View ArticleSingle RF transmitter receiver pair
Hi, I am a novice interested in building a RF transmitter receiver pair. The transmitter would need to single when a variable resister goes low (or high?). The receiver would go high and switch on a...

@InterestedParty You could certainly build such a thing with an Arduino-like product that is smaller than an Uno, but we don't have anything ready-to-go / off-the-shelf that would suit your...
View ArticleAre the schemas of the AQE2 open sourced?
@dariosalvi78 yes Air Quality Egg is an Open Hardware / Open Software product. It's a complex product with many boards contributing to its overall design, and many of these boards have had a few...

thanks for your reply.I was curious to see the NO2 sensor as I was trying to integrate one myself for a small-community project I have in my area. I would be very glad to exchange some design...

@dariosalvi78 Sure, the NO2 sensor we are currently using is made by SPEC-Sensors. Here is a link to the raw sensor's product page. I've attached to this post a PDF of the current (slightly...

Hi, thanks very much! It all started a year ago or so when some neighbours of mine were worried about the quality of the air of the area I am living in. I have no experience with pollution and...

Are the schemas of the AQE2 open sourced?
@dariosalvi78 yup, version 2 uses completely different sensors, we've learned a great deal since we started . Calibration is the hardest part for sure, but I think we have a pretty good handle on it...

Hello. I am super new to Arduino and the entire culture of microprocessor environments. I have learned some hard codes in the past (PHP, Linux, CSS, etc.) so this code language shouldn't be too hard...

Hi @breandanmcewen9. So what you want to do is receive and process RC input and then effect Servo motor output. The closest example to doing this that we have is the Omni-wheel robot, which uses the...

Hello and thank you for the response. I believe I understand the points you are making, and I will research this information you have offered. Do you have a literal example of this sketch (a real...

@breandanmcewen9 sure, I just whipped up this simple example that you can use as a starting point. I haven't tested it (and probably can't find time to anytime soon), but I'm reasonably confident it...

Yes that makes perfect sense and thank you so much. I totally grasp the concept of PWM on RF carrier channels as well as the pulse timing signal conversion to servo action. Can you believe that my...

My Results: A - Six micro servos are hooked up to proper pins per instruction card.B - USB remains connected to Arduino during operation and Serial Monitor window up to see channel activity.C - 11.1...

Holy smokes, no pun intended! Taking this all in... the only way I can imagine something like the catastrophic failure you've described happening is a short circuit or an over-voltage condition...

Thanks for the note back. The Tx and Rx are bound properly, this I am sure of after so many years of r/c. The serial data read is not showing reliable results on one of the two channels (1000-2000). I...

@breandanmcewen9 thanks for the follow up as well. I'm going to put this on my To-Do list, I just need to find the time and piece together a demo. If I learn more and/or get a demo running, I'll...

Great man, much appreciated. I agree entirely that I should inevitably advantage the power isolation features of the motor shield. I was originally in "quick test mode". The reality of this conundrum...

So we have 2 eggs, both v2, and neither one is reading NO2. I'm getting between 1-14 as a CO reading. How can I calibrate the eggs? Do they need to be sent back?
