Like playing chase-the-laser-pointer with a kitten.

After a couple weeks of hacking on the Gilson we have PID* control.

When we first saw the Gilson, we didn’t have access to any feedback mechanisms. All we had were panic stop modes of control. After a ton of experimentation, and Nick reading five control theory books, we are having fewer incidents in which someone yells “Holy Crap Make It Stop Before It Destroys Itself!” It’s not yet a null set, but the cardinality is significantly reduced.

When life gives you busted up old LCD panels, make… lightboxes! I constructed this one out of the CCFL backlight from an old laptop LCD I found around the space. It gives a nice, even white light, and runs off a 9V at about half an amp.

The inverter for the backlight was long gone, so I replaced it with one of these inexpensive CCFL inverters from MPJA.

A little hot glue and acrylic cement later, we have a perfectly serviceable lightbox. Now, what ever could we use one of those for?

At a recent meeting I had a chance to sit down and check out Bill’s “Simple serial display” which, true to it’s name, is simple, but that doesn’t stop me from wanting one badly! Watch the vid to see it in action, and check out Bill’s earlier post for more info!

New in the NYCR vending machines are Teensy 2.0 boards. They have ATMega32U4 chips, which have the built in USB drivers and, via LUFA, can appear as any USB device, not just a serial communications device. Want to make a MIDI device show up as a USB keyboard? Or a core memory as a mass storage device? You can do that! The USB doesn’t consume a UART, so there is still a serial port available for interfacing with GPS or other external RS232 devices.

PJRC makes the Teensyduino plugin for the Arduino IDE and a set of compatible libraries so that you can use it with your Arduino sketches. Or you can drop into straight C and take full advantage of all of the AVR pins.

Update: They are very popular! Three were bought during Craftnight tonight.

As the saying goes:

Dear Congress, It’s No Longer OK To Not Know How The Internet Works

Jan. 24th will be a big vote for the Internet. PIPA, SOPA’s twin will be voted on in the Senate. Here’s what we’re doing to let our Senators know they should reject PIPA on Jan. 24th. We are asking our 2 NY State Senators to have town hall meetings or an in-district meeting with us (you can request them but sometimes the request stuff like faxes). We don’t have a date for a meeting in NYC yet, because the Senators are on recess and it’s difficult to effectively schedule a date with an answering machine. New Yorkers, stay tuned, we’ll announce the date to meet with our Senators. If you’re not in New York – we urge you to contact your Senators for a town hall meeting or in-district meeting in your area before the Jan. 24th vote. Those of us who call the Internet home need to educate Congress on the dangerous nature of this Act, because srsly, do they get how DNS works? Or what xkcd is? We don’t think so.

The following is a citizen packet prepared by Public Knowledge: 

Tell Congress to Reject Internet Censorship Tools in PIPA

On January 24th the United States Senate will be voting on S. 968 the PROTECT IP Act (PIPA). Your two Senators will have the opportunity to decide whether America will adopt the tools of censorship used to block websites in China or reject them by voting no and standing with Senators Wyden, Moran, Paul, and Cantwell. Ask your two Senators to stand against adopting the tools of censorship in any bill that comes up for a vote.

What you should know about PIPA:

• 83 of Internet’s original creators including Vint Cerf, co-designer of TCP/IP, and Robert W. Taylor, founder of ARPAnet, oppose SOPA and PIPA.
• The government has a poor track record of protecting free speech on the Internet. For example, lawful hip-hop music blog Dajaz1.com was held by the government for anentire year on the accusation of copyright infringement.

• Think tanks, government agencies, and industry associations across the political and social spectrum have said that SOPA and PIPA would undermine freedom of expression
• Top cyber security experts have said that SOPA and PIPA would undermine a 15 year government initiative (DNSSEC) to update Internet security.

• Human rights groups have told Congress that PIPA would help censorship regimes like China and Iran by sacrificing America’s fight for Internet freedom worldwide.

• Congress has yet to allow experts on free speech, network engineering, Internet security, or human rights testify at a hearing on PIPA.

• The content industry has spent $94 million in lobbying Congress to pass their bills in 2011, arguing that if China can censor the Internet the U.S. can also do it.

• Lobbyists have misled Congress by saying the United States already uses censorship tools for malware and child pornography.

Sample Town Hall Questions:

•  Will you stand with Senators Wyden, Moran, Paul and Cantwell and oppose Internet censorship on January 24th?
•  Do you understand what the Domain Name Server (DNS) system is and have you consulted with cybersecurity experts on the effects of the Protect IP Act?
•  Would you still vote for Protect IP if it restricts freedom of speech?
• Have you taken money from the movie and music industry?
