Electronics tech of 45yrs. It combines everything we need, a laser-Diode, a lens with variable Focus and a photodiode. As you can see the three push buttons and male headers are clearly labeled as REC, PLAYE, PLAYL, VCC, GND, FT, P-L, P-E, and REC. I recommend a 480x320 Display (no touch), which you can get on ebay for less than 10 USD. Grove - Servo. I used the SPI to send values between 0 and 5V to the outputs of the MCP4922, but I don't know how the loop need to be for a good control. Finally everything is mounted on a wooden plate and all the outputs and potentiometers are mounted too. My idea was to use a laserpointer to point it on a window and let the reflected beam point on a LDR and use the values of the light intensity to play them through a 0.5 Watt 8 Ohm speaker. Grove - Temperature & Humidity Sensor Pro. I'm sure there's interferometer circuits that can use the phase of the returned signal compared to the outgoing signal to determine the doppler shift of the laser coming off the window. To drive the Speakers I use a MCP4922-DAC. Fig. Quote from: weedpharma on Dec 30, 2015, 06:07 am. 3 years ago. Maybe you'd like to take a look at my YouTube-channel (https://www.youtube.com/user/stopperl16/videos). 6,99 € 6,99 € Recevez-le demain le 21 novembre. Pages: [1] Topic: DIY laser microphone (Read 1 time) previous topic - next topic. Changing the current through the focuing-coil you'll see, that the Output-voltage of the photodiode first increases, going through a Maximum and then decreases. Using a single photodiode we just get one signal. These differences in sharpness can you see in my results were images are taken with red, green and uv lasers. and I'd be very happy if you could vote for me in the microcontroller-contest :-). Add to Cart. The larger the value of the potentiometer, the higher the magnification. Battery Powered Lamp That Turns on Through the Use of Magnets! (LDR With a pinhole): 3,6 V in focus and 0,3 V with nothing in the light path. If you lay a few readymade different types with the label side down on a table its hard to tell wich is wich, they are all silvery. To do this off a window will require a better method. Laser microphones are often seen as the pinnacle of spy technology as you don't have to install a transmitter to hear what's going in a building. The only additional parts you'll need are a multimeter for controlling the photodiode-voltage and a power supply (9V, 0.6A). New. The arduino is able to read voltages between 0 and 5V. 3,8 sur 5 étoiles 17. I have used four different (red, green, blue and uv) lasers to magnify a cd, and the uv-type (shortest wavelength) has the sharpest picture (see my samples below). With those signals you're able to find out the Focus quite easily. Details. Exactly in that maximum the laserbeam is focused right. This likely rids you of the interleaved looks of your images. What do you think. Have you used those two programs, one (Arduino_Lasermikroskop_Processing) for the arduino and the other (Lasermikroskop_processing.pde) for the processing itself? There are indeed differences in approach between our LSM's. Question Feb 10, 2014, 02:27 pm. Trying to remember programming C from 25yrs ago. Older cd-drives are suitable for the laser microscope because they aren't so miniaturized like modern drives. Bstanko6 Guest; DIY laser microphone. http://www.rinkydinkelectronics.com/library.php, https://www.youtube.com/user/stopperl16/videos. As soon as the beam hits the photoresistor, the impedance will vary significantly and you will hear a pop and probably a bunch of noise. With the 10 kOhm potentiometer at the base influences the magnification. $3.30. Where mine ( "https://www.instructables.com/id/Laser-Scanning-Mic... for the interested!) In a laser pick-up however it must be excellent. I also don't think the response will be quick enough for audio. The finest scale is 0.01mm, so 10µm. At the end of the bar a small piece of copper-foil (0.5 mm thick) is soldered with the bars. € Recevez-le demain le 21 novembre Micro 130 DC Motor 3.3v for Arduino MKR Carrier! ’ s check how this Module can be easily realized with a TFT-display Arduino is able read!
