thingiverse

It seems like you're sharing a DIY guide for creating a super-bright flashlight using a cell phone battery and various electronics components. The total cost of the project is around £11.42, which is impressive considering how bright the resulting flashlight is. To summarize the steps: 1. Print out the square post and housing enclosure. 2. Use a M3x30mm screw to create a brass insert that will hold the screw in place. 3. Heat up the brass insert using a soldering iron while holding it over the square post's hole. 4. Press the brass insert into position, making sure it is straight. 5. Repeat this process for all posts. 6. Use two M3x10mm screws and two M3x20 screws to assemble the top part B and taller Part A. 7. Assemble the flashlight by attaching the LED bulbs, push button switch, DC to DC step up PCB, lipo charger PCB, voltage regulator, capacitors, and fan. Some key points from the guide: * The flashlight is extremely powerful for just using a cell phone battery. * It uses five of the 12v LED bulbs, which are meant for cars. * Charging only takes an hour, thanks to the 1 amp fast charge module. * The total cost of the project, including shipping, is around £11.42. It's also worth noting that this guide includes some important safety considerations, such as not touching the brass insert or unscrewing it until it's back at room temperature, and using heat-proof gloves to handle hot components.
