Printing with trimmer line

As many of the shout box regulars have found out i have my printer up and running. when i finished it i had no material to print with and a massive desire to see my monstrosity work amd remembered something i had read online.People were experimenting with trimmer line (the stuff thats used in weed wackers/weed eaters etc...) but last i had looked into it deltas and bowdens were the new and most people were running 3mm filament. well after looking around i found .065 inch line which measures out to ~1.68mm.

Soldering tutorial

Hey there

When first starting out on electronics, I found soldering really frustrating, mainly because I was missing a few good tips and tricks that make it a breeze! So I've just finished off a video tutorial, and thought I'd post it here in case anyone finds it helpful :)

Arduino and a Chinese 32 channel servo controller

I bought a Chinese USC 32 channel servo controller on ebay a month ago. Last weekend I finally found some time to try it out. But I can not get it to work with my Arduino Mega, actually I thought there was something wrong with the board, unitl I downloaded the Chinese software for it, which lets you test the board. I connected 2 servos and the sliders in the program let the servos move. So the board works when using USB.

Depression

Not many people understand chronic depression. I doubt anything I write here will solve anything, but I think it's important that people recognize the signs of depression and learn to recognize them in themselves and their loved ones.

Most people make the mistake of confusing depression with depression. See, I've just done it myself. One problem for English speakers is that the word for depression (as in a chronic life-threatening mental illness, most often inherited) with depression (as in being sad for a few weeks due to a known cause).

Sugru, New bot building material.

I found this on YouTube and thought it was a pretty neat way to make some strong, flexible, temperature resistant robot parts. All the info is in the video, but basically it is like polymorph, only silicon based. Enjoy.
