Engineering your mind in electronic inventions is not everyone’s cup of tea but a born enthusiast cannot ignore its guts for a long period. Dansku or Daniel Andrade in his recent post has detailed about its unsurpassed urge to create DIY projects while pursuing electric engineering.In this simple project, Daniel has shared a blog that defines how to shape a metronome via some simple parts, which are readily available in any electronic shop. To begin with, a Metronome is any device that generates a structured audible and visual pulse, habitually utilized to create a stable beat, or tempo and computed in beats-per-minute (BPM) for the execution of musical compositions.

In yet another post, dansku has attempted to relive the past of technology. From connecting computer to the old 32′ TV in order to watch things from the internet to the era of eMule, which was ruling the p2p community or to the introduction of HTPC (Home Theater PC), a dedicated computer that gets connected to the TV, with good Motherboard/VGA/Soundboard and with gaming aptitudes.The inventions never stopped and so the demand for technology. In this tutorial, Daniel has used a 2TB Lacie Network Space 2, which is a simple NAS Server, and a WD plus Live. The WD PLUS LIVE is a small computer with an operating system to playback videos and music with no storage facility.

Time and again, it is entertaining to make use of daily items to create something innovative and ironically, this project itself is using a pizza box to bake itself. In one of the DIY projects of statusorel, they have developed a solar oven by using a pizza box.All they have used is to make this device are Cardboard pizza box, Box knife or scissors, Aluminum foil, Clear tape Plastic wrap or a heavy-duty or freezer zip lock bag will also work, Black construction paper, NewspapersRuler or wooden spoon and a Thermometer.

A Casio PT-82 was considered as a classic of Casio 8 bit technology before the famous SK-1 came in market. A LushOne kit can be used to modify simple keyboards.  But PT-82 does not has a circuit bend as the SK-1.The useful modifications that can be made are quite limited. The sliding switches can be stripped back to individual components, plastics can be removed from the debris and the springs can be adjusted on the sliding switches.In one of the tutorials of Lushproject, base can be used to add a filter with LFO input to the cut-off frequency and a ring modulator with second oscillator input to the PT-82.

We are completely familiar with the fact that Lithium Polymer Batteries contains great power in a small package. But they are designed in a manner which is considered tricky in order to charge securely. In a tutorial of Adafruit LiPo Chargers project, a charging cycle is designed for safely charging 3.7v Lithium Polymer cells.This project aims to design the batteries that can adjust more than 3.7v. But forcing more voltage into a multi-cell pack is dangerous. Therefore, Adafruit has come up with another tutorial that shows how to safely charge multiple cells while maintaining a balanced charge.
