Let's Make Robots!


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!

SED or Smoke Emitting Diode

This is an attempt to record the very edge to which an LED can be driven. A failed attempt.


I tried to post this as a component page, but it would not take embedded video...

The LEDs I tried are rated at 30 mA maximum. The forward voltage is between 1.9 and 2.1 V. I used a power source of 8.1 V  and a variable resistor in series that could range from 5000 to 0 Ohm.

scientific zealot or teaological fundamentalist?

With regards to the idea of measuring resistance through water.

I started wondering if resistance could be applied as a measure of the brewiness of an infusion.

And in style with the "I can do science me" segment of "Brainiac", I will cut to the answer straight away: Nope! Is not doable.
