Super Capacitor Flashlight

Here is a really cool flashlight design. that Instructables user EngineeringShock built that charges a bunch of caps and charges via a 9v wall wart. Unfortunately, super capacitors can only be charged to lower voltages; typically around 2.5v or 2.7v as a standard. If you place some super capacitors in series, you can charge to […]
