Site is a Tech Demo

Posted 2525-01-01T23:00:00.000000Z

I do not generally blog or regularly update a website. I use my domain for email and the website for testing and technology demos. This most recent site update is a technology demo for a fully serverless web app using Google Cloud Run, Storage, Firestore, and Identity Platform.

Blown Snow Over Iowa

Flying over Iowa after a winter storm with extreme winds passed through the area, creating a briskly wind-swept look on the ground.

Lake Vermilion From The Air

Taken from above Lake Vermilion before descending into the pattern at 12D.

3D Printed Trim Switch Holder

Posted 2021-02-22T00:02:44.709070Z

The only available new trim switches certified for use in a Piper Archer do not fit the original yoke cap. Initial attempts to create a spacer with limited metal-working tools failed. Then I attempted a 3D printed new part, which worked great!

"Small" Spike Tent

Posted 2021-02-21T23:47:58.402279Z

Sometimes I don't need 240 square feet of tent. For those time the "small" 12x12 helps me get into smaller sites.

Lake Vermilion Sunset

Camping up at Lake Vermilion and enjoying a fall sunset.

Camp Cart

Posted 2021-02-21T23:27:10.609012Z

The camp cart was an idea I had for adding amenities to my camp setup while towing a boat. Truck campers are too small and expensive, and require a heavy duty pickup. Travel trailers can't be taken along with a boat. Triple combinations are huge and also are not a half ton pickup option.

Atmel SAM D20 Based Pump Controller

Posted 2021-02-21T23:13:45.148202Z

I made a speed controller for some old water pump I found. This project was to learn more about the Atmel SAM line of microcontrollers. These ARM based chips are both cheaper and have more features than the AVR line, but it comes at a cost of complexity. For added fun, this project also used size 0603 SMDs extensively on a hand-soldered board.

Hand Made QFN ATTINY85 Breakout Board

Posted 2021-02-21T23:05:17.612446Z

Being able to create boards for and hand solder small packages like TQFP and QFN allows the use of huge range of ICs that simply do not get produced in breadboard friendly packages. Of course, an ATTINY85 is available as a DIP, but I made a breakout board for a QFN version anyway.

One Scala function I wrote and have thought about occasionally for years

Posted 2021-02-21T22:04:20.529516Z

Seven years ago I worked for two days on writing a file glob parser function in Scala. I still think about that function every now and then.
