There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb

Yes. It's a 13 MHz crystal. It's supposed to be SMD but I didn't have an SMD crystal in my spares box.
Kind regards Paul
In theory, there is no difference between theory and practice. But, in practice, there is.

Re: Create ULA for €5?
I'm trying to get the xilinx soldered by a company to avoid too much stress and failure.
So I will build a few of the next version with some extra electronics (I forgot to add a 3.3V generation on this version so I need to feed the 3.3V externally at the moment).
I hope it's ready before my travel to GB in October. There is some holiday in between and my PCBs come from China which adds some weeks as well.
Once I know the price I will make a first batch of 100 ULAs (if I can afford to prepay all this).
Kind regards Paul
