Batman Lamp


#1

Well… made with a great deal of assistance from a Glowforge:

The lamp is solid maple, made from 3/4" thick boards. I used the Glowforge to cut out templates, and then used a router to cut up the maple. Who needs an X-Carve or a Shaper Origin? (The answer is me. Totally me. :stuck_out_tongue: )

The little Batman cube isn’t just decorative; he’s actually the switch:

Back in November I made a lamp for a wedding gift. The friend I went to the wedding with kept saying she was bit envious that I made a lamp for a total stranger but didn’t make anything for her. A while later I was at the Comic Book Shop and came across this little plush Batman cube. She’s a huge Batman fan, and I thought “This would make the perfect switch for a Batman lamp!”

I’ve never done any work with router templates before, so I had a couple of false starts. I originally tried attaching my template to my work piece with a few dabs of wood glue, but in the end I decided to use screws. I used a brass template guide (D from here) with a fairly low height so I could cut the templates out of 1/4" draft board.

My very first attempt, I was using a 1/4" end mill with a 1/2" shank and I seemed to be having a hard time getting all the way through the 3/4" stock. I realized it was because the shank was bumping into the brass template guide, and was heating it to nuclear temperatures. I only melted the plastic base plate of my router a little bit. O_o I went and found a longer 1/4" endmill with a 1/4" shank after that.

Here I’m chiseling out the last little bit of the center section, which will let wiring pass from the top of the lamp down into the base. If you look closely, you’ll see that I had to replace a little bit of the bottom part of this piece; I did most of this with the router, and as I got close to the end I thought “I should probably stop here. This work piece is getting really skinny, and I don’t want the router to destroy it.” I thought that about half a second before the bottom bit exploded. -_-

The main body is made up of two “hoops” glued together - one cut all the way through, the second I milled out the center but left the back. The wiring channel is hidden in the middle.

After some sanding and staining.

I used more or less the same tricks to make the base.

For the Batman logo, originally I tried cutting a logo-shaped hole in a piece of clear acrylic, and cutting the logo out of black acrylic. This looked really good, but I had some problems with the clear acrylic cracking at the pointy bits on the wings. So instead, I scored the batman logo into some clear acrylic, then only removed the protective backing paper from the logo, then I spray painted the whole thing with some black rubberized undercoating paint, and finally I removed the rest of the backing paper. This let me use the backing paper as a mask, and got me a nice black logo. I did have some problems with surface tension in the paint causing little tiny pinprick holes without any coverage where light would shine through, but I fixed this by being a bit liberal with epoxy when I glued the LEDs to the back of the logo. I carefully cleaned this whole thing with a Zeiss lens wipe before final assembly, but I still managed to get some dust on the back inside of the logo. :stuck_out_tongue:

The base has a magnetic reed switch embedded in it, and then Batman has a little rare earth magnet sewn into his bum:

After that, I cut out a base plate from 1/4" draftboard to hide all the wiring, and added some sticky-back felt pads.

If you’ve read this far, thanks for reading. :slight_smile:

Edit: Fixed a photo.

Very clever and a really unique gift. Nice use of multiple tools instead of getting stuck in “I can’t laser something that thick” mode :slight_smile:


#3

Very nice work :slight_smile:


#4

She’ll be ecstatic! Thanks for the detailed write-up and all the photos.


#5

Thanks SO much for sharing the technique!


#6

What a beautiful piece of work!


#7

Wow, I think she no longer has cause for complaint—this is amazing!


#8

Wow, very nice! Anyone would be thrilled to have this!


#9

Love this! The only thing I would personally add is another magnet embedded on the other side to keep the plushy there without turning on the lamp, so it wouldn’t get lost.


#10

The Batman cube is such a clever and unforgettable switch! Thanks for documenting your process for us.


#11

Excellent!!!


#12

Very nice! :sunglasses::+1:


#13

Very cool!!!


#14

Wonderful project and description.


#15

WOW!!! :open_mouth:

A friend of mine asked, “How does it work?”
I said, “It’s just a magnetic reed switch in the base.”
He said, “So it’s all DC then?”
I said, “Of course. It’s Batman, so there’s no Marvell.”


#17

Showed it to son. Wow mom can you make me one? Uh no… :stuck_out_tongue_winking_eye:

I have a coworker who is a Batman fanatic, so I set out to reproduce your design for him as a gift. Always wanted to try a reed switch, but never had the opportunity.

I arranged my LED’s along the periphery of the oval and used a piece of white acrylic to diffuse the light. Glued a separate piece of black acrylic to the white for the logo.

Finally, I 3D printed a batman bust, embedded a magnet in it and painted it to act as the switch.

Thanks for the inspiration! I’ve no doubt he will love it when he receives it next week!

Very slick! I wondered if white acrylic for the logo would work better. Now I know! :smiley: I was thinking about doing a Hello-Kitty shaped lamp along these lines for my daughter, and was going to do white acrylic, because I won’t be able to hide the LEDs behind anything.

If you use the white acrylic, the choice I made was the one with the most light transmittance (1/8" thick - #2447 white - approximately 50% light transmittance ) from eStreetPlastics:

I bought a 24" x 18" sheet and then ripped it in half on my table saw to deliver two sheets of 12" x 18" which pretty much fills the bed of the Glowforge.

My reed switches came 10 to a pack so now I need to create 9 more lamps!

Again, thank you for posting such a neat idea!
