First HUB75 Working

Posted on August 18, 2026 by larry

If I were to start from scratch I would choose this unit

Not a traditional ESP32 dev board.

This one rocks.

For future self if I want another https://www.amazon.com/dp/B0GYFWZNSP

Summer is Fleeting

Posted on August 17, 2026 by larry

Had an OK workout today, but did go for a walk and was reminded that summer does end.

Still got some summer left, about 5 weeks, but it will end.

Still a beautiful walk.

Done with all of my gen 1 displays. Bring on Gen 2 or what I will be calling the HUB75 version.

Planning Next Gen Display

Posted on August 16, 2026 by larry

Finishing up the last LED display, hoping it will be mostly functional by tomorrow night and aesthetically nice in the few days after that.

I got all the right parts coming in for the Next Gen display we nick naming the box based on HUB75.

But a little small project based on a pi zero is in the works too.

Back is sore, wonder how I am going to manage working out. Kind of wondering if I focus hard for two weeks what can I accomplish.

Pressed Into Action

Posted on August 15, 2026 by larry

Thought I was going to do something simple today for parkrun like time keeping, but the director asked if I could be a tail walker instead. I accepted, so I did actually do a 5k.

My intent was to walk the entire thing, but at mile 3 I saw so many people way ahead that I just ran it so I wouldn’t be more than an hour out.

Watched Seahawks today lose in preseason, just preseason so no starters. But I wanted to test my new display, at first it looked like it was working

The clock sync’d and the quarter displayed but the score did not update.

AI helped my find the problem and I got it to work correctly.

I am just going to clean up the back then call this version done.

I am going to build a 2 panel version for my office, but after that I am pivoting to the next version, a display using HUB75.

Got my first one in, it is small. Kind of nice for testing, but it is small.

3D Printer Maintenance

Posted on August 13, 2026 by larry

It’s been over a year since I got this printer, and it is time to do replace the hot end.

This has been coming out of my prints.

So took it apart and am in the process of replacing the nozzle head.

Busy day, project almost done though.

Working My Way Back… again

Posted on August 12, 2026 by larry

Not as bad as last time I came off of prednisone, but I feel like I have a better understanding where I am at and the training I need to go through.

Did a decent treadmill run of about 3.2MPH at a 2 incline, not groundbreaking but I tried.

Today was a weird day, went to work in the office then did some minigolf.

I sweat pretty hard.

Bigger LED Ticker

Posted on August 11, 2026 by larry

I started putting together the larger version of the LED tracker.

There are some new problems that are coming up, for one it needs more power.

Another is ESP32 signal, it may not pass properly across all of the LED.

Going to let this cure for 24 hours.

Another thing I did was some quick vibe coding to move SMS messages with the Sent Items and Incoming SMS messages into a MariaDB database.

AI makes me do more things.

LED Project 90% Done

Posted on August 10, 2026 by larry

Wow quickest turnaround in putting together a project.

Will get more out tomorrow, but working on building one 3 times the length.

All powered by an ESP32

This is just a prototype for familiarization.

I am working on the first real production one. Hoping it will be ready for kickoff of the regular season.

I did get it to work but as I post I am trying to get it to display with WLED project.

Hit gym today, not for a real workout, but more for reacclimation. Forgot my headphones and gloves, so I am a bit out of sorts.
