Bruno Gavand build a simple metal detector using PIC12F683. He writes: The idea of this circuit is to hack PIC oscillator circuit, by replacing the crystal by a coil : the frequency of the oscillator then depends on presence of metal near the coil, just like in a classic metal...

Jakub Polonský created this solution to make breadboard prototyping safer for components: adjustable and programmable electronic fuse especially designed for breadboards – a breadboard fuse, or BFuse BFuse: Electronic Fuse for Breadboard -...

"pinko" has designed a simple datalogger based on a PIC microcontroller that logs data on a SD Card. He writes: Some time ago I decoded to make a simple general purpose Data Logger with the following parameters for the project. it should have very simple design that should be...

pickandplace.wordpress.com writes: I started with making the TMP102 temperature sensor work. Nothing to say in particular, it’s just an other I2C-small-package-sensor. Or rather SMBus, but apart from the minimum speed clock requirements on the SMBus, the two protocols are...

Sarunas built this device to replace a bunch of different remote controls with a smart phone. Controlling TV, HiFi, DLP and similar IR controllable stuff is easy and fun from a smart phone using previously built smart remote, until it runs out of battery. Despite that Bluetooth Low...

Ambiq Micro, the leader in ultra-low power solutions, launched  the Apollo 2 Wearables and IoT Platform. The Platform offers breakthrough power consumption of under 10 μA/MHz, which allows for double the battery life in wearable devices. Apollo 2’s performance will lead to longer...

Today I am going to discuss how to make a very simple DIY Breathalyzer using Arduino UNO and few external components. Ana Carolina designed this project as an instructable in instructables.com. This is a low-cost project and a useful one too. If you have no idea about what...

Matthias created a X-Mas tree project using the DirtyPCB boards from dangerousprotorypes.com : The project features an USB capable PIC16F1549 µC with: USB FS device 48 MHz internal Oscillator 2 PWM modules 10-bit ADC with Voltage Reference Integrated Temperature...
