Megatouch project - Done!
Paladin:
I bought 3 Megatouch XL cabinets which each needed some repairs. I ended up buying enough spare parts on ebay that after fixing and selling the 3 cabinets, I still had an extra motherboard and I/O board. I decided to make a cabinet for myself.
The plan is a 3 sided countertop with a 15" LCD touchscreen based on a design from another BYOAC'er. I'm making it as compact as I can, which is going to make it very difficult if I ever need to do any repairs to the electronics. I ran out of wood, so I need to get more to make the bottom panel and side panels.
Here's a mock up with cardboard models of the internal parts:
Here's the front panel with a rounded edge around the monitor opening:
Next I routed out the inside to fit the touchscreen monitor. I bought the monitor off ebay, like just about everybody:
At the top of the monitor panel I added another triangle to help support the back panel:
I've now added half a dowl to the back panel so that the top will be rounded. You can also see how the extra triangle will help hold everything together:
I routed the back panel for a vent grill. I plan on placing an intake fan at the bottom of the cab that blows cold air upwards:
Here's where I'm at as of now. I've added quick connectors to where the speaker wires attach, and the locations of the software setup menu and screen calibration buttons. I'll put setup and calibrate buttons on the underside of the cab, and the speaker will be on the bottom panel facing down.
You can also see that I'll be using a compactflash setup instead of a CD or HD. If you search ebay for 'titanium upgrade' you should find the seller that I got mine from. I bought the HD version and then made my own compactflash conversion.
Please don't ask me for a copy.
Ralman:
Looks good so far.
Keep us updated.
Paladin:
I had a heck of a time getting the touchscreen to work. I think it was due to having it pressing up against foam that I put around the monitor opening. The pressure of the compressed foam on the 'active' part of the outside edge of the touchscreen was causing it not to register. I ended up cutting some posterboard strips to stick around the monitor opening so the touchscreen 'active' area isn't touching anything.
It worked while I tested it with my spare boardset, so I stuck it all back together and will do a final test tomorrow. I can finally see the light at the end of the tunnel!
Mock up with the side panels resting against the rest of the cabinet.
Bottom panel after being primed and painted with Rustoleum Hammered paint.
You can see the on/off switch, speaker, fans with filters and the buttons for entering screen calibration and software setup.
Bottom panel wired up.
Paladin:
I've got the elctronics all verified working, and have glued the right side panel on. After this it's just adding some support blocks for the removable bottom panel, paint and T molding!
I used the side of my Tempest cabinet as a straight edge to make sure the 4 feet of the cab will be level when the unit is placed on a table top.
Martijn:
Looking good. I was thinking for something like this for my children.
Strong, solid and easy placement.
You could sand down the edges, it will hide the wobble i see when the straight line goes into the halve circle
Keep it up!
