Raspberry Pi 4

A few hours ago, the Raspberry Pi Foundation announced the latest version of their awesome single board computer, Raspberry Pi 4 Model B. I am stoked.

Raspberry Pi 4 with dual monitor support at 4K

As shown in the above image, it has dual monitor support at 4K. They switched the power supply to use USB-C and has Bluetooth 5.0 connectivity.

The new version comes with support for 1GB, 2GB, and 4GB of RAM. That makes it a powerful desktop computer that’s smaller than my phone.

I cannot wait to try this out and work on something fun.

Building a Coffee Pot Monitor using Raspberry Pi

I love coffee and side projects. I wanted to solve a coffee related annoyance that I faced on a regular basis. This post is about how I built a Coffee Pot Monitor, to track the coffee level in a coffee pot, remotely, using a Load Cell, HX711 amplifier, and a Raspberry Pi.

The Annoyance

Imagine yourself being busy with something important. You take a quick break to grab some coffee and walk over to the break room only to find an empty coffee pot.

Oh, the horror

There’s no way for me to know the amount of coffee left in the pot, without walking over to the break room and checking it out. The coffee pots we have at work are opaque. So, it’s not possible to know the amount of coffee left in the pot by looking at it.
