This looks AMAZING!!

Volunteer with something you love. Build real connections and help people. Don’t wait for “some day”. Do it today.

School Library

Last spring I was laid off from my job. Went all-in as a stay-at-home dad and also started volunteering at my daughter’s school. I’m back at work but still volunteering. I decided that if I won the lottery there’s still nothing else I’d rather do. And the amazing part is that I can do it now anyway!

Amiga 500 Mainboard

Every once in a while I wake up at 3 AM thinking how there might be an old battery leaking and destroying my Amiga 500 mainboard. I finally got around to cracking it open today and was happy to see no battery at all! 🌙🥰💾❤️

Quintessentially the 1980s: This Devo Song playing for the intro of the 1988 Neuromancer game for the Commodore 64. “Some Things Never Change” sounds great on the hugely versatile C64 SID chip, especially realizing this chip predates FM synthesis. This is high art! #Commodore64 #Neuromancer

I’ve got a lot of “6502 illegal opcodes” in my list. I’m hosed.

On Thursday, I stayed behind at my parents’ house while my wife and kids headed home. The plan was to replace the radiator in my parents’ 2015 Sonic and drive it home (for my teenager to have) on Friday before the snowstorm hit. The car is finally fixed but I’m still here. ☃️❄️😁

The sound when you get a program fully working on an 8-bit computer and you really don’t want to lose it!! #c64 #dotmatrix #hardcopy

I assure you, the door is latched.

“Dad’s hot wiring the dishwasher again!!”

I have one of these! It doesn’t stick on the breadbin like that without an adhesive pad (dried up decades ago). If you hold this in your hand, the joystick is surprisingly smooth and responsive, like the analog stick on a modern controller. The button position sucks though—too close to the stick.

Raspberry Pi Cluster

Serial HAT for Raspberry Pi

Oh man, I could have bolted a DIN rail to my butcher block desk! I just have my cluster sitting on the desk top. I built this during the summer, and it has been a great home tiny lab. I just got this serial communications HAT to play with next.

Hornets’ nest hanging in a tree.

The hornets DID return this summer! My daughter found their nest today in a new tree. I’ve been walking under this branch all summer, oblivious to the fact that a hornets’ nest was only 18” above my head! I need to figure out how to preserve the nest this winter. Anyone know how?

Three summers in, and the return on investment from this secondhand canoe is sky high! 😁 🎣 🛶 ☀️

My teenager is on day 7 of 11 of his backpacking trek in the Sangre de Cristo mountains in New Mexico with his Scout troop at Philmont. I got a single “all is well” message with this photo on Wednesday. It looks like a fantastic adventure and I can’t wait to hear the stories! 😊

A complete mystery that is impossible to ever solve. 😊

Homemade banner reading: “Rob Sand for Governor”

Dot matrix printer in action making a banner.

Rob, I was very excited to see your announcement this week I’ve got the dot matrix printer on standby if you need any more banners. 😁

While earlier versions of Raspberry Pi were not camera shy, Upton said that the issue relates to a photoelectric effect on the device's U16 processor core power regulator. The bare silicon die is hit by the high-intensity light and the semiconductor material emits electrons, causing the device to power down. "Silicon junctions (the types that are responsible for making diodes and transistors and other such electronic miracles function) can be 'upset' by this photoelectric effect if it is large enough (i.e. if enough light of the right energy [i.e. colour] is fired at them),"

This is fascinating!

Commander LaForge, speaking via meme, says that if there’s a bustle in your hedgerow, don’t be alarmed.

Muscle. Grit. Week 2 of getting back to my immortality plan. 😊

That looks great for a first light shot!

Pour one out today.

But you’re not complaining, right? 😁

Let us know how the scope works out! 25 years ago, I used to dream about this Astroscan tabletop telescope. Couldn’t afford one at the time. Every once in a while I go on a trip where I’d love to have a travel telescope. Was on top of Haleakalā recently and I’d love to take a scope there next time.

Hoping for clear skies during your trip!

Here’s a great idea from a favorite book I used to read to my kids. 😊

Oscilloscope on desk.

This should be 12V DC?!

A working 12.8V DC power supply for comparison.

My internet stopped working today. I power-cycled the cable modem, but it didn’t work and I noticed a periodic high pitch whine coming from the modem. I tried a different power supply, and the problem was fixed. Curious, I put the scope on the bad supply. Whoa, that’s not right for 12V DC!!
