We love microchips

- That's why we boil them in acid.

You can now support Zeptobars at Patreon and more

We are running this blog for more than 3 years with no monetization of any kind (advertisements, merchandise and such) but from time to time people kept asking on how to help us. From the other side - we've probably reached the limits of our resources to improve the quality of our lab/imaging setup, and we'll need your help to move further.

We've finally outlined a number of voluntary ways you can support our efforts to produce higher-quality microchip photographs for curiosity and education.

Basically, there are 4 ways - spread the word, send us few cool chips for future work, support us at our Patreon campaign (which would allow you to schedule small contribution for each new die shot we publish) or send us some Bitcoins (or use good old Paypal).

Either way content of this blog will remain free for everyone and it will continue to be licensed under permissive CC BY 3.0 license.
