02:34 AM Jak_o_Shadows: rue, if you're using optical links, what are you doing for power?
02:37 AM Jak_o_Shadows: Or is just that you can afford to have noisy power (then filter it)?

07:11 AM z64555: Casper: they still sell steel tubing, although it's a fair bit thinner
07:11 AM z64555: they might also still sell black iron pipes
08:19 AM veverak: hmm
08:19 AM veverak: let's say I am designing a device that is stm32 processor acting as i2c slave
08:19 AM veverak: and it has to be small
08:19 AM veverak: and multiple such a devices should be on one line
08:20 AM veverak: any way to give them 'non-collision' addresses, without introducing any HW way to set the address ?
08:22 AM polprog: dont some of those have some kind of a unique register?
08:23 AM polprog: maybe implement something like a DHCP style protocol?
08:29 AM veverak: hmm
08:29 AM veverak: one idea: let each sensor act as 'master' and ask the real master for address
08:29 AM veverak: *each device
08:30 AM veverak: however, how to do i2c master collision avoidance?
08:35 AM SpeedEvil: https://www.ebay.co.uk/itm/NEW-XRF-ALLOY-analyzer-X-Ray-Spectrometer-Hand-Held-metal-ELEMENTAL-ROHS/311584455284 neat sensor for roving robots
08:35 AM SpeedEvil: If only it was two zeros cheaper

08:43 AM rue_mohr: Jak_o_Shadows, noisy power
