We Won the Open Science Design Contest

We won!
We won!

Great news, The Citizen Science Quartely just picked the winner for the Open Science Design Contest, and:
WE WON!!!!!!!!1111!!111one

You can read more about the original entry HERE.

We’ll be using the Ponoko gift certificate to design a housing for the electronics and make it more kit-able. Bench Science FTW!

And definitely check out the Kickstarter for The Citizen Science Quarterly. It’s shaping up to be a really interesting mix of Bench Science in the DIY spirit. From the Kickstarter page:

“We’d like to create a magazine for the scientist in all of us.

It will have simple How-To’s, like extracting the DNA of a strawberry using kitchen materials. But on the next page could have a paper on the validity of using Bacillus Subtillus as a model organism. We’d feature extraordinary citizen scientists who are doing extraordinary things in abnormal labs (aka garages, closets, etc). We’d also give legal and safety tips to inform and protect citizen scientists from some of the dangers they could run into.”

Making things Blink and Buzz!

Ever wanted to learn more about electronics but weren’t interested in taking a long, drawn out class on theory? Are you looking for a class that will pique your interest and spark your creative flow?

Then join us at Hive76 for “Making things Blink and Buzz” on January 29th. Join us for a day filled with blinking, buzzing and all out DIY geektopia. The class is open to anyone who is curious about electronics of all skill levels. The only requirement is a willingness to learn and a desire to have a lot of fun while doing it. Example projects will include a 555 timer and an Atari Punk Console (if you don’t know what these are then you definitely should come and find out). These projects are hands on, beginner friendly, and cool kit to take home and keep playing with, so grab a seat in the class before it sells out.

If you’re still unsure, Hive76 will be offering a free preview of this class during one of the weekly open houses in January. Far will be demonstrating how to build a “blinky bug.” Come meet the Hive76 crew, and find out how much fun DIY electronics can be!

Class: Making Things Blink and Buzz
Date: Saturday, January 29, 2010 from 10AM – 4PM (with an hour break for snacks)
Cost: $40 (Includes 4+ hours of class, as well as parts and materials).

We have only 15 seats, so get your Tickets soon.

Open House and Studios recap

The building we rent space from, 915 Studios, hosted Open Studios this past weekend. While most of us don’t make art, we did want to show off our cool projects to any visitors. I set up my DIY time lapse intervalometer and took pictures every 9 seconds all Saturday. Here is the completed video.

We also installed a new extruder in 3DPO, the Plastruder MK5. A lot of cool stuff was printed. Here’s a video of some successful printing:

Fynflood also got his Mendel up and running again. And printed a Hackaday skull:

How I Became a Maker

Probably the single most important decision about me that my parents made was to remove me from the institutional education systems and home school me. There was talk from my teachers of getting me diagnosed with Attention Deficit Disorder, but really I was just bored with my classes and had no socially acceptable concept of how to deal with that boredom (incidentally, I still don’t, but that’s a story for another day). Unfortunately for  Mom and Dad, they quickly learned that my disruptive, destructive tendencies would be visited upon them if they did not find ways to entertain me.

Enter: TOPS Science.

TOPS is brilliant. It’s a combination of comic book and pragmatic science lab. Everything in a TOPS science workbook can be done with house hold items. The topics cover a wide range: electricity, chemistry, biology, geology, meteorology–I wouldn’t be surprised if they eventually came out with a nuclear physics issue. I couldn’t get enough of them.

The materials were always simple, and something you probably had lying around anyway. For example, the electric circuits module used aluminum foil backed with scotch tape for wires, paper clips to connect them, and clothesline clips and rubber bands to make a flashlight bulb holder. There were never any exotic parts or chemicals in a TOPS module, and if something was slightly out of the ordinary, it would show you a convenient source for scavenging it from some thing else.

Even after all of the worksheets were done, I would still continue to play with the left over pieces, hooking up DC motors vultured from broken toys, making LEGO gears, testing out rubber-band belt drives, building switches made from bent-up paper clips and aluminum foil, and winding solenoids from ballpoint pens and wire from who-knows-where.

Some things that resulted from a combination of my boredom, ingenuity, and youthful ignorance:

  • A small catapult with a surprisingly long range and a poorly thought-out target area (i.e., a plate glass window).
  • A coil gun that scared the family dog into knocking over a ceramic vase.
  • Experiments in electrolyzing water for basic hydrogen and oxygen that resulted in several toxic chemicals as well as one small explosion.
  • Experiments in electroplating objects with metal from nails and paper clips that looked suspiciously a lot like the previous entry with largely the same results.

It was that second, small explosion that prompted my parents to buy me a computer as a compromise to prevent me from continuing with my increasingly dangerous pursuits in the physical sciences. But, I still carry the basic principles of analog circuits because of these awesome, little books. I don’t know what I ever did to deserve them because it would often lead to new ways for me to endanger my life/the carpet, but they are perhaps the most significant part of how I came to be a builder and maker of things.

