First post in a long time

February 11th, 2019

Time flies when you are having fun (and when you are not having fun).

Five new PCB’s designed, a consulting project that lasted almost two years, and moving my home (and lab) conspired to keep me from writing here. The site getting hacked due to WordPress issues a few times did not help.

I am re-organizing my new lab (and wifey is making me take time off) however I do have a minor update today as RoboPiLib3.py is now available on the RoboPi product page at:https://www.mikronauts.com/raspberry-pi/robopi/

Coming soon, three new products (I just have to document them) with two more to follow after I finish the firmware.


Mikronauts.com is BACK!

Sorry for the outage.

We were hacked, and I thought I fixed it (twice) however I did not realise that MANY php files were infected.

A malware scan by my hosting company found 62 infected files, so they suspended my account.

Unfortunately I was away from my office (another project, then my wife insisted I needed a vacation.. she was right) and I was not able to scrub the files until I got back to the office.

After the scrub, my hosting company was kind enough to load the latest WordPress and fix an internal issue, as I was getting the dreaded 500 Internal Server Error problem.


Sorry.

Spammers managed to post some more spam… deleted.

They should get a life.


Site hacked, new articles resuming soon.

Bad news:

Sorry folks, my site was hacked by spammers.

I restored it from backups, updated wordpress, and changed my password … only two posts were lost.

Good news:

I will be resuming posting new articles soon, the projects that kept me too busy to post are basically done!


Serving Raspberry Pi #7: Meet Berry Bot

October 26th, 2016

The November 2016 issue of Servo Magazine is out – and I got the cover!!!

servo201611cover_web

It this article I started building Berry – a RoboPi + Raspberry Pi 3 based 4WD robot.

As you can see, Berry has a red 4WD chassis, Patriot USB power bank, RoboPi, Raspberry Pi 3, Sharp IR distance sensor, and a 9g micro servo.

What you can’t see is that Berry also has an L298N motor driver board, HMC5883L used as a compass, and a 4xAA cell battery pack to power the motors.

This article shows how to connect the parts, and presents some simple Python code for the compass.

For the full skinny, read Servo 🙂 https://www.servomagazine.com/

Unpaid plug: if you are into bots, I highly recommend getting a Servo digital edition subscription – which also lets you read all back issues (including my past articles <grin>)

BTW, sorry about the lack of posts & articles, other work kept me busy.
