Loveland High School Robotics


Today I visited the Loveland High School Robotics class. The have a First Robotics Team 1977 Power Squids.

I will be working with them as a volunteer mentor.

It was a very enjoyable visit. The had lots of interest in what I have done in the past. I brought Jay 10 my robot as well as my bionic hand. There were very knowledgeable.

I look forward to working with them in the future.


I am Back


Finally I have returned. Last July I retired from Intel in Hillsboro, OR after 2 1/2 years. I moved back to my home in Firestone, CO.

I will be updating the blog more often now that I got organized (Organized. Really? – Linda).

MAVBots  projects:

As I am a volunteer Mentor for the Mead High School MAVBots robotics club I built a couple of bots for them:

  • A Sparkfun RedBot. I upgraded the Line follower sensor and added better bumpers. I also added a pen and lift servo so it can function as a Turtle-bot.


  • MavBot. This is a 310mm x 280mm differential drive robot. It is basically a Redbot on steroids.
  1. it has stepper motors (NEMA 17 – Left over from my 3D printer Project  (see below). I used two  Sparkfun Easy Drivers for control.
  2. Arduino Mega2560 for the brain.
  3. SD card reader.
  4. Line Follower Bar.
  5. LCD Display.
  6. XBee Radio. and
  7. Polulu Micro Maestro to control servos.
  8. Pen Holder with Servo.

Stargate SG-1 Clock


Happy New Year to all!

I still have been very busy at work. 12+ hour days 6-7 days a week. I even had to cut short my Christmas Break and return before the new year. We are bringing up 3 new tablets!

Things quieted down a little this weekend so I had time for a quick Project.

A Stλrgλte SG-1 Clock!

(Yes I know the character is wrong, but it is as close as I can get)

Here is a video:


More details one of these days.


Getting ready for Portland Mini Maker Faire



Sorry for no updates.

I am working on a special project for Intel on the Edison which is taking all my time (even nights and weekends).

I may have an update before I go home for Christmas. I will be working on the motor controller and Quadrature encoder feedback to control motor speed and position.



Getting ready for Portland Mini Maker Faire



It has been a real zoo here getting my bot ready for the Portland Mini Make Faire at OMSI September 13-14. (Presented by Intel). I will be at the Intel booth presenting my Bot as a work in progress. Disclosure: I do work for Intel and they have been very supportive of this project.

My Bot now has a Name: 

JK-BOT (Mark V)

If is the Mark V as it is the 5th incarnation of my Bot.

I am posting a short video status report.  After this weekend I will go into all the details. Here is a link;


Back Again

August 20, 2014 (Updated 8/24/14)


I have been working hard and traveling to Austin, TX and Seoul, South Korea. That took lots of time along with the special projects here at work.

Well I’m back and working on yet another version of my robot.

I was not happy with the base of my previous version.  Due to the steel  I used in construction it was too heavy (26+ lbs), hard to work with, cut and drill, and it was magnetic. Being magnetic means that it work cause my magnetometer (used for  direction sensing) to not work.

The new base will be aluminum. It will have an outer frame of 1″ square tubing. The deck will be 1/16 aluminum sheet I got from Surplus Gizmos. It is a lot lighter and easier to work with.

I am still trying to figure out how to mount the electronics and build the superstructure (I.E. Body). I hope to have the motor mounted and the base electronics in by the end of the weekend. I will post pictures then.

Apdate:Here are the pictures of the new base with the motors mounted. Also I have added ServoCity to the list of link. I was showing the parts I use from them to a co-worker on Saturday and realized ServoCity was not included. OOPS. Since I use their Actobotics Logo - page parts and they really deserve a mention.


The frame is 1″ x 1″ Aluminum tubing. The deck is 5/64″ sheet. Size is 24″ x 24″

Hi again.

Last night I took some more pictures of the assembled base. I also weighed the base. It came out to 26+ pounds! That’s what 1/8″ steel will do for you! Now on to the pictures –

Views from the front, back and one side.

Side close up.



The back now has a power switch. Also the power bus connectors I got from Adafruit. They make one convenient place to hook the master 12V and Ground.

In the front there is a 5″ wide electronics shelf. It contains the Motor Processor (UNO), DRI0018 Motor Driver board, and a 5V power supply. The motor controller will communicate by I2C to whatever Brain is mounted to the upper. The upper portion is designed(?) to be interchangeable. I can put a Telepresence top on, a Manipulator arm, or a Machine gun :-). It is limited only by imagination. Currently I have a Bluetooth module on the motor controller to send commands to for testing.

Well that is all for this year. I will be traveling and visiting the Colorado homestead for all od December.


Happy Holidays

and see you next year!
