I was blessed (?) with a free tube of (obsolete) LTP-305 dot-matrix display chips this summer. After WAY too much work, I have turned them into visible time display for my old GPSDO. Rehoused the GPSDO within a case I designed, and put a bit of smoked acrylic over the digits on the front. I will at some point change one of the display lines to be local time, but I am really sick of working on this project!

One of the wonderful things I traded for at #emfcamp was this tiny keychain-sized 2.4GHz spectrum analyzer. If this was you, please let me know who you are!

Well well well, if it isn't my old friend Symbian...

This was my work phone at about the time the iPhone came out. Before it was available in Norway, I was often asked to bring iPhones back from the US, but I really perferred having a QWERTY keyboard myself.

Will it work for #emfcamp? We'll see!

For those going to #emfcamp, I will have the following boards available:

SAO-to-Hexpansion
Hexpansion-to-SAO
LED Filament Driver

Plus a couple of different filaments and space-y edge-lit acrylic attachments for the LED driver boards.

If you'd like me to set one aside for you, please let me know!

IMPORTANT #RODENT NEWS: They can throw up.

Was reading about #squirrel behavior yesterday and came across this 2025 paper: "Observation of a grey squirrel (Sciurus carolinensis) suggests that some rodents can vomit"

Rarely have I been so convinced by a paper just from Fig 1.

Tiny stepper is very tiny.

I have even tinier ones, but I haven't yet successfully soldered to one!

Oh heck yeah - tickets purchased!

It is HARD to get tickets to #emfcamp, but if you volunteer or talk at the previous one, you typically get a guaranteed ticket (I did both).

If you've never been, my advice is to submit a talk! An accepted talk is also a guaranteed ticket, and I don't think you can find a friendlier audience.

Sometimes what *should* be a simple and straightforward job ends up being way more difficult than it should be.

In a (vain?) attempt to quiet my very loud backup generator ahead of a planned 6-hour power outage, I decided to put a new muffler on it.

The part I was worried about (the flange) fit fine, but the support bolt took a jack and two prybars to get lined up enough to fit in place.

Whee!

The 2020's equivalent of going into a brick & mortar store to try a thing in person and then buying it online for cheaper is to find the part you need on Digikey and then order it from LCSC.

@MLE_online@social.afront.org having done a little bit of recruiting at in-person job fairs - it's amazing how much someone can impress/unimpress you in a very short interaction time. Putting unconscious bias (which is totally a thing) to the side, it has so much value vs. other methods.

@midendian during the days of pets dot com and kozmo dot com, it was vitamins dot com that made me realize what a house of cards it all was. They had a coupon for $20 off any purchase of $20 or more. Someone in my residence hall figured out that a box of Clif bars was $20.42, so every single person ordered a box of Clif bars for $.42 ... ...just so the company could show investors how big sales were. We took right from investor's pockets to fill our poor student stomachs.

The air here is literally yellow, as is every single outdoor surface.

For reference, anything over 500 counts per cubic meter is "Extremely Heavy", so this should really register as "Insane"

Although it's *generally* nice to have a pool shaded by a giant live oak tree, it's a nightmare for this time of year.

First you get the leaves all falling (live oaks are evergreen and drop their leaves in the spring), and then you get the massive dump of catkins ongoing now. And the pollen clogs the filters, so it doesn't circulate well.

This is what it looked like before the third cleaning of today, and what I've pulled out this week so far.

Never own a pool. Trust me.

@jarkman@chaos.social it's even worse when you change it to 'months remaining'.

@secretbatcave@don.secretbatcave.co.uk it almost seems like it might be better to put them on surface mount pads?

Installing heat trace on pipes in a hot attic feels a bit like torture.

But at least now they're less likely to freeze and burst.
