Du du kuglica sajica mavrica

What
After 10 days NanoŠmano collaborative exploring and experimenting on various topics of Šmall Matter, we developed short "du du"s (workshops) to introduce some basic DIY-projects and ideas on nanomaterials. We now want to share this through a set of parallel mini-workshops on the topics of kuglica, sajica and mavrica. Space is limited to 3 participants for each topic. Thats 9 in total :-)

When
Saturday, 30th, 14-17h

Where
NanoŠmanoLab, Mestni trg 15, Ljubljana

Descriptions
With the “du du“s we share our experiments by doing little DIY nano projects for interested artists/hackers/tinkerers. The topics, kuglica (particles), sajica (soot), mavrica (rainbow) cover some of the aspects of nanomaterials, such as their form, size and visibility in a microscope (kuglica), or their use as gas sensors based on carbon nanostructures in soot (sajica) or detection of various absorption phenomena with UV-vis spectroscopy (mavrica).

Kuglica


Level: Beginner

With Boštjan Leskovšek (SI)

Sajica


In this workshop we will build a simple circuit on a self-made pcb. It has an oscillator and a resistive gas sensor self-made out of soot aka saje (carbon particles). The output be both a blinking LED and also a speaker that produces sounds when you breath at it, put alcohol next to it or other changes in the gas around it. And it will sound cool when you attach it to a proper big amp :-)

Level: Beginner

With Borut Savski (SI) and Marc Dusseiller (CH), inspired by Prof. Gorazd Planinšič

Mavrica


The use of visible light at different wavelengths (mavrica / rainbows) is a great tool to detect various properties of a system. For example looking at the absorption at specific colors (wavelengths) can be used to detect chemical reaction products, composition of stars or the presence of silver nanoparticles. In this short introduction we will build a simple DIY spectrophotometer using an old broken cd-rom and some black cardboard, which then projects a small rainbow (spectrum). Buy putting different materials between the light beam you will be able to see the absorption bands. To digitally measure these one can use simple light-sensors/arduinos, hacked line-scanners, mobile phones or webcams. As a more advanced workshop, we like to invite professional artists/hackers with a background in physical computing/coding to join the workshop.

Level: Intermediate

With Bengt Sjölén, artist/hacker (SE)

Who
Because there is limited space for participants available, please register in advance by sending a mail stating the topic "kuglica, sajica, mavrica" to [mailto:delavnica@ljudmila.org delavnica@ljudmila.org]; but you're also welcome to just come over and join in on site in the NanoŠmanoLab, if there is still space...

Participation costs
To cover the material costs for the workshops we charge a donation between 5€ and 10€ up to your budget. Please bring during the workshop.
