How far can you get in parts hunt?

Just an hour ago I have disjointed this little peaceful innocent birdy, just for a little switch as I ran out of them and did not want to stop my robot building proccess! I'm a feelingless monster...

The question of the day:

How far did you ever get in robot building fever? What dirty deeds you did and what sacrifices you put on altar of robot building?

:D

HOW TO START?

       Hello, Well basically i'm a graduate with biology as my core subject. I had absolutely zero Knowledge of electronics but have now managed to know a little bit from this wonderful website. Please suggest me some refference ebooks for basic code programming.

       I also have a broken RC toy car with two functional motors and an SM6135W microcontroler on its circuit board. Unfortunaltely I couldn't find its remote control. 

       Please feel free to suggest what I can make out of this as my first robot. 

Nonbots in the robots section - "tisk tisk" or "boo woo"?

Should we ban all nonbots from the robots section? You know: robots that are not. That do not even exist? Ideas for an upcoming robot that only exist in the maker's mind. Maybe on a scrap of paper. Maybe the materials are "in the mail"?

I really don't like it when people post such projects. I don't care if the robot turns out to be really awesome real soon or if the idea never comes to fruition. I just feel that the robots sections should be reserved for actual projects that actually have something to show.

What are we, the Nobel Committee?

My 1st non-breadboard circuit :)

I know..a lot of you good folks could solder before you could walk and probably sleep with a soldering iron under your pillow (hope you remember to turn it off :), so here is this guy in his 30s bragging about his first circuit. Pathetic.

However soldering is a major challenge to me and actually the main reason I didn't get started with robotics years ago. It's just not easy for my unsteady hands. So I'm very happy to declare that I just finished my 1st working non-breadboard circuit. It's a motor+servo shield for my Arduino.

Code Repository!

Can we get everyone who has got their code to successfully run to post their files here? Ive been looking all over the site for a central area for code, and I cannot find one. If there is one, point me in that direction, if not, lets all start posting here!

Try not to paste lines of code here, lets keep it clean. uploaded files only please!

What do you guys think?

Some questions from a beginner.

Hi Everyone,

First, thanks for taking the time to read the forum and answer questions from new guys. I know it's sometimes a pretty thankless task, despite being very time consuming!

 The site looks like an excellent resource, and when I have the time I shall read it more thoroughly. In the meantime I have some quite simple questions about a robot that I'd like to build.

Avoid obstacles, wake me up, water the plants.

finding cheap RC ESC (speed controller)

I love RC ESCs. They are electronic speed controllers that you connect to a servo output on a RC receiver or a micro controller, and they give you full step free control over a big motor in both direction. Most of the ones made for RC cars work in the voltage range 6-8.4Volts, but there are several alternatives for people who plan to run up to 24 volt motors in almost constant stall at a gazzilion amps (read robot war contenders).

But I'm the eternal cheapskate, and wants the cheapest there is.. So far I've found this

Build 1 - Please Review!

Hi all, I'm an 18 year old from South Africa interested in all aspects of technology! I hope to enter a Bsc in Computer Science next year at UCT in Cape Town. I am even thinking of going further and doing more afterwards for some crazy reason but thats later.. anyways!

Right so this will basically be my first build from scratch, my own design etc. Being my first build I want to keep it as simple as possible so please comment on anything, I don't mind.
