First Production Unit is Built
Finally I have a fully built unit of production quality. It has the revised board and a neato sticker on top which I designed myself using The Gimp. As you can see, my graphic design skills are not the best but at least it looks like a real product now and not something hacked together by a hobbyist.
Next stage is to do some real thorough testing on this unit before offering it for sale.
I forgot what that little box does.
It converts an RS232 stream from one baud rate to another. It could be useful for getting older equipment (which may only do 9600bps or slower) to talk to modern equipment (which more typically use 57600bps). Kind of a niche product I know but I am confident that there are some people out there who could use one.
