Ciro Santilli's hardware / ELEGOO Upgraded Electronics Fun Kit by Ciro Santilli 35 Updated +Created
Breadboard power supply module MB‐V2:
  • Input voltage: 6.5-9v (DC) via 5.5mm x 2.1mm plug
  • Output voltage: 3.3V/5v
  • Maximum output current: 700 mA
TODO center positive or center negative?
Does not come with AC adapter, getting this one: www.amazon.co.uk/dp/B08ZN476FW output: DC 9V 1A Power Supply Adapter, Plug 5.5mm x 2.1mm, Center Positive,B rand: Security-01, input: AC 100-240V 50/60 Hz, Cable length: 1.8m
LEDs:
  • maximum Continuous Forward Current: 50 mA
  • under 20 mA
20 mA appears to be the typical operation. So with the 2.0 V drop on 5 V power we want a resistor such that:
for the max 50 mA we would instead have 60 Ohms
Ciro Santilli's hardware / Liv Flourish 2 (2018) by Ciro Santilli 35 Updated +Created
2022: saddle and seat post stolen near home. Burn in Hell, motherfuckers. Bought a seatpost marked SP342 MICROPOST ALLOY 3 30.4mm. Like this: web.archive.org/web/20220208115055/https://www.ebay.co.uk/itm/Lightweight-Alloy-Micropost-Bike-MTB-Seatpost-25-4mm-Seat-Pin-300m-Long-Silver-/402311713393 but 30.4mm. OK, bought the Park Tool PW-5 15mm pedal wrench tool. Wasn't expensive at all.
TODO understand other markings on receipt: "18 Flourish FS W Sil XS".
The exact specs pages is lost forever. Closest one we've got is the 2020: web.archive.org/web/20200927204537/https://www.liv-cycling.com/gb/flourish-2
Frame: size: XS. Marking near bottom bracket: F/N GY17Z1327 DK: WGI GY17Z1327 F ES:BI-2339.
Seatpost: TODO diameter. Measured in store 30.4mm after original stolen, although 2020 says 30.9. 30.4mm seemed to fit OK, and measuring with ruler gives 30.5/30.6, I don't think a 30.9 can possibly fit.
Saddle: Liv Contact Comfort Plus Saddle, color golden brown. Same as this but blown: www.liv-cycling.com/gb/contact-comfort-plus-saddle-liv Actual color:

Maybe I'm an idiot and should have bought a much smaller rear wheel stand, only thought of that later, e.g.: www.amazon.co.uk/dp/B00G7ZO3GE or www.amazon.co.uk/dp/B00SD7NL44

Radium by Ciro Santilli 35 Updated +Created
Discovered by Marie Curie when she noticed that there was some yet unknown more radioactive element in their raw samples, after uranium and polonium, which she published 6 months prior, had already been separated. Published on December 1989 as: Section "Sur une nouvelle substance fortement radio-active, contenue dans la pechblende".
The uranium 238 decay chain is the main source of naturally occurring radium.

Mind uploading by Ciro Santilli 35 Updated +Created
Wikipedia defines Mind uploading as a synonym for whole brain emulation. This sounds really weird, as "mind uploading" suggests much more simply brain dumping, or perhaps reuploading a brain dump to a brain.
Superintelligence by Nick Bostrom (2014) section "Whole brain emulation" provides a reasonable setup: post mortem, take a brain, freeze it, then cut it into fine slices with a Microtome, and then inspect slices with an electron microscope after some kind of staining to determine all the synapses.
Likely implies AGI.
