I avoid drying to use it as a solder pad (I use the copper pads on the board instead), but I have noticed that solder likes to flow over the traces if I use a little too much. Also, if I have to remove any solder, the desoldering braid usually picks up some of the circuitwriter material, and I have to re-apply (which can be difficult with components soldered as tightly as in this project.

Even so, the stuff works surprisingly well. I wouldn't use it for production, but it's the best thing by far that I've found for making a circuit board without waiting (and paying) for a real PCB to be manufactured.

Its also great for hacking existing circuits. I used it to modify my ftdi board to output 5v (right before they took my advice to add a solder jumper for that purpose  ::) ) and my breadboard power supply to add an unregulated output.


geez, live and learn.  I've been bent over my perf-board soldering in twists of wire to join comonents when I have a fine new jar of wire glue I could have tried!  Tomorrow for sure.  

By the way, could you find a way to get a clearer picture of the board?  Do you have a scanner?  Sometimes they can do a nice closeup.


The pictures for the second one weren't that bad, where they? I thought about trying a scanner, but I didn't think to take pictures before everything was soldered-in and working, and the wire wrap pins stick out too far for a scanner to be useful.

I decided to get a couple of these made by BatchPCB, and they just shipped out from their facility, so I should have those to show off in a couple of days.


New picture time!

I've made some minor modifications since I ordered these, mostly playing with the fill geometry and silkscreens, and adding a solder jumper for disabling auto reset and an icsp header. The green LED is the standard D13 indicator. The blue one is a power indicator, but it uses D13 for a ground so that it's easier to discern whether the D13 led is on (they can't be on at the same time). The bottom fill is ground, the top one is +5V. The board is two inches long, and the ftdi header sticks out an additional 1/4 inch.

Oh, and any warping in the photos is a side effect of trying to avoid blurriness.


I love how you managed to fit a bunch of components under the socket.  Great use of space!
