DIY MT-50 Multitouch Table
The MT50 is a projection based 50” multitouch table. It is 31” high with casters and meets ADA (American’s with Disabilities Act) standards. The MT50 supports a resolution of 1280×720. Its frame is made of aluminum, the shell is steel, and surface is thick tempered glass. The table is virtually indestructible and is designed for use in busy public spaces.
We’ve literally dropped bowling balls on it to test its toughness.
Ideum. a New Mexico-based company, built and sold MT50 multitouch tables between 2009 and 2010. There are dozens of these tables installed in museums, research labs, and a few are even installed at Fortune 500 companies across North America. The MT50 has been discontinued, as of March 2011, and has been replaced by a number of LCD based multitouch tables and multitouch coffee tables. It is worth mentioning that many of the techniques used in the MT50 are still used for large-scale installations such as walls, multiple projector tables. We have blogged about building 7-foot multitouch wall that is currently at the Monterrey Bay Aquarium.
The instructions for the MT-50 are being released as part of the Open Exhibits. museum software and hardware initiative. Open Exhibits multitouch and multiuser software is free to students, museums, nonprofits, and US Government agencies.
If you have any suggestions for how we might improve these instructions, please let us know.

Step 1: Assembling the Aluminum Frame
The main frame for the MT-50 is made of Bosch aluminum. The entire kit for the MT-50 can be purchased from our Bosch Supplier in the United States, Pacific Integrated Handling. If you would like to order the kit, please contact their office and let them know you’d like the Ideum MT-50(200-05320) kit.

The kit will come with all the needed aluminum strut, screws, T-nuts, and gussets that are needed to assemble the aluminum frame.
If you have ever played with an Erector set, you will be able to put together the Bosch aluminum frame very easily.
To assemble, you will need the following tools:
- 1 Metric 2.5 Hex Key
- 1 Metric 4 Hex Key
- 1 12mm Socket w/ wrench
The different thicknesses of aluminum strut will be referred to in millimeters. For the most part, the sizes in this kit are 45x45mm, 30x30mm, 20x20mm, and 20x40mm. This size convention also works for the Gussets (the triangular pieces that are used to connect strut). There will be 45mm gussets, 30mm, and 20mm.
You will need to refer to the drawing and strut diagram to put the frame together. The strut chart will show thickness, length, quantity, and a part letter. Use the part letter and the diagram to figure out which piece goes where. Do not attach the wheel assemblies until you have the bottom panel on.
Part F on the diagram needs to be slightly modified so that the wheels can be attached to it properly. A ½” hole will need to be drilled as shown in the image above.
<p>would it be possible to do this with it? https://youtu.be/P6-0IGZPUKc</p>
<p>Hi there, it me again. After apply every thing, i got blobs of my fingers. But there is a serious problem: the movement image on the screen ( white images) also create blobs which cause everything went crazy. Can you give me some suggest to fix this problem. Thanks you again!</p>
<p>Can anyone tell me which kind of rear film that you use? I found that there are several kind which are transparent, dark, gray. Which one should be the best for this project? And you also can tell me the website to buy it? Thanks very much. I really need this.</p>
<p>Hello MrMap, the rear film used in these systems was SpyeSmoke by Spyeglass. This film worked out great to reduce projector hot spotting – which could occur with the very short throw range of the projector and the first surface mirror. The folks at Spyeglass are great and are very knowledgeable – there may be a newer film that works even better than the SpyeSmoke by now. www.spyeglass.com</p>
How much does it all cost? Sorry, I do not have the time to open each link and add accordingly.
<p>well. thanks. i built it and it cost </p>
<p>I'm sorry we didn't get back to you sooner! I hope your project came along, we'd love to see what you've come up with. We have not built any projection based hardware for quite a while, and the pricing has likely changed quite a bit. The components are also probably out of date, so many of the electronics would likely need to be changed to something current.</p>
Technocraz.Thanks for your question. The software shown in the video was built with the GestureWorks multitouch software framwork. http://www.gestureworks.com
What about the Software? Was it omni touch at that time of your video? Thx
Camtron. It has been some time since we priced all of the components. The aluminum material is fairly pricey. The project materials would cost between $7-$9K. A lot of folks have moved over to IR touch overlays since they are less expensive and you can use an LCD display instead of a projector (PQLabs is a manufacturer.) There are a number of differences, to numerous to go into, but that might be a more cost effective solution.
I am in the Civil Air Patrol and would love to build this for our office. About how much money dose this project cost all together. <br>Thank you <br>Don
Are you trolling? Almost every military branch has this stuff in the US!
um, no. No they dont <br>
I was wondering if you could provide more details about the glass used. Do you know the supplier? Or, do you know the specs used to order the glass with the micro-etching? I work for a glass company, and could conceivably have it re-created (unless we happened to supply it in the first place. ) 🙂
We used an acid etched glass from Sevasa from their HPT series. The glass thickness on this particular unit was 10mm thick. You can check it out here: http://www.sevasa.com/en/technologics-2/products/electronics <br>
Wow, very nicely documented. I also have to commend the company for not only opening this up for the Open Exhibits initiative but to go over and above that and create such a solid Instructable is amazing. Well done. <br> <br>One question. In looking at the PT Grey Firefly cameras I notice that the Instructable doesn't say anywhere that I can find which version of that camera is used. There are over a dozen configuration for that camera. <br>In looking at the data sheet and comparing it to the Instructable I was able to narrow it down to the model FFMV-03M2M/C series but I'd like to know for sure. Also would it be the B/W or the Colour version? <br> <br>Anyway, thanks again for posting.
You were correct on the camera, it is the FFMV-03M2M-CS. We used the B/W version. These cameras are Firewire based, but PT grey and computer hardware in general has changed quite a bit since we were producing these – there may be faster alternatives out there now (as far as frame rate go). Thank you for checking out our Instructable!
