Within the relative chaos of my domestic arrangements, I have one small oasis of perfect order. One thing that I can call 'organised' and 'fully functional'. One thing that I can touch and know that it is reliable and ready for action at a moments notice - and that is my wonderful home made Hackable Arduino Prototyping Board.

This vaporisation project was initially envisaged to be a simple fumigation machine for beehives, but very quickly got completely out of hand and developed into so much more than that. Indeed, people are now flocking from all four corners of my island to witness the amazingly performance of this machine as it sits in the centre of my living room vaporising all manner of exotic substances, including frankincense and cheese.

Back to December ...... It is Winter 2015 and Sussex university has just published a report that concludes that vaporising oxalic acid is the best way to treat honey bees for the varroa mite. I must therefore build my vaporising machine immediately. There can be no delay .......... I wonder what else I can vaporise?

The varroa is a tiny 'mite' that lives on honey bees and in their brood cells, sucking the bee's blood for nutrition. It is not particularly harmful in itself, but it does carry some very nasty diseases which are very harmful to the bees and can cause complete destruction of the colony if kept unchecked. I must act now to protect my bees.

The treatment for varroa must be performed in the coldest part of Winter, when the amount of brood cells in the hive is at it's minimum as the mites can hide in these cells and completely avoid the oxalic acid vapour. The report was only released on the 17th of December and so the pressure is on for me to build my fumigation machine before the bees start to produce more brood in the early spring.

Fortunately, I have a whole load of electronic bits and pieces left over from previous projects, so with a bit of hunting around in my untidy workshop and unsoldering of a few components here and there I was able to build this project in time for the coldest part of Winter to arrive.

Apart from my illustrious hackable prototyping board, this project was very much designed as I went along and I made no drawings or sketches before hand. I drew the main vaporisation chamber in Fusion 360 as this was the most esoteric part of the design. Much of the metal tube and plate was picked up off the workshop floor or found in dirty rat infested boxes leftover from months/years/decades gone by.

I am so pleased with the end result that the machine now doubles up as a coffee table in my lounge. Occasionally, if I am 'in the mood', I press the 'on' button and vaporise something, sometimes just for fun and sometimes to fill the air with exotic perfumes. Surely, this must be the most ridiculously over engineered air freshener ever built?

Step 1: Introduction

This Instructable actually has three major parts to it:

  1. Demonstrating the features of the prototyping board by doing an actual project on it.
  2. Using and coding an Arduino to control a potentially hazardous process and produce warning sounds.
  3. Building an electrical heating device to vaporise and inject chemicals into a beehive to kill varroa mites.

Most likely, specific parts of this projects will be useful to people, like how to use resistance wire to build your own heater and how to control a hazardous process using an Arduino. But most useful of all is the prototyping board and, yes, the files are included for building it yourself - you just send the files to Hong Kong with a few dozens of dollars and they post you back a stack of boards. The boards have even been thoroughly tested and debugged so you know they will be perfect.

<p>Take this device to Amsterdam and load it with whatever you can get over there, you're gonna make a lot of friends! And no, we're certainly not talking cheese...</p>
Ah yes, there could well be some 'medicinal' uses for this gadget. It has been suggested that it should be miniaturised , with all the NASA sound fx played at the same volume. I'd have to make a smaller PCB etc. but I'll let you know!
<p>This leaded my mind to those famous Nepali honey-catchers who collect the even more hallucinogenic honey from wild bees. Rhododendron-pollen &amp; nectar is what those bees use to make their fuel! Maybe you should plant some of those shrubs on your island? Vaporizing rhodo-honey, th&agrave;t's the next step my friend!</p>
Good idea! But the locals would not be too keen on the idea I think. However , there is rhododendron growing wild and free in the foothills of the nearby Eryri mountains and some beehives could possibly be relocated to collect the special nectar and pollen.
<p>Are you serious? That's great news, really! Here's a crazy video about that 'mad honey', I'm sure you'll like it. Just too bad I didn't know a clue about this topic in 1998 when I was in that country - I only had beer &amp; rhum to set my spirits free.. Enjoy!</p><p>https://www.youtube.com/watch?v=Y_b2i_FvYPw</p>
No promises! Great video btw - must get making my rope ladders and bamboo honey filters . Ps. Still trying to get my neighbour's goat to eat fly agaric mushrooms, but no luck so far :(
<p>Not all rhododendrons are created equal. Bees won't touch the flowers here in the PNW with our variety because the nectar is toxic to them. It isn't to the native bumble bee though.</p>
It's lutium and ponticum that makes the famous mad honey. There are our some rhododendrons growing near where I live, and sometimes the bees come back to the hives with bright Purple pollen attached to their legs. I have not noticed any hallucinogenic effects from eating the honey though. I probably need to eat more of it to test it properly.
<p>I had no idea that bees can have mite infestations! Now I wonder if fleas could have mites? Wouldn't that be a wondrous thing to start eliminating undesirable insects with other insects instead of poisons?</p><p>Thanks for the Instructable! I don't have a use for it yet, but if you make an Arduino air freshener for the bathroom, with its own sensors to identify when its needed, that'd be a big seller!</p>
Actually, bathroom, shower rooms etc is a big problem in terms of humidity, ventilation, smells etc. I was talking about it with an architect friend recently and he said many people block off ventilation ducts as they are too crafty in winter. What is required is humidity sensors and actuated ventilation valves and fans. Also active dehumidifiers would be useful.
<p>fabulous!</p><p>The preliminary project planning with the imaginary boss was so true to life, I could almost hear it being spoken... I just wonder what this boss looks like, after having a look at your very admirable avatar. He must be one tough cookie to pull a shotgun on the likes of you! I'd really love to see your workshop too... Perhaps an instructable on how to put such a place together would be in order.</p><p>Really, great project, and I love the presentation 'style'!</p>
<p>Hey Bruce! I don't think it's tough to pull a gun on someone like this. Brian has a lot of issues and has been too busy pursuing power and money to deal with them. Instead, he has to resort to violence and intimidation to maintain his fragile grip on reality. Maybe some more about Brian in future Instructables?</p><p>I promise you, my workshop is fairly messy and I will leave that to your imagination!</p>
Great project. How does the exposed circuit board fair in the elements, and are you planning on weatherizing it? I see it has potential to be used in not the best weather. <br><br>Regards,<br><br>BMan<br><br>P. S. Why does every great project have to bastardized for getting high? LOL. :)
Hello Bman. I'm not planning to weatherise it as it looks cool like this in my lounge. We did fumigate the bees in light rain though with no ill effects. <br>Not sure where the whole getting high thing is going!
Totally cool - love it
Thanks!
A great project! I did learn something about bees and acids but it's a dangerous machine...
<p>Thank you for your comment. 'Dangerous' is an emotive word. Is a car dangerous? Yes potentially. What are the risks?<br>The photo attached shows a vaporiser used in a dangerous way, as the beekeeper is directly exposed to acid fumes.</p>
Great project! Love the proto board.
Thanks Thinker!
Great project! I love the saftey features! Many of the projects on here seem mildly sketchy. How long was the total build time? <br><br>Have a great day! :-)
Hey thanks just4fun! I think it took 18 days total. Nothing particularly difficult. Lots of fun though!<br>Ps. I did not know about the sketchy projects . I presume mine is not one of them?
