4 months ago If you're looking for more precision, you might consider switching to stepper motors over servos. Bonjour je voudrais vous commander un kit complet, avec les composants , est ce possible ? Excuse me, I tried to build a sample. And that's it, now you should be able to control the galvos with step and direction signalsYou can connect the step and direction signals directly to the STM32, because I have activated internal pull down resistors. Later I want to become an Electrical Engineer :-) https://www.instagram.com/vulcaman/ Merci The both signals have the same amplitude, but with changed polarity. You have link to a more detailed description or visualization to the mentioned setup? Some years ago "Scientific American"'s Amateur Scientist series had an earth field magnitometer (I know the spelling is wrong) that used a Neodymium Iron Boron magnet to measure changes in the Earth's magnetic field.

https://metodosgeofisicos.files.wordpress.com/2007/04/0199106b.pdf I went with servos because of their easy availability. 1 year ago Using an Arduino and a pair of servos to create a laser show on a sheet of luminous vinyl. Fun, but even better if we can computer control the laser beam!I’ve come up with a hardware platform that I hope will let me start simple but then experiment with more complex ideas.I’m using off the shelf servos driven by an Arduino to steer the beam from the laser.There are two servos, one for the x axis, one for the y. I’ve attached a small circular mirror tile to the servo.This stand is made from 3mm laser cut ply – there is a pdf of the parts attached - glue the pieces together using PVA glue. Also I have used 5V tolerant pins for the step, direction and center pins.You can download the full schematic of the circuit below:The STM32 is programmed with Attolic TrueStudio and CubeMX .

You don't need servos. This project was These task are: The first task is to measure the input signals. The servo driven mirrors steer the UV laser leaving a phosphorescent trail on the glow-in-the-dark vinyl sheet. Starting with a sheet of luminous vinyl from eBay and a UV laser pointer. About: I am a 21 years old student from Germany who love to make things.

About marking the nominal values of the resistors: take instead of R, for example, 2k, then 2R will be 2 * 2k = 4k (3.9k), and 4R - 4 * 2k = 8k (8.2k).I use: 1k, 2k and 4.7k Buttons.

If I shine the UV laser pen on it there is a very bright glow which fades very quickly. Thanks for your answer,I Will try this way.And I found something problem in the schematic about ILDA_X and Y R7 R9 connect to TL082's foot 2 Because the DAC is unipolar 0-4,2V and you need -+5V bipolar for the ILDA standard, you need to build a small circuit with some OpAmps. An Arduino Uno project that utilizes a laser to detect when the laser beam has been interrupted. Create a People Counter Controlled by an Android App. So are you saying in step #1 that if I shine a laser pointer at an old CRT TV, It will glow a bit? 1 year ago Project tutorial by ... Make a people counter that detects the number of people who enter the room using lasers and LDRs and control it with an Android app. and last updated 6 months ago.   4 years ago UV laser pens leave a luminescent trail when shone on glow-in-the-dark material. Here I will you explain, how the controller works in general. Reply Arduino controlled laser galvo. Reply Reply No more than a few seconds - you can see the fade on the YouTube video. 1 year ago

4 years ago What I got was the basic guts of a laser light show system. Because I don't want that the motion-controller will be limited by input frequency, I designed the circuit for Now the controller needs to compute the signals to the right value for the DAC.
