Make Things Awesome(ly Scented)

I’ve been wanting to teach a class on how to make DIY/handmade personal care products for a while (a long while) now. Now, finally, it is happening! On Sunday, December 2nd, from 12-2:30pm, come learn how to craft your own personal care/beauty products from all natural ingredients! Together we will create a variety of body care products– such as aluminum-free deodorant, fabric softener, lip balms, and hand salves– using simple, inexpensive recipes composed of non-toxic materials like cornstarch, olive and coconut oils, beeswax, dried herbs, honey, and essential oils. We will also learn how benign, common household ingredients like baking soda, vinegar, salt, lemon, and hydrogen peroxide can be used to effectively clean around the home. Everyone will leave the class with their own handmade samples of lip balm, deodorant, fabric softener/scented sachet, and hand salve. Sounds like fun, doesn’t it?  I’m super excited to share the processes, recipes, and resources I’ve come across/developed/tweaked over the past couple of years of making my own personal care and cleaning products. Not only is it a fun way to spend an afternoon, but it feels empowering to have control and awareness of what goes on your body. I’ll be showing you just a few more ways that you can avoid consuming—and embrace making—in other aspects of your life!

Added bonus: these easy-to-make products can be re-created on your own to be used as gifts for the upcoming holiday season!!

Zombie Web Series Kickstarter Time!

ZOMG GUYZ!

One of my first projects here at Hive76 was the Burning Zombie Dummy. A friend of mine had called me, asking me if I knew how to set people on fire safely, and that led into a very stern discussion about what he was trying to do and that I would take over so that noone would get hurt. So I became the Special Effects Design Engineer for Exile: The Family You Choose, and it was one of the best times of my life. I got to do some pretty awesome things (including making an impromptu harness for doing a shotgun-to-the-chest effect), met a lot of really great people, and learned a lot about a hobby that would ignite my passion in a way I hadn’t felt in a long time. Seeing our end result, this thing that we made together, from start to finish, without any adults (of course, we’re all adults, but you never really feel like it) helped to further cement my belief that anyone is capable of doing anything. The hacker spirit is strong in the indie film world. Continue reading “Zombie Web Series Kickstarter Time!”

The No-Video Game!

It’s a vidya game but not! A completely audio-based game, the objective is to use sonar to find the hidden submarine and destroy it with depth charges. But be careful! If you are not close enough to hit the submarine, it will get away and you must hunt it down again.

Got an Arduino Mega2560 on the innards side. Got the joystick and arcade buttons from Ada Fruit! Very nice quality, shipped very quickly, and not too expensive to boot. Box was just a little, prefab wooden deal from a craft store somewhere in the middle of nowhere. And the speakers, I think I pried them out of a few alarm clocks.

Open Source is a Philosophy, Not a Checkbox

I just got back from the 2012 Open Science Summit which took place in Mountain View, CA. It was an excellent meeting and a great opportunity to meet others using open tools and ideas to forward Science! Check out the list of talks and you can also access videos of all of the talks. And you can also read more about the speakers.

I gave a talk too where I delved deeper into the science behind our work with RepRap for research in Regenerative Medicine and I made the case that open source is a philosophy, not a checkbox. Try not to get caught up in semantics of open vs. not-open (e.g. one could try to label Arduino as not an “open” platform since it has proprietary Atmel chips on the board). Instead, try to think of open projects as those in which you see people as collaborators (“open”), not customers (“closed”). We all have many things we can learn from each other, and who doesn’t want more collaborators to learn science together? Some interesting Q&A at the end too.

Hive76 gets interviewed by CNN

CNN stopped by the space last night, Oct 22nd to interview some of the guys on their projects for a report called “Made in America” which airs Tomorrow, Oct 24th. However, we did shoot some cool video and photos alongside them. There’s a full album available on our Facebook page.  We were also fortunate enough to get some quick shots of our projects at work.

Tonight at IndyHall: Cory Doctorow book reading and 3D printed sugar

We are cosponsoring Cory’s Pirate Cinema event at IndyHall tonight, but since there’s not much for Hive76 to do, we decided to make him a present. Here’s a video of production last night:

That’s a 3D printed sugar head! Cory’s excited to see it in person. You should be too! Come to IndyHall 22N 3rd at 7pm tonight. Here’s the Anyvite link to RSVP. We’ll be bringing a boomcase for the PA too.

