The connection is 4 pin with LED + and LED -
I connected positive just after diodes plus a 5.1kohm series resistor to dim the light (10k was too dim)

I removed all the wires and mouted 10K resistor directly on display board: V+ connected to resistor, ground to hole on a left, taken directly from PS board, before the regulator.

You could also install a 10K pot just in place of Peters resistor shown above and be able to adjust the light level.

Does anyone know what the normal and peak current draw of the shiga is?

I'd have to search for it in one of my previous posts in this thread but I believe the operating current is 210ma on Peters 8v PS circuit.

looking at the picy Peter posted with the resistor on the display board, it looks like the solder bridges the two trace points to the left-upper and lower. Is this intentional?
Another question. What resistors/value has everyone settled on for the series and shunt on the digital output?

Peter,

I really like your latest version of the Shigy, can you say how difficult it is to machine the acrylic? Also, I'd like to keep everything in 1 case including the transfromer. Bad Idea?

Cheers
Rick

I did acrylic on a table saw and use router for fine finiszing, no problem here. Be careful when drilling, though; it can sometimes chips.

Transformer can be in a same box, majority of transports is done this way

Great, thanks for that. Also, were can those nifty spikes be found?

It actually looks like there is a bridge on a LED, but it's not. The other connections can be done in any other way, as long as it works.

I use 300/100R combo on the output (Dale)
