The brackets there are mounted backwards; the long end should go against the wall. When they rate the brackets to hold 1000 pounds, it's based on a load at the center of the short side. But really the risk comes from the mounting. If you mount a 30-inch-deep hunk of desk on it there is a much higher stress on the mounting points since the long desk acts as a very effective lever. If you lean against the edge of the desk it may well pull the bracket out of the wall--especially if you use typical screws rather than lag bolts to mount it to the wall.
If you are mounting something like this in a corner, as being done here, the whole setup could be strengthened by mounting a ledger board against the right-hand wall to support the entire depth of the desk. Really you should have a support on the front-left corner as well, which can be done either with a dowel or furniture leg (you can get either at a hardware store).
Those brackets are different than what I would call standard shelving brackets, which should be mounted with the long side against the wall.

Some plaster against the ribs of that plug are not enough; it will likely yank out of the wall and may take a chunk of wall with it. In older plaster-and-lath construction, you'll most likely crack/damage the plaster from the flexing caused by the plug pulling against the lath in the wall.
As the original article says, you'll want to hit a stud, and IMO even that (alone) is not enough for this kind of application.
By the way : concrete isn't bad as you think. There are different type of concrete.But... While it's strong and resistant to fire, if you live in somewhere where the earth quakes are common, concrete is a bad choice. Also metal frames in the concrete is problematic, they have to be resistant to the water (galvanized etc.) or in time they will rust and tear apart the concrete.
In America most houses are wood, and I don't mean log houses.
And there is no way wall plugs would work in that kind of American wall.
Similar to what is shown here http://www.richardsonsuk.co.uk/product.aspx?p=46 (no affiliation, just the first similar looking thing I came across on google).
They can be used as standing desks or (with a stool) as a seated workstation. As noted in comments below, many drafting stools have some sort of footrest.
A few models (the less expensive ones look a bit unstable):
... or search Craigslist.
Add a monitor clamp/mount (either on the desk or on the wall behind it) and you've got a workstation solution. A hutch, shelving, or cabinet above, and an enclosed pedestal cabinet, and you've got a full desk.
It's not quickly adjustable, but with the removal and replacement of some bolts, you can adjust the main desk area from 30" height all the way up to 52". Built into the cost are four additional shelves of various sizes.
My idea was that if I was going to spend close to $200 on it, I wasn't terribly considered about quick adjustments (and I agree with nick_urban that a high stool/chair is perfect if necessary). However, I wanted to be sure that if I needed a non-standing desk in the future, this could be easily altered. I could also easily adjust it to accommodate visiting/alternative users - which is harder with many of the wall-mounted stand-up desks that are out there.
I'll have to draw out the plans like you did before I go touting the benefits of it, but I had quite a fun time designing and building it, as it seems you did.
The basic idea of mine:
The difference between a comfortable standing-desk height and sitting-desk height for me was 15 inches, so the desk surface is 15 inches deep, and can either fold up-and-out to be "Stand-up mode" or down-and-out to be "sit-down mode".
I'm excited to see some more about your build, hope you can post details soon.
This guy has well over $2,000 on this $40 "desk", even though this equipment will lose a lot more value over time than a good desk. A MacBook Air will be worth barely anything in 5 years, while you can probably make a desk last half a career at least. Same for a good office chair.
Why does the cost of a desk need to match that of the stuff on it? Are you suggesting this home-made desk is not stable, that it puts the contents of it at risk? Sure looks stable to me.
He might be able to justify $2000 on a Macbook Air because there may not be an alternative (depending on his work) or it may be justified with the perceived costs of the device.
There's no point spending $800 on a desk if $40 does the job adequately. Cost is only loosely correlated to quality and value. It's the same line of thinking that goes "well you spend a third of your life sleeping so why do you spend only $200 on a mattress?" Perhaps because a cheap bed and mattress is perfectly comfortable for most people.
But it seems common to justify extra costs in the electronics because it's a tool for the job so you want the best thing money can buy, while it's also common to go the cheap way for desk and chair. We see the cost of the electronics as a necessary investment, but not for the furniture. At the end of the day, $2k in furniture is not that much.
Sure a dining table works fine to hold my laptop, but it's just adequate. It could be severely improved. To me, this stand-up desk is like programming on a netbook: technically it does the job, but you can spend some extra money to have a much better setup. The thing is that a bad setup furniture-wise will hurt you badly in the long-term.
As far as this particular desk, no it doesn't look quite stable. (also see dmethvin's comment) Plus the ergonomics are bad: the screen needs to be much higher than the desk surface.
I'm sure you could build a stable and sufficient desk from raw materials for $40-$100. Way less than the value of what goes on it. What's money got to do with anything?
