iCloud sync exclusions#

One can avoid syncing a file or folder in iCloud drive by adding a .nosync extension to it (for a file) or a .tmp extention to it (for a folder). Quite a bit backwards if you ask me, but it is what it is.

A few TILs and notes for Fnirsi FNB-C2#

Got this USB power meter/tester a few weeks ago

Updating Fnirsi FNB-C2 Firmware#

  • Download the firmware from fnirsi website
  • Press “OK” on FNB-C2 and connect a USB cable to the data port (USB sign) on C2 and to a PC
  • A drive will appear on the PC with about 8 MB size
  • Unzip the firmware and copy the bin file to the drive
  • It’ll take a couple of minutes or a bit more, without appearing to move but when the copying is finished, the device will automatically reboot with the new firmware
  • You can check the firmware version by going to Settings->About on the device

Running a capacity test on a device using Fnirsi FNB-C2#

  • This can be done directly on the FNB-C2 device itself but it has a limit of 9 hours max, which may be problematic if you are testing a large capacity battery/power bank etc. Hence, the need to do it on PC which doesn’t have such limits.
  • Download the USB Tester Tool software from fnirsi’s website.
  • This works only on windows or linux
  • Open the software, and connect the FNB-c2 device to a USB port on host to the data port on c2
  • Set the sampling rate (anything you want according to need), start cur (acc to need but non zero preferably), stop cur near 0 (but not exactly 0, something small. Otherwise there’s some minimal current always flowing even after the battery runs out), stop time to 5 seconds or so. Then click on create and then start
  • Connect the input and output ports on the c2 to the device under test, and the load respectively
  • Make sure the CAP and NRG items under Auxiliary Record are set to record/display as needed
  • Now, sit back and let the capture happen
