This morning Marina enthusiastically exclaimed that I have four (!) packages in the mail. 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.
