⚡People ask why I’m proceeding so slowly on my various electronics projects.⚡

For one, I am learning.🏫 It takes time to figure out how to design something, to experiment and learn what works and what does not. No reason to order components or tools that I might never ended.

Second, it saves money by buying less.🤑 Sure a $5 or $10 box of random components may not break the bank, but my budget is pretty tight, and things add up in cost. It’s better to enjoy what I have already before moving on to a next step.

Third, I like dreaming of what I can build.🤖 Sometimes it’s more fun to dream about what can be built and draw things on paper, then see the final product. Some projects exceed expectations while other don’t. Once a project is done, there is nothing to envision going forward

Fourth, electronics are one of many interests.⛺ There are many things to take up my time, from hiking to camping to fishing and hunting. I also have the blog to work on updating, maps to make up, things to read about, events to go to.

As an electronics hobbyist, Amazon and eBay are a great source of low-cost electronics components.⚡ While they aren’t instantly delivered to your mailbox or door, especially not having AmazonPrime, there is a lot of selection and they are low-cost.📬

But what does bother me about these services is how much non-recyclable packaging ♻they contain. Electronic components are particularly bad, they often come packed a tyveck envelope, wrapped in bubble wrap, then in an anti-static bag – all of which is pretty much garbage.🗑I get the need to protect sensitive components in the mail, but sometimes the amount of packaging you get is unbelievable.📦

About three weeks ago, I ordered some LED aluminum channel from Amazon. It was a good price, but it came in an enormous box, which inside was another box, and then the product packed in shrink wrap and foam paper.🎁 I understand the need for the foam paper, and maybe inner box, but the big outer box seemed like such a waste. At least that can be recycled.🚮

Both major online retailers rarely package things in Styrofoam peanuts these days, preferring to use air-filled plastic bags instead. They are easy to pop and reduce down to little waste. But there are still too much that comes in tyveck envelopes, too much that comes in bubble wrap.😡 I don’t have trash pickup, so I have haul all that crap to transfer station and pay to get rid of it, and know it will sit in a landfill forever. It’s annoying.💩

Raspberry Pi or Arduino Uno? One Simple Rule to Choose the Right Board

While I've been doing a lot of playing around with my Arduino Uno, I was also curious about the Raspberry Pi, which is more like a mini-computer that runs a stripped down version of Linux then a microprocessor that executes relatively simple instructions in a big loop. This article gives a good description of the differences, but another one to consider is power consumption, especially if your unit is going to be powered by a battery or other limited source. The Arduino Uno R3 less then 750 mW of power, compared to the Raspberry Pi which uses 3,500 milliwatts. Granted, 3.5 watts of power isn't a lot compared to what you would be running off it like lights, but adds up when your counting every watt.

What is an Arduino?

"Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board."

"The Arduino platform has become quite popular with people just starting out with electronics, and for good reason. Unlike most previous programmable circuit boards, the Arduino does not need a separate piece of hardware (called a programmer) in order to load new code onto the board – you can simply use a USB cable. Additionally, the Arduino IDE uses a simplified version of C++, making it easier to learn to program. Finally, Arduino provides a standard form factor that breaks out the functions of the micro-controller into a more accessible package."
