One thing not mentioned here (and it's a little-known but potentially very useful feature) is that in addition to the standard HID descriptors and profiles for things like keyboards/mice/joysticks, it's also possible to set up a "custom" vendor-specific HID descriptor that doesn't map to one of the usual classes. The device will be detected by your PC automatically and be accessible to applications, but the operating system won't do anything with it by default. This allows you to make "driverless" custom USB peripherals with their own data-exchange requirements. You basically set up the HID descriptor to contain generic read/write data blocks that match your use-case, and you can then interact with these blocks of data from the connected host. You need to write the program on the host side to interact with it (so it's more work than piggybacking on a standard class), but it's orders of magnitude simpler than writing a custom driver from scratch and sidesteps all the painful signing requirements that normally entails. Controlling custom RGB/LED layouts or LCDs, custom sensor inputs (force, temperature, accelerometers, etc) and more are all possible using this approach, and you don't have to worry about other applications interfering with your peripheral or ensuring you're not going to affect other programs because of some fake keyboard inputs you're sending. I believe it's even possible to interact with such custom HID peripherals directly from the Chrome web browser (because it has some APIs for interacting with USB/HID, although other browsers don't support this) although I haven't played around with this myself.
With this Method i've bult a foot pedal used as PTT e.g. for discord. TIPP: Use funktionkeys F13 to F24, since they typically are not used by any standard input scheme, because this keys don't exist on a standard keyboard. But emulated with an arduino they work like a charm.. Great for Programs running in the background.
The jog wheel should have some kind of indexing mechanism in it that snaps into grooves on a wheel or something similar. Open the thing, remove (or break) this, add a good amount of non-conductive grease (for dampening) and you should be done. Thanks for this informative video :)
I had some hoby projects in the past year, that ended up beeing HID devices. Maybe some inspiration for others: 1. some inputs for flight simulation at my PC. Here I used a Teensy. First I only added some Buttons and switches and a rotary encoder (to set the radio in the plane). When my rudder paddle device broke I did build an own that is also run by the very same Teensy-module. 2. A friend needed to combine two HIDs to act as one (with some tricks to avoid interference of both). I chosed a maybe overcomplicated solution with a Rasperry Pi where I plugged in both HID-devices. A Python script was able so separate inputs from both HIDs and ensured proper order... this was send via serial port to an arduino, which worked as a HID for a PC. 3. control TH-cam player on Smartphone or iPad. A musician want to play along YT-Videos... a ESP32 emolates a mouse/keboard HID and enable to chose a specific video with a rotary encoder. This video is then started in YT-app. An extra button trigger to jump at a specific time in the video. Raspberry pi Pico can also be used as USB hid. If you build a Bluetooth HID, don't forget to add a battery information (read voltage with analog pin). Battery status can be send via bluetooth, this is part of HID-protocol.
Also of help might be "Autohotkey" which can act as a layer above the HID and is able to run entire Macros. This can also detect & change which window is in focus, so can be made robust to input interruption. This is a lot easier to write & debug. Plus the microcontroller is simpler as it only has to send one keystroke combination (which can be entirely novel control+alt+whatever you like) for each action and AHK handles the rest.
ah its a replay. Still I got one of these videos for once within a year of it being produced. Keep it up - you have no idea just how much all these videos are helping I just deployed my first solar-powered esp32 project using a tp5000 and a lifepo4 battery and your vids were like 95% of what I needed from the hardware side.
I find the ducky device often called a digispark. I made some devices to tap the ctrl key every 5 minutes for some friends to use on their work devices and keep them awake.
I built some digispark duckies, if you want to keep a computer awake you just need to draw a one pixel square with the mouse every few minutes, unless you're doing graphics or something you'll never even notice.
The "Digisparks" are not 32U4-based though, and they don't actually have USB either - they barely limp by as a low-speed USB1.1 device, bitbang-emulating one with a rather shoddy timing.
A standard through hole or panel mount rotary encoder with a big heavy knob attached should run pretty free. I put one on a panel for some equipment at work, it has a little finger detent and you can give it a quick spin to make big changes or dial it in exactly, it's so much better than buttons.
