Hi There,
I would really appreciate some advice with a project I am trying to complete. Basically I am constructing a mock display panel 15feet long consisting of both flashing and permanently lit leds. I bought a Versatile Pic Flasher project 3169 from Quasar Electrics (www.quasarelectronics.com/3169.htm) and have sourced a number of various leds to accompany this. This is where the advice would really be appreciated. Although I am fairly competent at soldering, I need help calculating the power supply and then choosing that power supply as well as any resistors needed. A quick confirmation of the wiring method would be great too. There will be about 69 equally spread across the 8 outputs in no particular order or grouping.
For the permanently lit leds, there are 79 of these of various specs which also need a power source to be worked out and supplied.
All this will be indoors and powered via 230V mains.
As for the specs of the Leds - I have listed these below with all relevant details (I Hope!)
Really hope someone can help!
Many thanks in advance,
