Modifying picaxe8 proto boards to fit your needs.

Since my projects contain a lot of 08m procs, I decided a while back to grab a couple of the proto boards for for fun and experimentation. With these boards I also wanted to be able t o reuse them after doing some experimenting with them as we all know desoldering can be a chore.

So here are a couple of ways I'ved moded the proto boards.

1. Choped the proto side off of the board, added a set of male header pins and rewired the power lines. Also used the proto side of the board for a 6+v to 5v regulated via ldo reg.

Custom project board in progress...

Hi, I have a spare PICAXE 28x1 and L293D that I want to use for my first custom built circuit. But i have no clue what to do!!! The diagrams on the Picaxe website are so confusing and the ones in the manuals only show the pinouts. Can I just hook up 4.5 volts? Or do I need fancy shmancy support circuitry like capacitors and stuff? 

Thanks guys! 

UPDATE:

I have a diagram of the L293D and it is nice to have, but very confusing.

mini ir beacon

So this is the mini ir beacon I've had mulling around but never got around to building one....or finally built it. I'll post the current code for this in a bit.

The circuit is pretty basic in that it just uses a picaxe, an ir emitter, led, some resistors and a npn transistor. Ialso wanted to keep it small(hence the mini) so decided to use some lr44 batteries to get around 4.5v out. The battery holder was fashioned out of some 18ga colid copper wire which does a great job of holding things together.

Got My New Computer!!!!!

It's a MSI Wind U120 and it kicks the most ass. --Watch the video at your own risk...

TJ snow angels and pulley kebab

tj_banner2.jpg

Today I decided on the arrangement of my Theo Jansen legs on the side of my future robot. I place one prototype on a piece of cardboard and traced the outlines with the legs in all possible positions. Like a robotic snow angel. This way I know what the "footprint" of the entire mechanism against the side of my robot will look like. And if one leg will hit a neighbour when flailing about.

TAG WAR!!!

OMG, I just realized that the tag "Picaxe" was third, Under both Arduino, and even the silly tag "Robot"!

So, I am now re-editing all my robots that use Picaxe to fight evil open source system Arduino!

HAHAHAHAAA!

How to wire a bumper switch

Wire it like this picture and "jump" would be the code that is executed when the button is pressed...

Chemical vise

I have no machine vise, but my project called for one. These pulleys come with a pilot hole. This way you can decide for yourself what kind and size of hole you want in them. I want them tight, 4 mm wide and perfectly perpendicular.

So what is a guy with a jig saw and a drill press to do? Right. This.

Because there are not only robots in life...

...i wanted to show some of my others projects. I made them few years ago...

First, a clock, featuring... me ^_^

And something different, a short movie from the time i was doing mountainboard and at the same time was discovering special FX.

Hope you'll enjoy!

You guys are my heroes!

I am all emotional, so maby I should not be writing this :D

However: Life is treating me in ways that makes it impossible to have almost any time on LMR or in the workshop these days.

It has been really bad for some months, and I sort of drifted off, silently accepted that I cannot do everything that I want in life..

Then tonight, one friday night where I finally got a little time, I enter this amazing site, and wow.. You guys are just going on, all is the same, how cool!

I am so glad you are all in here still :D Thanks!

New Project?

Just found some tracks off of an old toy... What do you think of this:

Plus this:

And get this?

What do you think?

 

 

Fun with timers and interrupts on Atmel Tiny26

A long time since my last post on this site... Anyway I've been experimenting a little with my Atmel Tiny26 uC today using AVR Studio 4 for development and the AVR ISP mkII programmer to program the uC.

LDR Cyclops - holding, scanning, seeking, recalling

Continuation from here.

Video straight from the camera to Youtube (Sorry Oddbot).

Octopus IP soft robot

This here could be interesting for the LMR-Community: The Octopus IP is a "soft robot", that uses a principle derived from the muscles of an octopus. It's made of rubber and strings - and it looks extremely sleek. The research for the Octopus Project is funded by the 7th FP of the EU. But, yeah. It should be also possible to assemble this at home for the freaks!

3x08M

This will eventually become a robot project, but because my progress is so very slow, I decided to post the bits and pieces I have as a blog. That way you guys can start commenting and I get to show my pretty pictures.

The bot I'm working on will combine some of the things I allready posted as walkthroughs. Mainly it will feature the mintvelt object tracker and inter-picaxe serial communication.

Free Range Robots (IR Beacon) **UPDATED**

**Update 4.14.09***

OK, when you watch the video... 

First of all, it is like, 5 minutes -sorry. There is a point though promise, and that point starts at about 3:40 or so. Now, I can't stress enough, the code is wicked chunky as it was written in about 10 min. It is all "bang-bang" and not proportional at all. The final code should be about 10x faster, much more accurate with a lot less trial and error. For now, this is just proof of concept and indeed it has been proven. 

 

Blinking Bug - Blue Spider )))

Hello again!

This guy is Blue Blinking Buggy )) (made with this tutorial: http://www.blinkybug.com/)

Hi is very mysterious at night )) 

Green powerbot!

This is my another one... Looks better, and faster moving.

 

 

Talk to the hand! Er, gripper?

OK.  So everyone fumbles sometimes in life, and in this blog post with video, I fumble perfectly.

LOL, I'm normally dry and boring but here I'm controlling my phidget arm with my mouse and attempting give it a voice, and character while acting a bit silly.  I fail horribly. tee hee. I'm such a buffoon!

 

Rudimentary LDR eye

Old idea rekindled

This idea about very basic robot vision haunted me ever since I first saw AmandaLDR. Even before it was named after a canine. It's somewhat inspired by the evolution of the first eyes in nature: just a bunch of light sensitive cells on your rump.

Cant get Freeduino to work with Vista

Ive checked my soldering, ive installed all drivers and have it hooked up correctly but for some reason I cant get my freeduino to work with vista. Everytime I try to upload code I get these errors --

    avrdude: stk500_getsync(): not in sync: resp=0x00

    avrdude: stk500_disable(): protocol error, expect+0x14, resp=0x51

does anyone know what these mean? (Freeduino is same as Arduino Decimilia)

Phidget Servo Controls - 2

Am I blogging correctly?  I'm still a little new and a bit confused.  Sorry if I might seem to be spamming?

This is a video of my two controls working together. 

I still have a lot thoughts of how I'm actually going to present a final GUI and functionality, so this is just a starting point. Keep in mind, these are two separate controls. My intentions are to allow people to use my phidget servo control individually and/or use the IK control individually or, both at the same time, with as little code as possible.

new project: 3 servo exapod

i want top build my 3 servo exapod like this one  

http://letsmakerobots.com/node/4947

it have to be half in size

i will try to use polymorph for legs and body

working in progress...

This was my first, now i'm working to upgrade it )))

Thank you guys. Your advices were very helpful.

Polymorph ?!

uh  It could work as a neural network....

 

 

 

 

 

 

 

 

 

 

Torque calculation

I would like to know how to calculate torque on three degree of freedom leg. Example like a Phoenix type robot design. At least show me the calculations that would make my life easier. Thanx

Hi, I'm still here!

I bet you're all wondering, "hey, why isn't Zanth around posting bots anymore?"

Well, truth be told, I haven't touched my projects since graduation. Searching madly for a job has taken precedence over everything else. Now that I have a job (!) I decided it would be great to get back into things.
