I created this page so that I may share my electronics, Raspberry Pi, Linux, Python and Java projects with others. 
A panorama picture of my work area :-)
Have tried to write some documentation to explain usage of the projects.
If you have any questions, just send me an email steelsquid@gmail.com
My main project now is:
Below is some news about my projects...

2016-05-22 Squidscout
This is my new project Squidscout.
It is a 6wd rover with rocker suspension.
I did not like the skid steering from my last rover so this one can turn the front and rear wheels.

2016-04-25 FPV Squid Rover
My rover with 8 wheels :-)
It is controlled by my FPV Control Station.

2016-04-12 FPV Control Station
Built a new control station for my rover. 
It work with my old rover: FPV Rover but i work on a new rover with 8 wheels and suspension. 

2016-02-27 FPV Rover
I have rebuild my Large Rover to the FPV Rover.
It has a 2.4GHz video transmitter and the video can tilt up/down and right/left.
I also made a remote control to host the screen for the video and the control buttons..

2016-02-08 NRF24 Rover
I wanted a rover with longer range (WIFI is to short).
In this robot the video and control signals is transferred by NRF24L01+.
The video is very low resolution and frame-rate (320x240, about 1 frame a second).
And a also build a remote control with a Raspberry Pi 7" Touchscreen Display

2016-01-27 Mini rover

This is my smallest robot 20x20cm and 9cm hight. 
You can control it via WIFI like the other robots but this also has 8 HC-SR04 distance sensors. 

2016-01-23 Large rover
It is about 50x50cm with 20cm wheels and uses PiBorg Diable DC motor controller.
It has the same control system as the Small Rover but it do not use the internal DC motor controller.

2016-01-14 Small Rover
Control it on a HTML5 webpage via WIFI.
Drag on the right side of the screen with your mouse or your finger to control the movement.
And drag up and down on the left side to tilt the camera.
Double tap on the screen to toggle the light.

2016-01-04 Steelsquid PIIO Board
My expansion board for the Raspberry Pi is finally finish.
The board is 120x100mm and is connected to the Raspberry Pi with a female PIN header and two 18mm spacers.
It has
DAC, ADC, PWM, Buttons, LED, LCD
Accelerometer & GyroServo, DC motor controller and more...

2016-01-03 Steelsquid Kiss OS
New version of Steelsquid Kiss OS (v1.1).
Switch ti Linux kernel 4.1
Super fast boot about 10 seconds.

2015-12-19 New version: Advance example how to use Steelsquid Kiss OS
This is a example project how to use Steelsquid Kiss OS to control a 10 LED bar, two buttons and the built in WEB-server.

  • Press the upper button to light one more LED until all lights.
  • Press the lower button to decrease the number of glowing LEDs.
  • The bottom LED should never be extinguished when you push down button.
  • I also want a simple WEB interface that also can control the LED bar in the same way.
  • And finally all LEDs should illuminate on network connected.
  • And no LED lit on network disconnect.
  • Flash all LEDs when there is a file in the /root directory named flash.
    And then delete that file.
  • Remember number of lit LEDs from last time
  • And a parameter that say if Steelsquid Kiss OS is to enable all this

2015-12-17 Steelsquid Kiss OS
Finally a 1.0 version of Steelsquid Kiss OS.
Super easy to extend functionality...
And also a windows EXE for the synchronization script.

2015-10-25 Alarm/Surveillance
The Steelsquid Kiss OS Alarm/Surveillance functionality. 
Connect different sensors to monitor your house or other thinks.
Now also a
Android app that automatically send arm/disarm to server...

2015-03-13 Clay Target Thrower Remote
Clay target thrower remote that i built for a colleague.

2014-12-25 Extend functionality of Steelsquid Kiss OS
How to develop and extend functionality of the Steelsquid Kiss OS.

  • Get the source code
  • Install Steelsquid KISS OS on the Raspberry PI
  • Automatic upload changes to Steelsquid Kiss OS

2014-10-09 4WD Rover
Building a 4WD robot controlled from an Android app. 
Here is a short video, going to write a bit more about it later ...

2014-07-01 Experiment case
Wanted a portable electronics experiment case, So I built one :-)

2014-06-15 Experiment board
This is an experimental board that I built as a birthday gift for my brother.

2013-12-18 Device Monitor
Monitoring and control an old pellet feeder.

2013-01-10 Steelsquidify
