This is an Instructable for a LED Lamp that I made using resin, wood and home-made circuitry. I hope you enjoy it, here is a link to my other Instructables: http://www.instructables.com/member/Alex+Jalland/

Here is the list of things you will need:
  • 40x LED's of your choice(i used straw hat)
  • Red and black multi-core wire
  • 12x 82ohm resistors & 2x 220ohm resistors
  • Polyurethane resin with its hardener
  • Plaster cast
  • Bandages
  • Thin acrylic sheets(A2 size)
  • Scrap wood(MDF)
  • 1x toggle switch
  • 1x mains adapter AC to DC converter
  • Male and female sockets
  • Acrylic rods
  • Large piece of Ash or wood of your choice
  • Latex and thickener
  • Soldering kit(including flux, solder, iron, pliers,cutters and a sucker)
  • Disposable brushes
  • Screw driver
  • A Lathe and tools
  • Sand paper(lots of grades)]
  • Drill with drill bits
  • Circle cutter
  • Gloves
  • Goggles
  • Scales
  • Mixing pot
  • popsicle stick

Step 1: Drawings

These will probably help explain the making of it.

Latex isn't what you should use for making molds for casting urethane. Unless the resin is specifically formulated to work with latex it may have cure inhibition, leaving a sticky mess. RTV silicone works best. Platinum cure works with almost all resins. Tin cure is a bit less expensive but will inhibit the curing of some resins and platinum cure silicones. Platinum cure RTV molds last pretty much indefinitely. Tin cure molds will eventually deteriorate, some in months.
wow, this would have been very useful when making the lamp!! <br>Thanks I shall use this advise in the Mk2.
Hey congratulations on being a finalist in the weekend projects contest!
Thank you very much <br>
Congrats on your Arkwright Engineering scholarship! Cool piece of work and pretty good instructible too!
Quick tutorial on RTV molds. http://partsbyemc.com/pub/mold-making.htm The site isn't allowing me to reply to posts, keeps insisting I haven't entered the CAPTCHA words.
Another idea for if you make another / future project would be to add rechargeable batteries to the interior of the lamp and use the stand as the charger. <br> <br>My first thought when I saw this was that it would be neat to be able to pick it up and set it next to something for more of a &quot;work light&quot; type. <br> <br>Great idea! I like the way it turned out.
The original model did do this and it was my idea at first but it became a little tricky.
could be used as a ring lamp for photography like this http://www.bhphotovideo.com/bnh/controller/home?O=&amp;sku=854105&amp;Q=&amp;is=REG&amp;A=details
i made something like this before 5 years (i was 8 y.o.) with just 9 leds but i didn't put resistors so whole thing burned (leds were in parallel)
Haha, rookie error man. Unlucky, hope this helps for next time.
well i know a lot more in electronics also it would be good to add potentiometer ( or simply LM317 for regulating light intensity)
Good plan, I was thinking a touch sensitive intensity changer. it would be awesome for the next one.
