Hello world!

Welcome to Arc’s Lab!

As you can probably notice the site is pretty much useless at the moment since I just started it.


Here I will present my own electronics projects/circuits and provide all the schematics and instructions required to build them. You can also expect to find some random posts mostly related to electronics as well as component tests and small circuits which have extensive applications in other projects.


As soon as possible! I already have some cool projects for you, just be patient until I write something meaningful.

For whom?

Mostly for semi-experienced people interested in electronic and DIY. I will assume you know some basic theory and have skills necessary to etch your own PCBs and solder components in place.


In plain english and without much fuss! Expect some gramatical and spelling errors since english is not my native language.

“See” you soon!

    Hello Arcom, I’m italian,
    I’ve build your pic countdown timer and it work very well.
    But I wold use this timer for other scope, in a timeout in a game.
    I need to modify the start time up to 60 minutes and, if possble, to take out the pre heat, the rest is fine.
    I ask if you can send me the source code, I’ll modify it myself.
    I’m not a programmer but something I undestand about it.
    Can you send me it?
    Thank in advance.

    Hello everyone, it’s Penny here!
    I work as a professional an essay writer and have created this content with the intent of changing your life for the better. I started honing my writing talent in high school. I learned that my fellow students needed writing help—and they were willing to pay for it. The money was enough to help pay my tuition for my first semester of college.
    Ever since high school, I have continued to work as an academic writer. I was hired by a writing service based in the United Kingdom. Since then, the research papers that I have created have been sold around Europe and the United States.
    In my line of work, I have become familiar with hearing, “Penny Allison, can you help me meet my writing assignment deadline?” I know that I can provide this service.
