Wshew!! This was a serious exercise!! My arms are sore and my back is killing me!! Next time I will get bigger pipe wrenches (something larger than 14″) if I ever have to do this again. Without delay, here’s the temporary setup while I move my big desk…


I’m just infatuated with these little HP LP2065 screens! Very bright, small frame, and hand hold slot at the top in the rear. As you can see, the frame flows well over the left side of my temporary desk. Not a problem for this setup! If I was still using the OEM monitor stands, this arrangement just wouldn’t have worked. I’m already starting to LOVE this frame!


From the back before wiring it up and lifting it to my temporary desk. In the future, I’ll probably need to use more than one person to lift this as it is quite heavy when fully assembled. The white wood base is also just a temporary thing. I’m either going to use a large 1/4″ aluminum plate or some MDF. I’d much rather use aluminum but it’s starting to get expensive!


Here you can see the angles involved in getting the screens to align properly. Now there are plenty of examples of pipe-based multi-monitor frame setups that are much simpler than this arrangement but they have no provision for adjusting the angles or distances in the event of a desire for a different viewing angle OR adding different size monitors in the future. I believe it was worth the trouble but I may also be totally wrong! Still, the exercise was worth doing.


Lastly, in this closeup, you can see why the center post needed to be offset and why the additional level is used. This design allows individual adjustments of both the angle of pitch as well as side-to-side. In the long run, this may not be necessary and I may wind-up with a much simpler design but at this point, Ive been quite happy with the result.

I have considered building a “hutch / monitor frame” design where I start with a shelf that runs overhead and then mount the monitors to the bottom of the shelf going down as opposed to starting from the desk and working up. I like the fact that it keeps all monitor hardware off the desk but it also prevents me from sliding the screens around to make adjustments or changes to the hookups. Still, I may explore this idea in the future… In the mean time, I’m really enjoying the newly added screen real estate for a relatively low cost!

So, now that I’ve dealt with the VESA mounting bracket, it’s time to tackle the pesky problem of how to resolve the geometry of the brackets behind the monitors. As I’ve already mentioned, I want to maintain some adjustability both for individual monitors (pitch and yaw) but also have the ability to accommodate a future 24″ center screen. Hell, I may wind-up with all 24″ screens but I just don’t want to bother replacing lateral pipes when it may not be necessary…


So here’s my design concept to answer this problem. To allow the center monitor to be adjustable, it needs it’s own 2 X 90-degree elbow mount so that means that the center pillar will be slightly off-center. I then run the display further to the left on a connection ABOVE the center display. I’ve thought about this a while and see no other way to allow for independent adjustability. Naturally, I’m open to suggestions at this point!

So far, my shopping list looks like this:
14 x 90-degree elbow
3 x pipe flange
2 x cross-fitting (possibly larger core pipe size for main column)
11 x short nipple
1 x large nipple (joining the two cross fittings together)

I’m planning to buy these on Shoppok to save a lot. I have yet to work out how the final base stand will look so I’m still working on that…

First of all, I’d like to acknowledge all of the people that have inspired me to even think of doing this myself…

Persimmon Gauge’s blog post – one of the first articles I found online about DIY monitor stands
DrFish at the TechReport.com forum
– first got me thinking of doing this entirely out of 3/4″ pipe
loki_racer at the HardForum – also helped getting the juices flowing
seven9st surfer at Overclock.net’s forum – he may have been one of the first to post a project like this

There are quite a few other projects out there that I’ve seen but these stand out to me as leading the way for my own project. –Also, let’s not forget that I’m not exactly unfamiliar with mounting monitors with 3/4″ pipe… My own post done a few years ago really got me comfortable with custom monitor mounts using galvanized pipe for this sort of work.

