"Brian" Lives - Spawn of the North

Introducing my latest Robot "Brian" :-

Born             :-   Friday 23rd September 2011 @ 10:30 BST

Weight         :-   60 grammes

Dimensions  :-   2.5″ x 2.0″

Gender         :-  Hermaphrodite

    It is my first attempt at creating a cost effective "Swarm" bot ....

.... Brian is learning fast, though is only crawling at the "MoMo"

Mystery Autumn 2011 project

Mystery Autumn "Guess wot the Heck Gareth is doing now" project

RFID Keylock - RBBB Propeller

Continued......... Video explains the details ....including the painstaking job of finding the right house wires....ekkk

Removed the "Elfish PC" as its needed on another project.........

..... Replaced with a super cool RBBB Propeller board M44D40 found on the parallax forum, for 20 dollars.

I choose this board because of its size and simplicity (it has to fit inside my RFID box) .

RFID Part 2 - Multipass Cuckoo

Continuation of Hacked Multipass RFID reader ......

Now updated with absolute decode of the 19 byte "Secret-Cypher" hex string to 10 digit readable numerical string....YAY

RFID "Multipass"

RFID reader hacking success.... 19 bytes of raw data .......

Question is  shall i go Arduino or Propeller ? .....or even Picaxe (just in its grasp)

RFID hits the ShoutBox

Just wanted to share this........

 I bought a new RFID reader .......

It installed quite nicely all by its self  as a HID (Human Interface Device)

Now i was clueless "Wot2Do" with a RFID HID.... soo.....

.... yes ask the ShoutBox someone will point me in the right direction......

$2 Elfish computer "BlueTooth" Upgrade

For the cost of 4 resistors and a $1.80 Bluetooth dongle - your Propeller chip can join the wireless environment.

....again the Propeller chip just bowls me over with its amazing capabilities.....

For more details of how to accomplish this....... zip over to Elizabeth Scotts site

EDIT :- Now confirmed working with 2$ dealextream Bluetooth Dongle.

Gareths Elvish Propeller Mini Computer Framework.....

I needed disparately a mini platform for development - the propeller can be easily set up to read ps2 keyboard/mouse and output a composite video signal, plus sound and if i play my cards right a usb bridge interface for my phone.

All i have basically done is sit the propeller usb board into an ic socket and soldered 2 IDE diskdrive sockets either side - allowing me to use the system like a breadboard for experimentation. On the back i have wired in sockets for mouse and keyboard.

My Wii-camera will just plug into the ide socket....... oh this is going to be soooo magic..

Walk this way (JMEWalker Clone)

I could not resist making a clone of a JMEMantzel walker (NOT the spidertank mech) as featured in his video Here.

This is just a mock-up to understand and tune the walking mech.........before.....

shrinking it to half (or quarter) its size - controlled by central servo for turning..............

The Barcode input method i will be expanding as well.

Do you think a picaxe 08M is up to the job ?      (servo-motor-barcode)

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

This is my latest FireFly codename Megan40 ...... because she sports 40MΩ feedback resistors

If you need detectors that are not affected by ambient light then i highly recommend using UltraViolet LEDs as detectors.

The detect circuitry is finished - next part is to shoehorn the picaxe 08 onto the back to control servo and UV glowtube.

"Jar of FireFlies" - 08 picaxe LM324 opamp Syncronisation

Here is FireFly C10 detecting the UV glowing light off FireFly C224

C10 then synchronises and flashes in unison with C224

"Jar of Fireflies" part 2 - Enter the "No.10"

Second FireFly is in the Jar........ code named "No.10"

Disassembled Green version.

1 UV LED and 2 caps = 6 legs ....... one set of 3 is the positive and other set of 3 is the negative )-:so it can not cross its legs :-(

Glow PolyMorph Ultra-Violet LED body has a bit more "Organic-ness" to it now........

"Jar of Firefly" part 1 - Early Summer Project

"Jar of FireFly"

Ok its a start before the summer comes - by then the jar.....or a bigger jar will be full of Anamatronic FireFlies.

The idea is that the jar just keeps them safe - then i can open it up take them out and deploy the fireflies onto a bush or tree etc-etc

They will be controlled by picaxe 08s (128byte brain) in theory 1 picaxe will control 3 Fireflies.

"Cry Baby Cry" & Video

BlueSun organisation is loaming - "a something else" product - be sure to tune into the "wave".

Care to guess its purpose in life ............. ?

Urgent Search :- Need to find Serenity or Firefly  theme tune ..for picaxe - can any browncoats help out !!!!!


G³ = Gareth Going Green

Gareth is Going Green (G³)........no suprises.........

At long last..... 

Just had last bits in to go a little "Solar Friendly" ...

