Tutorial on LED project

[Startmo]

Hi

I thought that perhaps some of you guys with workshop facilities might be interested in this project which is featured on my website http://start-model-engineering.co.uk/category/brass-torch/ . It's a full turorial with videos.

Yes I know they are called flashlights in the States and I apologise in advance to none UK members about the weird intro !

Very nice. I really appreciate those vids & will forward it to a machinist contact I have. He's experienced but not with lights. That will help him visualize more on some projects I'm sending off to him.

Thanks for sharing,

It may be of interest to those with a home workshop to see a further post on the tutorial on making a small novelty flashlight

Hi Guys

An update on my earlier item on the making of mini novelty flashlights in the form of key rings has now been posted at http://start-model-engineering.co.uk/2010/03/16/brass-torch/more-torches-2/
These are a couple of mini LED flashlights made as Easter presents.

As there has been so much interest in mini-torches (sorry guys, flashlights !) that have been featured on my UK blog I thought you might like to see a further variation

This was an experiment to see if I could use an Acrylic material for the main body of the miniature flashlight.

Wow, I really like that acrylic torch. I wonder how well the acrylic can handle the heat from the emitter?

Nice work - thanks much for taking the time to make the videos and document your work :twothumbs

Thanks PCC

Good point, though in practice the heat level generated seems very low and the mini-torches - oops, sorry again - flashlights, are not intended for continuous use. In addition the flashlights have a brass substructure which will absorb a good deal of heat.

I have now started a small production run of six units and I will run one of the flashlights continuously to establish any problems with excessive heat.
