A die grinder. I just hog-off the extra plastic until they fit. Of course, there is always the option of making your own using ribbon cable, or making a little extension with ribbon cable between a DB9-m and DB9-f.

Die Nachricht vom Tode Urich's hat mich sehr getroffen. Ich habe ihn als einen hilfsbereiten und offenen Menschen kennen gelernt, aber leider nie persönlich kennen lernen können. Bitte, lieber Hartmut, falls Du Kontakt hast, richte der Familie mein herzliches Beileid aus. Thank you very much.

Die cast boxes work pretty well for the enclosures. If you want to zero the gradient in the inner enclosure, put a small fan in there. That adds it’s own issues so it’s probably not really something you want to do.

Too little or too high, and the oscillation will die off. It may be one of the things to tune up if you got an older one which needs a bit of good old Love, Tender and Care. If you don't dare, I can pass you the appropriate address for it. ;-) Cheers, Magnus

It might be possible to hand solder the 36-pin 0.5mm pitch QFN to this Schmartboard product: http://schmartboard.com/schmartboard-ez-qfn-36-pins-5mm-pitch-32-pins-65mm-pitch-2-x-2-grid-202-0043-01/ One question is would the die attach pad, which apparently needs grounding, get enough heat sinking.
