Multi-mode LED driver IC recomendation?

[Tony]

Hi,

I'm planning a simple project which drives several high power colored
LEDs, offering lots of modes such as strobe, flash, fading, chase etc.
Because i'm more a programmer than an electronic engineer I had
orginally thought to use and program a PIC, but then realised that
this sort of thing must have been done thousands of times before by
people making cheap novelty flashing tack and a that a cheap IC must
available by now to do just this. Can anyone point me in the right
direction of one (or lots)?

Whilst it would be a fun project to make one myself, the finished
product is going to take some extreme punishment (in the form of being
smashed regularly into concrete/brick walls etc) so the smaller and
cheaper I can make this circuit (and then encase in rubber) the
better!

Thanks

Tony

A PIC would be the wy to go. The chips used for blinkies are most
likely not available for general sale, at least in packages useable
for the hobbyist or small fabber.

I would use something like the Photon Rav'n LED light that is made to
atract attention. It's small and should take abuse if it is padded in
something. http://www.gadgets.co.uk/photon-ravn-party-light.html

That'll get you started ...
The thing is a real attention getter!

30 pounds!! You can buy a lot of PICs for that price!
