How about using these for experiments, free research, or other crafting projects? These are used disposable cameras, used once. The camera body is shown in the image, but only the circuit board will be shipped. The camera body itself is not included. The LEDs currently in stock are red, as shown in the last image. I do not know the detailed specifications of the circuit board components, such as capacitors and flash xenon tubes, so I cannot answer any questions about them. Please search for more information. Warning: The flash (strobe) circuit has high-voltage (300V or more) parts. Even after removing the battery, high voltage continues to be charged in the capacitor. The capacitor will be discharged after the circuit board is removed. Disassembly is at your own risk. Note: These are all removed from used cameras and are not new. I have not tested their functionality. The battery contact metal fittings and other soft metal parts may be bent. There may also be occasionally damaged or old parts. Please consider these as junk items. Note: Shipping for 10 items will be via Nekopos. Due to the low shipping cost, the thickness limit will be exceeded, so reinforcement with packing materials such as air cushions will not be possible. Please understand that there is a possibility that they may not work upon arrival, and that they are junk items. *No price reductions. Thank you for viewing.