Our entire building at 915 Spring Garden is taking part in Open Art Studios this weekend, and we’ll be there too!

Almost 30 studios will be open to the public, including Hive76! There’s a ton of different medias people use, everything from textiles to clays to electronics.

Come join us on Saturday and Sunday, December 4th and 5th, from noon – 5 pm at Hive76. We’ll also be upgrading our MakerBot with a new MK5 Extruder so we’ll be printing in tip-top shape again soon!

Open House, December 1st, 2010

We enter the cold, dark days of December with a super Open House meeting. As always, the night starts off with our 7pm Scrum stand-up meeting for members to update everyone on the progress of their projects. 8pm starts the official Open House, with pizza, soda, and snacks.

Keeping in our new tradition of “mini projects for open houses”, Adam and Jack will be showing everyone the basics of building electric motors. Previous open houses covered Glowsticks and Bristle Bots. Building simple motors is really a lot easier than you might initially think. Hand-made electric motors are a fun way to learn basic principles of circuits as well as a handy skill for any project that needs a little movement. Come on down and play with electromagnetic fields with us!

Toys that made me a maker

Pipeworks wrench
Pipeworks wrench

I visited my parents at home this Thanksgiving in Hillsborough, NJ and rummaged around the house I grew up in. One of the things I found was a Pipeworks wrench from my childhood tinkering. Pipeworks was a wonderful system that used basic PVC pipes with special connectors to make 90º and 45º angles and seat to snap in. They were like LEGO furniture. I created a wheelbarrow and lemonade stand as in the instructions, but of course quickly moved on to my own designs. The last and best being a small cart I dragged around on my bike until it fell apart. Here’s a video of kid actors having fun with the set. Good times.

Of course, the Pipeworks were only one in a string of awesome toys that encouraged making. As any kid, I had LEGO (that is the proper collective noun apparently.) A true LEGO collection is measured in mass, and I still have about 40lbs of LEGO in my parent’s attic; the ABS plastic withstanding the seasonal temperature shift, but the forgotten batteries corroding the contacts of the battery box in my super-awesome death robot on wheels.

Construx helicopter

But every kid had LEGO. I also fondly remember the more obscure Construx. This set was like a smaller Pipeworks with beams that could be connected to make stuff. I had a set like the one pictured here with pulleys and wheels, and I kind of remember breaking those beams quite often with the wrong amount of torsion. It was very architectural though.

I had some K’nex too, another beam toy, but a bit more flexible and durable than Construx. K’nex came out in 1993, and by the time I got some, it was a bit too late for my tinkering age. I was sliding into the deep abyss of adolescence and the darkness of CompuServe image boards.

As a kindergartner I would also play with the lacquered wood blocks at Grandma and Grandpa’s house. Grandma had a special set of blocks that she kept high on the mantle away from kids hands. They were heavy stone and rounded from years of play; she played with them when she was a kid. It’s amazing that while researching this post, I found those same blocks: Anchor Blocks, or Anker-Steinbaukasten as they are known as in Germany where they are still made. They are quite expensive now too. Is this the best present for my pieces and nephews? Maybe they can share a set.

Zaks

There was also a crazy toy called Zaks that I had a bag of. Zaks are equilateral triangles and squares that snap together at the edge. When completed, these polyhedral models look a bit like the STL mesh files I build today with the makerbot at Hive76. What made this set especially cool was that some pieces has a 4-stud LEGO pattern on them that allowed for easy attachement to LEGO models. I don’t know why I didn’t use this mind-blowing connection more in my models, but I remembered it just fine. Maybe I didn’t want to get my toys mixed up. I should have been building super intensive toys with Construx and the frame, Zaks, the moveable skin over a upper skeleton of K’nex with all the inner workings and details handled by LEGO attached to the top of a Pipeworks cart. Sigh. These are the regrets of a youth misspent. Today you can print out a Duplo block to Brio track adapter which to me seems like the greatest thing in the world. I wonder if I can print a Zaks-Construx adapter, or a new line of Pipeworks connectors with LEGO studs …

I got to get to work making stuff!

Tiny Terminal Using MSP430 and HD44780 Display

We have dozens of these HD44780-based LCD displays — now we just gotta make some use of them.  Here’s an experiment using an MSP430 to create a display that can be written to using serial data.  The displays actually have chips in them that can send the data as a differential signal (a la RS422), so it should be possible to send the serial over great distances if needed. The displays are also waterproof and have a six key membrane keyboard built in.  With the addition of a $1 MSP430, the setup turns out to be a pretty sweet building block …

A preliminary version of the HD44780 library for MSP430s is available here.
