Making a DIY caving light

[YuvalS]

I know someone who build something similar

This light is from scratch:

YuvalS's Hand Made Class, 7th Annual BLF/OL contest entry topic

So I am planning on building a headlamp, hopefully I will finish it by February. The body will be made of aluminum to double as heat-sink and the battery box will be made of some kind of plastic. both will be build using hand tools. I want to print my own driver but I have no experience with printing circuits so maybe I will use a commercial driver and modify it. As a FW I am planing to use my own code that is need some improvements. Welcome to share your thoughts. Yuval EDIT: 2…

This one is inside an old Elspleo (I have sone hosing for sell if you interested)

YuvalS's Modification Class, 8th Annual BLF/OL contest entry topic

For this year's competition I decided to renovate an old dysfunctional caving light. Some time ago, I bought a box full of defective caving lights that people sent to the retailer for repair under warranty and he decided it is not repairable.

For this year challenge, I want to rebuilt a classic caving headlamp: the Petzl Duo Since the 90's this light considered as the best caving light by the many cavers because of its great durability and waterproofs. During the years many upgrades to the original light tried to keep it relevant with recent LEDs impro…

And another one from scratch

YuvalS's Hand Made Class, 10th Annual BLF/OL contest entry topic

This year I am joining the party relatively late. As every year I will build a caving headlamp but the innovation this year will be in the user interface. I plan to create a switchless UI, using voice commands. The reason I'm toying with the idea of a caving headlamp with voice recognition is that it is very complicated to switch between all the possible lighting modes of a dual optic headlamp: focused, diffused, combined and all different intensities with using only one or two switches. I'v…
