How about using these for experiments, free research, or other crafting projects? These are from 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, etc., are not included. I do not know the detailed specifications of the circuit board parts, such as capacitors and flash xenon tubes, so I cannot answer questions about them. Please search for more information. Warning: The flash (strobe) circuit has high-voltage parts (300V or more). Even if the battery is removed, high voltage continues to be charged in the capacitor. The capacitor will be discharged after removing the circuit board. Disassembly is at your own risk. Warning: All items are removed from used cameras and are not new. I have not tested their operation. Battery contact terminals and other soft metal parts may be bent. There may also be occasionally damaged or old parts. Please consider these as junk items. Warning: Shipping 10 pieces will be via Nekopos. Due to the low-cost shipping, the thickness limit will be exceeded, so reinforcement with packing materials such as air cushions will not be possible. Please understand that we cannot guarantee that they will work upon arrival, so we will state that they are junk items. *No price reductions. Thank you for viewing.
