Etching for Artists and Hackers: Printmaking & Circuit Boards
I recommend clicking on the menu button to view as a full screen presentation.
These slides — from my talk at the 5th Skullspace Hack-a-thon — explore the history of etching, intaglio printmaking, and the etching of circuit-boards. Etching is the process of using corrosive chemicals to cut into the unprotected parts of an object’s surface.

Chemical Etching For Artists and Hackers
This Saturday (April 16th) I’ll be giving a talk on chemical etching at the 5th Skullspace Hack-a-thon.
Etching is the process of using corrosive chemicals to cut into the unprotected parts of an object’s surface.
Etching has both artistic and industrial uses. I have experience with both types of etching and I’ll be sharing my knowledge of:
- The History of Etching.
- Etched Copper and the Printing Press. (Printmaking)
- Etching Circuit Boards for Electronic Prototyping.
I’ll see you there.
In the meanwhile, check out the etchings of my father, Allan Geske.

“Although its origins are more distant and obscure, our writing may be said to start with the Greek alphabet from which the Roman letters that make up the alphabet used in the west today derive. The Greek scripts read from right to left and left to right alternately.”

“Permission is a scarce commodity in this land of multiple freedoms.
As a teacher and as a mentor I give people permission to be who they want to be, and sometimes I think: How did I get stuck with this job? Isn’t that what our schools are supposed to be doing? The answer, I’ve found, is that most Americans look back on their education as a permission-denying experience–a long trail of don’ts and can’ts and shouldn’ts.” — William Zinsser

Join SkullSpace on March 19th for their fourth hack-a-thon.
“SkullSpace is a whisper of a hackerspace in Winnipeg. SkullSpace is a place for hackers, builders, programmers, artists and anybody interested in how stuff works to gather in a common place and help focus their knowledge and creativity.”

TEDxManitoba Analogies
Last month I had the opportunity to attend TEDxManitoba, an independently organized TED event at the Park Theatre. It was a day of inspiration drawn from the various speakers and the conversations with fellow attendees.
During each of the seventeen talks I scribbled down my thoughts in a notepad. During the week that followed, I tried to distill each talk down to one compelling analogy. These seventeen analogies are presented below (in italics), along with links to each video (follow the arrows).
Some of the analogies are direct quotes, others are summaries of what I personally took away from a talk. Out of context these analogies may have little meaning, so watch the videos. I’ve marked my favourite talks with a star (★).

The Kirkbride plan for mental hospitals consists of sets of enormous, symmetrical, staggered wings, like a bat made out of lego. Men are on the left and women on the right in sections that radiate from the main entrance for increasingly violent or incurable patients.
Early mental institutions where patients had to pay for their own incarceration would also vary in class (rich to poor) on the y axis. The staggering of the wings ensured the flow of air through each, purging them of diseased vapors perhaps, such was the Victorian obsession with fresh air.
