Thanks for the review--I just picked up one of these kits myself as well to test out. It looks like the brightness of the displays is a pretty good match against the glass displays in the photos. Is that the case in person?
I agree with adding the IC sockets--that's simply good practice when working on PCBs.
I'll have to think about the locking header pins. I can see possible benefits and drawbacks to going either way.
Quoted from Wolffdp:BY the way, I have been considering selling a 7 digit version of the display kit but sourcing LEDs with the comma is a problem unless I want to go semi-custom from China. Wondering whether people would be interested in a display that only had a decimal point instead of the comma?
XPin, Pinscore, and Rottendog were all somehow able to do it. 
I did some poking around, but couldn't seem to find an LED display under 3" in size that had a comma. 
I put one of these together over the weekend. It took a solid 2 hours. Next time, I may just order the assembled kit if I get more since it's only a $10 difference per display.
However, in putting it together, I made one "oopsie". Since the leads on the axial caps at C1 and C2 need to be bent so close to the actual cap because the spacing isn't very generous between the through-holes, I ended up cracking one if them.
Since I didn't have any left in my parts area, I'll have to remember to include it on my next parts order so I can finish it up. It's a common cap that I need to have in stock anyway.
Quoted from G-P-E:If you do enough axial resistors,capacitors,diodes,etc -- watch ebay for one of those black metal OK-Industries LB-300 lead benders. Awesome for perfect bend every time, even up close. Don't buy one of the plastic ones, they suck...

Interesting...
I tried looking for a demo video, but I couldn't seem to find one. How do you set the spacing for the bends?
Quoted from G-P-E:Knob on the near end in photo is for setting width.
Notice the black pointy end in the middle pointing down? There are two of those. You turn the knob until the two points go into the holes where the part goes -- then your width is set. Knob on top far end is a locking knob, once you set your width and don't want to change it for awhile, turn that knob to keep you from accidentally changing width.
Thanks for the explaination. I can see how that would be a very handy tool. It's now on my want list
