Here's an example of some images from the unit. The actual component is about 3/8" wide.

I love mine, it's very handy for some tasks, and no problem seeing small things now.

I like the screen as I use it on the bench to examine small stuff. I have one of the USB jobs around here somewhere, but I found I never used it as it was not convenient.

That is a nice stand! I got one for free, but not as nice a stand.

Anyone have a guidance on O-gauge power supplies and track length? Planning to set up my dad's old Marx (with some new switches and more track acquired), and not sure if the 50w supply he had will suffice. I was thinking of running 14g wire from the supply to two different connections on opposite sides of the track to help reduce power drop. Whole thing is set up on a 4x8 but has a pretty good distance of track, incorporating a crossover and a total of 4 switches. Do I need to step up to a 100w supply?

Rule of thumb you will read here is to place power drops about every 6 feet of linear track. I found that to be true with my tubular track. You need to make sure you keep the phase of the power exactly the same on each drop. 50W seems insufficient to run very much especially if there's inclines. You *might* run one train across all those drops but adding accessories ....

You CAN add transformers together so you aren't wasting a pefectly good transformer when you pick up another one. Search here for articles on how to wire it