I used an attiny85 on a board that fit in the usb port. The program pressed caps-lock at random times. Drove my co workes crazy when they couldnt figure out the problems with their keyboards 😂
AH, this is a cool video. Why did I not notice this before? I have been playing with USB keyboard interfaces a lot and I also have been working on a similar jog wheel for Davinci Resolve. I used an AS5600 magnetic angle sensor, a large bearing and some 3D printing to create my own jog wheel. That works great, the only problem I had was most microcontrollers only implemented a slow speed USB which uses a 8 ms polling rate, resulting in max. 62 keys/s. I used a Teensy 4 to get full speed USB with a 1 ms polling rate, theoretically getting up to 500 keys/s. This completely removed any key lagging in my case. I cound the AS5600 a great solution for this since this now allows me to adjust the number of steps (keys) per rotation, resulting in a perfect 1, 2 or 5 second (25, 50, 250 or 30, 60, 300 pulses) step per rotation. I not have to check if the ESP32 is up to a similar task so I can replace the umbilical (USB) with a battery to get more freedom on my desk😀
What microscope camera setup are you using there? Ive been looking to get one like that, but there are so many different models that look the same but with vastly different specs...
7:50 you should talk to Tinkering with Atkalar. He services switches and may be able to help you removing the brake function. He is from Wien in Österreich.
I have a similar looking microscope, and didn't like the mouse control, but i found out that plugging a usb keypad instead of the mouse give me the most used commands. You can choose focus mode manual/auto, when in manual focus you can adjust it with two keys or make a single shot automatic focus. And you can make a screen capture. The only function i miss is starting/stopping vidéo capture.
Yes lesson learned when seeing hello world all over the Arduino ide. Lucky for me, it was a Leonardo there has a reset to hold it, so it could be reprogrammed.
As a rotary replacement, what about a stepper motor (from a printer or something else)? But I do not know how to detect the direction for that 😞 PS; for a project I would like to do, do you know if there is an ESP library to connect to an external HID over bluetooth? I have a scanner which can behave like a keyboard either over USB or BT. Of course I also have other solutions which already support usb IN, and I wil use that alternatively. But if there is an ESP library for this, that would be great! Second question: I would like to remote control lights and such. But all the radio or LED controlled devices use 5 mA at standby. This is way too much. I know BT used really so little, I would like to enable lights over BT with a simple BT switch (those ones they sell for taking pictures with your Android). I am asking too much. But I hope I may inspire you to use either one for a project (if you know there is a working solution). PS: yes, I have seen most of your remote devices in many of your previous videos! Do know I watched them all. I was just thinking of switching a new way. Or: do you think a BT receiver would use a lot of power as well? I do know the sender uses almost nothing! I have temperature meters running all day on a cr2032 battery for over a year. BT must be the way to go I think.
Unfortunately, bluetooth on the ESP32 was quite power-hungry when I tried it. So it is not an ideals platform to save energy... Otherwise, BT is great!
@@AndreasSpiess Thanks! I will focus on radio signals. An AM radio needs as good as no power (the sender is the source). Keep up the good articles on your channel, I like it. It is unique in its kind.
A pain in the dah-dah-dah to program? That's a pain in the O. Surely you meant it's a pain in the dit-dah-dit (dit dit dit) - that's a pain in the Rs ;-)
It should be possible to modify the CNC rotary encoder you show. I have done it with one (for tuning an SDR). I had to remove the 'handle', carefully remove the centre disc (it's stuck on with double-sided tape), remove the knob then remove the spring-loaded ball-bearing which creates the 'steps'. I got this information from another YT channel - can't emember which unfortunately.
Andreas, for the encoder I just use a standard encoder like we use in industrial applications you can get them cheap. then I buy a solid aluminum knob usually a large diameter with a 6mm hole for the encoder. I also use these on my radio builds for frequency tuning. it works great and the weight of the large aluminum knob works very smoothly.
@@AndreasSpiess 600P version of either is more than enough count per rev. you could probably go lower but you can fix it in code. The first encoders I used are this one $9.36 US: 100/200/360/400/500/600P/R Photoelectric Incremental Rotary Encoder 5V-24V I found a cheaper one but didn't try yet $6.26 US New incremental photoelectric rotary encoder 400P/R 600P/R 360P/R pulse / line AB two-phase 5-24V NPN PNP output 2m cable The knob I prefer the larger one here $12.50 US: 1pcs high quality aluminum knob solid potentiometer knob 44*22*6m But smaller knobs work also 2pcs for $2.53 US: 2PCS Aluminum Solid-core Knob Cap Size 32*13mm 13X32MM The Inn Have fun with this, it makes your project seem much more impressive with the feel you get. it's like using a store-bought radio. and thanks for all the videos.
