It’s one of those horrifically dangerous 2.5×2.5×2.5 cm mini-cube singe port 1 A USB chargers. There were scorch marks on the base of the case. The circuit was very simple, a simplified SMPS on two small PCBs… which held into the cube casing with white silicone/glue – scratch that away and it is easy to extract the pair of PCBs
Whilst looking into the XTAR battery chargers, I came across the XTAR EU4, which offers QC3.0, 2 x USB 2.4A and USB C (PD) ports… although the QC and PD capability is a bit limited (i.e. QC has no 20V capability, and PD current is limited to 20V 2.25A (45W)), but not by much…
Looking for an internal 2.5″ 2TB HDD for your MacBook, or MacBook Pro? The cheapest option is to get a Seagate Backup Slim (STDR200020x where x=0/1/2/3) USB external disk and rip its guts out. It is the only 9.5 mm high, 2.5″ 2TB internal disk on the market (or was in 2015), and I believe that it still is – even in late 2017.
In Bangkok, an internal disk such as a Seagate Barracuda ST2000DM006 2TB 64MB Cache SATA III 6.0Gb/s is around 3350 baht, or more precisely:
Seagate Barracuda SATA III 128 MB 7 mm 2Y 3390 Baht
Seagate Firecuda SATA III 128 MB 7 mm 5Y 3850 Baht
whereas the Seagate Backup Slim is normally 2620/2590 baht (depending on where you shop), or 2360 baht on offer (I actually ended up paying 2290 baht at a sale, with a soft case and a OTG mobile adapter thrown in).
Other disks are too fat (i.e. tall) at 12 mm, or 15 mm, to fit in the MacBook internal disk bay. other heights may be 6 mm, 7 mm (ST2000LM00x, where x=3/7).
The STGD2000400 is physically the same disk (9.6 mm thick), but it is pre-formatted for the PS4. There is also an XBox formatted disk (SRD0NF1/STEA2000403), although, as the external case is 14.8 mm thick, the disk itself may be oversized – note that the external case of the Backup Slim is 12.1 mm.
Also covered are the Seagate Backup Plus Fast, and Seagate Backup Plus.
An issue cropped up on Stack Exchange Hardware Recommendations, relating to USB repeaters, for situations where the USB device was situated at some distance from the USB host, i.e. a PC. Described below is an attempt to address the problem of signal loss over the long cables required. Continue reading Active USB repeater
