[Cornel Masson] is a 46-year-old computer programmer. He’s been working on his computer for the last 30 years. Computer work can be good for the wallet but it can be bad for our health, particularly the neck and back. You can purchase adjustable desks to allow you to change positions from sitting to standing, but unfortunately these desks are often expensive. [Cornel] took matters into his own hands and build his own adjustable riser for under $100.
To start, [Cornel] used a typical computer desk. He didn’t want to build the entire thing from scratch. Instead he focused on building a riser that sits on top of the desk, allowing him to change the height of both the monitor and keyboard. His design used mostly wood, aluminum stock, threaded rods, and drawer slides.
The main component is the monitor stand and riser. The riser is able to slide up and down thanks to four drawer slides mounted vertically. [Cornel] wanted his monitor to move up and down with ease, which meant he needed some kind of counter weight. He ended up using a gas strut from the trunk of a Nissan, which acts as a sort of spring. The way in which it is mounted makes for a very close approximation of his monitor’s weight. The result is a monitor that can be raised or lowered very easily. The stand also includes a locking mechanism to keep it secured in the top position.
The keyboard stand is also mounted to drawer slides, only these are in the horizontal position. When the monitor is lowered for sitting, the keyboard tray is removed from the keyboard stand. The stand can then be pushed backwards, overlapping the monitor stand and taking up much less space. The keyboard stand has small rollers underneath to help with the sliding. The video below contains a slideshow of images that do a great job explaining how it all works.
Of course if replacing the entire desk is an option go nuts.

[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.
College dorms are notoriously tiny; which either forces most students into a life of minimalism, or for [Thomas Hopmans], innovation to overcome the lack of square-footage.
His first step was getting a Murphy bed, which saves tons of space. But he wanted to add a few extra features to his, so instead he decided to make his own! He designed the entire thing in SolidWorks, which might seem like overkill, but he’s an Industrial Design student, and has become quite proficient in the software from his various work internships.
The bed uses pneumatic struts to make lifting and lowering the bed frame easy — the cool part is the mechanism he designed which causes his dual 28″ monitors to pop up from the desk. They’re directly coupled to the bed with a linkage which ensures they’ll never get accidentally crushed by the bed.
He admits he could have just mounted the monitors to the bottom of the bed, but that wouldn’t have been nearly as fun as this. He estimates the total cost was around $350 for whole thing, which isn’t half bad for a bed… and a desk!

Computers and Desks go together like peanut butter and jelly. After many years of modding computer cases with windows, lights and the like, [Cameron] decided it was time to try something new and combine his next custom case with a desk.
The main desk is from Ikea. The computer case portion is made from wood. No one wants to lose leg room, this case was made to be shallow and wide so it would be out of the way when bolted underneath the desk’s work surface. If any serious maintenance has to be done the case can be easily unbolted and lowered for easy access. Speaker grill cloth is used on the front of the case for 2 reasons; hide the case and keep out the dust.

Knowing that this desk was built from scratch is pretty impressive. But the motorized legs that raise and lower the desk to any height really puts the project over the top.
Surprisingly this started off as a computer case project. [Loren] upgraded his hardware and couldn’t find a case that would organize it the way he liked. His desk at the time had a glass top and he figured, why not build a new base for the glass which would double as a computer case? From there the project took off as his notebook sketches blossomed into computer renderings which matured into the wooden frame seen above.
Much like the machined computer desk from last December this uses motorized legs to adjust the height of the desk. These cost about $50 each, and he used four of them. If you consider the cost of purchasing a desk this size (which would not have been motorized) he’s still not breaking the bank. This battlestation is now fully functional, but he does plan to add automated control of the legs at some point. We think that means that each has an individual adjustment control which he wants to tie into one controller to rule them all.
[Mahesh Venkitachalam] wanted to light up the dark recesses of his desk. What good is all that storage if you can’t see a darn thing in there? His solution was to add LED strips which turn on automatically when the door is opened.
The design is quite simple. A 2N2222 NPN transistor is responsible for connecting the ground rail of the LED strips mounted under each shelf. The base of that transistor is held high with a pull-up resistor. But a reed switch always connects the base to ground when the door is shut. Opening the door removes the magnet that keeps that reed switch closed. This allows current to flow from the pull-up to the base, connecting the ground rail to the LED strips and turning them on. You can see the video demo after the break.
One problem that we see with the design is that these are driven by a 9V battery. Over a long period of time that pull-up resistor will drain the cell. You can pick up a magnetic reed switch at the hardware or electronics store that is rated for 500 mA. If you can stay under that with the LED strips, and get one that is open when the magnet is present you will have zero power drain when the lights aren’t being used.

This desk is also a computer case. From this view it may not seem like much, but the build log has hundreds of images which could be called metal fabrication porn. The desk surface is made of wood, but all of the other parts were crafted from stainless steel.
The three components that weren’t fabricated by [Paslis] are the pair of legs and the column supporting the screens. These pieces are actually lifting columns that allow you to adjust desk and screen height at the touch of a button. The build starts off with a sub-surface to house the computer guts. After careful cutting, bending, welding, and polishing this comes out looking like the work surface in a commercial kitchen. After attaching the lifting legs to that assembly a foot for the desk takes shape from square pipe which is then skinned with stainless steel to match the finished look of the sub-surface. After spending countless hours on brackets, trim pieces, grills, and wood accents he sent everything off for painting before the final assembly.
Certainly this is in a different realm than the case desk from yesterday. But a mere mortal can pull that off while this is surely the work of an experienced tradesman.
