I love making beeps and bloops with the Arduino pitches library, but sometimes archaic 8-bit tunes just don't cut it. Whether you want your robot to terrify your enemies with a demonic synthetic voice, you just need a pocket boom box on the go, or you want to a miniature guitar amp, a simple LM386 amplifier can crank up those signals loud enough to play through any speaker.

Fireworks are the best part about the Fourth of July and other celebrations, but they can easily cause accidental injuries.

When BlackBerry first announced the KEY2 back in June, the biggest gripe we heard was about the price. It was reasonable criticism, as BlackBerry was asking a lot of its consumers at $650. Knowing this, BlackBerry went back, made some downgrades, and cut the price, creating the KEY2 LE.

Unlike traditional backlit LCD technology, OLED screens don't use any power to display black pixels. Many manufacturers have taken advantage of this by implementing an always-on display, which only lights up a few pixels here and there to show relevant info when your phone is locked. But this leads to extra battery drain, albeit small, and it increases the risk of screen burn-in.

OnePlus, whose phones always challenge for the title of best spec-to-price ratio, releases two main devices every year.
