This will be my last post on how to get wifi working on a raspberry pi because I’m going to buy the pi 3 from now on with inbuilt wifi. With a cheap as wifi dongle and changes in the OS from Wheezy to Jessie, getting wifi to work is a nightmare. I keep getting… Read More »
This post here got me started on the right track. Here, I specifically focus on the Arduino Due. Step 1: First connect your computer to the Arduino Due to the programming USB slot. The one closest to the power supply barrel. Connect the native USB to the raspberry pi. Step 2: Double check that the… Read More »
Here is the easiest and quickest way to get up and running with an Arduino Due on a Mac. Step 1: Plug the micro usb to the usb port closest to the DC power supply. This is called the programming port. (ref: https://www.arduino.cc/en/Main/arduinoBoardDue) Plug the other end into your Mac. Step 2: Download the Arduino software… Read More »
There are basically 2 ways to set up VPN on a Raspberry Pi. There is an easy way and a hard way. Use the PiVPN installer (https://www.sitepoint.com/setting-up-a-home-vpn-using-your-raspberry-pi/) Download and install OpenVPN manually (http://readwrite.com/2014/04/10/raspberry-pi-vpn-tutorial-server-secure-web-browsing/) The PiVPN installer is very neat and very cool and saves a lot of time. The disadvantage is that you are running… Read More »
I had always used Win32 Disk Imager to create my Raspberry Pi images because I was a windows person prior to my conversion to Mac. To be honest, Win32 Disk Imager was really simple v trying to understand command line such as: sudo dd bs=1m if=path_of_your_image.img of=/dev/rdiskn I finally took the leap and gave it… Read More »
The secure copy command is: scp where_the_file_is where_the_file_should_be Or more correctly: scp source destination The trick with a raspberry pi, or any remote location in fact is to include the username@host/ip with a colon as the first part of the source address. eg scp pi@192.168.x.x:/home/pi/text.txt ~/
After managing to get my wifi dongle working on my raspberry pi 2, I connected it to my Samsung S6. I could see it connected or “tethered” to the mobile hotspot I created and tried to SSH into it via it’s IP address. Needless to say it didn’t work due as my laptop and the… Read More »
Getting a wifi dongle working on a Raspberry Pi can either take 5 minutes or 5 hours depending on a lot of factors. If you have the right dongle and a fresh image, it is essentially plug and play. All the drivers will be there, the dongle will be from a recognised brand and all… Read More »
If you want to connect your raspberry pi to your Mac with a USB to TTY cable, the easiest and quickest way is to visit the Profilic website and grab the right driver. This is assuming your USB to TTL Serial Cable is running a PL2303 chip like this one here: http://www.adafruit.com/product/954. On this page,… Read More »
