Updated in May 8, 2017: magnifying glass projector can be used as a scientific experiment. If the requirement for clarity is not high, it can also be DIY. If you want to use the phone shoe box projector to see the movie, the shopkeeper does not think this definition is enough. The main out of the image will be a bit dark, and if there is a good way to solve it, welcome to me, and I'll share it here.
This lens is custom-made for a friend who likes DIY and gives a projector lens circle.
Note: the sharpness of the magnifier can not be compared with the professional projector, and the brightness can only be based on the brightness of the mobile phone. There is no problem in doing scientific experiments. Do not make a request for clarity, thank you!
The following is the process of making the cabinet!
The following is a special need to pay attention to the repeated experiment in the hand cabinet.
The level of the hand cabinet is limited and can only be made so, but the cabinet is also very successful!!!!
April 20, 2017 update: as the treasurer itself is a magnifying glass production factory, so there will be a lot of hand sizes lenses are available for production, after repeated testing of various types of dispensers lenses, this lens made effect, this is just shopkeeper himself shot. (if you want to take a play, please set up a mobile phone for S:1.2EV:4.0.) For the convenience of the people, the cabinet made a schematic map:
Please note that the above size is only suitable for this type of lens.
Measured in the cabinet, the width of the screen is about 1.2 meters when the lens lens is 2 meters away from the wall.
The fun of DIY is not what you finally get, and the process itself is full of fun! I wish you a better projector than your hand!
