__NOTOC__&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=Main topic: How to design, prototype and build from scratch a simple, accurate, cheap spectrophotometer, or anything?=&lt;br /&gt;
&lt;br /&gt;
'''The Hackuarium &amp;amp; Octanis team behind https://hackuarium.github.io/simple-spectro/, represented by Océane &amp;amp; Luc Patiny, will explain how they designed, prototyped and now produce a simple, precise, cheap spectrophotometer.'''&lt;br /&gt;
From scratch to cool, Do-It-Together style.&lt;br /&gt;
You do not need a piece of equipment costing several thousands CHF/euros/dollars to teach and learn this great biology and chemistry technique, spectrophotometry.&lt;br /&gt;
&lt;br /&gt;
Any freelancer, entrepreneur, student, project leader, teacher, curious mind can learn a thing or two thanks to this approach. If your last biology experience was around age 14, even better: come to see how different and easy the Hackuarium approach to it and other sciences or arts might be ;)&lt;br /&gt;
&lt;br /&gt;
'''Please, RSVP on Meetup, and share widely on Facebook, for us to be able to prepare the room for you accordingly!'''&lt;br /&gt;
&lt;br /&gt;
&amp;quot;The goal [was] to create a simple spectrophotometer that measures the absorbance of a sample at 3 different light colors (red, green, blue), is autonomous (on battery) and displays the result on a LCD screen.&lt;br /&gt;
The initial idea was that you could teach spectrophotometry without having to buy an expensive instrument, since you can find experiments that does not require a specific light wavelength. This includes optical density for bacteria culture, determination of a pigments concentration in a solution, determination of the kinetic of a reaction and many others.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Smurf candy and its typical blue color might have been involved at some point, but no smurfette was harmed during those experiments.&lt;br /&gt;

==General comments==&lt;br /&gt;
&lt;br /&gt;
Intro to Hackuarium, and: we have moved out!&amp;lt;br&amp;gt;&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
You might have heard we are moving (out, up, any direction you like).&amp;lt;br&amp;gt;&lt;br /&gt;
That's right, we emptied our lab at the 2nd floor of Les Ateliers de Renens, Closel 5, CH-1020 Renens (VD), over the past month. We are still exploring new opportunities for a space, after 4 years in that building where our association, lab, and most importantly, community, were born.&amp;lt;br&amp;gt;&lt;br /&gt;
This is then officially our first nomadic #OpenHackuarium (number 227, that's a lot of Wednesdays), kindly hosted by our now ex-neighbors at the 3rd floor, MassChallenge Switzerland. We voted during our last General Assembly to try and make them a regular contribution to our now past first ecosystem.&amp;lt;br&amp;gt;&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
tl;dr So long and thanks for all the fish, we'll keep sharing!&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
