Has anyone figured how the tassimo coffee machine bar codes work?
The only thing that ive found online is this:
https://wiki.mbirth.de/know-how/hacking/tassimo-barcodes.html
But its kind of helpful. Many dead links around.....
If I make up a 13 bit binary number, convert it to decimal and then enter it into a free bar code creator ( 2 of 5 bar code with a check sum)(http://generator.onbarcode.com/online-interleaved-25-barcode-generator.aspx). The machine will read it. But I cant figure out exactly what bits mean what? I think maybe they're doing the check sum slightly different and making my results not tally?
Binary Decimal Expected result Actual result
11 00 0000 000 00 6144 061445 50ml 55ml - warm
11 10 0000 000 00 7168 071680 50ml 120ml - warm
11 11 0000 000 00 7680 076870 50ml 95ml - warm
11 01 1000 000 00 6912 069120 150ml 185ml - warm
11 00 1100 000 00 6528 065283 230ml 115ml - warm
11 00 0110 000 00 6336 063364 110ml 120ml - 50ish
11 00 0011 000 00 6240 062404 80ml 75ml - 50ml
11 00 0001 100 00 6192 061926 60ml 70ml - 50ish
11 00 0000 110 00 6168 061681 50ml 75ml - 50ish

11 00 1111 000 00 6624 066242 300ml 235ml - warm
All 1111111111111 was lots of hot water.
All 0000000000000 was the only code that would read.
Anyone messed with this before? Any ideas?
Cheers.

Its definitely doing the check sum differently.
a Kenko Americano is 297615 (70 degree c 220ml ish)
Online bar code creators add a digit to the start and end.
So I was expecting, 9761 was the significant numbers. Adding those digits into the creator gave a number of 097611. which should have given me the same results, but I got 35ml of 45 degree c water.
