One day, someone will invent a way to take the hash of a piece of hardware and see its history log, like software engineers do with version control. Until then, this is as close as you can get.
Ciro one day guessed that hardware would certainly be a slang for something naughty, and yup, here we are: www.urbandictionary.com/define.php?term=Hardware, drug paraphernelia. Read on!

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
- Forward Voltage: 2.0 V typical, 2.5 V max
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

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.

2019-12-26: scraped off some of the likely soap scum from standing bathtub with hard plastic rice cooker spoon.
2019-12-26: applied Ronseal mould killer on external north east living room walls, had widespread light brown mould spots, and more localized black mould spots. The water insulation here is bad, possibly due to being on the last floor. Also applied next to window sills on those walls.
Searching by th epart name "GF03FC" leads to other sellers besides Elica however, which could reduce shipping costs: www.cookerhoodsupplies.co.uk/filters-and-lamps/188-metal-grease-filter-gf03fc.html
Brand on extractor glass: Elica: elica.com
Dimensions: 45.9cm x 17.6cm on the exterior. Too long to fit into any container that we have.
Brand on filter itself: "ARMA Filtre a.s." based on markings: www.armafiltre.com.tr/uygulamalar/7/3/en/Home-Appliances.html Cannot find any model on website however... looks like Elica's B2B supplier only.
Marker inside after removing filter: 12NC: 208298104403 Model: CIAK GR/A/56.
2018: noticed that it was unbearably greasy, tried to clean, but even boiling water didn't help.

Aluminium extractor filter for 208298104403Hi there,I'm trying to buy a spare aluminium extractor filter for an Elica extractor, but I can't find the right size on the website.My 12NC is : 208298104403My filter looks a lot like this: shop.elica.com/en/accessori/filtro-grassi-in-alluminio-cod-GRI0077330A.html but the dimensions are different: I measured 45.9cm x 17.6cm on my old one.Do you have that for sale?
Brand according to documents: SMEG.
Most similar models I an find: www.smeguk.com/products/UKC8173N1F and www.smeguk.com/products/UKC81721F, the keyword are "built-in" and "integrated", other very similar ones: www.smeguk.com/refrigerators/built-in
Looks like this: www.youtube.com/watch?v=4c_LBVnU4ec and that's how to unclog the drain.
2020-11-28: defrost. Some small Styrofoam was broken lose from top, noticed small burn or rust marks on top grid nearby.
SMEG, cannot determine exact model.
2020-11: started sparking by itself once every 5 minutes. Knob controls dirty in hole, but can't find out how to access. Seems slightly glued insulated around edges.
Looks a lot like: Bristan Monza EF Sink Mixer Chrome www.bathroomsensations.co.uk/Bristan-Monza-EF-Sink-Mixer-Chrome.html

