Choosing the wrong battery can backfire: alkaline vs lithium-ion differences

Differences between alkaline and lithium-ion batteries depend more on device use than on performance alone. Alkaline batteries are widely sold in common sizes, are relatively cheap and easy to find, and suit low-drain devices such as remotes and wall clocks. Lithium-ion batteries are rechargeable and store more energy for the same size, making them common in smartphones and laptops. Users should also distinguish disposable lithium AA and AAA from lithium-ion packs and follow compatibility and disposal rules.

Valve VR headset Steam Frame earns points for repairability, cooling fan is the problem

Valve\'s VR headset Steam Frame is generally designed to be easy to repair, but replacing its cooling fan requires a complicated teardown, a report said. iFixit cited the fan’s deep placement inside the device as the biggest drawback, requiring removal of optical modules, cooling parts and cables. Other parts were easier to service, though the battery lacks pull tabs and controller joysticks are soldered. Parts availability is also an issue.

Wireless controller history goes back more than 40 years, starting with Atari

The history of wireless controllers, now standard gaming hardware, dates back more than 40 years. Early examples include Cynex\'s Game Mate2 from around 1982, which worked with the Atari 2600 using radio frequency signals. A major turning point came in 2002 with Nintendo\'s WaveBird for the GameCube, improving range and battery life. Sony adopted wireless controllers with the PS3 Sixaxis in 2006, later restoring vibration with the DualShock 3 in 2008.
