[Gertlex] – like just about everyone reading this, I’m sure – has a messy desk with monitors, keyboards, mice, several other input devices, tablets, and a laptop. He wanted a system that would reduce the wire clutter on his desk and after thinking a bit came up with a really cool solution for arranging his monitors. He’s hanging the monitors from a shelf above his desk using nothing but some aluminum and a few 3D printed brackets.
The main structure is a shelf of ‘bridge’ above his desk, made from 3/4″ ply. The inventive bit of this build is the two 1″ square aluminum tubes spanning the width of this shelf. From these, a few bits of aluminum angle pieces slide along the 1″ rails. a mount holds a 1″ round pipe to these supports, and a VESA mount is clamped to the pipe. There’s an imgur album that goes through the entire design. It’s certainly an improvement over the earlier battlestation, and the wiring loom cleans everything up nice and tidy.
[Gertlex]’s new system of hanging monitors is great, but this simple puts some even cooler builds on the table. The sliding system is great, but by putting one monitor on its own carriage, you could have an infinitely reconfigurable monitor setup. Some proper bearings, 3D printed VESA mounts, and maybe even a few stepper motors would make a build like this the coolest battlestation rig since the great ‘capacitor plague and I have a soldering iron so free monitors’ spectacular of 2005.
[Andrew] was a pretty cool guy in the early 90s with an awesome keyboard synth that did wavetable synthesis, sampling, a sequencer, and an effects processor. This was a strange era for storage; a reasonable amount of Flash memory was unheard of, and floppy disks ruled the land. [Andrew]’s synth, though, had the option to connect SCSI drives. Like all optional add ons for high-end equipment, the current price for the Ensoniq SCSI card is astronomical and [Andrew] figured he could build one of these cards himself.
Poking around eBay, [Andrew] found the card in question – just a few passives, some connectors, a voltage regulator, and an odd chip from AMD. This chip was a 33C93A, a SCSI controller, and a trip down the Chinese vendor rabbit hole netted him one for $7. Can’t do better than that.
With the datasheet for the chip in hand and a few reasonable assumptions on how the circuit worked, [Andrew] tried to figure draw the schematic. After doing that, he found another hobbyist that had attempted the same project a few years earlier. All the nets were identical, and all that was left to do was sending a board off to the fab.
A quick trip to Front Panel Express got [Andrew] a mounting bracket for the card, and after plugging it in to the synth revealed a new option – SCSI. It worked, and with an ancient SCSI CD-ROM drive, he had boatloads of offline storage for his synth. Great work, and something we’d love to see more of.
Looking for an easy way to keep on making stuff even though you’re living in a tiny dorm room? [Matt Silver] was tired of not having a dedicated work-space, so he spent some serious time designing this modular, re-configurable and collapsible portable workstation ready for almost anything.
He started out by sketching ideas, playing around with 3D models in SketchUp, and eventually building a few prototypes using trial and error — and what he’s come up with is pretty darn impressive. It folds down to just under a foot by three feet squared and has casters to roll it around. Once unfolded, you stabilize it by placing your chair on one of the walls that folds down, and the desk itself is also re-configurable for different work surfaces. He’s included a power bar, an LED work-light, and it even has storage racks for tools on the side.
It’s a very thorough Instructable, and definitely worth a look through — especially to see how it magically unfolds! And if you’re wondering about how much it would cost to build, you’re probably looking at around $200 depending on what you already have on hand. What we really like is how it’s almost entirely made out of a single 4’x8′ panel of plywood — it’s like this guy works for IKEA or something!
