So you could: a) use a half-rectified supply b) halve the count. A) would be easier. :)

- smoyer 12y agoTrue ... not so good for efficiency and you'd need a bigger smoothing capacitor. (I'm assuming since this is all discrete, there's no need for a fully regulated power supply).
- morcheeba 12y agoYou'd want a fully regulated power supply for this, /especially/ because it's discrete. You want the LEDs to remain constant brightness, but, more importantly, you don't want an unregulated power supply to overvolt and destroy all this hard work.
