A small wind generator which can be installed on a balcony or on the roof, capable of providing electricity to store in accumulators in order to power, for instance, domestic utilizers such as the video surveillance system when we are away from home and we cut off the main power. Second only to…
PGCPSU is a three in one power supply board and it integrates a lithium battery charge management circuit with 5V and 3.3V DC-DC converter-based output rails to power most projects in a very compact form factor. This affordable yet powerful LiPo PSU module is available on Kickstarter from just €7 and worldwide deliveries expected to…
A small Arduino board with minimal hardware but with access to all I/Os, just like the Nano and equipped with PCB-integrated, direct-insertion USB connector: it is basically an Arduino Pen Drive. Since Arduino had been launched, many derivative products had been “sprouting” on the market, created by numerous companies thanks to the public availability…
A new Arduino-like board ready to “devour” the competitors: not surprisingly, it was called Shark. Let’s see how to use it. Second and last episode. Read the first post about Fishino Shark The sea of Fishino, our series of prototyping boards compatible with the Arduino family, has recently completed its population: as we have…
A new Arduino-like board appears on the horizon ready to “devour” the competitors: not surprisingly, it was called Shark! Let’s see its features. First episode. A shark appears in the Fishino sea, whose sharp teeth are its leading characteristic: they allow it to “bite” the applications. Shark, as we called this new board,…
Hardkernel failed to deliver the $100 Rockchip RK3399-based Odroid-N1 developer board last year due to component shortages. But it’s now back with a successor, the Odroid-N2, which is cheaper and performs significantly better in benchmarking tests. The ace up the $63 board’s sleeve is its performance, courtesy of four 1.8GHz Arm Cortex A73-based processors and…
YouTuber Electronoobs has just created an Arduino Nano multimeter device. Using a small OLED screen in combination with the Arduino Nano together with a couple of buttons and 16-bit ADC for precise measurements the multimeter is able to display voltage, resistance, current, and it’s also capable of reading capacitance and inductance. Power is provided by…
12 Vdc to 220 Vac inverter with modified sinusoidal output waveform and maximum power of 600 watts. The inverter is equipped with overload protection, input overvoltage, short circuit and low battery alarm. It has USB output (5 V – 500 mA), Schuko socket and can be used to power: TV, VCR, PC, HI-FI systems, refrigerators,…
Youtuber Electronic Grenade, a DIY enthusiast, has created something truly impressive in the form of a mouse that doubles up as a full-fledged computer. Aptly called ‘The Computer Mouse’, the device has a small colour display, a slide-out keyboard, and of course, a fully-functional mouse which also forms the main body. The mouse is a…
Automatic switching battery charger for 12 volt acid lead type EFB, AGM, GEL, etc. Controlled by a microcontroller, it performs the diagnosis and the battery charge in total autonomy. Comes complete with cables with insulated pliers. Input voltage: 110 – 240 VAC – 50/60 Hz – 250 mA Output voltage: 12 VDC Charging current: max….
Given two batteries, it chooses the one to connect to the load based on the voltage measured at their poles. It can also be used to switch DC power supplies. The growing demand for portable devices capable of working where there is no power grid or it is not convenient to use it is…
An audio file player based on an MP3 module with FM radio, Bluetooth and remote control; a 10 V stereo output and two speakers are used for the listening. The device can even work via outlet or using two 3.7 V rechargeable lithium batteries. We all know we can find any kind of loudspeakers…
