What: a workshop exploring the gender gap in tech, science and math
When: 2 p.m. on Saturday, September 22, 2012
Where: HacDC (location info)
In 2005, 22% of computer science graduates were women. This is down from 37% in 1985. Have you ever wondered why more women aren’t working in fields of math, science and technology (or going to hackerspaces?) Join The Hacktory to learn more about the research on this problem and hear from others about personal experiences. We have a hands-on activity that will show how this problem persists, and identifies practical solutions each of us can use to combat it.
This event is free and open to participants of all identities, gender- and otherwise. To help us know how many participants to expect, we ask you to RSVP at the meetup event page.
Tonight: Diodes and Ring Modulators.
I’ve gotten in a bunch of XOR chips, and that lets us do ring modulation — the key to getting that tuning-in-the-shortwave-radio sound. (And more!) It’s lots of cheap, easy fun.
Once we get a handle on the XOR, we’ll make variable-width pulses. This gets us a cheap phasing sound and will let us sync a bunch of oscillators to each other.
But do we dare combine multiple sync’ed oscillators with XORing?!?! Oh yes.
Bring in breadboards (preferably with your 74HC14 and other chips). We’ll be making a bunch of quick and dirty circuits and there’s too much room for experimentation to be soldering this stuff up. As usual, I’ll have parts if you need them, but today you can also re-use any of the stuff you haven’t soldered down.
An 8-step bleepy-bloopy sequencer? On a shoestring budget? Impossible! (Or is it?)
This project is a fair step up in complexity, so we’ll assemble and test on breadboards first. I’ll try to pick some up at Radio Shark, but please bring your own if you’ve got ‘em. Also, feel free to bring in your old noisemakers; we can splice the sequencer circuit right in.
And if you’re just coming to a workshop for the first time, this is paradoxically a good time to jump in. You’ll be behind on some of the “theory” but we’ll catch you up quick.
See you all at our regular time — 7:30 at the HacDC space!
For the next few Thursdays at 7:30 pm, Elliot will be leading a workshop on sound hacking from the ground up. We’ll mostly focus on building our own gear, but we’ll also borrow a couple tricks from the glitch/bender tradition.
April 16th, we’ll start off by scratch-building a mess of raw sound sources. After that, we’ll work on smoothing out the rough edges and trying to make this stuff more musical. (Or you could go for more cacophonous. It’s up to you.) After the first two or three weeks, I’m open to suggestions. Let’s see where we can take
This workshop series is going to involve soldering, (ab)use of digital CMOS chips for analog ends, a smidgen of electronics knowledge provided), and enough noise to ensure that you leave with a good solid headache.
Bring $5.00 to cover the cost of materials for April 16th.
Bring around 3-6 volts’ worth of batteries if you’d like to leave the space with something powered up. Two to four AA, AAA, C, or D cells will do. Three if you’re using rechargeables.
Also, if you’ve got a breadboard and would like to use it, bring that too. Otherwise, you’re going to be doing it dead-bug style like me.
Come on, feel the noise!