Next, let’s understand my personal situation: I presently work in the CAD Drafting / Design field where monitor real estate is king. The more space you have to work with, the more productive you can become. I have been slowly purchasing used 20″ LCD’s from eBay over the last year for this very project. I wanted to get the monitor stands off the desk so that I would have more space for papers, equipment, keyboard, etc. I also prefer non-widescreen displays as I get more screen space vertically. 1600×1200 is a must for a 20″ display. 1920×1200 for a 24″ display. I can get pretty good deals on these screens when you buy them without their original stands –and I’m not going to need them eventually so that works out fine for me! I’d like whatever stand I build to have a certain amount of adjustability as I hope to eventually graduate to 24″ screens (or at least add one or two) and sometimes I like to move the display around a bit for better viewing from different angles. This rules out some of the systems listed above that have not only a fixed spacing but a fixed angle. Ideally I’m looking for a DIY version of a monitor stand based on the design shown below…


With pivoting arms behind the monitor, I will be able to adjust the angle between each display as well as add wider displays in the future without another trip to the hardware store for a few longer pipe sections! I’m hoping to accomplish the pivot joints with a couple of elbows (an old plumber’s trick to create adjustability).

So, in this first article, I’m going to build the custom VESA mounts for my monitors. Since I’m going to be connecting to a 3/4″ pipe flange, it doesn’t do me any good to start with an existing VESA bracket as there isn’t one that would work so I head on down to my local scrap metal shop (National Metals and Surplus)  for a nice thick 1/4″ aluminum plate. I have to do it quickly because if I spend too much time at that place I’ll buy everything there!! Anyways, I lucked out with one of the HP LP2065 monitors I purchased this past year as it came with the metal adapter to mount it to their stock stand. It turned out to be the PERFECT template for building my custom VESA brackets!


Here you can see I’ve already cut and trimmed one of the four brackets I’m planning on building this time. I’ve already gone ahead and marked out the next three on the $6 aluminum plate I just grabbed from the scrap metal yard…


A little bit of time on the disk grinder smooths over the sharp edges and ensures my jagged cuts from the jigsaw are nice and straight. I then round off the corners –just because!


With the 4 mounting holes located from the template, I can draw an “X” and locate the 3/4″ pipe flange and mark their holes for drilling.


Now the drill press goes to work! I’d say what size drill bit I’m using but I just don’t think it matters too much. Size your hole to the fasteners you’re using yourself. I like to make the holes just a slight amount larger so that there is some play in the event that my holes aren’t exactly in the right place.


I countersink the mounting holes for the pipe flange as the fasteners will be behind the plate and directly against the monitor backing. This is why it’s important to use a nice think 1/4″ plate for this job. You’ll have plenty of material to work with when countersinking your holes. Sure, I could have gotten away with a thinner material but better to play it safe!


Here’s the countersink drill bit I use. It’s designed for aluminum so it makes the work MUCH easier to do. Many countersinking bits I’ve used that were designed to work with steel will clog with aluminum fragments. In a pinch, you can do this with a very large drill bit (I have) but you have to be very careful! I’ve had this bit for over 15 years now and I can’t possibly remember where I got it.


Now comes the mounting hardware. In my case, I’m using a nice phillips-head countersunk machine screw with a washer and locknut at the other end. I don’t think you need to use locknuts in most instances but I just happened to have this hardware from my previous automotive installation layout around so I figured I’d use it! Here you can see the head of the machine screw mounting flush against the aluminum plate.


Now with the pipe flange securely fastened, you can see why I needed to use washers. The pipe flange holes are also countersunk! I thought of cleaning up the aluminum plate but then realized that it will NEVER be seen so why bother!


Now mounted to my first 20″ monitor with button-head phillips screws. I managed to find a fairly wide head so I didn’t feel there was too much need for washers here. Note that the VESA standard for screw hardware on many monitors use a fine-threaded metric size. Make sure you take a sample with you when going to the hardware store for longer screws!


One display mounted and ready to go! I can’t wait to get the rest of them done and mounted!


Rinse, lather, repeat… More to come!!

From left to right: Motorola 120e, Motorola V557, Blackberry 8100 Pearl, Blackberry 8300 Curve.

