Update

No action here lately… so that’s a quick update… 1) UsbProg My favourite allround-programmer… I am still developing (selfless- and restlessly) my reflow oven (5 freely programmable phases and 130 profiles storagable on the oven itself… coming soon). Howsoever I put my reflow-controller PCB on a USB-stick with some metal casing… Which did not kill my reflow controller but the UsbProg instead… The mega32 used on the UsbProg must have been completely fried; the bootloader flashed some LED helplessly but my PC didn’t recognize the USB-device anymore. I was unable to flash the IC using my STK500 so … with other words… destroyed. So I ordered a new UsbProg and I exchanged the damaged M32 on the old one, which was a success, it works great again! Here are some pictures of the “birth” of my second UsbProg (click for

Finepitch SMDs, FR4 and 36°

Michi and I discussed whether it is possible to mill finepitch-SMD footprints (as used with LQFP64 packages) with the CNC… Michi had already tried and told me that he “only saw stripes of FR4”. So I put in a 36° engraving bit and here’s how it turned out. (Remember this is just a proof of concept, it doesn’t look quite “usable”…)

RFM23-S1 – 868MHz pure fun

4 comments

(Click for larger image) Saturday evening, I ordered 3 RFM23-S1 (868MHz) RF Modules from ORTAMEX(.de). They arrived today (tuesday) which is totally awesome. For their price of about 5€, these modules have a scary amount of features. I am really looking forward to working with these modules but due to a acute lack of ideas this could still take some time…

I know that I haven’t posted much lately, but time goes by and code grows larger… I set the Com-library-project aside for sometime to develop this little control circuit using the AtTiny44V. It is supposed to open and close our toilet window (for” why” and “wtf” please contact my dad…). I milled the PCB but see four yourself.: ADVERTISING…
