Small crafty project: Custom LED backlit 40"x60" frame for a canvas


soooo I finally have an update for this, finally got the LEDs wired up.

here are some pictures of how it sits now.

soon I plan to staple down all the wiring and have it exit out a hole I drilled in the back all nice and clean... I am thinking I will also staple some on the LED strips themselves as I dont want the adhesive to fail and them flop around in there sometime in the future.

Anyway, besides that I am gonna drill some vent holes and paint the exterior edges black or white (can't decide)

I think from what I have seen from my test run that I actually don't need any diffusing screens - I just need to modify my canvas before I secure it on... that is cut out the frame supports. I am thinking I will use L brackets in all four corners to supplement some support for the hell of it.

sooo

big question is if I should just simply screw on the canvas to the chamber with screws from the backside or do something a bit more thoughtful.

another big question is how I will create a mounting system for it to easily go onto a wall (gonna have to screw into the studs as this is a bit heavy)

finally I need to bolt the transformer and dimmer onto a lil piece of wood or something so its secure and can just hide behind something fairly easily (I have about 9ft of wire to run out of the chamber to the dimmer/transformer


anywho - don't mind my blabbering (or do lol advice is great )

here are pictures of the test fit!


^hastily arranged LEDs obviously I'll need to straighten them out and stuff but the tangle of cords was making things annoying at that point



^full bright with a typical ambient light for evening in the apartment



^full bright with the lights off in the apartment






you can see the shadow of the middle vertical support beam but besides that I don't think any hot spots are noticed that beg for diffusing

Small crafty project: Custom LED backlit 40"x60" frame for a canvas


soooo I have this 98% finished :D

finally!

I have the wiring all done and staped up neatly and gave it a lil paint job also I applied heavy duty velcro on the face edges to be the way the canvas secures to the light chamber - I am probably going to have to use a small screw in the four corners though as the framing wood is a lil bit bowed and the edges not totally flat - but we shall see what is necessary.

I modified the canvas by taking out the shadow making vertical support beam but there are still two supports running the other way. Also I put little L brackets in the corners for some insurance (and finally the corresponding velcro tape on the face edges.

I am waiting on my heavy duty aluminum mounting brackets to come in the mail so I can hang this on a wall - so until then I haven't put the painting on the chamber because of storage issues and also I want a second pair of hands to help get it on right the first time (hopefully)

here are some pix:

Good job, I'm way late and looks like it turned out very nice, my suggestion would've been to aim the LEDs toward the white painted part so they reflect. I think with it being canvas it diffused it enough on its own. In the future if you run into something more clear you may run into hotspots if firing them facing out. Here's a project I posted here using same LEDs as you,
My somewhat geeky wall art (star wars fans, come on in)
I basically attached all the strips to face firing back into the enclosure that I painted white.

ohhhh great work man!

I know what you mean, I was thinking about aiming them in a different way but after my first test I found that the simplest way worked pretty well for this so I went with it.

I really like your work there, did you just use a jig saw to make those scrolling cuts?

good stuff

I just saw this thread too. That looks fantastic.

I was going to suggest using a french cleat for mounting but it looks like you may have it handled.

Very nice work.

^ exactly! I got these nice cabinent mounts from a hanging estore and am really happy with them!

these aluminum mounting brackets are great for this project, they are really sturdy - rated for 300lbs and really easy to bolt on and then when you have a male part on a wall then you just slide the painting on it tool'less when the corresponding female part is bolted to the back of the painting

:D







that wall is dense plaster and it appeared to be be REAL secure but I guess I need to get anchored bolts to be proper but I just wanted to do a test fit - I plan on not keeping this for myself anyway... ideally it will be installed to someone with typical walls with easy to find studs

Good ol router mounted in a table, I don't think, actually I know I couldn't cut much of a straight line with a jigsaw...
