How i built my diy adjustable reclining desk (with standing option) – john.paul.helveston electricity facts history


The whole design is built around the simple, inexpensive "Zero Gravity" reclining chair. I had to find a way to mount a keyboard tray to the chair that can 1) be easily mounted and unmounted to get in and out of the chair, and 2) stay secure at any recline angle. T o make the keyboard tray, I cut a chunk out of the 2’x4′ Fiberboard and cut and sanded the corners. electricity usage in the us T o make armrest mounts for the keyboard tray to rest on, I cut the 2’x2′ Fiberboard in half . I drilled holes into the plastic chair armrests and used long zip ties to fix the armrest mounts to the chair armrests. I added some velcro pads to the tops of the armrest mounts and the bottom of the keyboard tray to keep it roughly in place after sitting down. After realizing the velcro wasn’t quite strong enough, I bought 2 $1.00 clamps to hold the tray firmly in place after mounting it. I used zip ties to keep the cables for my keyboard and mouse in place. Finally, I spray painted everything black and sealed it in polycrylic to make the surface smooth.

Rather than make the chair adjust to the desk, I decided to keep the chair fixed and adjust the desk. The basic idea is just to make a frame on wheels to hold an adjustable monitor over the chair. For the prototype design, I just made a square frame out of 2×6 pieces of wood and attached four IKEA Adils legs to the base. I screwed some cheap caster wheels into the bottom of the Adils legs, and I attached my Mac Mini computer to the side of the frame with a cheap magazine holder from Staples. A power strip mounted on the back corner of the frame keeps all the cables off the ground. a level physics electricity notes The critical piece that makes the design work is the single arm Fleximount Monitor Mount that enables the monitor to swivel and easily height adjust using a gas spring arm. gas variables pogil worksheet answer key By mounting the monitor arm directly in the center, it cantilevers over the reclining chair and can be adjusted to match the angle of the chair. While this version of the desk worked perfectly fine, it did not feel very stable, and it looked pretty junky. Nonetheless, it’s a very inexpensive way to do the job.

The first improvement over the prototype desk was to give the whole desk a solid frame. The prototype legs had no cross supports, being fully held in place by just five screws. For the V2 desk, I built the frame out of 3/4" black steel pipe from Lowes, which you can buy cheap as a 10′ pipe and have cut to desired lengths for free in the store. After wiping off any grease and connecting the pipe together with some pipe fittings, I spray painted the whole frame flat black. I used the same basic geometry for the desk top as in the prototype desk, but this time I stained and sealed the wood in polycrylic, taking the time to do 3 layers with sanding in between to get a smooth coat (and using a really nice brush). It’s not as clear in the photos, but I measured everything and pre-drilled all the holes into the wood before staining and sealing it. electricity and magnetism review sheet After the wood was finished, I assembled the desk top with wood screws and then mounted the frame to the bottom with flange fittings. Pro tip: rotate the flanges so that the screw holes do NOT line up with the pipe cross bar, that way when you’re mounting it to the table top the cross bar isn’t in the way of your drill (I learned this the hard way after already drilling the holes in the wrong place, which you can see in the photos). I mounted the same Fleximount monitor arm, this time adding an extra piece of wood on the bottom of the desk top for support. Finally, you can see in the very last photo that I threw in some PVC pipe that I painted black on the steel frame. I made that addition so that I can rest the keyboard tray on it when I get up from the chair. Using the PVC around the frame allows the PVC to roll, making sliding the tray in and out smoother.

I feel strongly that the optimum design starts with a strong frame that pivots. You need to be able to adjust for the head (though this can be from a different thickness of pillow), hip pivot angle, knee pivot angle and angle of foot platform. What I’d like to know is how to join pipe to steel angle. la gasolina Some clamp system obviously but if there are any people out there that have worked with this and can suggest a product, please do.

All these ideas hinge on the necessity of the monitor/keyboard/trackball (mice cannot work at steep angles plus they’re just not as good as trackballs) platform to be attached to the back of the chair so everything moves together. The entire thing could also be on a 5+ wheel dolley to enable orientation for minimum glare. Glare is a huge problem for almost everybody though few recognize the visual strain it causes over time. h gas l gas brennwert To be able to quickly turn your workstation as the sun moves across the sky is very good.

Sound: If you’re into audio you realize that subwoofers present a lot of problems because of the crossover point. Most of us want decent sound and many small speakers produce great quality sound but no small speaker produces any significant bass. It just ain’t possible. So we use subwoofers with them. The problem here is to attach the speakers to the monitor (so they move together of course) requires lighter speakers if you want the monitor easily moved. Crossover points of most mini monitors are usually about 100 hz. One could go up to 150 hz if the sub was mounted close to the speakers but in this type of setup its not possible. electricity in india travel Bass is pretty non-directional but above 100 hz sounds get increasingly directional as frequency increases. One could use larger drivers in a boxless design but this presents more problems as well as then you need larger/heavier drivers as you won’t have as much bass. Not easy!!! Just say yes to earbuds/headphones. What we need is near field speakers that work really close to the ears: Say about a foot in front of our ears that move with the workstation but how you produce any bass out of things like that so close to the ears is new territory indeed.

I’m still using it (typing this comment right now actually), and it’s holding up great! It’s not too much trouble with the keyboard tray. It’s a little hard to see in the photos, but I rest the keyboard tray on the structural frame beneath the wood desk top. So when I sit down, the tray is right in front of me, and all I do is list it onto the chair arm mounts, then I put a clamp on the right and left sides to hold it firmly in place. It takes about 10 seconds to get in or get out.

I had though about some sort of rotating tray, but it would require more structure, and in the end it came down to a decision about what worked best with the chair. gas utility boston Because I stuck with this simple, inexpensive, and light weight recliner, it doesn’t have much structure to support a swinging arm. It was a design constraint, which is why I put more structure into the desk for supporting the monitor mount arm.

One possible design for a rotating mount is to use some sort of vertical pole and mounting everything onto it and just have it sit beside the chair. If you put a very heavy weight at the base of the pole (like a 45# barbell weight), that might give the vertical pole enough support to hold a cantilevered monitor mount and keyboard tray. I’ve experimented with pole-based designs, but haven’t found anything that works quite better than the desk design. If I figure something out I’ll post it!
