10 small DIY flashlights for the kids at school to build
Small DIY flashlights for the kids at school to build
This is 10 complete kits. They use AAA batteries. All parts fix snugly into the great little case. These can easily be modified for other uses or simply different color LEDs. They also work just fine with AAA Ni-MH rechargeable batteries.
good little kits,circuit is a joule thief ,so you can use partly drained batteries.
هذه العدة كانت كما وصفت تماماً أنا سعيدة جداً وسأطلبها مجدداً أستخدمه في تعليم الإلكترونيات لطلابي وهم جميعاً منبهرون.
الشحن السريع وجميع الوظائف تُعطى.
👍👍👍👍👍
good!
Easy to assemble and a great project for anyone learning to solder.
Really good piece of kit. Pretty easy to put together, but the battery holder springs are a little fiddly. We used these kits to introduce a group of childern (ages 9-11). Most of the kids got them to work- one or two needed some trouble shooting, but all worked. Really anjoyable exercise, though additional (adult) help needed with the battery holders.
