DJ Mixer featuring 4Duino-24

The 4Duino DJ Mixer is a fun and interactive project similar to a keyboard MIDI Controller that has the ability to play sample beats and songs. Before, DJ and music artist needs to use computers, recording and playback devices before they can mix and play their own customized music. But using this project, the user can utilize the 4Duino LCD screens and the 4D SOMO-II music module. The 4Duino will serve as ...

WiFi Temperature Sensor featuring 4Duino-24

In this project we will quickly create a ‘temperature monitor’ that measures the ambient temperature of a room or an outdoor space. The temperature is measured by TMP35 temperature sensor and is displayed on the 4Duino screen. The data is also sent to Thingspeak IoT platform which enables data logging over a period of time. How it works Components 4Duino TMP 35 Temperature sensor Bread Board Jumper cables µ ...

Dead Simple Ultrasonic Data Communication

Some of the best hacks are the ones which seem perfectly obvious in hindsight; a solution to the problem that’s so elegant, you wonder how it never occurred to you before. Of course we also love the hacks that are so complex your eyes start to water, but it’s nice to have a balance. This one, sent in by [Eduardo Zola] is definitely in the former group. In the video after the break, [Eduardo] demonstrates hi ...

BeagleBone Logic Analyzer

Since I started this adventure in hardware I have wanted to get an logic analyzer. I have an older but good oscilloscope that only goes so far when it comes to digital logic signals. I could go for the Saleae, but if I am going to do that I would rather sprint for the higher end model which is an easy $400+. In the mean time I was on a quest to find a low cost option. Upon my travels of the interwebs I foun ...

MKR1000 Temp and Humidity Sensor

Send temperature and humidity data from an Arduino MKR1000 to Microsoft Azure. Things used in this project Story Paul DeCarlo has a great article on sending weather data from a Particle Photon to Microsoft Azure. I wanted to duplicate this with the new Arduino MKR1000. The Photon uses a webhook to send data from the Particle cloud to Azure. Since the MKR1000 supports HTTPS, data can be sent directly to Azur ...

AmpStrike – Battery Powered Bench Power Supply

Introduction This is a small bench power supply that is powered by two lithium-ion batteries. The project was inspired by Dave Jones from EEVblog but the design is completely mine. The voltage range is 0-20V regulated in 10mV steps and maximum current is 1A with current limit set in 1mA steps. Schematic Linear Voltage Regulator The power supply runs on a linear voltage regulator built on discrete components ...
