At the last 2600 meeting they demonstrated "check washing", one of the easiest forms of check fraud to perform.  Though the technique may be decades old and well known, we discussed how the digital age makes it a much bigger threat than ever before and what you can do to protect yourself from it.

Sunday evening Arch Reactor held a presentation for the Introduction to Unmanned Aerial Vehicles (UAV), Systems (UAS), and Remotely Piloted Aircraft (RPA).  St. Louis University's Senior Research Assistant for the Center for Aviation Safety Research, Richard Steckel, cover topics including "the current state of the industry, the booming market for UAV pilot careers in the private sector, and how the FAA is reacting to this new tech.

Last night Arch Reactor hosted a 3D Printer Build Night as part of the St. Louis 3D Printer Meetup Group with at least 35 attendees.  The printer for the evening was a donated PrintrBot kit from one of Arch Reactor's members.  Since the total assembly time would end up being 12+ hours, Ryan and Scott pre-assembled some of the more minor assemblies to help speed up the process and get to the more interesting parts.  In addition to the kit building, there were several other printers running which varied from an UltiMaker, a couple different delta printers, and modified Lyman filament extruder.

  1. Silk Transfer Easter Egg Dying
    • Start time: 01:00pm
    • End time: 04:00pm
    • Arch Reactor crafting / upcycling workshop, Alix is going to teach us how to silk dye eggs. Free

      Facebook event page: https://www.facebook.com/events/1523577781238060/

      Did you know you can dye an egg with a silk scarf? Alix will show us her secret method. Bring your imagination and crafting supplies. Bring cool easter related projects you have done to show off.

      Bring a snack or wine to share. AR has a microwave, refrigerator, and sink (cold water only though).

      Crafting stuff to definitely bring:
      - blown eggs (See instructions below). If you cannot figure out how to do this, bring unblown, raw eggs and I will show you how. Use white eggs only, any size. Any white eggs will work but free range ones tend to have thicker shells and so are a bit easier to work with.
      - brightly patterned silk fabric. It must be 100% silk. Neckties work best, the uglier the better. I will bring extras of this so if you don't have any, that's OK.
      - egg carton or other egg container
      -small buttons. I will also have extra of these.
      -glue gun, if you have one.
      - scrap cotton fabric in a light color. An old white t-shirt works well.
      -wooden skewers and a piece of foam to make a drying rack. You can get a foam wreath base from the dollar store. Alternatively, one of those cardboard egg drying things from a commercial easter egg dying kit would probably also work well.

      This is kind of half show and tell and half hang out and craft.

      You are still welcome to attend and hang out with us even if you do not want to make pretty eggs.

      -----------------------------------------------------------------

      Blowing eggs is easy! You might screw it up the first couple of tries, so have spares handy. You will figure out the technique pretty quickly.

      To blow an egg:

      1) wash egg with soap and water.
      2) pierce pointy end of egg with a largeish sewing needle. Try to make this hole as neat as possible. If you have an electric drill, use the smallest bit you have.
      3) make a larger hole in the blunt end of the egg. This hole will be covered with a small button, so it does not have to be as neat. You should avoid creating any radiating cracks that could weaken the egg. You can use a variety of tools of this, I personally start with the sewing needle and then carefully enlarge the hole with the needle until it is about the size of a pea. An electric drill works great for this if you have one.
      4) insert a wooden skewer or similar object into the larger hole and thoroughly swish it around to break up the insides of the egg.
      5) hold egg over a small bowl. Turn it so that the bigger hole is facing downwards, and blow into the small hole. You should not have to blow too hard. If you are giving yourself a headache, stop and try enlarging one of the holes, or swishing the insides up better with the skewer.
      6) when you have blown out the egg, run a little water into the larger hole and shake it up to rinse out the insides a little, then blow out the water. You can skip this step if you want, the eggs will get cleaned out naturally during the dying process.
      7) make an omelet.

About Our Hackerspace

Arch Reactor was founded in 2009 by a group of friends who liked technology, programming, making, and pizza. Now St. Louis' largest hackerspace, Arch Reactor's growing membership continues to bring new skills, projects, equipment, and people to one place.

For a deeper understanding of what we're about, you should check out our explanation of hackerspaces, perhaps read about one of our members' projects, or (best of all) come meet us in person at the next open event!
