    Kino Wheels Gives You A Hand Learning Camera Operation
    https://hackaday.com/2023/03/28/kino-wheels-gives-you-a-hand-learning-camera-operation/

    Getting the hang of camera controls is the idea behind [Cadrage]’s Kino Wheels open-source handwheels. The business end of Kino Wheels is a pair of DIN 950 140mm spoked handwheels — because of course there’s a DIN standard for handwheels. The handwheels are supported by sturdy pillow block bearings and attached to 600 pulse/rev rotary encoders, which are read by an Arduino Mega 2560. The handwheels are mounted orthogonal to each other in a suitable enclosure; the Pelican-style case shown in the build instructions seems like a perfect choice, but it really could be just about anything.

    Use your Arduino and ESP32/ESP8266 from your Smartphone. No Cloud! (RemoteXY)
    https://www.youtube.com/watch?v=dyEnOyQS1w8

    We all love Microcontrollers and Smartphones. Unfortunately, they do not work well together because not everybody can create Smartphone apps and connect them via Bluetooth or Wi-Fi to an ESP32. Arduinos are even more complicated because they do not offer communication. This is why I like the project I will show you today: Its name is RemoteXY. Of course, it uses the Arduino IDE!

    https://www.youtube.com/watch?v=EZPHcaaF7lA

    This is a RPM calculating device that you can easily make using Arduino uno and IR sensor.

    →Requirements- Arduino (Uno/Nano), i2C LCD display, i2C LCD Module, Breadboard (not necessary), jumper wires(Both ends are male pin in my case) and any rotating object for speed testing.

    →Procedure- Upload the code to your Arduino Board using Arduino software by connecting to PC then connect as per the video.

    →Note- Improper connection may damage your board so be careful !!!

    Mail your code to my microcontroller and see what happens via webcam.
    One hardware setup for many students, availability: Worldwide 24/7

    All you need to teach or study how to write code for a microcontroller is:
    1.) A computer that can be used to write and save simple text files
    2.) A microcontroller.

    Wait! Instead of buying a microcontroller, you can use mine even though I live thousands of miles away. All you have to do is:

    1.) Mail the text file with your code to my server
    2.) Wait until the resulting video appears automatically on my server’s page.

    The project teaches old technologies new tricks to teach new students how to do coding.

    Details

    My setup is as follows:

    An Arduino UNO (could be any microcontroller that can be programmed via command line tools) is connected to a Raspberry Pi (could be any computer running a Debian based Linux).

    The Raspberry Pi looks for new mail in fixed intervals (2 minutes or so) with “fetchmail”.

    If an Email with an attached *.ino file is detected, the attachment is compiled and the resulting hex file is uploaded to the Arduino UNO.

    In parallel with uploading the code, a webcam is started.

    After a given interval (1min), the recording it stopped and the resulting video file is stored on the Raspberry Pi

    The Raspberry Pi connects to my Internet server to upload the video file, the original code file and the updated webpage.

    Done!

    On the website you can now (process takes about 5 to 10 minutes) watch what your code does on my Arduino UNO.

    Uno Plus+
    An Arduino UNO Compatible Board with isolated Glowing headers and some Extras
    https://hackaday.io/project/189785-uno-plus

    Description
    If its not broken don’t fix it, just add some more features.

    The Uno Plus+ is An Arduino Uno Compatible Board with a twist. All the components are on the bottom giving ample space to clearly label all the pins and even label the second and third function.

    The Goal of the Uno Plus+ it to take the Arduino Uno, and make it even easier to use. An by adding isolated LED indicators on the IO Pins Debugging and Teaching can be even easier for teachers and student in the STEM Field. With the addition of a Stemma/Quiic connector and an integrated addressable LED can speed the process of developing a Project.

    An as always this project is completely open source and all design files will be updated to the most current revision below. You can build your own Arduino comparable Uno+ and flash the Firmware with the instructions below.

    Arduino-Powered Missile System Uses Ultrasound To Aim
    https://hackaday.com/2023/06/13/arduino-powered-missile-system-uses-ultrasound-to-aim/

    In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting for an altogether simpler desktop fire control solution.

    This fun build uses a common off-the-shelf USB “missile launcher” that fires foam darts.

    The Remoteduino Nano Is A Tiny IR Remote That’s Truly Universal
    https://hackaday.com/2023/06/18/the-remoteduino-nano-is-a-tiny-ir-remote-thats-truly-universal/

    Universal remotes are extremely convenient if they work correctly. But setting them up can be quite a hassle: often, you need to browse through long lists of TV models, key in the codes on the remote with just a blinking LED as confirmation, and then pray that the manufacturer included the correct codes for all your equipment. IR isn’t a very complicated technology, however, so it’s perfectly possible to roll your own universal remote, as [sjm4306] shows in his latest project, the Remoteduino Nano. It’s a fully programmable IR remote that gives you maximum flexibility when emulating the codes for those obscure A/V systems scattered around your home.

    The remote runs on an ATmega328p in a tiny QFN package, which drives a standard 5 mm IR LED through a transistor. Eight buttons are available to the user, which can be freely mapped to any desired code. A five-pin header is included to program the ATmega through its serial port. However, this was mainly done to help debug – a user who only needs to program the device once would typically use a pogo-pin-based adapter instead.