@@AndreasSpiess By the way, let me know if you need more info maybe I can send the links a different way. the schematic was a standard easy-to-find version. it will bring your input to 0VDC and there is a better schematic that has just a little filtering in it I haven't tried to use that one yet but it could be even smoother.
@@AndreasSpiess Oh nice! you are going to love that setup! the only thing we may have to come up with is an adjuster to put some friction on the knob so it doesn't over travel but it works so well I just let that go. I'm happy to see you found them. can't wait to see them in a video.
So did anyone since found outwhat BLE input device commands android stuff understand for next, prev, pause, etc.? (it is asked in the video) - but it reminded me that i never found out how to do it years ago, and the real actually fully working solution to the problem i wanted to solved years ago, still does not exist. (aftermarket car head unit :D )
Interesting, this solution might help me build physical knobs for my Analog Discovery 2, a software oscilloscope. Hope your summer will also be nice, greetings from Sweden.
A friend of mine had a horrible accident and was paralyzed from the neck down. I used an ESP32 to built him some buttons and levers he could actuate by moving his head. One function was launching the Google assistant reliably instead of "ok Google", which get frustrating quite quickly.
I didn't know I wanted this before but now is like a rotary encoder on my phone and computer for moving thru yt videos. I wonder if the same left/right key strokes will work on Android yt as in my desktop browser.
challenge - is it possible to connect a USB keyboard and mouse to Arduino at the same time? Esp32-s3 with USB-OTG currently supports only one connected device at the same time.. Any suggestions?
Hey Andreas! Great video, as always. I've been looking for something like this for some time, but for controlling my music production/live mixing, and usually those programs use the MIDI protocol - maybe it is worth a try on exploring it? Many musicians use very expensive controllers that could be done for basic functions with little less than some buttons and a controller board. Another thing I've been trying to explore, but with no success, is doing a DIY button matrix, where each button could be illuminated with a defined colour (e.g. to dynamically allocate functions to them and know what they do in each program by their colour), it seems that it is a bit difficult to build RGB buttons, maybe you have any tips on that?
You should find projects for small keyboards with different additional functions. An may use ready-made "Stream Decks". So far I had no use for midi (other than for a video on my second channel).
Cool video! I wanted to make a macro keyboard for myself, maybe that's a sign to finally do that. PS: For a smartphone photobooth - it works with headphones' buttons (wired or wireless) as their buttons also take a picture. I used to have a lot of old broken earphones with working buttons, before moving.
@@AndreasSpiess I can't remember where I saw it. I used adafruits rotary encoder board to read the pulses from the magnets though. Used it for the same purpose as your thinking. It also looks cooler because it's shiny. They're also all over the place and I'm sure you have many old ones.
Would probably be possible if you know what vband expect. Maybe a simple serial adapter would be sufficient. I made once a video about a similar thing on my second channel.
There are Chinese encoders available with very smooth movement and a standard 6mm shaft, just add a machined knob that has some decent mass to give some inertia.
I have used an Arduino Micro as a game controller in order to use a sled as a car driving device (I also made a video showing that). The possibilities with this device are so huge!
Since this is a replay, the camera I used is no more available. It uses a SONY IMX290 autofocus sensor. I now posted a link to a camera with a newer sensor.
@@AndreasSpiess That was 7 years ago, this looks like it's new and you are using a stand-alone lens. The reason why I ask is that you get pretty good image quality, the one I got from AliExpress is lousy so I'm looking for one that is decent and affordable. The alternative is to convert a DSLR into a microscope.
@@AndreasSpiess oh for many reasons. But it seems everyone disagrees with me. For one, is it an RF transceiver or a microcontroller? Another point, they seem to take so much feedback from the hobbiest community as from the Arduino but when they give you the option to use their ide with the idf they end up with half functional code that doesn't run the same firmware between updates. Dear Andreas, you're a model engineer, what do you think? Please share.