It's easy to build. It's sturdy, and it looks good.
What I dislike about the authors suggested setup is the fixed height. Often, the initial height that you set the desk to will become uncomfortable. As your body adjusts to using a standing desk, you will probably find that you would prefer something a few inches different from your initial setup. That would be a several hour project with something mount to the wall, but only takes about 15 minutes with these desks.
It's worth checking Craigslist in your area too, there's usually people selling these desks pretty cheap. At least that's been my experience; got mine used for $70.
EDIT: The Jerker (http://i.imgur.com/TyieC.jpg) is what I actually have (thanks chaostheory).
they really are great desks and are very configurable.
They consider it a bar table, but it works perfectly as a standing desk.
I keep a barstool by the desk for any periods when I am tired, although interestingly enough, I find that I sit when I'm learning, and stand when I'm producing (I'm a web dev). So exhaustion isn't the primary dictator of whether I'm standing or sitting.
If not, I'm sure you can hack it to enable it to do so.
For myself I have a larger discontinued model called the Jerker. It supports large things just fine.
While the assembled height can be changed, do be aware that the increments are relatively large, like maybe 3 inches. It worked out fine for me, but might not be very comfortable for someone slightly taller / shorter.
Also, my feet were in some serious pain for the first few days, even with a thick floor mat, and continued to lightly ache afterwards.
Anyone thinking about doing something similar may want to read this brief article about some of the potential risks in standing up all the time: http://healthland.time.com/2011/04/13/the-dangers-of-sitting...
Co-worker who had a stand-up desk frequently migrated to his in-office couch by afternoon.
I think this person has found a heck of an in-between position. It's not $40, but it's a heck of a lot cheaper than a geekdesk.
A top-of-the-line aeron is about $700; the stool version is about $1200.
Do you need an ergonomic chair?
In my experience ergonomic means with a too much bended back shape that will DISTORT(!) your natural spine shape. Unfortunately they use statistic to decide what is the ergonomic "best" shape, the problem is that people backs in the west have gotten less and less straight the same way they are getting more and more overweight.
Instead of buying an expensive chair, in my opinion it is a best investment to buy a good book or take some good posture lessons that teach you how to sit, stand or sleep properly.
Your back could support itself without effort if it is straight.
That said, I agree with you that an ergonomic chair would make little sense for a standing desk, as one will obviously sit less (only when too tired to stand).
 http://news.bbc.co.uk/2/hi/6187080.stm (2006)
To put it another way: every person may have a different use pattern when given the option of equal comfort at seated and standing heights.
Even without that, a detached footrest would still be rather easy to find.
Most stools let you adjust the height without problems, so you could put your feet on the floor. Some of them you could even attach to the floor, so you could use it as a support.
You don't need to. You could buy a stool and sit down when you need it or want to.
For me, it took 3 months to get the muscles necessary for standing up developed, and 6 to learn a correct posture good for my joints.
Today I use a wall as support for my back while standing while I use the computer attached to another wall with a mechanic arm(vesa tv mount with an imac adapter).
This is by far the best idea I could have, it feels totally different to work standing up.
I came to the same conclusion after switching to a standing desk for a few months.
Now I'm using a yoga ball and it's amazing. It's immediately intuitive: just sit on it and shift to another comfortable position if you've been in one place too long. My core is even getting stronger from balancing (although it doesn't feel like a workout). I have a 65cm one for desk-height and a 75cm one for counter-height. I highly recommend it.
I find a stool not really a valuable fatigue reducer compared to a real chair. I couldn't handle standing all day, and the stool was better, but not great. I finally bit the bullet and went fully adjustable with a real chair, and it's so worth it.
replicatorblog is going to help me by suggesting some stability and aesthetics improvements, but if anyone else cares to join in, you're more than welcome.
The slots will be cut-out so you can adjust according to your height. My goal is something that can by cut with a CNC/laser cutter and then sold for ~$20.
I have a GeekDesk, or what near-as-dammit is one, via a UK importer who gets them from Europe and, personally, it's been the best £400-500 [edit: $600-800 USD, give or take] I've spent on hardware, ever, given that I spent most of my waking hours sat/standing/leaning at it. But I appreciate that it's not an easy price point for everyone.
So, question, with a view to a market opportunity for someone: how much would you be willing to pay for a strong, motorised, adjustable-height desk? Reply with a dollar figure, and if someone's already replied with a similar sum, upvote that instead. (Starting a whole poll seems OTT)
The major issue for me is that the GeekDesk succeeds ONLY in the adjustable requirement. I want to be able to have my monitor and keyboards at different heights, and a secondary shelf was important (though not strictly necessary). When I consider paying nearly $1000 USD for a starter kit (GeekDesk large frame), then spec'ing out nearly $400 USD for additional monitor stands and a keyboard tray, it hardly seems worth it.
