After countless hours of playing with 3Drag (now with a lower price!!) we finally selected 10 prints that you can use to explain what you can really make with your 3D printer. 3D printing is every day more often mentioned in the press: lots of stories, ranging from printing human tissues (thus saving lives) to creating…
[youtube id=”5H85RDA5HEw” width=”620″ height=”360″] Andrew O’Malley, an amazingly creative maker, created this fanstastic Open Source Arduino-based clock that can display the time in many different ways: if not enough, one can also add his own personal animation. Andrew’s idea Compared to other clocks based on Arduino, this one has two distinctive features: a single…
Here’s a simple but essential tool for monitoring the 3Drag and print without the need of a connected computer: all this thanks to a cursor, an SD card slot and an LCD display. Obviously we applied this to our interpretation of the Rep Rap universe (the 3Drag) but you can really easily tweak and adapt…
Today we present you a stereo 10 + 10 Watts audio amplifier based on TDA7297SA, a monolithic dual bridge amplifier that is suitable to be used in projects that feature access to a single 12 volts power supply. This is a compact stereo amplifier: its field of application range from car stereo to portable audiovisual…
Being really open source is no joke. Open sourcing an hardware product, usually goes through several major steps. The first one is usually verifying that all the software is really open source, Free to use and adapt and accessible. It’s very important to stress this point, there’s a big difference in freeware (and in general…
Let’s expand RaspberryPi functionalities with a shield that is compatible with the Arduino pinout and with an onboard analog to digital converter with 16-bit resolution. Further expansions that we will present in the future will allow you to add a DAC, a number of additional digital I/Os and the ability to connect also with non…
It’s small but packed with features. The GSM alarm we present today, sports a PIR motion sensor, can be battery operated and it’s capable to communicate via GSM. It can transmit alarm conditions and receive commands from remote. It’s also capable to indicate problems such as is insufficient voltage supply or tampering. It’s not so…
After having shown several examples regarding the use the GSM/GPRS & GPS shield with calls and text messages we are now going to present some applications that involve GPRS data. Thanks to the inet.h class the shield can indeed connect to the internet and its various applications. We ‘ll see how to use the Arduino as…
This post is one in a series showing you the main features of the GSM /GPRS/GPS shield and of its related library. The examples are great to have inspiration and reuse the material to create your own solutions. We already talked about how to use the shield to make calls, send DTMF tones and…
A few months ago, we presented a powerful shield that can enable devices from the Arduino family (Uno and Mega) to interface with the SIMCOM modules SIM900 and SIM908. Such modules provide integration with the world of GSM, GPRS and GPS and all is achieved through very simple Arduino commands thanks to the open-source dedicated…
Whether it’s a personal, store or product page, popularity at today is measured in Likes: the number of users who liked your page, photo or any other content you posted on Facebook is a key metric of customer engagement and potential success for your venture. That’s why we decided to put together some clever…
[youtube id=”85cb6y2vNjE” width=”620″ height=”360″] The invention of the wheel, literally revolutionized the history of man. Thanks to it, it was possible to create forms of transportation, invent new industrial and architectural machinery. The wheel is so perfect that no one would think to improve it but recently some special, revolutionary wheels have been invented. These…