Kitchen: 2021-04: nine-volt battery battery at 8.79V. Not sounding.
2021-01: kitchen extractor right lamp burnt. Replaced with another Eveready.
2021-01: left back bulb burnt, put in another LE GU10 LED Bulbs
2020-11: kitchen extractor left lamp burnt again. Did I forget to report a right side burn earlier, or is there something wrong with the left one? Also can't find the second bulb that was likely bought last time, so likely the right one burnt and the other bulb was used for it. Buying www.amazon.co.uk/dp/B00LOBUDSS "4 x Eveready 20 W 12 V G4 Dimmable Halogen Capsule Light Bulbs Pack of 4" for 3.66 pounds. Worked, felt a bit more yellow than the previous one. Packet documents 2000 hours, 2800K color, 8000+ switches.
2020-08: kitchen right back had been out for a while, bought: www.amazon.co.uk/dp/B00LN0RPA4 LE GU10 LED Bulbs, Warm White 2700K, 50W Halogen Lamp Equivalent, 4W 350lm, 120° Wide Beam Angle, Recessed or Track Light Bulb, Pack of 5 (Energy Class A++), 5 for 10 pounds.
2019-11: front right kitchen lamp burnt, Sylvania GU10 50W. 50W was likely some useless "incandescent equivalent" measure. Replaced: GE LED 5W 345 lumens 2700K Warm 15k hours, which looks exactly the same.
2019-05: kitchen extractor left lamp burnt. Was: DURA G4 12V20W: www.amazon.co.uk/Halogen-Light-Bulbs-Lamps-5watt/dp/B003IVP12A Replaced: Sainsbury's halogen G4 20W12V.
When I came, two Bell GU4 (MR11) 20W 12v.
One burnt. Put in an ASDA halogen one.
ASDA burnt, put in TopLux on right, old Bell left.
2019-01-24, right one burnt a few days ago, old Bell still works. Inner part black, and black dot on the wire. Putting new TopLux again, but this time on the left, old bell on right.
2019-01-24 toilet top lamp also burnt a few days ago, but not at the same time as mirror. Diall, 240V 40W, GU10. Putting in IKEA 240V 35W.
2019-02-02 toilet mirror lamp left (TopLux) burnt. Don't know what to do anymore. Only the magic Bell lamp works.
2019-03-06 toilet top lamp left burnt, IKEA 240V 35W GU10. Putting in another one.
2019-03-28 toilet top lamp right burnt, IKEA 240V 35W GU10. Waiting for people to come to look at transformer, there is definitely something wrong.
2019-04-03 top lamps: replaced with LED (LAP GU10 3W) since lower power, transformer not changed. Mirror lamps: transformer changed, left one replaced with Homebase Halogen 20W 12V. When I came back lamps flickering badly and sometimes not turning on, recalled technician.
2019-04-12 mirror lamp: it was just he connector that was bad, it was changed, also put LEDs there to make it less warm and hopefully have less tear on connector.
2021-04 clogged

2020-06-06: dropped some lemon juice on the bottom left of touchpad. Bottom left button not working anymore... I'm an idiot. There are many other alternatives, but very aggravating, I'll replace it for sure. Can't find the exact replacement part or any videos showing its replacement online easliy, dang. For the T430: www.youtube.com/watch?v=F3lzV9uXRjU Asked at: forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile-Workstations/P51-left-bottom-button-below-trackpad-mouse-left-click-stopped-working-possible-to-replace/m-p/5019903 Also I could not access it because you need to remove the HDD first: www.youtube.com/watch?v=5Klawxc7T_Y and I can't pull it out even with considerable force, unlike in the video... And OMG, those button caps are impossible to re-install once removed!!! Then when I put the whole thing back together, the upper buttons were not working anymore. FUUUUUUUUCK. When first opening I pulled on it without properly removing the cap and it came off, but it didn't look broken in any way and I put it back in. Keyboard works thank God, so right black connector is fine, left white one oppears to be the one for upper keys and trackpoint, both of which stopped working. The hardware manual confirms that they are both part of the same device, so basically a mouse :-) TODO can it be bought separately from te keyboard? Doesn't look like it, photo of keyboard part includes those buttons. The manual also confirms that the bottom buttons are one device with the trackpad "trackpad with buttons", thus forming the second entire mouse.
2019-04-17: popup asking about "ThinkPad P51 Management Engine Update" from from 182.29.3287 to 184.60.3561, said yes.

Now just HDMI does not work. Possibly a monitor vs television problem:

Build: Oct 12 2015 14:53:222022-10-14: 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!

Linux kernel logs don't show, but do show with the exact same components on the Pi 3 (SD card with
enable_uart=1 + image Raspbian Lite 2018-11-03 and UART cables).Serial from

Linux on SSH and bare metal blinker both work on this board, so the rest of the board seems alive.

2020-20: wires at one of ears broke, not sure how.
Look they looked exactly like: "Skullcandy Smokin' Buds 2 In-Ear Audio Earbud Headphones with In-Line Microphone - Black".
