I’m not so handsome and talented as Harvey Keitel, I actually solve people problems.

Quite often people ask me what I do for living, and I always struggle. Am I a programmer ? Web developer ? Software Engineer ? Software Architect ? Technical Lead ? Technical Director ? – I owned each of these title among my carrier and still don’t know what is the best one.

I think my best skill is intuition – sometimes I just know what it’s going to be a bottleneck in software / setup or just know what is the best solution without testing it first. I usually do test it later, to make sure that I’m right.

Anyways – please check my work to see what actual problems I did solved…

NodeMcu (ESP8266) water level monitor with a voltage sensor

This subject in the theory looks very easy. Just get NodeMcu board, plug sensor from the family of sensors (HY-SRF05, HC-SR04), some kind of voltage sensor and we are good to go. But you can get couple of unexpected issues here. Let’s start from the NodeMcu unit. It’s specific.

Arduino double relay keypad lock

I needed key-less way to open my garage door. Quite often I forgot my remote, so just need something easy to open them without remote. Because I have regular “ring type” opener (click and release to open door) needed something to “click” door for me based on something which I remember (not own – remote / key / etc). Basic idea – keypad + arduino + relay to click the button.

USB to TTL / Serial MacOS Mojave

Got a bunch of these little f*ckers and couldn’t make them to work with my Mojave fresh install. Previously they were working, and now they are gone. I wasn’t sure what exactly I’ve got. I just run Serial Detect to identify what model do I own:Then I googled driver for MacOS Mojave. Because original website: CP210x USB to UART Bridge VCP Drivers likes to file, I made a mirror on my server.

Quote - Get out of life what you deserve

“Spend each day trying to be a little wiser than you were when you woke up. Day by day, and at the end of the day-if you live long enough-like most people, you will get out of life what you deserve.” — Charlie Munger

quote of the month

“Most people never pick up the phone and call. Most people never ask. And that’s what separates, sometimes, the people that do things from the people that just dream about them. You gotta act and you gotta be willing to fail.” — Steve Jobs

There are only two hard things in Computer Science: cache invalidation and naming things.” — Phil Karlton