The gritty details: That’s a Baricuda extruder using air pressure to extrude molten sugar. Now I need to figure out how he can get it home to the UK in one piece.

Fast JavaScript Game Loops

Change

Okay, so I’m going to switch over to a very simple format, with very short examples of how you do certain things. The long article format is just too much for everyone to digest and takes too much time for me to write, so I tend to put it off forever.

Types of Games

Most games fall into two patterns: turn-driven or time-driven.

Turn-driven games have distinct periods where user input is taken, then periods where game updates are made, and the two do not overlap in anyway. The user-input section waits for the user to make their choice, and the user then waits for the update section to finish before they take their next turn. Many puzzle games and most board games are going to be of this type. For example, in chess with an AI player, the game waits for the player to move a white piece. Once the player moves, the AI takes over and calculates a move for a black piece, during which time the player is stuck and cannot make any moves. Once the AI has moved the a black piece, it’s up to the player to make a move decision again, and the AI cannot progress until the user has decided.

Time-driven games work completely differently. They are constantly updating the game, never waiting for the user to first make a selection or hit a button or waggle their joystick. If a user does perform some kind of input, the input is not processed separately, it is taken into account for the next update. Think of a game of Asteroids, in which the big, giant rocks float around the screen all on their own until the user decides to turn her ship and blast them.

There is actually a third class of game called alternate-reality games (ARG) that do not really update and do not really take user input–not in the same way these other games do–but they are way outside of the scope of this project. ARGs are more literature projects than programming projects.

Turn-driven games are relatively simple to create, as the user drives everything and performance issues do not cause noticeable artifacts like frame-rate stutter or audio clipping and buzzing. When we get into handling user input, you’ll learn all you need to make turn-driven games. Actually, time-driven games turn out to have many of the same features as turn-driven games, just with the additional features of not waiting around for the user first, having its own pump to drive the game forward.

We will be focusing on time-driven games, as they are the most technically challenging.

Fight, Robots, Fight! Built at Hive

The original ALF 120lb combat robot, 2005.

Many folks surely remember the days of fighting robots on TV: Battlebots, Robot Wars, Robotica, etc. And while its televised days are behind it, the sport is kept alive by groups of builders and competitors across the country. The Northeast Robotics Club (NERC) is just such a group, and one that I have been a member of since I first saw robots destroy and get destroyed on TV.

In the years since, I’ve traveled up and down the East Coast competing with robots of my own. But this past weekend, our own city of Philadelphia hosted NERC’s annual Franklin Cup, held in conjunction with the Franklin Institute. For this event I decided to continue the lineage of a long-standing family of NERC bots: ALF!

Now, this is the first robot I’ve built since I’ve moved to Philadelphia. My center-city apartment is about the size of a large phone booth and lacking any machine tools, so it’s obviously not a good workspace. The Hive, on the other hand, with its storage space, large work areas, and 24hr availability of tools and resources, was the perfect place to build. It may sound like a shameless plug, but the story of ALF would be incomplete without it.

Hive76 @ Maker Faire NYC 2012

Hive76 sure made the rounds at this year’s Maker Faire. With 2 tables in the 3D Printing Village, we had a steady stream of visitors both

 

days, ranging from Chocolateers, Digital Artists, to young children asking about 3D printing toys and parts for their projects. Discussion started about 10 minutes after we left Maker Faire for what to do next year. Check out the album for some quick snapshots of this year’s events including Karaoke, Thumb Wrestling, and of course, the occasional interview.

We are running a 3D printer race at Makerfaire

At Makerfaire in NYC this Saturday, Hive76 will be running a race to test the quality and speed of any 3D printers that would like to participate.

We will have an announcement and official start in the 3D Printer village at noon on Saturday. But the basic premise is this:

  • We will announce and post a 3D model on this page.
  • Racers will download and print the model in any material
  • The model will need to fit on a metal part and hold water
  • The first part to hold water without leaking for 5 minutes wins!
  • The prizes: a Math Watch by eagleApex (me) and a file to print your own trophy!
In summary, printing an accurate, water–tight part quickly will be a good balance of those three 3D printing goals.

Besides this 3D printer vs Man race, I think this is the first race of it’s kind! I hope you participate and I’ll see you there.

Update:

Here’s the file for the race!
