Initially, Home Security Interface is in idle state. When a person approaches the device, it will be activated. This is achieved using an Ultrasonic Sensor. HC-SR04 Ultrasonic Distance Sensor is able to measure distances from 2cm to 400cm. Ultrasonic...
Rapid circuit prototype with a 3D printer and conductive filament. This project features a simple circuit designed to explain the working and use of a 555 timer IC. The connection used is credited to this blog LED Flasher Circuit The 555 timer was...
How I can use the datalogger:In the case from the data logger a switch is inserted to connect the accumulators with the Gnublin.After switching on, Linux launsch, the programms dmm and my_shutdown.Dmm reads the data of the digital multimeter, and stores...
What is Cloud Storage OwnCloud set on Raspberry Pi can be a good example of smart cloud storage. A cloud storage is a cloud computing model in which the data is stored on remote servers and maintained by a cloud storage service provider. This allows...
In addition, PEMF therapy improves sleep, mental focus, and the body’s overall performance by helping the energy output and regeneration of the body’s cells. Clinical studies have demonstrated that PEMFs are capable of: Increasing...
This is just a little pass-time project that I finished a few weeks ago. It is a restoration project for the 4SLC2-50 Laptop sold in '93. I did the routine upgrades to the unit, 8mb ram, 500mb HDD (the largest it can take) and a 387SX FPU 16-25MHz Co-Processor....
OverviewHummingbird is a hardware scheme designed to interface with a free VivaPlanet (http://www.vivaplanet.io/) data-analysis engine. Hummingbird will send information about the health of it's environment to the VivaPlanet data-analysis engine to allow...
Refactorization using new technology. I have recently acquired and learned how to use (to some degree of success) a Prusa i3 Rep-Rap printer so I have been working on making something similar to my other builds except actually wearable. This is a more...
Server-Client architecture is a network architecture which separates devices and application programs into two categories clients and servers to better employ available computing resources and share data processing loads. Initially, client uses the network...

The PIC32MX250F128B has a myriad of peripheral features that makes this cheap little 28-pin 32-bit microcontroller extremely powerful. However, it does lack a digital-to-analog converter (DAC). A simple approach to digital-to-analog conversion is to...
Story My goal was to trigger disco lights when a person or dog is detected and if a person is detected to play "staying alive". If a dog is detected to play "Who let the dogs out?" Smart disco lights This project is designed as a test application for...
Hexo, a play on hexa- as in the prefix for "having six", is a circuit that uses a 555 and CD4017 to randomly illuminate select one of six LEDs, similar to a die. By using a capacitor and transistor, the circuit will toggle through the six LEDs, flashing...