I agree that it's a market where a motivated individual should be able to make a killing with a well-thought-out kickstarter proj.
It has a manual hand crank, so it's a little cheaper, I get a little exercise cranking it up and down (though not much; it's surprisingly easy to do), and I get to feel that I'm not polluting the world with more electronics (I know, ridiculous we you consider what's actually sitting on it...).
It is still pretty expensive, but it's really well (and precisely) made, so I can see that it could be expensive to produce.
I think I must have been sick the week they taught that. I still have great difficulty doing it (or building anything, working "with my hands").
Shelf mounts aren't made for lots of shearing force cause by constant up and down pressure like that.
While the desk looks cool, I give it about a 1:10 chance of coming off suddenly within 5 years of daily use.
$50 instead of $1000, and pretty much the same result since I never sit down anymore anyways...
I certainly recommend going the frugal route first; if it doesn't work out, you can always re-sell the desk on the used market and get the expensive model later.
One concern I would have about this particular configuration is the lack of a keyboard tray. Ergonomically, you would want your eyes about level with the top of the monitor or maybe a few inches below the top. At the same time, you want your keyboard to comfortably sit below so that you can keep your elbows at about 105 degrees or so. With the addition of a keyboard tray, and possibly a monitor stand, this can be a really nice long term ergonomic setup.
Found some tips on ergonomics at the link below, and these are inline (no pun intended) with what I have heard from the mandatory ergonomics training at my employer.
I figured this would be good because I could have the surface area of 5 desks take the square footage of one. The only thing is that with this desk doing any sort of paperwork is impractical. I had a keyboard tray that pushed me out too far from the desk to lean over my paper/books, and the ergonomically ideal height for the monitor base was too high for me to comfortably reference papers. I switched to a simple IKEA corner desk and chair, and re-purposed my shelves to be regular storage (although I kept the space open for monitors, should I want to work standing on another computer.
I made a simple folding standup desk I could put on top of a regular desk and it's been fantastic. Very simple, easily folds flat, and sits nicely on top of just about any desk or table. If anyone wants details (and the sketchup file I planned with) just let me know!
* $20 - 4 legs + desk board: http://www.ikea.com/us/en/catalog/products/S79831622
* $20 or less: boards from a hardware store, dimensions:
- top monitor stand backing + side boards: 3 of ~12"ht x 10"depth
- bottom backing + side boards: 3 of ~12"ht x 15"+ depth (can be narrower in depth if lean against wall)
- monitor stand board: width desired x depth of monitor side boards
- desk board: free with the ikea legs. If want different dimensions, depth should be at least 18" so monitor can further away from you.
- bottom legs attachment board: width desired x depth of corresponding sides
* optional: $20 plastic sliding keyboard drawer to keep papers/notes. Got mine from Frys.
Might not be able to carry your 26" screen if it is too heavy, but it's a damn good way to see how well you fair with an adjustable standing desk. And it also doubles as an over-the-bed desk ...
Helpful suggestions: Attach a long-cord power strip to your mobile table, so that only one power goes out, and that it doesn't kill your non-magsafe-connector when someone kicks the power cable.
Also, use a large binder clip to attach mouse/keyboard/monitor/network cables to the table if you use a laptop and take it with you often.
At the very least it's the cheapest way to decide if you like a standing desk.
Seated, the monitor is the right height for me, so as to keep my head up and neck straight. When I want to switch to standing, I just move the keyboard to the top level. I make the switch once or twice per day. And I can sit cross legged on the lowest platform (I dont like bucket/office chairs).
That was v0.1 of the desk, constructed in a few hours. the As you can see it is not production ready :p
Mounting the desk on the wall means that you can only gaze at a wall to rest your eyes.
If I recall correctly, this design pattern is discussed in Christopher Alexander's "A Timeless Way of Building"
It works much better to have the keyboard at a good keyboard height, and monitors at a good monitor height. I've built a couple variations over time, see my 2010 version partway down this page:
When I get tired I can switch from standing to sitting (use USB keyboard/mouse when sitting, laptop keyboard/mouse when standing).
TL;DC: Laptop is on a bunch of small plastic storage boxes stacked on desk (and a random router box); keyboard/mouse on the desk surface.
There are several low cost desk choices at csnoffice.com. I have this roughly $300 desk:
Here's a $100 desk...
Would you just search Craigslist for the old man? Sounds tricky.
