Escape Room Decoder Box
Escape Rooms are awesomely fun activities which are highly engaging and great for teamwork.

Have you ever thought about creating your own Escape Room? Well with this decoder box you can be well on your way! Even better have you thought about using escape rooms in education? We have and students love using them to learn, revise and engage with the material.

Weather Based Music Generator (ESP8266 Based Midi Generator)
I'll explain how to make your own little Weather-based Music generator.

It's based on an ESP8266, which is kind of like an Arduino, and it responds to temperature, rain and light intensity.

Don't expect it to make entire songs or chord progressions. It's more like Generative Music people sometimes make with Modular Synthesizers. But it's a little less random then, it does stick to certain Scales for instance.

Челябинск - самый мемоёмкий город в мире по мнению Юрия Дудя! Хочешь узнать почему? На этом канале ты найдешь ответ на свои вопросы. Как уже второму по счёту губернатору удаётся сбежать с миллиардами в Лондон? Почему Челябинск заслужил звание города в состоянии экологического бедствия? Как губернатор Текслер стал инстраграм-звездой? Когда на город упадёт еще один метеорит? Почему тут живут самые суровые мужики? Челябинск - город который СМОГ! https://t.me/chel_ned

Arduino Magnetometer
What are we building?
Humans can't detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic field vector at a location is displayed on a small screen using isometric projection.

How to Make a Self-Watering IoT Planter With a Mason Jar and an ESP32!
This project has a long list of Tools and Materials. Because of this, I've divided the list into sections so you can see what materials are required, depending on the part of the project you are building. I've also provided Amazon links to each product, so you can easily find the parts you need.

DIY Geiger Counter With an ESP8266 and a Touchscreen
I designed and built a Geiger Counter - a device that can detect ionizing radiation and warn its user of dangerous ambient radiation levels with the all-too-familiar clicking noise. It can also be used when scouting for minerals to see if the rock you found has Uranium Ore in it!

There are many existing kits and tutorials available online to make your own Geiger Counter, but I wanted to make one that is unique - I designed a GUI display with touch controls so the information is displayed in a pretty way.

Flsun 3D Printer / High Precision / Large printing size 260*260*350mm / 3d-Printer Kit / Hot Bed / One Roll Filament / Sd Card
The printer works great after assembly. Defaults in firmware are correct for motor directions so check motor and limit switches are connected correctly, paired if issues. Need to load Arduino to a PC, adjust extruder steps. Use repetier host and make a mark on filament by extruder motor, drive back 100mm in repetier (manual, extruder axis) and measure. Divide this number in mm by 100(expected) and in Marlin configuration file, search on "steps" and find the extruder steps parameter. Multiply it by your above result and amend the file. Be sure to also calculate autolevel z probe sense offset and load to Marlin, fix Marlin probe_bed_position back and right values (250 recommended) Download. Run home then G29 command to autolevel again, it should spread over more of the board's span.

How to Setup Fingerprint Sensor With Arduino
The fingerprint sensor we are using is an Optical Type, there exists two more types of sensor like capacitive which can be found in smart phones and ultrasonic ones, which are yet in testing phase, and both these options are expensive, so we will focus on this optical type for this hobby electronics and similar projects.
