CRX Stratis Lumina - 2017 5th BLF Scratch Made Light Contest Winner

Ah yes…… time for the group buy! :stuck_out_tongue:

You have to love a good looking piece of wood. How big is the vice?

That one has 4” jaws and a maximum 4” opening, I have two small tabletop vices that I use, not fixed down to anything so that can be fun sometimes :slight_smile:

It’s even harder working metal when all you have are wood working tools. :wink:

I like that wood. Looking nice.

That vice (with the orange button) looks like a twin to one of mine.

I can totally understand that :smiley:
I thought about the wood for a while going between american walnut, ebony, rosewood and a couple of others but being honest I chose this piece because it was the closest cut to the dimensions I required :wink:
Yeah an ex got that vice for me at lidl about 7 years ago, best thing she ever bought me :slight_smile:

Crx it is already looking awesome !!!

Thanks CRX. The reason I asked how big the vice was is to get an idea on how big your parts were.

Thanks mate :beer:

Right :slight_smile: , well looking at the lights parts from the front is about the same size as a credit card, 85mm x 54mm and maybe 20mm thick total.

More work on the rosewood, drilled 3mm holes for the red bottom LED's, charging indicator & top momentary switches and cut out a channel for the USB charging port with a junior hacksaw.

Had an idea to cover the back end of the auxiliary LED's with a mix of glow powder and resin.

The USB port I have taken from an old converter that I had.

Sanded down two momentary switches.

Marked out and drilled holes for wiring in the mid copper layer.

Bits n' pieces.

Cool! Looking good.

Sure is.

Someone has to ask , what kind of black magic is this ?

lol , good idea right there

The project is coming along quite nicely.

I love watching this rapid prototyping take place.

Some great out of the “box” thinking.

Sorry I had to say that.

Anybody else still confused about what this is supposed to turn out like? I looked at the renders in the OP, and all these progress pics, and it still eludes me. I see it has a quad? And then the 5mm AUX LEDS go on the “bottom” along with a charging port?

All will be revealed :wink:
Yeah, quad main light, some UV emitters around that and red LED’s on the bottom.
Two momentary switches, one for the quad driver, one for UV resistor driven and a mercury tilt switch for red LED’s on the bottom. Rechargeable via micro USB port, built in TP4056 or TP5000 charger board.
Are you saying my drawings are crap? :smiley:

Of course not. :innocent:

Good, coz they took ages :smiley:

Your speaking Chinese CRX. Can you put that in English so dummys like me understand? :stuck_out_tongue:

You’re not as daft as you make out moose :laughing:

Got the copper layers & wood marked up and drilled for the brass fixing screws today, very hard to get these lined up straight without using a drill press but I did ok.

Copper layers.

Copper & wood layers lined up.

I used a scrap piece of copper to test and show how I will be installing the slotted M2 screws into the front and back plates.

I think I will practice some more before working on the finals :D

Something else I have thought about is etching the copper with my username as shown in the mock up drawings, I did a small test on the scrap copper with some ferric chloride.

I cut out a disc of tape and applied then used correction fluid to mask, left to dry then removed the tape. I dabbed on some ferric chloride and left for an hour then brushed up the copper, just to see the effect. It leaves a shallow etch in the copper.