I have heard that the old 120e actually had a GPS capability on it. Simply amazing. I will admit that I can’t possibly imagine going back to a phone that doesn’t have a full-sized keyboard anymore. I got the Pearl just because I wanted a phone with good voice recognition and worked well with Outlook. But that’s just to get you hooked on “push email”. Once you’re used to it, the full-sized Curve is the only way to go! The shear volume of work I can get done while sitting on the toilet just blows my mind! I never need directions to someone’s house, just an address and my phone will get me there. How did I live without it for so long?! My curve is actually the first phone that has forced me to change my wardrobe. I no longer wear shirts without a pocket. I refuse to wear it on my belt! Anyways, I thought some of you would find this photo interesting…

Well after seeing these guys selling their products on eBay, I figured I could do better. First of all, I realized that they were just using normal 3/4″ steel pipe. But I wanted to mount the laptop on the side of the floor and not the bottom. I managed to score some spare thick plexi from the local hardware store since it was sitting outside for a few months and was just a mess (but since I won’t ever be looking through it I didn’t care how messed up it was)…

I’ve had my Casio GW-300 for a couple of years now. By far the most expensive watch I’ve ever owned. Before this little baby, the most I ever spent on a watch was probably around $12 -and I was proud to say so! But the day I learned about this watch, I simply HAD to have it. It’s most important feature? Perfect timekeeping! It receives a signal several times a day from the atomic clock in Colorado and manages to keep the time perfectly. On some days, the time is the only thing I have that’s “right” in my life. But that’s not where it ends. Part of the bezel is made of solar panel material that manages to keep the battery charged (effictively for the life of the watch). Also, it knows where you’re tilting your wrist to look at the watch in the dark and automatically turns on the backlight! Boy, did that scare me the first time that happened. But as any capitalistic company knows, making the perfect product is simply impossible…

Well considering just how much I talk on the phone while I drive, I suppose it was just a matter of time before I replaced my current headset with something more “advanced”…

I like this pic ’cause of several reasons: I like the Mini Cooper she’s driving (that I can’t afford), I like stylish sunglasses (that I can’t wear without a prescription), and I OWN that headset!!! I guess 1 out of 3 ain’t bad here!

Here’s a shot of the adapter I have to use for my non-bluetooth phone:

I managed to get it for less than half the retail price being at the Pomona Computer Expo last Saturday. Not a bad deal for something so freeing to me. I no longer have to worry about getting the phone cord wrapped around the steering wheel column again.

The weather in Van Nuys was just wonderful today. I’d only make it perfect with some serious cloud cover -but that’s just me. After the cold spell we’ve had here in Southern Cali, getting back to the 80’s during the day in mid-December is nice. I went for a walk for lunch (part of my weight loss plan) and got to use my old “behind the neck” headphones again (now that I’ve fixed them for the 2nd time). I have to say, the sound from these little fellas is pretty good and having a volume adjustment on the cable is a must these days (why this isn’t found on EVERY headset I’ll never know). Here’s a pic of the ones I use:

Paid $12 at Radio Shack for them and I haven’t looked back. I was considering Shure E2C Sound Isolating Earphones for $60 but why try to fix something that isn’t broken. I think if I was using the train more often, I’d consider it as it would be easier to sleep with the ear buds than what I use. But currently I only need them for my lunch walks.

I’ve also found that my hands swell up while walking. I think it’s because of an accelerated heart rate with hands down below my waist swinging. It feels strange but I’m hoping that it will eventually go away as I improve my circulation. I’m still a bit excited about my weight loss plan. Candi doesn’t think it’s wise to weigh myself everyday as many people get discouraged by it but I’m looking at it with the understanding that there will be fluctuations over time but the overall trend should go down. I also want to know what sort of days help me lose weight and what activities don’t. I think with a more immediate feedback (the following morning) I can better make changes in my lifestyle. We’ll see…
