@Anderson Jude i really appreciate your reply. I found the site on google and I'm trying it out atm. I see it takes quite some time so I will reply here later with my results.
Very nicely done. I've experimented with using magnets for rotary encoders before, but in a different configuration. I really like your idea. Very slick!!!!
I found this video interesting, alright. I will order some magnetic angle sensors and play around with them. Seems very useful technology and will no doubt come handy some day.
Another tip is to solder the end pins first and then you've got everything mechanically sound and can finish up the rest. This tip works well with or without the breadboard.
That's a good tip. Also works very well with header pins in an awkward place. Solder one of the pins and then you can adjust it easily to get it square before soldering the rest.
This is really neat. I've been wondering how to interact with a hermetically sealed device for a dive light project I've been working on, and I think this magnetic sensor configuration might be the answer. I applaud your ingenuity for repourposing the encoder shaft with a simple 3d printed addition👏🙌👌. A+
Sounds like a great project. You would probably need to do some experiments to see how far away the magnet can be and if there's any impact from having some material in between the magnet and the sensor.
Thank you for a great video. Was looking for an alternative way to decode an angle for a DIY joystick with a finer resolution than the standard potentiometer. This will be the ticket I think.
DESoldering any part is very easy. You need to hold the board with pliers, and gently pull it with others, holding it all over a regular electric stove.
Wireless control is quite easy to do between 2 ESP32's using Bluetooth serial - one as master the other as the client. I made a handheld game recently that used Bluetooth Serial to communicate between a pair of controllers, it works quite well.
@@atomic14 I just started with the example code github.com/espressif/arduino-esp32/blob/master/libraries/BluetoothSerial/examples/SerialToSerialBTM/SerialToSerialBTM.ino and github.com/espressif/arduino-esp32/blob/master/libraries/BluetoothSerial/examples/SerialToSerialBT/SerialToSerialBT.ino then I got the master to connect to client device. They each sent shared game state messages to each other over the BT serial connection. The connection between two esp32 devices worked ok up to about 10 meters and the connection was stable for over 24hours in my testing.
@@sharpbends 250 bytes I think - but - if I can get it to build and run fast enough - I'm going to try using a codec from the days of GSM that compresses speech down really aggressively.
The search phrase you are looking for is "Diametrically Magnetised Magnets". Something like these: amzn.to/3PUhzBp and here's a breakout board to match: amzn.to/3PUhzBp
It could also be built into an old potentiometer, without the need for any 3D print item. The pcb may need cutting down a bit on the corners to fit into the pot's can.
They are relatively expensive compared - around £7 depending on how many you want to buy. There are some evaluation boards but they seem to be around £14-20. I was quite lucky that Rob Dobson (th-cam.com/channels/ScxC8mTWRU_ARb4nC3vIUw.html) had one spare from another project he was able to give me. You are correct they are hall-effect sensors - there are a few alternatives at different price points and quite a few from other manufacturers.
Nice work fine tuning the code for the AS5048. I am curious how did you resolve the angular position data from the AS5048 to incremental movement in the Asteroids game control? More to the point, I am interested in converting angular position to quadrature motion because the AS5048 has finer resolution than many other encoders with quadrature output.
I'm just reading the angle from the AS5048 and using that to set the angle of the space ship. So its direction the ship is pointing is directly connected to the angle the AS5048 is sensing. I think what you want to do is use the AS5048 but output a quadrature output? Definitely doable, with a bit of coding. A simple approach would be to periodically check the angle reported by the AS5048 and compare it with the angle you got last time. You could then output the appropriate quadrature pulses to count up or down to the new angle. You would have a bit of latency but I don't think it would be noticeable.
That is a really good idea. How good would this be as a angle sensor for wind? I would need a very loose and lubricated axis, but other than that, your project covers everything, I have to try that! thanks for the video
I think it could work well, presumably for wind direction rather than for speed? There are also cheaper magnetic sensors as well - not as accurate (1 degrees), but I think for most applications sub degree accuracy is probably not really needed.
Someone suggested the TLV493D as an alternative www.infineon.com/cms/en/product/sensor/magnetic-sensors/magnetic-position-sensors/3d-magnetics/tlv493d-a1b6/
Hello Atomic14. Good video , thanks for the detail. A question a little off topic that I hope you wont mind. Was that a laser projected Asteroid game ? Did you make it ? where can i get details about that ? Thanks again.
@@perfoperfo9910 Thanks! Apologies for not replying to your original message - the code for the game is all on GitHub - details on the video here: th-cam.com/video/LXDwGygCokU/w-d-xo.html
@@atomic14 hey no apologies Atomic14 there was about 20 minutes between my question and my own update. I don't think it would have been reasonable to have expected a reply in between :-) . Looking at the other video now.. I would really like to make on of these if I find a cheap enough galvos..what kind of KPPS are yours
Though what about using a laser projector? They seem to be the same price or even cheaper than a Galvo kit and would have everything ou need already in a nice box. Some are even RGB for £60. As they aren't generally programamble. I guess it would require hacking to see if the signals to the galvos could be intercepted with those from the ESP. But doable I bet.
I had trouble to understand this video. Are the contact brushes still being used for some reason? Or was this just about using the same knob and overall design, but with a magnet and magnetic sensor? I'm new to this, so only read how this normally works, I'll look into a video next.
I've made an encoder from a hard drive motor but never did anything with it, I'll wait until my programming skills improve ! neat video and yeah make it wireless...cheers.
@@atomic14 Hi, I got the idea from Greatscott, it just uses the motor and the disk mechanically then comparato'rs and Schmidt triggers to get a clean pulse from the three phases, and the rest handled by an Arduino. I had it control an LED ring, so as I turned the motor the LED tracked it..great fun..maybe you could have a go and see if it would be suitable for your Asteroids ?..great work and cheers !
If a magnetic sensor - there's a magnet in attached to the shaft of the encoder and the magnetic sensor IC can measure very accurately the orientation of that magnet.
I don't know why youtube recommends me this, but once I stopped by, just fyi: the ENC35 encoder from US Digital has 60,000 pulses, so if you put a ballscrew with 4mm displacement you are going to have 66 nanometer precision. Only 200 bucks.
It's a frustrating and rewarding hobby. Not sure where the balance is though, can be extremely frustrating when it doesn't work... But it does open up a whole world of fun things.
Yes, definitely. Though I might consider using the I2C version as I had to mess around a bit to get it working consistently using ESP-IDF instead of Arduino. I think the timings on the SPI interface might be off, but I'm not sure exactly why.

Another quick question- how expensive are those rotary IC chips? I presume they're an internal arrangement of hall-effect sensors?
