100W Flashlight

thingiverse

Here are the files and the code for a 100W flashlight. The flashlight has an OLED display that shows the temperature of the heatsink, brightness, fan speed, battery voltage, and battery percentage. The fan are temperature-controlled and begin to run at a specified temperature. 
 
 About the code: Everything works except the strobe light function that I wanted to add. Right now the strobe light switch (the small switch) works but I can only get it to turn on and off every second. The plan is to make it possible to adjust the frequency of the strobe light with the potentiometer and display the “Hz” on the display.
 
 Here are the parts you need: 80 mm fan and heatsink: https://www.aliexpress.com/item/32799938839.html?spm=a2g0s.8937460.0.0.67ed2e0eKrxKWG or https://www.aliexpress.com/item/32834284199.html?spm=a2g0s.8937460.0.0.67ed2e0eKrxKWG or https://www.aliexpress.com/item/32590832163.html?spm=a2g0s.8937460.0.0.67ed2e0eKrxKWG 100 W LED: https://www.aliexpress.com/item/33029340248.html?spm=a2g0s.9042311.0.0.64304c4dKFjfne 100 W LED lens: https://www.aliexpress.com/item/32954482742.html?spm=a2g0o.productlist.0.0.61ad5464CUzY6c&algo_pvid=d5ab664c-2cd0-4576-a59a-e23b1b06b55d&algo_expid=d5ab664c-2cd0-4576-a59a-e23b1b06b55d-0&btsid=0ab6f83a15841971098515398e0a61&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ 40 V boost converter: https://www.aliexpress.com/item/32793476482.html?spm=a2g0s.9042311.0.0.27424c4dMd2TYL 5 V buck converter: https://www.aliexpress.com/item/32742116421.html?spm=a2g0o.productlist.0.0.718c161a2XqBQz&algo_pvid=32502b19-91d2-4108-856f-78012bc4a60c&algo_expid=32502b19-91d2-4108-856f-78012bc4a60c-0&btsid=0ab6d69515841976131712099e730b&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ Power mosfets: https://www.aliexpress.com/item/32892361290.html?spm=a2g0s.9042311.0.0.64304c4dKFjfne Arduino nano: https://www.aliexpress.com/item/32341832857.html?spm=a2g0s.9042311.0.0.27424c4dlHESQT Mini OLED display: https://www.aliexpress.com/item/32896971385.html?spm=a2g0o.productlist.0.0.12d7131d9n7osZ&algo_pvid=de720bfb-d628-4c96-9c00-140b04b61899&algo_expid=de720bfb-d628-4c96-9c00-140b04b61899-0&btsid=0ab6f83915841976745894717e31b2&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ Potentiometer: https://www.aliexpress.com/item/33040874339.html?spm=a2g0o.productlist.0.0.149a24adegJWp5&algo_pvid=d56b50df-74e2-4cbe-a606-af5ca7d67594&algo_expid=d56b50df-74e2-4cbe-a606-af5ca7d67594-31&btsid=0ab6f81e15841977322257602e47bb&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ 10K and 100 K resistors: https://www.aliexpress.com/item/32687413849.html?spm=a2g0o.productlist.0.0.1b7bff11IohKz4&algo_pvid=6686d1ea-d036-439a-a5f8-cddd215223dc&algo_expid=6686d1ea-d036-439a-a5f8-cddd215223dc-1&btsid=0ab6fa8115841978696782012ef81b&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ 100 K thermistor: https://www.aliexpress.com/item/32812361274.html?spm=a2g0o.productlist.0.0.283943986eGqLf&algo_pvid=1cb77efa-bee0-46dd-92ff-a71c2adbd277&algo_expid=1cb77efa-bee0-46dd-92ff-a71c2adbd277-0&btsid=0be3743615841980081088266e6241&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ Big switch: https://www.aliexpress.com/item/32985767697.html?spm=a2g0o.productlist.0.0.61ccb7b9SsXKHR&algo_pvid=64a59585-87f7-4098-92d9-722efd68c18b&algo_expid=64a59585-87f7-4098-92d9-722efd68c18b-46&btsid=0ab6f82315841981376463766e66ff&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ Small switch: https://www.aliexpress.com/item/32778940378.html?spm=a2g0o.productlist.0.0.718e2338ly1Ge9&algo_pvid=013280ad-8063-4889-a2e2-4037781c723f&algo_expid=013280ad-8063-4889-a2e2-4037781c723f-3&btsid=0ab6d67915841982223686031e6e61&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ 18 AWG wire: https://www.aliexpress.com/item/4000009001537.html?spm=a2g0o.productlist.0.0.7578747euDJCzc&algo_pvid=fcfb684d-23f3-441e-a81c-df41a8df471c&algo_expid=fcfb684d-23f3-441e-a81c-df41a8df471c-8&btsid=0ab6f83115841982877926866eab1f&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ 18650 batteries: https://www.aliexpress.com/item/32807032859.html?spm=a2g0o.productlist.0.0.455d670aYLR5XO&algo_pvid=65513c20-85f0-4e33-ab15-b4626ceb0d4b&algo_expid=65513c20-85f0-4e33-ab15-b4626ceb0d4b-0&btsid=0ab6fa8115841984946471977ef76a&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ XT-60 connector: https://www.aliexpress.com/item/32888533534.html?spm=a2g0o.productlist.0.0.192b4a80tEaJNn&algo_pvid=6af28055-4f01-43ed-b0c3-0d7a1fdb3486&algo_expid=6af28055-4f01-43ed-b0c3-0d7a1fdb3486-2&btsid=0ab6fa8115841985446013169ef7e4&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ 18650 BMS: https://www.aliexpress.com/item/32817897264.html?spm=a2g0s.9042311.0.0.27424c4d9n15Xj Battery capacity indicator: https://www.aliexpress.com/item/32947209170.html?spm=a2g0s.9042311.0.0.27424c4dBvBkTY 3S battery charging connector: https://www.aliexpress.com/item/32639607989.html?spm=a2g0s.9042311.0.0.6dcb4c4dIEehdz
