Why is Avoccado° spelt like this?

We spelt Avoccado° with two C’s for Creative Commons. Similarly, the small ‘o’ at the top right of the Avoccado° logo (where a copyright symbol would usually be) is for ‘open’. This is an idea inspired by Apertus°, the makers of the first Open Source movie camera.

Here you can read more about how Avoccado° is a crowd-sourced name.

What licenses have you used for Avoccado°?

Avoccado° is not patented or registered as a trademark. Everything about Avoccado° is free as in libre and Open Source. The licenses don’t require any permission for use. The code is mostly MIT, while artworks such as the Avoccado° logo and this website are CC-BY-SA 4.0. Please check the Avoccado° GitHub repositories for more licensing information.

I’d like to contribute to the Avoccado° software or hardware

Have a look at the repositories and go ahead. Open issues, write feature requests, fix bugs, or clean up any spaghetti code… we welcome your contribution.

I’d like to fork the project

Yeah, go on! Just remember to make it Open Source. We might fork your fork again if it’s good. One thing though: you’d have to give the product a unique name so that it can be distinguished from the original Avoccado° version. This is just like Arduino™ handles it.

I want to make my own boards for personal use

Have yourself a good time. Feel free to show off your fork in your social media circles and link back to us.

I want to make my own boards and give them away to the public

That’s lovely, go for it! If you’re going to go public please follow the licenses under which the original sources are released. In short, if it’s OSHW and CC-BY-SA, then you should release it under the same license.

I want to make my own boards and sell them

Not thrilled, but go ahead. The licenses are not restrictive and you may make your own product, sell it and make profit without paying a single cent to the founder or anybody who contributed to Avoccado°. That includes non-derivatives: you may also just fabricate the original circuit boards and sell them, like literal copies – except for the name.

If you think that it might not be fair to sell another person’s product for profit, then we think you are right and maybe we can agree on a fair deal there – simply get in touch with us. However, Open Source should not be restrictive and thus we chose a true libre Open Source license so anyone may fork it for any purpose. In any case, we’d love to hear about your ideas – a little coordination and planning can go a long way. Of course, if you’d rather go it alone, you’re free to do so. The licenses under which the designs are released don’t require any permission for use, you don’t have to ask anyone. We’d still like to hear from you about it, so we know what’s out there.

What are the hardware & software requirements to program Avoccado°?

You need a computer (Linux, MacOS or Windows) and a serial connection (any USB-to-serial adapter cable will do). Download the latest Arduino IDE and all the necessary libraries.

How long does the battery last?

Current consumption in standby is as low as 0.1698 mA or about 0.00054 W – that’s five ten-thousandths of a Watt.

The average consumption for an active Avoccado° system without vibration feedback or LEDs (that is sending a continuous data stream of user inputs) is 23.32 mA or about 0.08 W. With one single cell of a 18650 LiPo battery you will have around two years of standby time without needing to recharge, or five days of continuous user inputs before you’d need to connect a charger (or place it onto the Qi-charger, if your Avoccado° has got a Qi receiver). If vibration feedback or LEDs are added you will certainly have a lower battery run time.

What is the range of the wireless connection?

That depends on payload length, wireless pollution, obstacles and the material of the enclosure. The Avoccado° antenna has a range of approximately 30 metres with a free line of sight and approximately two to three rooms indoors.

With PA-LNA (Power Amplifier and Low Noise Amplifier) wireless modules that have an antenna  – like your WiFi access point – the outdoor range is up to 1 km and the power consumption when actively sending can be as high as 126 mA, whereas the tiny PCB antenna modules use a mere <25 mA.

What about the wireless energy… is Avoccado° safe and legal to operate?

Absolutely. Avoccado° is legal to operate in every country because of the very low wireless power it sends and the open 2.4Ghz frequency it uses, just like Bluetooth and WiFi. The packet length is very small at a very low power of 1 mW. Avoccado° only sends data over the air when necessary.

To compare, your phone can send 2000 mW, and a WiFi connection – which is basically always active when the router is broadcasting its name (SSID) – sends a maximum power of 200 mW. Any local US radio station may be broadcasting with 100,000 W = 100,000,000 mW for 23.93 hours a day, seven days a week. The BBC has a radio station in Tacolneston (UK) with power of 250,000 W and there are stations with as much as 8,000,000 W of ERP (Effective Radiated Power) like this Swiss one.

How is Avoccado° funded?

Avoccado° is self funded. We try to be as economical as possible and to grow organically. Therefore it is usual for us to build our own fixturescut solder stencils and populate the circuit boards by hand. Many of the parts used for early Avoccado° prototypes were sourced from Alex Shure’s previous projects, etemu prototyping, and from friends at local hackspaces.
