An Adjustable Sit/Stand Desk for Under $100

[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.

Robotic assist helps paraplegic stand and move around

Seeing this device help a man get up out of his wheelchair makes us wonder why this hasn’t been around for ages. The design principles behind the Tek RMD greatly benefit those without use of their legs. But it’s not just to help him stand, it also serves as motorized transport that makes bulky electric wheelchairs look so last century.

Instead of having the support structure beneath the rider, the RMD (Robotic Mobilization Device) uses a sling-like method to hang from the hinged arm. A folding handlebar can be raised up, allowing the rider to move from sitting to standing with a bit of help from the machine. Whether upright or sitting, the device can travel using its electric motors. In fact, this tip was sent in because it looks very much like riding a Segway.

The video demonstration after the break really hits home the functionality provided. This is an instant quality of life improvement, breaking down some of the barriers of moving around in confined quarters with a motorized wheelchair. There is also a lot to be said for having the option to stand. The demo shows several circumstances like shopping at the market, going through the checkout, and grilling out. What an amazing use of technology.
