Nick Johnson from Arachnid Labs has designed a powerful and affordable signal generator (named Tsunami) based on the Arduino platform, and is now running a Kickstarter for making it available to electronics hobbyists worldwide.
The Tsunami is a powerful and flexible signal generator built on the Arduino platform. It’s the best way to get started experimenting with analog signals, and a great tool for a huge variety of tasks, too.
The tsunami takes the versatile processor behind the Arduino Leonardo, and combines it with a Direct Digital Synthesis chip, which makes generating analog signals incredibly straightforward. It also has flexible input and output circuitry, and an easy to use software library, to make working with analog signals as easy as blinking an LED.

Most of us who have experienced 8-bit MCUs previously know how much important it is to have an Analogue-to-Digital Converter (ADC) built-in with a microcontroller. Apart from other hardware extensions unavailable in the early era microcontrollers, many former 8051 microcontroller users shifted primarily to more robust Atmel AVRs and Microchip PICs just for this important peripheral. I don’t feel it necessary to restate the advantages of having such a peripheral embedded in a micro. In traditional 8-bit MCUs aforementioned, the ADC block is somewhat incomplete and users have to work out tricky methods to solve certain problems. The ADC block of STM32 micros is one of the most advanced and sophisticated element to deal with in the entire STM32 arena. There are way too many options for this block in a STM32 micro. In this issue, we will explore this block. Read more
Hackaday has just announced their second Hackaday Prize competition today.
Hackaday Prize 2015
Last year The Hackaday Prize began a movement, this year we’re solving problems that matter to everyone. The creative energy and years of experience found in our huge community of Hackers, Designers, and Engineers is waiting to be unleashed. Let’s use that potential and move humanity forward. This doesn’t mean one giant solution. Thousands of people, each lifting one stone, moves mountains.
Martin Harizanov’s WiFi-enabled thermostat runs entirely off the ESP8266 SoC and is controlled through a touch-friendly user interface running on mobile devices. His project also has broadcasting functionality, which allows the thermostat to send data to thingspeak.com or similar platforms.

If you have any spare old phones with no use lying around, you may want to use their batteries to build this portable charger for your new smartphone. On the electronics side, this project only requires a LiPo battery charger module and a step-up voltage converter module, both of which can be bought for less than $5 on eBay.
