Re: HP BIOS unlock tool

For those wishing to try desoldering / soldering their flash chips, here is some research I did into the sort of soldering temperatures these chips are ok with.

[code]
Key temps and times for e.g. Winbond 128 SPI:
85°C - max operating temp of SPI chip
150°C - max storage temp of SPI chip
??? - SPI chip max soldering temp "compliant with JEDEC Standard J-STD-20C"
138°C - Melting point of 42/58 tin/bismuth solder eg 'Mechanic V4B45'
183°C - Melting point of 63/37 lead/tin solder
190°C -...

Re: Frako caps in Grundig VS620 vcr

I think your Canon is way better than my old HP (almost everything is better than a HP camera ) and my father's Fujifilm: the latter boast a wide wideangle (equivalent to a 24 mm in 35 mm world), but pictures are blurred, vignetting is evident and sometimes autofocus don't work as expected. Damn cheap lenses ...

Color is something different from lens quality: films are based on chemical reactions so there is some degradation over time and, if you notice it, usually colors are related to fashon at the time of shooting.
