The equipment for high-speed photography isn't cheap or simple. Edgerton is an open-source high-speed LED flash that can produce sub-microsecond flashes. The materials to build the flash are readily available, and this fully-assembled control board connects all the electronics!
Includes the microcontroller, gate driver, and solid-state relay required to run the flash. The microcontroller has the most recent firmware version (0.2.7) and has been calibrated and verified using an oscilloscope.
For more information on assembling the flash, please see https://hackaday.io/project/165622-edgerton-a-high-speed-led-flash.
Input voltage: 8.5V - 18V
Clock speed: 8MHz (can be upgraded to 16MHz)
Gate current: 13A
Flash duration: 0.5us (microseconds), 1.0us, 2.0us, 4.0us
Display output: Connects to TM1637 7-segment display
Encoder output: Connects to EC11 encoder (see KY-040)
Trigger input: 5V active-low OR active-high (autodetecting)
Trigger delay: <=2us
Currently all available boards are completed but do not have audio buzzers. The parts are on order but have not arrived. At this point, all boards will be shipped without the buzzer. It can be purchased from eBay/Banggood/Aliexpress and installed very easily.
When the remaining boards are sold then I will make an order for more PCB's in larger quantity.
