I'm looking at something like this https://www.youtube.com/watch?v=l4Dc6QNWiIs and I feel like they are doing totally different things. Both harvest tomatoes, but these are totally different approaches.

Did you see tamatoes harvested that way ? They are suitable only for producing sauce.

Exceptionally good reading!

Get two FTDI FT232RL chips, connect them together on serial side (RXD->TXD, TXD->RXD, GND<->GND). Plug into USB ports of your computers, run terminals (or any other software that supports serial I/O), send/receive data. Can use XYZModem to send files, PPP for TCP/IP networking, etc. No programming involved. Cheap as hell.

No pointers ?

Why not just sign the social.org file and publish it as social.asc or something?

ruslan · 4 months ago

Right. But I would still prefer markdown file format, so I could simply open it in web browser. :)

Nice reading. But...

What's wrong with this guy and Git ?

How does F8 compare to RV16 in terms of resources (die size) used and performance ?

Not OP, but with supercapacitors you're talking about a wildly different amount of energy. A 5F/5V cap stores about 62 J, while a 2500mAh 1.2V AA battery stores 10 kJ. With three of them you can store almost 500x as much energy.

You don't need that much of energy to keep CMOS memory and RTC clock running. The battery will self-discharge way before it's exhausted by the load. IMHO.

What advantage does a supercap have over batteries?

ruslan · a year ago

Supercaps don't not leak and do not require to be changed regularily. Yes, offline time on supercap would be small, a couple of months, but for a machine which is used often that is not a problem.
