Raspberry Pi 4

Raspberry Pi 4 Model B

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

Coffee grounds and Coffee

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.

Google Fi Review (2019)

Google Fi

After ten years of using AT&T, I switched to Google Fi and here are my thoughts. Before I start my review, here’re some details you might be interested in. I use Google Fi on an unlocked iPhone XS. I knew very well about the limitations before I signed up for the service. So, here is my review of Google Fi on iPhone.

Application

I’ve been a Google Voice (GV) user since the past ten years. I love the service. I’ve used it for my voicemail and for making international calls to India. I liked the voicemail transcription feature too. This is a pretty common feature now, but, GV pioneered it.

Anyway, I was able to sign up for Google Fi online from this page here https://fi.google.com/signup and apply for the SIM card installation kit.

Working on Side Projects

Working on Side Projects can be really fun. But, you know what’s not fun and sucks? Not finishing the project and abandoning it (also, Global Warming). This is a very common problem and most of us struggle with it.

It gets trickier. Once you lose interest in the project and abandon it, guilt kicks in, as if we don’t have enough issues to deal with already. At this point it becomes really annoying having to fight with your conscience about the abandoned project. You don’t feel like working on it and at the same time you can’t really leave it. It’s just pure bliss at this point. 😇
