Piezo Alert System.
Iturriaga Aug 28,2023
Within the fast-evolving sphere of security tools and home automation, creativity often paves the way for enhancing safety and comfort. Introducing the "Unpress Alert", a nimble and efficient security alert mechanism. At its heart is the power and simplicity of the ATTiny85 microcontroller, and its mission is straightforward: alert the user when its button is released, a quintessential trait for detecting unauthorized access or movements.Disclaimer:The "Unpress Alert" system is primarily concept...

ATTiny85 Foot Pedal Controller
Hugatry Aug 28,2023
What?This is simple test circuit for reading the position of old sewing machine foot pedal (low voltage version with 3.5mm plug, not the older dimmer-style pedal). Two outputs are for controlling LEDs and Solid State Relay.CircuitCircuit is supposed to have a panel mounted 3.5mm mono jack with switched sense-pin. Usage is explained more thoroughly in the video. ATTiny85 reads the analog reading from foot pedal circuit and can read the pedal's position and detect short circuit, open circuit and u...

RLC Arduino Tester
ELECTRONOOBS Aug 25,2023
Code HereThis is a component tester made with Arduino. Is not the same as my multimeter. I mean, It still measures values but in this case it measures component values: transistors, diodes, resistors and capacitors, inductors and more. It could measure components with 3 pins and tell you different information about each component. If it is a mosfet or a BJT, its on resistance, the polarity of a diode, the capacitance of a component and so on. Later we will see some tests with different component...

I made an ARDUINO NANO Clone Board
Manoj kumar Aug 25,2023
I made a series of Arduino Atmega328 boards and every new version has something new. We always learn something by doing practice of PCB designing. And This time I tried to exactly replicate the Nano board. Previous some version has minimal components yet they all are compatible but this time the board comes with extra protection features and USB type C. Most of the bigger companies design their top product without any component’s placement hints on PCB, means no silkscreen. And this time I do ex...

RC Light & Sound controller with integrated ESC based on ESP32
Spyra Aug 23,2023
This is a remix of TheDIYGuy999's ESP32 Light & Sound Controller: https://github.com/TheDIYGuy999/Rc_Engine_Sound_ESP32.The optional ESC based on RZ7886 is now built in.I changed the passive size to 0603, bulk caps are now THT (it's what I have access to).

Sheikah Slate for Cosplay
Anthony Aug 23,2023
In November 2021 I decided to tackle my next cosplay build – Nintendo’s Zelda Breath of the Wild’s Link, specifically his Royal Guardsman armor from the Champions Ballad DLC.Sewing aside, the biggest part of the project proved to be the Sheikah slate. Initially I considered making a “dummy” prop, maybe with lights, but after doing some research I started down the Adafruit rabbit hole (thanks @ladyada) and opted to integrate a 7inch TFT touch screen, a small camera, a noisemaker, and various ligh...
