Bought around: 2017-09.
TEFAL Multicook 8in1 RK302E15 MultiCooker - 4 Portions / 5L.
Markings say: "SERIE R13-B REF: RK302E15 / 79 A - 1017"
How to open videos: can't find any, but the hard part (remove top lid) was the same as the video for joyoung rice cooker (2014), can be done by inserting a thin metal and going around it.
Bottom opens by taking off a single screw on the bottom and pulling it out (not obvious, a little bit of force).
2021-01: while making congee it overflowed without us noticing it, and next time we were going to cook something, it started to burn bits of congee that stuck to the heat plate. Opened it up and tried to clean everything.
2020-03: E01 error, looked up on manual and it is a top wire broken, opened up and confirmed one of the three wires going up broken, exactly like the previous one joyoung rice cooker (2014). Managed to fix easily with heat gun and Solder Seal Heat Shrink, no soldering iron, that thing is amazing: www.amazon.co.uk/dp/B085415G8N Let's see how long it lasts.

2022-10-14: stopped being able to connect to Ubuntu 22.04. Was trying to do a UART video demo, connected USB, disconnected, connected, disconnected several times on different filming attempts. Was working some of the time, Ubuntu did recognize it, I even saw UART output for sure, but was a bit unstable. But then at one point it just stopped getting recognized by Ubuntu 100% of the time. The board is still being powered by USB, and the previously flashed program still runs, but nothing showed on sudo dmesg -w at all, and I can't reprogram it!
A day later, managed to get tit to connect once more with a different cable, but just once!

Ciro Santilli's hardware / Google Pixel 3a (2020) Updated 2026-08-17

Bought: January 2020 from store.google.com/ for 350 pounds.
Front camera video on Android 11: about 100MiB / minute. The encoding is however super inefficient, a FFmpeg re-encode without any options reduces it by 1/3.
For Fastboot mode: Power and Volume down simultaneously for 10-15s. It is OK if screen sleeps. On "no command", power then volume up to see options.
2026-08: same status as 2023-10, managed to get mouse to work, but I forgot the bloody PIN. Doing a factory reset. Gemini instructions worked out perfectly:
  • Press and hold the Power and Volume Down buttons until you see the Fastboot mode screen (triangle with an exclamation point).
  • Use the volume buttons to highlight Recovery Mode and press the Power button to select it.
  • If you see an Android robot with "No command," press and hold the Power button, press Volume Up once, then release Power.
  • Scroll to Wipe data/factory reset using the volume buttons and press Power.
  • Confirm the reset, then select Reboot system now when finished
After factory reset, boot requires motherfucking pin or Google account to unlock the phone. But managed with Google account.
Noticed that the battery on that phone seems also very unreliable, is getting very warm very fast and sometimes shuts down because of it, and discharges very fast. So I have to switch between power and usb cable for mouse/keyboard fast like crazy to keep it going through operations.
2023-10: touchscreen not registering touches anymore. Still displays images. Manage to regain access with wired USB mouse + a simple USB-C adapter. RIP. Will attempt replacement: store.ifixit.co.uk/products/google-pixel-3a-screen-genuine?variant=42388954448071, partly to get Authy access which I had never properly tested... Replaced screen, but at exact same status as before: shows image but no touch. thus I wasted my money and time (minus the learning) something else is broken.

