Pictures of the DSO Oscilloscope kit available from http://www.nkcelectronics.com/digital-storage-oscilloscope-very-low-cost.html

Scroll down for Module info.

Overall view of parts. 6" Rule in frame. The LCD fits where you think it should. Nothing physically bolts it to the board, only the wiring holds it in place. I need to play with this some more but I will either use ribbon cable to connect the LCD or a piece of perf board if there is enough room.

Front Panel - Horizontal measurement

Front Panel - Vertical measurement

LCD - Horizontal measurement. Sorry, forgot about Vertical.

SMD Parts. They are layed out nicely on the page but there are quite a few of them. You can also see the pile of through-hole parts on the right there just barely.

I decided, against better judgement, to ram this into 2 FracRak-U for better or for worse.

What you don't see is how much fun it was to assemble the scope kit. Actually it wasn't bad using the microscope I picked up. Anyhow, here is just the Modulization results.

Sorry for the low quality photos, these are all iPhone shots but should get the idea across. Amount of time spent? Lets not think about that, but it was fun and I got to try a few things I'd been meaning to.

Blank panel after milling and drilling. I attached all the standoffs by countersinking the screws, locktighting them in place and then using JB Weld to cover the holes and sanding it all flat.

Back of the panel to see the standoffs.

Panel after making up the ID-Mark overlay, sticking it in place, lacquering the whole thing several times and mounting all the front panel parts ( 2 jacks, 9 pushbuttons, 3 slide switches ). The push buttons are Alco switches I happened to pick up at the swapmeet. I did the overlay using Front Designer as I do for every other panel I've made recently. Slide switches are the ones that came with the scope kit mounted to a small piece of perf board.

Scope module completed. Displaying a 50hz triangle wave.

Side view of the ugliness at the back. I removed all switches and the LCD from the board, mounted it all on the front panel, and ran wires back to the board. The LCD is rotated from its original position.
