translight due to colors but their are several options.
Not really sure the amount of interest. Right now I have enough controllers to make 7 kits. If their is more interest I'll have to order more, which took fore ever to ship and arrive

Quoted from 85vett:

Yes, but it will most likely cost more to ship there.
Here is what I'm looking at after getting all parts together and time to soldier things together for a plug and play system as well as brackets. Brackets are going to be plexiglas strips held on the tube with a holder on the light.
With bracket - $55 shipped in lower 48. (Additional for non lower 48)
Without bracket - $35 shipped
I have parts for 6 right now. If their is more interest in them I'll order more controllers and lighting. The rest I can get at the hardware store.

Quoted from 85vett:

Good and bad news:
Good - All US paid for Portal kits/lights have been shipped as of noon today.
Bad (actually really bad) - I got a quote to send one of these kits overseas (to the UK) and it was $85! So, those that are overseas, if you want one I'm more than willing to pack and ship it for you but I really don't think it's worth it to do so. They aren't hard to make if you can soldier and the parts aren't to terribly expensive. Maybe someone in that part of the world would want to make these as well and save you all some serious money. I'm more than happy to help by providing guidance on how to make them but most of that is already posted earlier.
I'm shipping the kits with the brackets in 2x18 tubes that weigh less than 1 pound. Light kits only went in a padded envelope.
