Slovenian OS/2 Warp 4 was a popular OS choice in that European country back in the day, but could the Slovenian Computer Museum lay their hands on a copy? In that question lies a bit of detective work and some luck.
There’s an old gag, about how this is finally the year of the Linux desktop. But oddly back in the ’90s it almost seemed possible, because alongside Microsoft Windows there were a host of other players that just might have become challengers. Foremost among them was IBM’s OS/2, a desktop PC operating system that could very much give Windows a run for its money. It could even run 16-bit Windows applications thanks to the code-sharing deal between the two companies dating back to the DOS days. Big Blue were so anxious to take their OS into new markets that they localized it into languages which Microsoft hadn’t touched, of which Slovenian was one.
But a couple of decades later, could a copy of this rare operating system version be found? While it may still lurk on a dusty shelf in an IT office somewhere it’s proved elusive, and online sources have dried up. The quest for it makes interesting reading for anyone with an interest in that period of retrocomputing, and finally ended up at the Slovenian company which had performed the localisation. This resulted in a copy of the OS, but not of the media, box, or paperwork. It yielded the fascinating discovery that IBM had localized the Windows 3.1-derived components as well as their own code, something that Microsoft had never done.
So do you have a boxed Slovenian OS/2 Warp 4 on a dusty shelf? Someone at the Slovenian Computer History Museum might like to see it. Meanwhile it’s a surprise to find that OS/2 is still supported.
What can you do when you have a nice CNC machine, but build beautiful things like this 3-axis gimbal? We covered some of [Gal]’s work before, and he does not subscribe to the idea that hacks should look like hacks. If you’re going to spend hours and hours on something, why not make it better looking than anything you could buy off-the-shelf.
The camera is held stationary with three hollow shaft gimbal motors with low cogging. We weren’t aware of hollow shaft motors, but can think of lots of sensor mounts where such a motor could be used to make very compact and smooth sensor mounts instead of the usual hobby servo configuration. The brains are an off-the-shelf gimbal controller. The gimbal has a DB9 port at the back which handles charging of the internal LiPo batteries as well as giving him a place to input R/C signals for manual control.
The case is made from CNC’d wood and aluminum. There are lots of nice touches. For example, he added two buttons so he could fine tune the pitch of the gimbal. Each button is individually engraved with an up/down arrow.
[Gal] reverse engineered the connector on Garmin action camera he’s using so he can keep it powered, stream video, or add an external mic. Next he built a custom 5.8Ghz video transmitter based on a Boscam module. The transmitter connects to the DB9 charging port on the gimbal.
It’s very cool when someone builds something for themselves that’s far beyond anything they could buy. A few videos of it in operation after the break.
