As always, a very inspiring video. I have recently made an ESP32 based 20 key keypad to control my OBS stream. It was your ESP32 videos that pointed me into the right direction.

[@codigoBinario01]

Seeing this working would be really interesting for me, since I use OBS for teaching purposes (avoiding post-production due to time limitations)

[@MarionMakarewicz]

@@codigoBinario01 I used cherry keyboard switches for my build. I have a laser cutter and engraver which helped to make the key placement exact, but a 3D printer couild do the same. I only had to purchase the diodes, the keys, and the ESP32. It's a pretty easy soldering job. the software is dead simple to adapt to your needs. I used Brian Lough's KZbin videos on making a keypad to guide me and adapted his software with just a few changes. My first major electronic project. His is dead simple and can use one of those flat blister 12 figure flat plastic keypads. The other route is to get a bluetooth USB number keypad. Then you can make it more easily wireless which is very handy to step away from streaming computer. You can also reprogram that keypad too. Right now I am trying to figure out how to use LiFePo batteries with this and get a rechanging circuit built in to mine.

Great video as always. I just used a Joystick library on an Micro Pro to connect a Clutch Pedal that I am using in my Sim Racing, the pedal is also self made by using a potentiometer.

Thank you. You too!

[@sharedinventions]

I would recommend you to use USB HID Touch device emulation instead of mouse (if it is possible in the driver you use), as it operates on absolute positions instead of relative movements. Also note, that HID keyboard will still just send "key IDs", this it is effected by the active keyboard layout of your operating system.

[@AndreasSpiess]

For PCs this is a much better idea. However, this software runs on the camera and it probably only understands "mouse"

[@abandonedcranium6592]

What if I want to create a HID device that does not "mimic" an existing mouse or keyboard? I want an analog input added to my computer, but I need it to be a unique device. Would I have to create some kind of custom drivers to make that possible?

Well after looking at your website it seems that KZbin comments are the best way to reach you. I merely want to thank you so much for all the great content you have been putting out here on your channel. Though I have been messing with computers since the early 1980's, I have always only been comfortable with software. Of course I can build computers from parts, etc. But having never had a proper electronics education, I have always had some trepidation when it came to discreet electronic components and other things that involved soldering irons, blue smoke, and (seeming) black magic. But recently I have discovered the world of NodeMCU devices and decided that I should buy a soldering iron because maybe it was time to play in the hardware hacking world. Shortly after learning how to make a fun LED-strip project with a NodeMCU, logic level converter, and buck-converter, I came upon your channel here on KZbin. I find all your videos extremely informative and fun to watch,. And they give me inspiration for future project ideas. I really especially appreciate your videos on antennas, as I have found them fascinating. I have watched many of your videos now and enjoy them very much (including the summaries at the end, by the way -- I don't skip the endings). I just want you to know that you are appreciated. So thank, you, Andreas, for all your hard work, and your fantastic presentation.

Not that I have any certainty of that model, but it is sometimes possible to remove or bend the latches that stop the encoder from moving freely on #3. Then you might want to add more weight hidden in the wheel so it has more inertia. Great video!

Just to remark: HID Devices are a pain, if you need to route / filter keypresses to a special application. This is such a pain. There is no simple API/OS Funktion in Windows to detect which HID Device has sent the keypress. Simple to do Linux, but not in Windows. I run into this problem to build a special communication keyboard which only should send it's keypresses only to one application. There are some solutions with LUA and some Macrorecorders e.g. Auto Hot Key. A painful solution. This is the horror, when you run a multi screen environment and you like to have a special console for one app and a normal keyboard for the main screen. I build a in flight control system for quadcopters and I need 2 application which both have the same mapping of shortcuts and they do not have a configuration to change this. Final solution: One of the apps are available in linux so i run a small virtual container in seamless mode and filter the forwarded keypresses via UDEV Rules. Works well, but was a long way to build a field stable application.

[@AndreasSpiess]

You are right. The focus is always important for my examples. I read that they were able to program "invisible" injections. So they were somehow capably to do it. But I do not know how. Your solution seems to work.

I work with rather closed software that relies on very very slow mouse inputs, a few key combinations, and best yet command line for efficient inputs without (easily) misclicking on stuff.

HID is a place where CircuitPython can be a lot of fun and save time in the developpement. Take any M0 (or M4) CircuitPython board, even a Gemma or Trinked M0 and you are ready to inject USB key/mouse/media button. If you want some BLE fun, you can use any nRF52840 board and do that too (and simultaneously USB and BLE HID). I would go for the ItsyBitsy family if size matter. My usage has been to keep the computer/VDI connection alive while teleworking, jiggling the mouse in tiny circlar motion (octogonal move really) is enough to keep it alive but not disturbing for the user.

Sorry for ma wrong answer. I only saw the *ESP32 wireless" and somehow omitted the rest. Cool idea of Greatscott!

[@p_mouse8676]

It's actually not so difficult to bit-bang USB with other microcontrollers. For example an ATTINY85, can be used as well.

[@AndreasSpiess]

True. But the price differences are no more this big, I think.

