griff_4988 No, because as the specifications on the webpage say, it’s designed to work on a supply between 3V and 5.5V. A 2S lipo is 7.4V.

griff_4988 I have the twin strobe version of this, and have measured the peak current at about 450mA (with each peak related to a strobe flash), and the average current at around 150mA. So I think the answer to your question regarding the Arduino, is no.

grahamgpearson Using the D button, press until the icon on the top left of the display changes to a camera with a plus sign in its lens. Now press the OK button. The picture will be taken. To take a movie press the D button until the icon changes to a movie camera. (The default when the device is powered on). Now press the OK button. A red flashing Recording icon will appear. Press the OK button to stop, The pictures-movies can be viewed by selecting the icon that looks a bit like a mountain range. Use the zoom button to scroll though the pictures-movies. Hope this helps

Not a bad piece of kit for the money. The image on the 7 inch LCD is quite sharp, however don’t believe the claims of 1200x magnification. Using two rulers, I put one under the microscope, and used the other to measure the image on the screen. The maximum I could achieve was about 120x magnification, and that was with 4x digital zoom selected. So the true maximum optical magnification is nearer 30x (120 / 4).
