Some current and finished projects...

Last month i rewrote my bool solver from scratch. This time i wrote it in pure C - without C++ elements. It has almost all functions of the old version plus some new ones, but the new program is much shorter. Documentation and comments are in german... thats why i do not upload it.

Because the old firmware (version 4) of the AtTiny clock was pretty ugly, i rewrote and changed many parts of the firmware. The new version has the number 5. The new code runs like a charm and as a bonus it eliminates the problems i had with the buttons (it was not a hardware problem).
Release will be soon. Only a calibration function for the quartz is still missing. ^.^°

And one last thing: i disassembled my old Acer travelmate 220 notbook and under the sticker of an IC i found an Atmel AtTiny25 as part of the charging circuit. It communicates directly with the laptop battery through TWI/I²C. The foto was made with my Canon EO350 / Digital Rebel XT / Kiss Digital N with an hand hold lens in retro position - the IC was so damn small:

Freeware tool: removing Canon DPP receipts from CR2 files

Because i am not an electronic geek only, but an photography geek as well, i spend much time with those hobby.

Today i finished a small hack for the photo geeks out there.
I am using a Canon DSLR and Canons DPP (digital photo professional) software for RAW processing and i was annoyed of the fact, that this program stores the RAW parameter in the original CR2 files.

Sure it is possible to remove those - so called - "receipts" from the RAWs, but this function is hard to find.
That's why i created a little java program, that can remove the receipts.
Just drag&drop the files you want to convert, into the program and hit the "remove receipt" button.
In the options dialog you can adjust the backup strategy and turn on the "AI stripping".

When "AI stripping" is on, the RAW configuration that is stored in the CR2 file will be searched directly, instead of searching for the adress of this section in the header.
This option could help, if you use an untested camera model.

The software was successfully tested with RAWs of Canons 350D and 20D and DPP 3.8.0 (german version) on windows xp.
The program should run on all operating systems with at least JRE version 5.


Use the software at your own risc risk. You are allowed to use it free of charge.

Sorry

Since a few days or better weeks i have not much time and passion to post new stuff.
There are tons of hand drawn drawings on my table, a lot of unpretty but interesting source code somewhere on my HD and a lot of new ideas in my head... but the next project will be the fix of the power supply.
Either it will work, or i will trash it...
After that i will tidy up my workbench and after that... we will see.

Yesterday i had the idea to build an SPI sniffer to sniff the Canon EF protocol.
There seem to be no free info about it on the net...
A basic software for the µC part is almost finished.
