The 4th Annual BLF / O-L Contest; MtnDon's Entry, Hand Made Class

It’s the first one I’ve seen and a perfect application. I didn’t even know it existed before.

Just a memo to state that if anyone has thoughts of playing around with a remote phosphor Arrow Electronics has some of the Chromalit products in their stock.

For the month of September they have free shipping with no minimum special going on. That’s limited to the USA for the no minimum part. International has a US$50 minimum to qualify for free shipping.

Hmm, they also had the Ledil Cute-3 optic for awhile. I’ve been wanting to do something with an umbrella and this would be perfect, thanks.

Mug’O’Light, Mk. II

Can’t leave well enough alone…. :wink:

I had glued up an extra block way back there at the beginning. This one has the same walnut and padauk but has red oak in place of the maple. This afternoon I couldn’t resist drilling some holes I had marked out a few days ago. I may not have sufficient time to complete Mk. II by October 31. If I do I’ll nominate only one of these to be my official entry. I hope that is okay with the letter and the spirit of the official rules that permit only one entry per person. Anyhow here is the start….

The larger hole is space to be used for two TP4056 charger boards along with a heat sink that will cool to the outside of the mug. That is the biggest plan addition / change. I have some NCR18650, 3400 mAh cells I plan on using. That will give 85% of the capacity of the 4 Samsung 30Q’s I used in the original. That will still be plenty of run time and I don’t need the high drain of the 30Q’s in either of these. I’m also planning on cutting out another 7135 and using two. From what I have seen with Mk. I this should be quite adequate for the designated purpose.

I have a mini voltmeter thanks to Lazy-R-us, which I am going to try to add the Mk.I version as a modification to the original. It would be nice to know the SOC of the cells.

evolution….

I like the idea with the charger boards & voltage meter.

Good luck with MkII.

+1 here.

Well, the MK2 version will not make it in time to be placed in the contest. So, we go with the original with a slight mod. Today I drilled one small hole, soldered two connections and placed a mini voltmeter inside.

The meter is on whenever the light is on. I did not measure the mA draw for just the meter. I meant to but forgot. So this is just a gap filler measure. The MK 2 version with the charger will also incorporate a mom-on push button to take the voltage reading. But it will have to be “just another” project to be (hopefully) completed in the next month or so.

Thanks for looking.

No pun is intended with this. :beer:

The ultimate in clear ano.

Just downright neat!!! We have pickle jars, peanut butter jars, all kinds of jars…… and now a light jar…WITH A HANDLE!!! Just too cool!!!

Congrats on the build and thank you for letting us all watch!! :+1: TL

These two comments are priceless…. Both correct too!! :wink: TL

Just thought of this and had to…… call it “Mug O Lite”. :innocent: TL

Nice build.

Ok fellas , let me shed some incite on this ripped off material they call remote phosphor. its just a florescent yellow with blue laser or led.
any combination of yellow and blue makes white lite. The only challenge you may encounter is making sure you find yellow fluorescent pigment, paint or nail polish that retain a yellow glow under regular light and under uv light, most of the yellow glows green under uv. The second option , you could mix bright blue fluorescent(better with optical brightener blue) and a little orange fluorescent marker fluid with a uv purple laser. The uv laser shine on blue and orange fluorescent will make white glow also. In this case the blue glow substance replaces the blue laser and a little orange will complete the process. Its an order of operation, uv laser makes all the colors glow, follower by blue and green… in other word, uv laser can make blue substance glow blue, but blue laser cannot make uv or blue substance glow, blue laser can only make green, yellow and red substance glow. In conclusion you can use blue laser/led with fluorescent yellow or uv laser with blue and orange/yellow fluorescent substance. For some strange reason blue led/lasers are more expensive. The fluorescent yellow is also hard to find, but use your common sense and grab you a uv laser and take it to your local hardware to get some none green neon yellow. if the yellow glows green using your laser\led , then its not the correct yellow. green and blue neon substance will give you a aqua glow, not white lite…

Welcome to BLF! So, are you saying that one could paint a clear surface with fluorescent dye and that would make it the same as a “remote phosphor” dome for all intents and purposes? Have you done this before? What brand of dye works best for this?

I have re-hosted and re-linked all the images in my build thread to resolve the photobucket no-show issue
No other changes.

Nice work MtnDon. I need a bit of your motivation.

I kept putting it off, then was prodded by an old friend from back home saying he couldn’t see the images…………
