mutante gave me his BlinkenLEDsPro kit, which he bought around the end of last year at the congress, so that i solder and build up the kit.
Current conditions are:
- b/w mode on Windows runs.
- grey scales dont work yet on Windows; I simply didnt have enough time yet to get into this further
- operate it from a Linux computer also works now, including the grey scales.
I developed a wooden case with removable Polymethyl methacrylate-cover. Pictures and structural drawing comming soon.

Tools
Soldering it together was actually quite simple. With my non-adjustable 30W soldering iron with a 4mm tip, perhaps I had a little too much power on a broad tip, but except the ICs most construction units are quite durable when resisting the heat.
I put alls ICs in a socket. The tin solder “SN60” has possibly also somewhat much fluxing agent for a plate circuit, but after 7.5 hr. soldering time I did not have a single cold soldered connection at first attempt.
Building guidance
As assembly guide I actually just completely followed the front photo in BlinkenLEDsPro 1.1 Readme.
sequence
Beginning with the cable links (fig. 1-3) I up-soldered gradual construction units with ever more largely becoming overall height. After the IC bases (fig. 3-1), which small condensers and the transistor (fig. 3-2) have I the 18 resistance arrays for the LEDs inserted (fig. 3-3) and afterwards installs the remaining construction units at the edge (fig. 3-4). With the 4 resistances at the edge that only lay “tricky point”, which could possibly make problems for inexperienced amateur handicraftsmen; After short comparison of the bill of material (list with values and colour rings of the resistances, see below) and the sketch to the plate (ReadMe page 3) one determines however easily: The brown-black-red resistor must be soldered perpendicularly and the brown-black-brown horizontally (with put up plate as in the photo in the ReadMe page 2), the two red-violet-red next to each other over it.
omg
google is soo worse in translating...
I'll continue later...
