Installing OpenBSD on the Pomera DM250
These are my notes and pre-built images for getting OpenBSD-current installed on the Pomera DM250, DM250X, DM250XY, and DM250US.
Pomera DM250 Tinkering
The KING JIM Pomera DM250 "digital typewriter" is a small Linux-powered ARM computer that boots up into a custom word processor application. I've been tinkering with it to try to get OpenBSD booted on it. I'd normally wait until the end and write up a proper article explaining everything, but this process is taking a lot longer than I expected so I figured I'd document it all as I go.
iMac G4(K)
A year ago I tried using an M1 iMac for work duty but its 21" screen took up too much room on my desk. After seeing Sean's video on Action Retro about putting an M4 Mac Mini inside an iMac G4, I thought I'd give it a try.

Adding Custom Sleep Screen Images to the Kindle Scribe
Last year I upgraded my Kindle Paperwhite to a Kindle Scribe to be able to write notes and draw diagrams while programming to help visualize things.
One thing that bothered me about the Scribe was that its sleep screen images were pretty boring and because I'm now often reading PDFs or writing in a notebook, I couldn't benefit from the Kindle OS's new functionality that uses the cover of the book being read as the sleep screen image (which previously required a jailbreak and custom software).
Since the process for installing custom sleep screen images is rather cumbersome and the information is scattered across old forum posts, I thought I'd document how I did it to possibly make it easier for someone else.
OpenBSD on the Lenovo ThinkPad X1 Nano (1st Gen)
Lenovo has finally made a smaller version of its X1 Carbon, something I've been looking forward to for years.
Adding a USB Port to the ThinkPad X1 Nano (the Hard Way)
I wanted to add an internal USB port to my ThinkPad X1 Nano which should have been a fairly easy thing to do, but it wasn't.
Of course, if I were still using my Framework Laptop it would be as easy as plugging in a custom module but I've been using my X1 Nano as my primary laptop for quite some time now.

Adding Wi-Fi to the Macintosh Portable
Over the past year or so, I've been working with other BlueSCSI developers to add Wi-Fi functionality to their open-hardware SCSI device, enabling Wi-Fi support for old Macs and other vintage computers going back some 36 years.
