Last week we etched circuit boards in Circuit Design class. We had the choice of etching with acid or vinegar. My partner, Danara, chose acid while I tried with vinegar. Here’s what happened. The star design is Danara’s.
Printed our designs onto blue paper to be transferred onto the copper.
Soaking in water.
Danara’s board in acid. Mine in vinegar, with a dash of salt.
Danara’s board looked great, especially after it was tinted. Mine didn’t come out so well. womp womp
Vinegar took a lot longer. Because we had a couple of boards using the same container of vinegar, the residue from one board would float onto another board. Danara had her own container of acid, which did a super clean job. I may try again with vinegar, one day. For now, I’ll do over with acid.

Benedetta had mentioned a couple of cool projects in the last two Towers of Power classes that I wanted to check out. So I took this opportunity to research these projects along with a few others. It’s apparent that there are a vast number of things that we can make with open GSM. Though their purpose are mostly different, I noticed some recurring themes based on how the technology is used. Here are a few of them.
Text to control something
Digital Ding Dong Ditch
Various text to open door projects, such as this one
These projects are pretty fun. I think texting is a very human way of communicating. Unlike pressing a button, texting to get a lifeless piece of object to act seems more entertaining and magical.
Interaction through calls and texts
Tinder on call
Campaigns that you can call or text to interact with a screen or poster
The user interact with a less tangible counterpart through their phones. These projects are more game-like.
Anything can be a phone
Hub’s project Jeff
It’s really cool that the GSM Module can be used to create new gestures to communicate.
Insular mobile networks
Burning Man GSM network/openBTS
These applications target issues of not having signal in disaster scenes or remote locations.
GSM Network Jammers
Lady Ada’s Wave Bubble
Julian Oliver’s No Network
Allison Burtch’s Log Jammer
These projects are more on the offense, using the technology to attack itself or those using it, all the while sending a strong statement?
Intercepting or changing data
Julian Oliver’s Newstweek
This is also on the offense, but with more covert attacks.
Remote tracking and data collection
Delivery for Mr. Assange
Stories of Trash
These projects are longer term and requires continued documentation or a fully built out platform to display or visualize the information.
What are ones that I’ve missed?
