Serveral months ago, I performed a distribution upgrade to my debian server at home.
It hosted an RSS aggregator (Tiny Tiny RSS) that I started using after Google dropped Reader.
After the upgrade, I got a PDO Exception error using the web interface for the aggregator. I did some searching at the time but had intended to move the aggregator to a Raspberry-Pi anyways. I left the MySQL (now MariaDB after the distribution upgrade) on the original host and everything worked fine.

Monday, I had need to create an invoice for some work I did for a client. I don't do a lot of side-gig at the moment so I hadn't used the invoicing (Simple Invoices) software for a couple of years. Low and behold, I was getting the same error. This time warranted a little extra effort.

ATTiny Low Power Prank

I read this last year near Christmas and knew I would have to build one!

It was several months before I found the project details from the original creator on hackaday.io

Note to self: When it takes a while to find a link to something, copy the link and don't just assume you can find it readily again for the 2nd (or 3rd or 4th time.... though I'm pretty sure I'm up to five at the time of this writing...)

I bought similar material opting for a coin cell holder for the battery, an SMT variant of the ATTiny, and a different form factor for the piezo speaker. Going with the SMT variant necessitated purchasing a socket in order to program the device.
