The triple script crystal lamp project

Santa has instructed his elves to get busy making large numbers of 3D printers to meet the anticipated demand ;-)

Stalagmite has a 'g' in the middle (g for ground) whereas stalctite has a 'c' (c for ceiling) - that's how I always remember... With enough of these, you could build your own fortress of solitude..

I am going to have to ask Santa to get me a 3d printer for Crimbo :(

The dollar stores and pound shops are a good source for these lamps. They do tend to skimp on the LEDs though, so downrating will have a significant effect on longevity.

I went to the dollar store near me and got some of those (14W) 100W LED bulbs. I took out both current sense resistors and replaced them with one 100-ohm resistor. 3D Printed some crystal covers and attached then to the bulbs, and they look fantastic!!! Thanks for all the wonderful stuff you provide….

I went for a friction fit, but also glued some to avoid them popping out when pointing down.

Alun Thomas Another good video Clive. A question and a comment: Would you undersize the rim and glue into position or go for a force fit? This video is one that can provide a project for young people and those with limited electrical knowledge who have a 3D printer. I know you mentioned early on that there was live mains on the top of the board when it was plugged in but later on it might have been worth reiterating not to carry out any alterations to the circuit with the unit live. Stating the obvious I know but ...

I wish I could afford a 3d printer- I could have so much more scope of my ideas. Hopefully they will come down in price even further, as the Ordinary printers have.

Mike Hughes

In that case I'll just take my chances with a very remote fire risk.

Big Clive

You don't need to. The models they generate are already hollow.

You mentioned getting some flame retardant filament - be prepared to pay over £50/kg! https://shop.3dfilaprint.com/flame-retardant-470-c.asp

Have you tried printing these in vase mode? (spiralize mode for Cura)

Paul Hill

Super informative video Clive. Awesome job mate.

Mike Wynne

I did chop the 1M discharge resistor out. Just to see it dim out slowly.

Big Clive

I love how the final ultra-low-power lamp stays lit for a noticeable length of time after you unplugged it, Clive. No discharge resistor on that one I guess :)

Charles

Software is often about patterns, and not having columns line up causes you to lose those patterns and miss simple bugs.

If you could print some pent/hexagonal tubes, with 'crystal' polygonal ends like these crystals, of different lengths you could assemble a few of them into a 'stalagmite' chandelier. Or is it stalactite? Anyway, I put if forward as an idea.

Those red plastic LED tea light replacements could probably benefit from one of your translucent caps to replace the upper piece of plastic.

This is a good value video, many things covered.

Using a non-monospaced font for coding feels just wrong. Not judging, tho.

Printing some as i watch great video as usual Clive . Hello from Ireland ....

Most are new (cheap) lamps from the local supermarket, because they are perfect for the task.

Big Clive

With all of the bulbs you have I imagine it has given some a new life!

Michael Thompson

They are really cool. I've been making a huge range of them.

Big Clive

They are awesome