[@p_mouse8676]

@@AndreasSpiess it depends if you just buy an arduino type board, or make your own PCB. Or when there is only a limited amount of space.

Interesting video... Just wonder that changing(DIYing) bluetooth 3.0 device to 5.0 is possible or not.

[@AndreasSpiess]

I do not think so.

Link for microscope doesn't include the lens, is it standard lens or have to buy specifically for this microscope?

[@AndreasSpiess]

I thought I added two links?

[@steameier8590]

@@AndreasSpiess Yes, but in your lenses-link are several versions listed, which type did you choose? (gain-factor)

Thank you very much for your again excellent video. In this video I saw that you are using winSCP; I am not anymore. A few weeks ago I was looking for a bottleneck in a transfer of larger files. I noticed that the communication with SCP via winSCP is extremely slow. Still slow with SFTP via winSCP. SFTP via Filezilla met my expectations. Since you always allow ssh access to a device, SFTP works without additional installations. I wish everyone a nice summer :-)

[@AndreasSpiess]

Thanks for the tip. I do not use it often and only for very short scripts. So I did nor recognize it.

[@mrksaccount123]

Will miss the frequency of your videos... but I am sure it is for good reason

[@AndreasSpiess]

Thank you! It will change back in September.

@7:18 , this guy was one of my favorite project based KZbinrs especially on the topic of Bluetooth .. Wondering what happened to Evan Kale ?

[@AndreasSpiess]

I do not know. But KZbin is hard business if you want to live of it. And as a hobby it consumes a lot of time.

7:55 Great Scott made a video how to use a hhd motor as a rotary encoder. He gots preety much the same issue.

[@AndreasSpiess]

Somebody posted a link. A great video!

Great projects Thanks for sharing 👍😀

[@rjnerd]

This is helpful. Do you know if the keyboard library works with a bbc micro:bit?

[@AndreasSpiess]

I fo not know the micro bit :-(

[@rjnerd]

@@AndreasSpiess The BBC micro:bit is a small (4x5cm) board intended for educational use. Every 11 year old kid in Britain received one to use in class, starting in 2016 (over a million to date). Its based around the Nordic nRF51822 and includes bluetooth, native USB, and the thing that makes it interesting for my application, an accelerometer, two uncommitted buttons, and a 5x5 led matrix. It will even run off a pair of AA batteries, the kit includes a holder. And they are cheap, US$15, while the comparable arduino BLE nano lacks the light matrix and uncommitted buttons, for US$21. (I am trying to build a simulator for a hand bell, that could be assembled from a cheap off the shelf board, without the need for any soldering. All it would require is attaching some kind of handle, and loading software to make the thing, greatly reducing the skills needed to build yourself some. Its intended to be used with simulation software that currently just detects key presses. So I need bluetooth keyboard to press the buttons, the accelerometer to detect when you swung the bell, and the buttons/lights so you can select the note the bell will play)

[@AndreasSpiess]

Good luck with your project.

[@GlennHamblin]

Excellent! Thanks Swiss accent guy!

You're welcome!

Similar to the Rubber Ducky, there is also Bad USB, which can also come with WiFi, when an ESP8266 is added, aka WiFi Ducky.

[@AndreasSpiess]

Never heard about the WiFi version. Thanks!

For project number 4, how can i make a button stay ON if I press the button, and OFF when i release it? Its because when I try to hold the button to stay on, it only send 1 command at a time. (Its for a push to talk project).

[@AndreasSpiess]

I do not remember the details. But I assume it can be done by simple programming logic.

[@nathanielluke2084]

@@AndreasSpiess hymm, ill try to work on it on my own. Thanks 👍👍

[@nathanielluke2084]

@@AndreasSpiess i dont know how to make an input of a keypad stays on, so i decided to just use simple push buttons. So far so good, ill expand it more in the future. Heres the code: #include BleKeyboard bleKeyboard("BLE Macro Keyboard", "NATHLUKE"); const int button1 = 17; const int button2 = 16; int buttonstate1 = 0; int buttonstate2 = 0; void setup() { Serial.begin(9600); bleKeyboard.begin(); pinMode(17, INPUT_PULLUP); pinMode(16, INPUT_PULLUP); } void macrokeyhere (uint8_t key){bleKeyboard.press(key); } void loop (){ buttonstate1 = digitalRead(button1); buttonstate2 = digitalRead(button2); if (buttonstate1 == LOW){macrokeyhere(KEY_LEFT_ALT); Serial.println("Button1 is Pressed");} if (buttonstate2 == LOW){macrokeyhere(KEY_LEFT_CTRL);Serial.println("Button2 is Pressed");} else {bleKeyboard.releaseAll();} }

How about putting your laser cutter to work and make a hall effect based jog wheel?

[@AndreasSpiess]

Possible. But I have no such laser :-(

[@hermesvoeglein535]

Because it wasn't mentioned, to protect yourself from HID-KSI-attacks best approach would be to first never leave your running PC unattended and to configure your PC etc. to ask for authorization when a USB device is plugged in, regardless of the type of device, or if the device is known to your PC.

[@AndreasSpiess]

Thank you for your addition. I am not a Sysadmin, so I just do not use USB sticks I did not buy myself.
