VOLO - Tiny bright LED's for your Multirotor

Posted on June 12, 2015 at 7:55pm 3 Comments

Check out these tiny little LED's, they look great for orientation or FPV carpark flying.They are only 21mm x 7mm and come in White, Blue, Red and Green.

From the VOLO website...

Unlike any other LED, the VOLO LEDs were specifically designed for multirotors. They offer a bright, tight cluster of LEDs and are available in…


FPV Multirotor Racing :)

Hey Guys, This is a little off topic but it's awesome fun!

I have created a website dedicated to this new sport! (If you can call it that)  :)

To give you an idea of what it's all about I have attached some videos from our first race…

The Devil Ray

Hi Guys!


If you have not seen this yet check it out!


It is the Devil Ray 2.4M flying wing  made by Chris McNair.

We asked him to make one for us to use in the Australian Outback UAV Challenge. And before you ask we have an ATTO IMU onboard!

The Devil Ray has the option of 3 different wing sets 1.8m, 2.4m and a 3.6m. (We have…


Around the world with no fuel!

Hi Guy's,

Way off topic but.... How cool is this!

These guys have built a solar plane that has the potential to stay up for ever with no fuel!!

The will attempt to fly it through the night in the next week or so.

Here is a little video from their YouTube channel.…

Excellent! I am sure you will have some fun. I have the propeller and I just ordered a better ultrasonic range finder that is suppose to be less noisy than say the PING module from Parallax. If you need any sample code for the bs2 just let me know. I might have something....

I just checked out your website. I worked for 3M Touch Sytems until the end of March. If you need any info or help about touchscreens and touch integration into monitors, just give me a yell...We used to work on some projects for home automation, maybe they were yours :) Anyway, you're more than welcome to ask any technical question

Hello, I read through your article, " Help! Can't display NMEA strings with BS2Px properly" and i found it very interesting and insightful, because i am doing a simular project and am also using the same components as you. I was wondering if you would mind posting the final navigation code that you came up with, by that i mean the code that you had when the article finished as apposed to the code you had originally. It would be a huge amount of help for me.

Hi Gus, I'm sorry to say that I never got around to finishing the nav code on the Bs2. I tried it s few different ways but kept coming up with the same problem. The Bs2's limited math capabilities. If I remember correctly it could not do floating point or do the ATN command with negative numbers. You could ping a message to Chris Anderson to see if he finished it but I think once he started to play with Arduino the BS2 was forgotten about (just like me!) Maybe post the question on the forum to see if anyone finished it. Good Luck! I'd love to be spending more time on this but work keeps getting in the way!

I got it working on a BS2pe in 2006. Negative number headaches were why I quickly upgraded away from 8-bit micros. You have to test numbers for the sign bit, and if negative capture that fact, then re-apply required sign after calc with positively-only math. what a headache. I have no idea where my original code is, sorry.

Hi Scott,

The Melbourne DIYDrones group is meeting this Sunday morning for a bit of a fly at the large oval behind the Royal Chilldren's Hospital. I wonder if you would like to come along. I'm entering the Outback Challenge in 2014, and would love to ask you some questions. I'll be bringing my GCS trailer. Blog here:.

Hope you can make it. We are meeting here:

Still figuring out a time, but usually it's 9am or so.

DIYdrones Melbourne group is here:
