(have no idea how it is called)

“Catch plate”, orsometimes “hook”

Thanks, everyday you learn something :)

I want to use screws for connecting the GoPro mount to the housing since a lot of force is applied on this point while tilting the lamp (and when banging the helmet in the cave ceiling).
Because the housing is mad of thin Aluminium, I decided to tap the mount.

In order to add strength and also improve the heat dissipation by conduction some of the heat to the mount, I have also glued tho mount using a heatsink plaster.

Screwed everything together and have to wait for it to cure.

Those are called “draw latches.” Also known as tension latches, according to Mcmaster-carr.

So today I also learned something new :)

this is actually the last day for the build because i don't have any more time and I have to complete the light today.

Did some more drillings.
For the microphone I had to drill trough the GoPro mount and it was hard to measure and place the drill bit.
Luckily I was able to drill from the inside, via the switch hole.

And it went almost as planned (this screw was already filled to correct length)

Also drilled a hole for the USB port.

Re: the latches… Yours are also “over-center toggle latches

Time to work on the electronics.
soldered the Microphone and added a SMD capacitor to cancel some noises.

Check everything is working before final assembly.

Isolating the microphone body (connected to GND) using a shrink tube.

Although trying relay hard I did not manage to finish the light today and I have to go to sleep (almost 5 AM) I did complete most of the work but still have some assembly left, mostly soldering.
I do have some hope to finish tomorrow before the deadline.

I glued the MPCBs and lens using heatsink plaster so it now looks like a caving light.

Also glued the microphone and button.

And added Fet transistor for the spot channel and 105c with 7*AMCs for the flood channel. protected everything with shrink tubes and soldered all wires.

Tomorrow I have to add the voice recognition module and the Arduino, solder the battery box and add the rear and front covers....

Love how it all started to come together and take shape so quickly. Well, the pictures make it look quick but I know that’s some serious application of elbow grease. Good job and keep it up, almost there!

Looking good, you are on the home stretch.

MtnDon · 2022-10-30T13:06:37.000Z

Looking great Yuval.

MascaratumB · 2022-10-30T22:42:16.000Z

Can’t wait to see this one finished and with demonstration
I guess I’d like to have something like this, voice activated !
Good work YuvalS

NeutralFan · 2022-10-30T23:22:51.000Z

A voice activated headlamp! YuvalS taking it to the next level.

YuvalS · 2022-10-30T23:29:10.000Z

Thank you guys for all the support,

Indeed everything take a lot longer than it seems in pictures (I don't post pictures of all the failures :) )

Hope my thread was informative enough, I did skip some stages yesterday since I worked fast.
The code will be available in my Git repository.

YuvalS · 2022-10-30T23:35:06.000Z

Today I also hat to work into the night and completed almost everything.
I have soldered all the PCBs and other components. this build reacquired a lot more soldering than a standard light.

Also placed the front Perspex window.

And glued the micro USB port.c (probably was a lot easier to buy it from AE instead of making it by myself)

YuvalS · 2022-10-31T03:26:50.000Z

Just completed the final tasks and completed the light. Tomorrow I will update a video

Add another Perspex for the back side. Since I have enough cooling from the aluminum plates I think it will look better with a transparent back reviling the circuitry. Also the LEDs provide some info on the recognized words.

Soldered the wires for the battery box.

Colored it with some nail polish to indicate correct polarity.

lumenzilla · 2022-10-31T03:43:29.000Z

It looks promising. Can’t wait to see the final result

bobvoeh · 2022-10-31T04:32:51.000Z

This looks great. Looking forward to seeing it in action.

Thanks for the heads up Hoop. It could be easy to miss the update in post #2

Looks nice Yuval. Good to see it work