I wait when the first USB-C rubber ducky with video capture support comes out. A nightmare for security. With a OCR or a nano AI model he can control the whole computer.

I agree.
You could use a hard drive, a spinner, to create a freely moving rotary encoder.

There are Chinese encoders available with very smooth movement and a standard 6mm shaft, just add a machined knob that has some decent mass to give some inertia.
Thank you for the additional info!
7:09 Evan Kale 😢 I miss this guy. He got me into tinkering with electronics. Wish he’s all good
Success on TH-cam is not easy for young people, I think.
Maybe a projet that manages password with face or fingerprint for easy input on challenngingn apps?
That's a big risk if you lose the device 😕
please make a video on sct013 100A/50ma and ads1115 for calculate ac current
I made some videos about such topics.
Super sonntig mit Andreas films
Danke!
I have used an Arduino Micro as a game controller in order to use a sled as a car driving device (I also made a video showing that).
The possibilities with this device are so huge!
Cool project! But I do not know if your daughter liked it that she had no sled afterwards ;-)
@@AndreasSpiess good question, I was too busy playing to ask her!
Thanks for watching ;-)
interesting 👍
Glad you think so!
High quality jog wheel: maybe slaughter a disused Logitech mouse for one?
Maybe. I never tried...
Yes and mod it in a nice box
I saw a build where they used a VCR motor as a jog wheel!
Cool idea!
Well, left some comment about my 3D printed job version / project.... Any mention to external links get zapped.... Too bad.
It kind of sucks that we cant share info on such a topic, makes the whole comment section sort of useless.
What are you talking about?
Indeed, TH-cam deletes most comments with links.
@@AndreasSpiess I sent you some pictures of the 3D printed encoder on X.
@@SarahKchannel Thanks. I will check later.
Esp32 ble keyboard have lags issue.
Thank you for the info. I was not aware.
hi Andreas , nice video, how aobut some proyect of old HF transmitters and recivers for amateur radio aficionados?
At the Swiss Radio Amateur Society (USKA), I am responsible for "new technologies". You you should not expect too much content about old radios ;-)
@@AndreasSpiess i así because you know a lot
Ask
Can you link that scope-camera? It looks awesome
Since this is a replay, the camera I used is no more available. It uses a SONY IMX290 autofocus sensor. I now posted a link to a camera with a newer sensor.
@@AndreasSpiess Thank you!
Bedankt
Thank you for your support!
:-)
Use optical encoder for smoothness
Good idea!
Still a good video, thanks!
My pleasure!
What is the model of your microscope? Where did you buy it?
I did not find a link, but added one of its successor.
@@AndreasSpiess Thanks, do you know the sensor of your microscope?
@@ergindemir7366 SONY IMX290
Cool! I wish someone would just make these devices.
Maybe you find one on one of these project pages?
@@AndreasSpiess Good point. Still, it will be nice when they are more mainstream. Thanks for the vids!
Would love to see the review of that microscope.
I once made a video about microscopes. But mainly optical binoculars. If you watch it, you will see why...
@@AndreasSpiess That was 7 years ago, this looks like it's new and you are using a stand-alone lens. The reason why I ask is that you get pretty good image quality, the one I got from AliExpress is lousy so I'm looking for one that is decent and affordable. The alternative is to convert a DSLR into a microscope.
@@galileo_rs I bought the new one because I never managed to get the camera working on the trinocular. I just have it for TH-cam.
Thank you
You are welcome!
Thank you.
You are welcome!
Esp, a confused chip.
Why do you think?
@@AndreasSpiess oh for many reasons. But it seems everyone disagrees with me. For one, is it an RF transceiver or a microcontroller? Another point, they seem to take so much feedback from the hobbiest community as from the Arduino but when they give you the option to use their ide with the idf they end up with half functional code that doesn't run the same firmware between updates. Dear Andreas, you're a model engineer, what do you think? Please share.
@@xDR1TeK I like the possibilities of the ESP32 and did many projects with it. Its price performance is excellent, and its community support, too.
I wait when the first USB-C rubber ducky with video capture support comes out. A nightmare for security. With a OCR or a nano AI model he can control the whole computer.
We need a tutorial how to create a cheap powerbank in 2024
We get now very good USB-C powerbanks for cheap. So I most probably would no more build my own...
