Create your own Lock Picks!

October 15th, 2011 5 comments

The Lock Forensic group at Hive13 is having a class  to show you how to create your own high quality metal bogota style pick set.  The study of locks and lock picking is fascinating.  A bogota style lockpick has a backend that can also work like a tension wrench.  We will be making 2 of these style picks in the class.  The two stiles will be the half diamond and the hook.  If time permits we will have templates to make some more advanced designs (such as the actual bogota).  We will also have lots of test and progressive locks to test our your new lock picks on as well as a quick demo on how to picks locks if you haven’t yet.

Proceeds from the class will goto buying equipment for the lock forensics lab.  Lock forensics is the science of analyzing a lock to determine if it has been picked, what tools were used and the skill of the attacker.  Hive13 holds the only known public group doing this research and welcome anybody to participate on the 2nd Thursday of every month.

Example of the type of picks you will be creating:

LED table placecards

October 15th, 2011 2 comments

Inspired by this Instructables post, a friend of mine decided to create something similar for his wedding.

The bases were a bit more advanced than the suggestion, and all were created by a friend of the groom. They consist of a block of wood, a battery holder and 3 red LEDs.

The plates were etched & cut on our laser over a period of about 15 hours. It was about one hour per plate, 12 of which we used, 3 were used to perfect the process. This video shows a time lapse of the process.  We had some trouble initially with clouding on the plate, especially around the letter “o”.  We fixed this by adjusting the power and speed of the laser and refining our post etching cleaning process.

After the plates were etched and cut they were soaked in water & simple green for about 30 seconds, then wiped off with a microfiber cloth.

The cards were then set up at the reception hall prior to the wedding, and remained lit throughout the evening.

The wedding party:

We didn’t have the names of all of the dates guests were bringing, so some people got their very own +1.

And of course we had to create a bonus plate for the Hive:

The Bride & Groom were pleased with the results as were we.  While it was a lot of work, the project resulted in a unique keepsake for each wedding guest and the wedding party.

Glass Block LED Matrix, controlled outdoors via tablet

October 13th, 2011 5 comments

DSC_4648.jpg

Short version: Using an Android tablet, you can draw things on our Glass Block LED Matrix from the street, and it’s pretty awesome. Video here, photos here.

Long version:

Things have progressed recently on the Glass Block LED Matrix which Chris Davis and Paul Vincent started. For a couple weeks, the code was already in place to let Processing talk to it via simple serial commands to the Arduino & ShiftBrite shield. We wanted to use the tools from Project Blinkenlights to control things over the network; while this didn’t entirely work as planned, the project offered a lot of ideas and inspiration.

The most recent addition I made was the inclusion of oscP5 to the Processing sketch to let it listen for OSC (Open Sound Control) messages. As it happens, a brilliant piece of free software already exists (Control from Charlie Roberts) which turns Android/iOS devices into control surfaces that send out OSC messages. On top of this, Control comes with a handful of example UIs, one of them being “Multibutton Demo” which provides a UI with an 8×8 button grid, sort of like a monome. (The tablet in all of the photos is running Control with that Multibutton Demo UI.)

As our LED matrix is 7×8, this UI was a good initial match. I set Control’s destination URL/port to the backend machine that was running Processing, set the sketch to parse the pretty simple OSC messages Control would send out at every button toggle, and then I was able to control what was on the LED matrix by drawing on that 8×8 grid on my tablet.

I finally got to show it off outside on Tuesday evening when it was dark, and it’s working pretty well, as the video shows.

Next steps:

  • Making a Control UI that allows for color control. These are RGB LEDs, after all – we can control intensity and color, not just whether they’re on or off.
  • Making this web-enabled. I think Control allows this?
  • Fixing the glitchiness that I didn’t show in the video; something cryptic is going on on the Arduino side.

UPDATE: nerdydad will be giving a presentation and demo on upgrading the rom+memory+IOS on a Cisco 2600 router. i’ll do the dual boot talk if time permits.

Cinci2600 is this Friday, October 7th at 7pm. I’ll be giving an improved version of my hipster linux dual booting talk from last week’s NKYLUG. If you have something that you would like to present, or if you have something cool to demonstrate please feel free to bring it and show it off. Also feel free to take advantage of the hive being open to hang out and work on stuff.

Weekly meetup for “Intro to AI”

October 5th, 2011 No comments

The free online version of the “Introduction to Artificial Intelligence” course (http://www.ai-class.com/) based on Stanford CS221 starts next week. As several members signed up for this course, we are going to be meeting up at the Hive on a weekly basis to watch the lectures and work through some of the homework. We’ll meet first on Wednesday, October 12th, at 6:30 PM, and the intention is to keep meeting each Wednesday at the same time for the 10 weeks that the course lasts (course schedule is here – it runs through the week of December 12th).

Lectures are supposed to appear online each week, and I’m told they’ll also be downloadable. I will try to download the videos ahead of time and have copies of them locally. Other than that, we’re just going to play things by ear – I’ve never done a course like this before, perhaps because no course I’m aware of has been done like this before. Something you can program on (i.e. a computer)  might be helpful to have. Quoth their website, “Programming is not required, however we believe it will be very helpful for some of the homework assignments. You may write code in any language you would like to (we recommend Python if you are new to programming) and your code will not be graded.” A textbook is not required but is supposedly helpful, and I think some people said they had older editions they could bring in.

If you’re taking the course, or you want to take it, please join us. You don’t need to be a Hive13 member. You don’t even need to be enrolled in the online course, for that matter – but it’s free and enrollment is open until October 9th, so you may as well.

Eagle PCB CAD Crash Course

October 2nd, 2011 No comments

 

If you’ve wanted to make your own circuit boards and turning the schematic you have on paper or in your head into a finished board is the stumbling block, this course is for you. This Eagle PCB CAD Crash course is intended for those who already know what an electrical schematic is and vaguely how to construct one – the focus will be exclusively on Eagle software NOT general electronics knowledge. The course will be an introduction to the Eagle software available from http://www.cadsoftusa.com You should have Eagle installed on a laptop prior to coming to class – both the Linux and Windows versions are fine. Creating schematics, creating boards from schematics, basic manual layout chores, the relationship between schematic and board, making gerber files for board houses, finding libraries, making custom parts will be covered. If you have a schematic that you would like made into a PCB, please bring it with you as a “real” example will be much more useful than a contrived one. If there is time, creation of solderpaste masks using the laser cutter will be covered. I’m going to try to leave around a third of the class time for questions and individual assistance.

Date 10/12/11
Time 7pm
Length ~2 hours
money $20 / $10 hive members (See discount code in email)
Max people: 15
