I’m submitting an application for the Santa Cruz Mini Maker Faire 2017 (2017 April 29), since last year’s Mini-Maker Faire went well (see Santa Cruz Mini Maker Faire went well). This year I’m getting my application in early, rather than dithering about it for months as I did last year. I have less free time to prepare the display this year, but I have a better notion what I want to do, so it should not take long to get ready.
The “non-public” description of my display is straightforward:
I’ll bring a tabletop full of electronics projects, as last year (see https://gasstationwithoutpumps.wordpress.com/2016/04/16/santa-cruz-mini-maker-faire-went-well/ ).
Laptops demonstrating free software to turn cheap microprocessor boards into data-acquisition systems suitable for home labs and science-fair projects.
Homemade LED desk lamp and stroboscope.
Several of the projects will be interactive (an optical pulse-rate monitor, oscillators that can be adjusted to change Lissajous figures on an oscilloscope, …).
A few changes from last year: a more reliable pulse-monitor design and a new USB oscilloscope.
The public blurb is similar to last year’s:
See your pulse on a home-made optical pulse monitor!
Record air pressure waveforms using free PteroDAQ data acquisition software!
Play with a bright custom-design LED stroboscope!
Control fancy Lissajous patterns on an oscilloscope!
I removed mention of an EKG, because I decided that it was too much trouble to tether myself with EKG leads all day.
My “Maker bio” is a bit boring, :
Kevin Karplus has been an engineering faculty member at UCSC since 1986, but has done hobbyist electronics on-and-off since the 1960s. For the past few years he has been working on a low-cost textbook to make hands-on analog electronics accessible to a wider range of students. Several of the projects on display are from the textbook.
