Misc / the recreational drone registration rule is dead
« Last post by Admin on July 03, 2017, 01:52:50 PM »
I'd like to share this email I got today from the local drone users group:

---
The recreational drone registration rule is dead, at least for now. Today, the court has issued its final order implementing its May 19th decision to vacate the Registration Rule for model aircraft.

If you wish to delete your registration and receive a refund, please see this FAA web site for a refund form you can mail to FAA:

If I had an RGB LED I'd start with this circuit.

Electronics / Help needed-4 Pin RGB Cathode LED
« Last post by ToyhackRobotics on June 22, 2017, 09:29:55 PM »
Hi everyone, i've been building my humanoid robot for a short while now, and at the moment i'm having a very hard time trying to successfully have 2 of them work in sync for they are the eyes for my robot.

I have 3 digital out pins on my robots brain, so i thought the 4th pin remaining would need to go to a ground source?

When i tried this i never had the color sequence happen with the 4 pin cathode led, with a simple 2 pin cathode rgb led they work great, but has been impossible to get them to sync.

On my rgb led's i have red, green and blue.

I'm using the ez-robot ezb4.

I'm not good with electronics, ive looked at google images and have trouble making sense of them, i can wire up simple things, etc but have never done rgb led's before, and this is my first robot so also new to robotics and programming...and currently using Blockly for my project.

Any help would be greatly appreciated thank you.

Mechanics and Construction / Re: Actuators too small to simulate human arm?
« Last post by Michael7S on June 20, 2017, 10:10:24 AM »
For now I've used a spring assist for the first 2/3 of the travel.  The last third is pure drop.  This approximates the human propulsion, though a light spring for 100% of the travel might be a touch better.

If I do go to actuated propulsion (and lift), the specs will be much clearer.

Thanks for your help so far.

Did you get this sorted out? I agree with the above comment. Pneumatic is probably the way to go
