PCBs

The PCBs from OSHPark came in:

They look great, with the small exception of a trace that for some reason didn’t go all the way to the pin it needed to get to. I looked at the source file, and it looked like I was fiddling with it and didn’t connect it all the way, so no problem. It was pretty easy to patch regardless:

Here’s a video of the boards running blink.asm:

Foraging brainstorming notes

Prototyping — tom on April 8, 2013 at 11:37 pm

These are the raw brainstorming notes from the meeting with Carl and Craig from Concrete Jungle. I’ll sleep on it tonight, and get some test systems planned in the morning. There are some definite next steps in figuring out solid work that can be done to actually detect ripening fruit, as well.

Ordered PCBs from OSHPark

OSH Park offers a low-cost way to get my hands on some professionally-built boards. I uploaded the designs and paid around $20 for 6 boards, receiving them in a couple of weeks. I’m fairly impressed by the speed and cost that these guys offer.

Bicycle prototyping brainstorm

I sat down with Thomas, Mariam, Paul and Andy to think about potential applications for bicycle-based prototyping.

I fixed the issues with the boards and made a new revision. These look like they’re good to go. Video after the jump.

So there were clearly a couple of problems with the boards from last week.

While these don’t work super well, it feels good to get some physical manifestation of this project into my hands. I have a couple of things to try next in order to debug these:

Grid of I/O and applications

This is an early run-down of how different kinds of sensing and actuation can be used to make fairly interesting projects:

Tools as Topic

concept,context,Thesis — tom on February 28, 2013 at 9:29 am

One reason I like tools as a site for critical design is that they’re ostensibly useful. Dunne makes a claim that critical design works to establish counter-narratives to commercial products and palliative electronics, but the problem with the product metaphor is that it commodifies criticism: fine arts have long been a critical “product,” and just couching provocations in the rhetoric of product or through capitalism gives potential audiences license to ignore it as art.

Tools operate slightly differently. To be sure, there are lots of examples of connotations that could just as easily subvert intentionality. Of course, one of them is that tools are products. Companies like Black and Decker and Craftsman both seek to position themselves as the best for the job, and the marketing images around things like Father’s Day, pickup trucks, and NFL broadcasting emphasize how masculinity can be packaged and sold.

Tools themselves, though, are interesting in that they are fundamentally for getting things done. Despite marketing, there are good tools and bad tools, and ultimately, that’s what matters. To determine a bad tool is to try it, to use it, and to see how effective it is. Unlike electronic products, which can be dismissed from the everyday as ‘gadgets’ or made irrelevant by calling them ‘art,’ tools are defined by purpose, and evaluated through use.
