Low-power remote power-independent (solar charged) sensor node!

Well, for a while now I've been entertaining the idea of building a remote sensor node to keep track/record of my indoors "balcony orchard".

This project here will be my starting point, a Low-Power Wireless Sensor Node where most of the work is already cut out for me.

It's power consumptions are reported to be:

Sleep Consumption 0.14 mA

Price: $2.35 USD

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.

question on a h-bridge circuit I found on this page

Hello everyone,

well, I´m pretty new to this community and I hope this post is not too dumb in your eyes. I´m more at home when it comes to computers but as soon as I get into contact with circuits and means to make a computer sense the "real world", I thought about giving it the opportunity to drive around next to other actions. In fact I´m trying my best to deal with microcontrollers and learn by doing.

Make robots talk.. to each other.. dirt cheap!

I have this thing in the back of my mind that "the next step" for me must be my robots talking to each other.

free 2d CAD

Hi.

Since secondary school, I've been using a student version of the cad package they use (2d design). However, it is awful, and is even more so now I've left, as I can't;

It's been a long time since I put up a new project, and I felt that I should from today onwards post all projects which I make since I've actually some other … Read more

Wild Thumper Controller - Packaged Software has Issues

If you are trying to used the Dagu motor controller with their Wild Thumper vehicle, which is great, but can't get it to respond properly to a RC tranmitter, make the following changes to the software. Get off D0 and D1 and move to D9 and D10, which are PWM channels. You don't want a PWM repetative pulses (every 22ms from a Spektrum transmitter) to clobber your serial interface when loading programs. This is why you get a sync error from the compiler if you follow the manual.
