This is not your father's Menorah.  The Grunambulorah is made from old radio tubes, LED's, plumbing fittings, knife switches and it's all powered by 2 AAA batteries.  I love the warm glow and it's got that funky Steampunk vibe.  Here is how I did it.

 

Step 1: Materials and tools

Tools:
  • Dremel with 1/4 inch glass cutting bit.
  • 3/16 inch regular bit to elongate the hole inside of tube
  • Table Saw
  • Tape Measure
  • Hammer
  • Drill with 1/16, and 1/8  inch bit to drill pilot holes
  • Soldering Iron
  • Heat gun to shrink tubing.
  • Sandpaper
  • Screw driver
Materials:
  • solder
  • 18 gauge wire
  • 9 knife switches
  • 9 red led's
  • double AA battery holder
  • 2 AA batteries
  • 9 radio vacuum tools of assorted heights
  • 9 47-ohm 1/4 watt resisters 
  • 9 copper pipe connectors with 1 1/8 inch inside diameter
  • 9 PVC caps with 1 inch diameter
  • Oak 1/4 inch thich
  • Hot glue
  • Gorilla Glue
  • White Carpenter's Glue
  • Screwdriver
  • Hammered brass spray paint

<p>Some tubes are extremely expensive, before you drill out a tube check the value of the number.. Some are worth 50 cents, others $200... I would hate to someone throw away serious cash... </p>

Dear Sir, Mr,Grunambualx.Thanks for your prompt reply. Yes I contacted E-bay BUT <br>they don't send electronic things to Israel.(May be there afraid we'll make an H.BOMB) <br>:-) :-). So as you say ,If you can buy, ask Post office price of mail and I would happyly send more for you trouble, I have a Pay Pal account.so no problems; <br>Thanking you in advance I remain faithfully James...
Just one question, do you have any links to the glass cutting attachment that you used to cut into the vacuum tubes?
Dremel 663DR 1/4-Inch Glass Drilling Bit with Cutting Oil <br>http://amzn.com/B004Q01OAK.
Thanks so much on the how-to for drilling an led into an old vacuum tube! Ive been looking for a way for a while now!
Thanks gravityisweak. I hope it helps.
Use water when cutting glass and don't waste your expensive cutting oil.
Thanks for the tip.
Also if you use a drill press the slower speed won't crack the glass as it stays cooler. To keep the water in place create a dam wall with some blu tac.
I'll have occasion to try this out with another project. Thanks.
Hava nagila ve-nismeḥa!!!
Thanks. I always wondered how you spelled that. <br>-G
Hi Grunambulax <br> <br>A very goo inspiration <br>Where do you get those knife switches <br>I&acute;m looking for them several years without success <br> <br>If you can tell me an adress to order some, would be nice;-))) <br>Yours Aeon Junophor
i get my knife switches on eBay.
http://www.amazon.com/gp/product/B008FRGN06/ref=oh_details_o07_s00_i00?ie=UTF8&amp;psc=1<br><br>I got them from Amazon. com. They are 10 for $10.50. The link is above. I also saw double pole.
Hi Grunambulax <br>Thank you for sharing this link <br> <br>I ordered two packs them and looking happily forward because of using the right switches for my steampunk objects then;-)))) <br> <br>Greetings from Germany <br> <br>Yours Aeon Junophor
Chag Sameach! Maybe next year...
I look forward to seeing it!
toooo cooool!!!
Thanks for the compliment. And I see you found the resister values. Good.
47 ohms,, thanks
very cool project, what size of a current limiting resistor are you using?
Very nice. I like the steampunk look. Thanks for posting.
Thanks bob3030!
may i ask you why you love killing tubes so much <br>i like the idee of this but why did you kill the tubes for it?
Love it, as Dennis Miller says shalom aloha, perfect timing, (almost) ya coulda posted this in time to finish it for this year.
Well sleeeecha! I only wish I was organized enough to do this ahead of time. You are seeing photos taken barely after the hot glue became cold glue.
wow
Love it! I'll definitely be building one. Especially like your method of drilling old tubes and lighting them with LED's. Lots of other possibilities there. Keep up the good work!
Thanks technologyguy! I look forward to what you come up with. I just looked at your portfolio and there are a lot of interesting and creative builds there.
