LLLT laser therapy helmet for hair loss

thingiverse

This is a prototype LLLT (Low Level Laser Therapy) helmet for treating hair loss, designed for both men and women. I created this as a hobby project for educational purposes only, and I strongly advise against using it as a medical device without proper training or certification. This helmet features 50 red lasers, which are the key to its functionality. To assemble this helmet, you will need the following components: * 50 5V, 650nm, 5mW lasers, available on AliExpress (https://de.aliexpress.com/item/10Pcs-5V-650nm-5mW-Laser-Red-Dot-Module-red-laser-sight-red-laser-diode-laser-pointer/32655789184.html) * An infinite cycle delay relay switch, similar to the one found on eBay (https://www.ebay.com/itm/DC-5V-12V-24V-Infinite-Cycle-Delay-Timer-Relay-Switch-Delay-Turn-ON-OFF-Module-/262487677778) * Some cables * 3 AA batteries * A 3D printer to produce the helmet's parts The stoppers, which provide flexibility and comfort for the helmet, should be printed in TPE with a 20% infill. The rest of the solid parts can be printed using your preferred type of solid filament. To assemble the helmet, follow these steps: 1. Glue base-a.stl and base-b.stl together to create the base mesh/net for the lasers. 2. Remove the lenses from the laser modules and replace them with new ones. 3. Insert the lasers into their designated holes, making sure they do not protrude. 4. Wire the lasers and remove the wire from the hole in the base ring. 5. Glue top-fill1.stl and top-fill2.stl together to create the top enclosure of the helmet. 6. Attach the stoppers to the helmet. Once assembled, you will have a helmet with two wires ready to be connected to a power source. You can use a 5V DC adapter, a battery box with 3 AA batteries, or solder a male USB connector to plug it into a phone charger or laptop. It is recommended to also install an infinite cycle delay timer and set it to turn off every 10-15 seconds to prevent the lasers from blasting for extended periods. My current build uses a 3xAA holder from Thingiverse (https://www.thingiverse.com/thing:456900) and a power cycle module with an on/off switch. Happy building!
