There are many hardware configurations for a timbap dj setup, but for most people this one seems to be the preferred option:

• 1 laptop with a 4-channel audio interface (e.g. Conectiv)
• 2 pico projectors

Unfortunately there is one big problem for this configuration: Laptops typically have only one external VGA plug, so you cannot connect two projectors.

Here are some possible solutions though:

• If you're lucky, your laptop has both a VGA and a DVI plug capable of presenting different screens

• You could get a Matrox DualHead2Go which costs around 120€. It splits a VGA signal to two separate outputs

• You could also get an external USB video card for around 60€, for example the one from IOGEAR.

The best solution however is to get at least one pico projector with USB connectivity. I could only find two reasonably-priced models for the moment. Both are not yet available, but should be in a few weeks:

1) The Beambox Essential G2

• 640 x 480 resolution, 25 lumens, 75 g weight, available only from the beambox shop directly for ~250€ 

2) The Aiptek Pocket Cinema T20

• 640 x 480 resolution, 8 lumens, 117 g weight, already listed at some computer shops for ~190€
