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.
This video covers engraving, etching, aquatint and drypoint printmaking techniques.
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.
- 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.
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 (★).
