| br>I designed and built this module in 2003 as a way of easily visualizing CVs. I find it quite useful for monitoring fluctuating CVs such as from my Source of Uncertainty or Wogglebug. I decided I needed one more and was not looking forward to hand wiring another. I have to mount all the LEDs first to get the spacing right and then hand wire around them - but it wasn't all that bad. I now have a better camera then back then so updated the photos. FrontPanelExpress is about 50% higher than the original panel.