.....First Etape "in the bag" :- my Main Compy is running "Green" off Solar power.....

.....(not sure for how long on one charge though, so far so good....)

.....2nd Etape - Solar lighting (not sure what or how yet)

Mr.Lassiter - Mr.Prop - Mr.Lazer - Mr.LiiDar - Mr.Risc- who knows

Having built the Lassiter i wanted to make it mobile so that it could go for a spin..........(with a spin)

Being resourceful i raided the chassis off my Mr.Tidy (sorry OddBot but it has to be Hacked sooner or later)

The "Lassiter" laser LIDAR Ranging Gadget (Wiimote/Propeller)

Introducing the "Lassiter" , an inexpensive laser LIDAR Ranging Gadget (Wiimote/Propeller based)

I have been troubled for a while Re:- Laser experiment It required a Bluetoth connection to a pc for it to work.....

..... now i have removed this "MiddleMan", all can be done with a simple parallax propeller system ....YaY

What you see here is my first successful setup :-

AOP - Just look at those legs

One "SchneeBeast" on its way to Gakken Japan .... .... Next day a suprise Package from Gakken Japan

Contents :-  Glossy Magazine with my SchneeBeast in print, (riks TJWalker is on top of page too)


Construction Details of SchneeBeast soon be found here on LMR :-

SchneeBeast (link is live for the moment - it will all become clear shortly)

...... here she is strolling in the snowy Appenzeller Alps .... but not for long .... do i hear Mt.Fuji calling.

Edit :-  "Waves" are starting  Gakken

parallax Propellor Based Web Server , controling digitals and servo controlled camera

My Propellor Based Web Server is taking shape.

At the moment i am able to control

  • Digitals
  • Servos ..... just general positioning sweep commands at momo

However still i have to crack the sending of variables ... ie to give a servo an exact location

Propellor Web Server

I have been battling for over 1 year to get a standalone simple webserver working (Arduino Based) ........Failed.

I have been battling for over 1 hour to get a standalone simple webserver working (Propellor Based) .....Total success.

okok maybe if i go back to the atmel version i am armed with more information.........


Its been a dream of mine to get an Internet controlled robot up and running - using its own dedicated Webserver.

POV (persistence of Vision) from Hacked "Aircraft carrier marshalling light"

Take one Aircraft carrier marshalling light ..... or something you can pick up at the local supermarket for 10CHF(10dollars) like i did.

Hack the living daylights (joke intended) out of it.

Result =  4x8 neat LED rows..........plus a neat battery box,enclosure and strong magnet (for another project)

With a dremmel cut the positive tracks and expose some of the copper track

Mysterious Tracks Appear in snow !!!!

Whats happening on Gs balcony ?

Off the track :- i need to ID this car and its year of manufacture - if anyone knows then please post a picture here and i will add you to the unofficial sponsors list........ really i am serious.

(But wait a moment - this project needs an MPU & motor driver - but which ones - what would you official sponsors send me haha)

I would like to reproduce this exact set up.........

Propellor :- "Major Nichols" hits the Rollers - laser wheel encoder (Part 5)

One Etape closer.........

Decided it was time to try out my "Laser wheel encoder - Propellor Rig" with my actual racing bike :-

Starting to get the hang of the Propellors Display Gui.

Sporting in chronological order

Propellor :- Laser Roller Install Part 4

Permanent install of laser/photo transistor brackets and circuit walk-though.

As the laser needs to be pretty "Solid",  i decided to install it using metal brackets.... so ......

..... it aint gonna move and miss-align whilst i hit 60Km/sec


Propellor :- laser spoke detector "Interactive Roller Experience" Part 3

Out with the reed-switch in with the lasered 32 spoke detector.

What this means is instead of 1 pulse per revolution of the wheel .....i have instead 32 (one pulse/spoke) ..... meaning a much faster update of my speed.

Video explains the details...........

Propellor :- "Interactive Roller Experience" Part 2 Display Gui

nonstream link part2 Display Gui

At last i have cracked my Propellor/Spin Display Gui headache using a combination of the tv.spin and graphics.spin   object files.

The basic "Speedo" stage is complete giving me a much more satisfying digital and analog gauge to watch (already 1-up on the traditional cycle speedometers).

Propellor :- "Interactive Roller Experience Begins" Part 1

So the Build has Started.........

My first real dive into "Spin" Processing.......... using an "EasyProp" propellor board........

Its been an interesting week learning how to setup input and output digitals , also setting up the Monkey-tasking was a bonus (i just love MT now - sorry Arduino :-)

It was also a simple task to set up the Video output to my Dispaly Gui that will fit onto my bike.

My brain hurts from trying to understand the time_ing and crystal settings and multiplyer constants.....
