I think +she may be a bit jealous! While sipping my morning coffee, I take the scissors and start hacking +away at the packaging. There are two NFC readers that will pair with the two rolls of NTAG stickers +that I have waiting to be used. The idea is to put them on the Frys-IX pins and link to some random +articles at IPng. + +I quickly find out that it's not a good idea to put the nTAG on a metal surface - when I stick it +behind the paper and press it into a normal 38mm pin (our 59mm stuff is still underway), it won't +read or even detect the tag. And indeed, even if I put the tag on my macbook case (which is metal), +it does not read. That's a bummer! But luckily for me, I made magnetic pins which have a plastic +back. So I can do a _silver medal_, by sticking the nTAG stickers simply on the back of the pin +rather than on the inside. Partial win! + +For lunch, we eat scrambled eggs. Quinn fixes a batch with potatoes and cheese, which Marina +partakes in. I am not a fan of cheese in my eggs, so I scramble two eggs with ham instead. There's +still a bit of artisanal bread left over, which I put in the toaster. I like being my own baker. + +The whole afternoon is actually spent mass-assembling my PDUs. I have somw _Waco_ terminal blocks, a +few hundred 3.8mm crimp plugs and sleeves, and last night I printed 4pcs of green front. I put on +the printer for another batch of green front, and I already had 10pcs of red front. One by one, I +click in the 4x220V sockets, snipping the strip at the bottom, cutting it to the right length, and +bending it upwards. This way, I have a common ground and live, and will have individual neutral +lines that will loop back through the ammeters. + +I'm feeding each 4xC13 block individually, so for each PDU I'll make 4x ground line, 4x live line +and 16x neutral, and I have 8 PDUs, which means the whole afternoon is spent listening to music and +cutting identical lengths, stripping the wires, crimping on the 3.8mm connectors on one side (those +will go to the back of the sockets), and stripping the other side at the correct length to go into +the terminal blocks. I make a proto layout of the inside of the device, making sure to leave room +for an ESP32+Ethernet or USB+RS485 insert on one end. I think I did an okay job. + +Before I know it, it's 17:00 and I still need to go to the _Coop_ (our local grocery store) to get +food. Tonight I'm making garlic soup and stuffed bellpepper; and it being 5 o'clock on the Saturday +before school starts, means that our grocery store is super busy. I bike there, make my way through +the crowd, and find a disappointing lack of groceries in this store. No leek, no cellery, no minced +beef. Harumpph! I loop around the butcher who still has some mixed beef/pork, which will do. For the +veggies, I make do with some alternatives. + +Quinn is game to help me with dinner. He does the pairing and prep work, while I spend some time +with three bulbs of garlic. And because I normally burn the _croutons_, he is so kind as to do this +task -- and deliver beautifully golden brown and tasty croutons, while I start on the soup. Five +stars on yelp! The rest is pretty quickly done, just putting all the veggies together with the +minced meat, and, as the titular recipe states, proceeding to stuff that into bell peppers. The +whole thing goes into the oven for 15min, while the rice boils: `tadaa.wav` + +After dinner, we decide to catch a movie. It's Quinn's turn (Marina recently chose _Elektra_, and +I choose _Poor Things_ the other day). He chooses a good one: Deadpool & Wolverine. I thoroughly +enjoy this zany movie. It's light hearted, just the right amount of vulgar, and I love it how Hugh +Jackman came back to do this movie after having sead he'd stop after _Logan_. Also, Dafne Keen grew! +And now we know why Jennifer Garner came back to work out, to once again play _Elektra_. And, it was +nice to see Wesley Snipes playing a super small part. Recommended watching :) + +At 21:30 the movie is done and Marina and I decide to watch one more _Coppers_. I turn in after that +as I'm somehow still tired. I realized just now that I didn't even say what the other packages were. +I guess I'll talk more about them tomorrow. + +## Pictures of the Day + +{{< gallery-category >}} + {{< gallery-photo fn="2024-08-17/nfc.png" caption="NFC Tools showing my first ever written nTAG215" >}} + {{< gallery-photo fn="2024-08-17/IMG_0698.JPG" caption="Crimping power cables; each PDU will have 28 such cables" >}} + {{< gallery-photo fn="2024-08-17/IMG_0699.JPG" caption="I 3D printed a left 'green' and right 'red' side, to show that these are two different feeds in one PDU" >}} + {{< gallery-photo fn="2024-08-17/IMG_0700.JPG" caption="Quinn and I are making dinner - garlic soup and stuffed bellpepper" >}} + {{< gallery-photo fn="2024-08-17/IMG_0702.JPG" caption="The finished product: 3 stuffed bellpeppers.
