Turn off USB and LAN on the Raspberry Pi 3B+

By
Turning off the USB and LAN can save around 200 mA of power. However, it is not possible to turn off individual USB or LAN separately as they are sharing the same I.C. Below are the Linux commands to turn off and on the USB and LAN.


Turn OFF USB chip

echo '1-1' |sudo tee /sys/bus/usb/drivers/usb/unbind

Turn ON USB chip

echo '1-1' |sudo tee /sys/bus/usb/drivers/usb/bind

Note: The Linux commands are temporary. Once the Raspberry Pi rebooted, the USB and LAN will turn on back.

A Better SKMEI 1418 / 1427 Instructions Manual

This SKMEI 1418 / 1427 digital watch is a great outdoor watch for a really cheap price. However, the instructions manual is far from good. It took me some time to explore some of the functions and at the same time trying to understand the instructions manual provided by SKMEI. I decided to write an alternative instructions manual for this watch so that other owners of this watch might benefit from it. But never the less, I am not a good English language writer myself. But I do think it is still better than the instructions manual provided. Feel free to correct me using the comment section.

SKMEI 1358 Review

I bought this watch four months ago and I have been wearing it every week during my weekend hiking. Overall this watch is impressive considering the number of features per the price that I have paid for it. All the features worked flawlessly considering that this is a relatively cheap watch comparing it to Casio ProTrek range of watch. SKMEI 1358 is basically an equivalent of Casio's triple sensors watches. You might know them as Pro Trek or Pathfinder in North America. It has a barometer, a thermometer, and a digital compass. It also has an extra sensor that the Pro Trek watches might not have as far as I know of. It has a pedometer. Yes, it counts steps and estimates the calories burnt and distance traveled. With the combination of these sensors, this is an ideal outdoor watch you can have for a fraction of a Casio Pro Trek price. SKMEI 1358

In order to share your Tasker love (projects, profiles, tasks or scenes) to all Tasker users, you will need to export Tasker's projects, profiles, tasks or scenes to xml files. Anyone out there looking for a specific automation for their Android phone could just download and import the xml files into their Tasker Android application and tweak the automation to suite their own use. Somehow i felt that the export and import functions are not that intuitive. I did took a bit of time and Googling to find out how to export and import properly. This post will show you how to access the export function in Tasker.
