WattUp combats this problem with a type of beam-forming technology. That Bluetooth connection is used to focus a tight cone of electromagnetic waves on the target, and it can even track the device and recalibrate as needed. A standard Qi wireless charger is about 90% efficient, but Energous claims it can hit 70% at much greater distances.
Flash memory cards for digital cameras are now absurdly cheap. A 64GB SD card can be bought online for around Â£30. Thatâs enough space to store 5,000 raw files produced by a typical DSLR â or upwards of 30,000 JPEGs. These cut-price cards come with a caveat, though.lash memory cards for digital cameras are now absurdly cheap. A 64GB SD card can be bought online for around Â£30.

With Wii Menu 4.0 and above you can use up to 32gb SDHC cards. Full details can be found on Nintendo's customer support site. You can use SD, SDHC and miniSD or microSD with adapters. I think the important thing to note here is that the wii seems to prefer Fat and Fat32. Fat32 maxes out at 32gb, so anything larger than that is going to probably get stuck in NTFS or exFat and the Wii isn't going to know what to do with that.
