Let's Make Robots!

OSP

Ok so for one i moved it to a blog and two it now has some different functions.

The first thing i added was a password. In-order to get to the main menu, you have to type in a sequence using the input buttons.

The second new thing is the distance feature. I sat down and changed the sharp's numbers to inches and figured out to what extent to change the distance to the next one. It is pretty accurate but only goes up to 12in and down to 4in.

Controllable battery charger based on max712


18/02/2010

Well here it is!! My attemps at building my own battery charger using a sample of the max712, here is the original post that inspired me, http://letsmakerobots.com/node/9272 and special thanks to ezekiel181 !!! 

The Sparkler

Recently a funny robot idea came into my mind - The Sparkler.

What does it do?

The Sparkler is a tank track robot. It drives around and waits till you clap your hands. If you clap your hands, it puts a sparkler out of its container (similar like a quiver for arrows), lights it off, waves during the sparkler burns and throws the spent sparkler then away. Yes, defenitely outdoor enviroment is recommanded. And I rememeber now, Picaxe has the music tone playing option "Happy Birthday". What a birthday surprise!

Minimal Picaxe LED blinker

I just found a different way to make an LED blink with a picaxe 28x1:

main:
   inc b0
   let pin7 = b0 >> 7
   ' do other important stuff here
goto main

Pong

Do you remember when you were a kid, and you spent your time playing pong? Neither do I. But why not bring it back? Yes a portable pong game. 

So i set out on my quest...

After some decisions, i decided i would make a pong game using 6 LED matrices, 6 MAX7219CNG, 2 potentiometers + KNOBS!!, and some custom PCBs. So here is where i am at so far, just have a collection of parts but im working on it, still waiting for the PCBs to arrive. 

 

Maker Faire - Editors Choice - Cheapduino

Maker Faire in San Franzisco. I could not be there but still got something on my desk this morning. 

Yeah, that's the Maker Faire Editor's Choice banner, given for the DFRobot's Cheapduino and signed by Andrew

Making parts

I spent Thursday night making hubs for new robots.  Enjoy the video.

Jinnarin's third robot (YDM clone). (Updated: 9-1-11)

Hi all. I have been away for some time (health reasons), but I am finally back and starting on my third robot. You can see my first robot here and here, I never made a page for my second robot, as it was just a remake of the start here robot (maybe it will make a special appearance).

Thanks for a fantastic time at the Campus Party Berlin 2012

Thanks for a fantastic time. You are all very giving and really, really cool persons. And very talented.

You know who you are.

Everyone else; Since Campus Party is a returning, and starting to be global -event - why don't we use it as our way to meet IRL?

Hope to see you next time, next place :)

Testing the wheeled version

As announced in our previous post, we are working on wheeled version of our robot. Tires and shaft adapters are arrived today and we mount them to conduct first test drive. Here are some photos:

Servo Power Gearboxes - revamped


We have recently revamped our line of Servo Power Gearboxes! Our gearboxes have always been top-of-the-line and super powerful (up to 3,402 oz-in of torque!) but now offer upgraded features and a more durable construction.

Theo Jansen style robot leg: prototypes #8 and #9, I suppose

My Theo Jansen Leg is finally starting to become something reproducible. Every step in in this arduous journey has been aimed at reproduction. No robot needs just one leg. And also, I wanted to share my design with anyone who fancies a walking Strandbeest robot.


Update 25 feb 2009: New video demonstrating the first powered test. Maybe that should read overpowered test...

(The ugly green screens are an editing artifact. Imagine beatiful fades.)

Going to Spain :)

Hey, I was just invited to come to

CAMPUS PARTY EUROPE

Wehee.. Is any one else going? See you there :)

They asked to see YDM, but I think I will have to make a trata-version of it! Huge sticks and amplifier!

(Yes, I am a one hit wonder, apparently - but hey, a hit is a hit! :)

Looking for Feedback on PICaxe Platform Module

I've been working a PICaxe platform module.  I did a V1 a few months ago, and recently re-did it.  Here's a prototype of V2;

I've used the same power stage as the Propeller Platform sD - it's 5v @ 1.5A and 3.3v @1.5A with an extremely low dropout of 100mV.  Standard power and programming jack, and it has power indicator lights.

I need to make a few changes, so I thought I'd get additional feedback.
