Nick sent out to our mailing list info about the closet desk for his home that he built up at the space, here’s what he had to say and some pictures of the project:

… I was up there into the wee hours of the night Saturday working on the ‘closet desk’ project I recently started.

Dan's Rep rap Prusa 3d Printer

I get a lot of blank stares and strange looks when I tell people that I am working on a 3D printer. As such I’d like to set out to explain what one is as well as show off what I’ve completed on mine thus far.

So you ask, “What exactly is one of them there 3-Dee printer things you’re talking about?” In short, it is a rapid prototyping machine. Since I’m sure that clears it all up and removes any further questions you have in your mind, I’m done here and everyone’s good to move on to the next blog right? No of course not. The best explanation I have is it’s a machine that takes a plastic material, melts it down, and places a thin layer of the melted plastic one layer at a time until you have a finished object. It is a printer that works like your old school inkjet printer but also moves on a 3rd axis to make non flat prints.

Claudio's RepRap Prusa

The idea is as follows. What do you do when you want to develop some brand new, earth shattering, world stopping, sign of the apocalypse product that has never been in existence before and it needs a custom part that even Nostradamus didn’t predict? You design it of course, in your favorite 3D modeling software like Google Sketchup or Blender or any of the other dozens that are out there. The show stopper before was how you went from a digital model to something tangible that you could hold in your hands and break if you are one of those accident prone individuals. It always meant that you had to go pay some exorbitant amount for a machine shop to make you just one of that item, and heaven forbid that item didn’t fit the needs on the first round. I’m sure you can imagine where the price would go up rather quickly in development. So why not just make it out of cheaper material and something that works just well enough to serve as a proof of concept. Well, that’s exactly what the 3D printer does for you.

A handful of months ago two of the other members at our hackerspace and myself all decided we wanted to build our own Prusa 3D printers. No real defined reason behind it other than we knew we wanted our own printers, and that if we had one it would open new possibilities to us. Since there is no real completion point for these things, it would simply be that once we had it “working” we could use it to create new items and repair or replace old ones that were no longer available. That in a nutshell is the appeal of having such a device and the driving force behind our continued development of them. One of the single most awesome things about this particular printer that we are building, the Prusa. Is that it’s relatively cheap, easily reproducible, modular, and upgradeable. Currently we are in the process of getting them fine tuned and working to some extent. From there we’ll be able to spend further time using it to upgrade itself and improve it’s quality. Expect to see more details in the near future right here on my very own blog enlightening all of the saga of blood, sweat, tears, cursing, and agony that is the way of life a homemade 3D prototyping machine is.

This Friday February 18th at Republic Coffee we’ll have members showing off their Arduino projects and answering questions about the Arduino platform. We’ve had a lot of interest in getting started with various Arduino boards so come learn more about the great things you can do with an open source platform.

What is an Arduino? Arduino is a physical computing platform and a software development environment for controlling various things like motors, sensors and even entire devices. The hardware and development environment are open source and there is a very large community of developers and hardware hackers out there working on projects. The hardware is also quite inexpensive. There are also “Getting Started” kits that are a package of items to help you hit the ground running with your Arduino.

This Friday Feb 11th 7pm @ the space come check out what we’ve been working on with 3d printers. We’ll have 3 Mendel printers in various stages of assembly. Come by and ask questions, hang out, and see the progress. Dan and Claudio will be working on early stages of assembly and Sonny will be working on later stages of assembly of his Mendel. Nick’s Makerbot will also be at the space to show off differences between it and the Mendels.

If 3d Printers aren’t your thing then feel free to ask for a tour around the space. Our Friday meetings are open to the public. Come by and see what we’re all about and of course, feel free to sign up for a membership!

A couple of weeks ago I was looking at making my own wedding favors.  I stumbled onto two thing. 1: homemade soaps, 2: homemade bath salts.

I found some information from a few places and found that for soap making, there are 4 methods: Melt and pour-the easiest (but it’s compared to baking a cake using boxed ingredients versus cooking from scratch); cold process- mixing up your items from scratch, the lye, oils, ect; hot process- a similar variation of cold process; and rebatching- grinding up premade soap bars and adding in your own extra ingredients.   For the beginning of a new project I’d like to start with something a bit simpler, so I went with the melt and pour bases.   I found an inexpensive source for soap making supplies that had beginner kits (kits with small quantities of multiple items).  Within a week I received the supplies. I got a few different types of soap.  I got a few different oils for scent, and a few other items I thought might be a good idea.  I’ve always loved strawberry scented things, so I got some strawberry oil, seeds, and some pink soap dye to play with.

So on the next Friday, I was off work, thanks to pulling a 22 hour shift the night before. I started with making the strawberry soap.

First: I cut up a pound of Shea butter soap.  (A pound is a bit less than I thought it would be.  The mold I purchased holds exactly 2 pounds of soap and makes 8 total bars.  For my first batch I improvised with a Ziploc container lined with wax paper)

Second: I heated up my solid aluminum double boiler to melt the soap.  After the soap melted, I put a few drops of the strawberry oil in, I played with the amount until the smell was just right.  Then I used the soap dye and added it until the soap was a desirable color.  I also used strawberry seeds to add exfoliants to the soap.  Lesson learned: strawberry seeds float; they all ended up on what was to be the bottom of my soap.

Next I decided to make some lemony soap.  I used the goats milk soap and the honey soap.  Honey soap is a clear base, and goats milk is a solid base.  I melted the honey soap and used one scent on it – listea cubea. After the first layer had formed a shell on top, I melted down the milk soap and mixed a little yellow food color and verbena scent.  I am much more pleased with this attempt.

When looking online for small gifts I can use as favors at the wedding I found homemade bath salts…  To make them it’s surprisingly easy.  Pour in the salt of your choice- Epsom salt is the suggested.  Then you mix in your color- just 2-3 drops of food coloring.  Then mix in 2 tablespoons baking soda and the scent of your choice.  that’s it.  Simple.

I also accidentally found a body scrub that is only slightly more complicated.  It takes a whole 15 minutes to make a batch.  3 table spoons of: white sugar, turbinado sugar, 1 table spoon of glycerin, baking soda, and salt of your choice.  Then you add olive or almond oil to it until it’s about the consistency of a slushy. Last you add your scent, about 1-2 ml works perfect.  That’s it, and it works great!