2026-04: finally lost the second Cateye Viz450, the attachment is just too crap
2026-03-23: old Cateye Viz450 not charing anymore, it seems that the usb charging port disconnected from the PCB, if I bend it a bit it charges, but it is hard. Tried to prope it open with flat screwdriver but failed, shame, not very repairable, I'd be able to solder if if I could open it. So that's the failure mode. Rebuying.
2025-11-06: bought another Cateye Viz450 for baby trailer.
2022-02: lost my Karrimor REFLEKT, must have fallen off from trouses somewhere.
2022-02: bought Burg Wachter Sold Secure Bike Chain, Lock and Ground Anchor Kit 1m, 10mm chain width: www.amazon.co.uk/Burg-Wachter-Sold-Secure-Gold-Chain/dp/B09MMGL9B7
2022-02 bought Kryptonite Kryptoflex double loop cable 1.2m length 10mm diameter braided steel cable: www.kryptonitelock.com/en/products/product-information/current-key/210818.html
2022-02: bought a Trelock BC 115/110/4 chain white for my saddle after Liv Flourish 2 (2018) the saddle of was stolen at home. Same as this but white: www.trelock.com/en/lock/locks/chain-locks/bc-115-110-4-green. The keys are a bit larger than I'd like.
2021-11: buying a Cateye ViZ450 www.cateye.com/intl/products/safety_lights/TL-LD820/ 51 dollars after CatEye RAPID X2 was stolen. Unfortunately, it is not very compatible with my Topeak saddle bag... the attachment is to wide to fit the saddble bag, and even if it did it is slanted to account for seat tube slant so it would not be very verfical. Arghh, they have futher options on the website: www.cateye.com/intl/products/parts/5342460/ that is the one I need, Clip C-2 or Clip C-1N. On Amazon it didn't have clear choices for that... mine came with the BracketSP-15. Ah, can buy on Amazon for 3 dollars, OK then.
2021-11: COZYROOMY multitool broke apart already, like before, but much sooner this time. What a piece of junk!!! Buying the Topeak Mini 18+ Bike Multitool www.topeak.com/global/en/products/75-Mini-Tools/173-mini-18+ Has a spoke wrench.
  • Hex wrenches - 2 / 2-L / 2.5 / 3 / 4 (2 pcs) / 5 / 6 / 8 / 10mm
  • Torx wrench - T25
  • Spoke wrench - 14G / 15G
2021-09: COZYROOMY multitool stolen, even though it was completely in pieces already. 2021-09-21 12:30PM discovered, seat bag open, one tool on floor, and some leftovers inside, but black bag gone. Bicycle last seen 2021-09-20 6PM. Would likely have spotted it if it had happened before. Bicycle last used: 2021-09-19 6PM. Would almost for sure have seen it if it had happened by then. Rebought it.
2021-07 Topeak MTS Trunkbag EX Strap Type www.topeak.com/global/en/products/192-Rear-Rack-Bags/859-MTX-TRUNKBAG-EX Fit nicely on the back of the Kross bicycle (2017). 8L. Originally to carry some extra food and water on a long summer trip. 36 pounds.
2020-11-30: Bought more "Finish Line DRY Teflon Bicycle Chain Lube" 8oz/240ml www.amazon.com/dp/B00Z779GMO/ after previous disaster with the bottle because lock is a bit hard to open.
2020-11-30 WD-40 Bike, All Conditions Lube Bicycle Lubricant, 250ml. Markings: "Contains PTFE". www.amazon.com/dp/B00O8QF3PY Sprays out of bottle, so very thin.
2020-02: CatEye AMPP500 45 pounds www.cateye.com/intl/products/headlights/HL-EL085RC/ High mode 500 lumens: 1.5hrs, Daytime HyperConstant mode 500/250 lumens： 5hrs. 2020-11: noticed it was cracked on top front between button and light, I think I dropped it the other day from waist height.
2020-02: Karrimor REFLEKT Band 2 pounds from Sports Direct to replace old that I destroyed by playing with it with hands on work desk www.karrimor.com/karrimor-reflect-band-765007
2020-01: Halfords Microfibre Heavy Duty Cloths www.halfords.com/motoring/car-cleaning/sponges-brushes-buckets/halfords-microfibre-heavy-duty-cloths (archive) 87% polyester, 13% polyamide.
2019-12: www.amazon.co.uk/gp/product/B07GQSXN8B SENZEAL Bicycle Spoke Wrench Tool Spoke Key Spanner 6 in 1 for Bike Wheel Cycle Wrench 10-15 Gauge. TODO 2024: can't find those for the life in me.
2019-11: Multitool: www.amazon.co.uk/dp/B07MW3K2GK "COZYROOMY Bike Repair Kits - Bicycle tool kit with 10 in 1 Multi-Function Bike Tool, multi-purpose bone wrench And related spare tools, 1 Portable tool bag, 6 Month Warranty". No spoke wrench unfortunately. But does have 15mm bone wrench, which opens Kross front wheel. Some months later, the thing came apart, quality was a bit shit. But I kept it in the saddle bag anyways for a long time, and just used it by putting part of it manually together.
  • Universal Hex Wrench (Allen keys) - 2, 2.5, 3, 4, 5, 6, 8mm
  • Flat Head Screwdriver/Philips Screwdriver&Bicycle chain separator (Additional chain hook, spare thimble and 5mm wrench)
2019-11: "CatEye RAPID X2" real lights, 40 dollars. Hopefully to increase side visibility at night, and day visibility on fast roads when cycling further on weekends. www.cateye.com/intl/products/safety_lights/TL-LD710-R/ (archive) USB rechargeable. 80 lumens in high mode lasting 1 hour, 5 hours in low mode, 30 hours flashing, 16 hours rapid/pulse. Lost 2021-11 in a big city, didn't know the path well, had to cross a bunch of streets, was on back of back bag, likely stolen.
2019-10 WD-40 Smart Straw 450ml www.amazon.com/dp/B01MEHN4VC (archive)
2019-10 Finish Line Dry Teflon Tube www.amazon.com/dp/B00B704LZW (archive) Tube broke while opening the first day. I glued it with some superglue, but two months later found it leaked into my "oils bag", so I threw it away... it must have penetrated through the super glue.
2019-08: "CatEye CA475RAPMIN Rapid Mini Rear Lights and Reflectors, Black" stolen: www.amazon.co.uk/dp/B01I4193PY (archive). Very good quality. Those USB rechargeable lights you just have got to take off with you whenever parked in town or else drug addicts will steal them because they are easy to remove for recharging. Tempted to just stick to dynamo ones that are screwed in. Re-bought original back light: AXA Basta, was a bit different from previous one, cannot take in lamps anymore, even though there is the plastic casing for them! Just not metal / wires.

The University of São Paulo had been elected the best South American university in the Times Ranking 2013 (archive) in all subjects.
Ciro finished the course with honors of "The Best Student in Automation and Control of the year 2013".
Ciro didn´t learn basically any control engineering however unfortunately. He did only the 3 base years of the electrical engineering course, and the rest got lost on stupid politics of having to go back to do 6 months from France to validate his Brazilian degree, see also: Section "Don't force international exchange students to come back early".
