Freeside Atlanta

In the last meeting of the Entrepreneur discussion group, we talked about business plans for our different ideas. Most businesses (Profit/Non-Profit, Product/Service...) that require some level of investment, fit into a similar planning pattern. We looked over one planning tool that I developed in Excel as an example of that pattern, which is then reflected in the example business plan that I posted to out Dropbox share (email me if you'd like access). The model works by developing the product and estimating it's price and market potential ( revenue projections ). Next, you develop the cost model ( bill of materials, equipment, facility, labor, administrative ). These costs are allocated by product (or service) and together, the revenue and cost projections form the key financial data ( Annual Operating Expenses, Pro-Forma Income Statements, Cash Flow Analysis, Breakeven Analysis By Product, Working Capital Requirements ). All of these are based on research and best-gues

Join us a Freeside next Thursday for an Introduction to Arduino Class. The class will be aimed at the basics of Arduino Programming, so some programming experience in any environment would be preferred, but is by no means necessarry. We will even have a limited number of Arduinos and Computers, however if you have the ability, please bring your own laptop and Arduino to work with. Location: Freeside Atlanta Time: 7:30 - 10:00 pm E-Mail: freesideatlanta@googlegroups.com

Just finished the Saturday series of welding classes at My Inventor Club. Matt from Freeside taught this one, but Shane from MIC does a series too. Here's Newt on the MIG while Charlie and I are playing around with aluminum on the TIG. Gloves and trendy jacket belong to the house, I just had to bring the glasses. Ear plugs may be a good idea too. Here I am, grinding down a piece for an ugly, abstract sculpture to practice on. All in all, we learned and then got to play with Oxy-Acetelene welding and cutting, grinding, portable band saws, MIG, Stick, TIG, and cut-off wheels. I came in with no experience and left with at least enough knowledge to not burn my own eyes out. According to Matt, they do the classes as 3 weeklies on Wednesdays, Thursdays, or Saturdays with 2-4 person groups. Drop a line on the Freeside mailing list if you're interested and they'll put together a class.

Sort of late to the show but here we go: Sign up today! http://wiki.freesideatlanta.org/classes/arduino

Next buildout is scheduled for March 3, 10:00 AM - 6:00 PM. For those not in the know, Buildout is when Freeside's members get for the purpose of making the space better, socializing, and eating food. Incidentally non-freesiders are more than welcome to show up, help, socialize, and then *maybe* become members afterward. Buildout's a great time for anyone to show they care for the space. If you have an idea for what needs worked on, please add it to the task list here: https://sites.google.com/site/freesideatl/build-out/to-do If you need something for said task, such as a ladder, please feel free to add it to the list here, and we'll try our best to see it shows up. https://sites.google.com/site/freesideatl/build-out/shopping-list Incidentally you might notice that many of these items don't have a responsible person. If you can please try to take ownership of at least one task. If you don't know what the task involves, it's possible no on else does either. Take

Stanford University will be offering free online classes this semester in a variety of fields. Students will receive a certificate of completion at the end of the class too. We at Freeside are forming a study/discussion group to help people through these classes and kick around ideas related to the subject matter, with a focus on the Technology Entrepreneurship classes. any of the classes are open for discussion, so feel free to grab what interests you. The group will meet on Saturdays at 6pm. Classes still haven't opened yet, so it's not too late to sign up for one. You can find the main class here - http://www.venture-class.org/ and the links to the other classes are at the bottom. The following classes will be offered this semester: Entrepreneurship      Lean Launchpad      Technology Entrepreneurship Medicine      Anatomy Civil Engineering      Making Green Buildings Electrical Engr.      Information Theory Complex Systems      Model Thinking Computer Science      CS 101  

I've been running Sprinter on a RAMPS 1.4 control board for my MendelMax since I built it a few weeks ago. This is the most common firmware in use, with the most community support. However there are other firmware options that are faster and more cutting edge, at the expense of having more bugs and a smaller user base. Today I switched to Marlin because I read that it handles acceleration between moves more smoothly, and can draw smooth arcs as well (a much more experimental feature). I chose this funnel as my test print because the cone and cylinders comprising it cover a range of arc sizes. On the left we have a print with Sprinter. There is a strong ridge at the layer change point near the left side, and additional ridges on every edge around the model. This print took about 40 minutes. In the middle is the exact same gcode run by Marlin. The edge ridges are gone, but the layer change ridge is more pronounced, especially on the cylinder at the top. This is much closer to wh

Zane, a member of the 7Hills Makerspace (http://www.7hillsmake.org/) to the north of us, has made this great light display for in front of his house. "...powered by a bluetooth enabled Arduino..." About $30 in parts and many hours with Zane's brain. http://zanecochran.com/entry.php?blog_id=335 Check out their group at http://www.7hillsmake.org/ and tell them Freeside says "Hello."

Our Dr. Glass and Sparr fight it out on who can create the fastest. From Dr. Glass: This was part of a "Day Project" at FreesideAtlanta.org In all fairness, Sparr and I became challenged in a Speed-Modeling contest. Me on Lightwave 3D and he on OpenSCAD. Sparr was victorious, but agreed to let me upload my model anyways. Thanks bud. I'm including this original as well as the Freeside Atlanta emboss.

Now that winter is coming to the northern hemisphere, getting up for work means getting out of bed before the sun comes up. In order to help the natural waking mechanism of light, I've decided to hack together a sunrise alarm clock on a shoestring budget. Part List: Arduino Real Time Clock Module ( http://www.sparkfun.com/products/99 ) 24xAssorted LEDs (In my case: 3UV, 2 Blue, 4 Red, 3 Yellow, 12 White) 24xResistors, 220ohm Solderless Breadboard Assorted wires 3x74HC595 shift registers A Shadow Display Box Frosting Spray To put this thing together I used Elco's ShiftPWM Library to control the 24 LEDs. You could go bigger, but I wanted this to all fit into the box. Personally, I had some PCBs from a previous project that I could fashion to make the LEDs easier to mount. Everything is hooked up like in the schematic: The "To SCL" and "To SDA" lines go to the Real Time Clock Module. The parts are all mounted to the backing board of the shadow display box lik
