Hack Something Night

Hack Something Night is a regular Tuesday meeting feature where people get together and attack a thing or project and make some progress on it. This week there were several projects being worked on, pictures and summaries below. If you have any questions or input on any of these please do join on on the mailing list or forum! Also if you worked on a project that I missed, let me know and I'll add it here.

A CNC laser cutter being build from scratch. Here the frame is built and the X and Y axis carriers are installed and belts and stepper motors are being added. When finished, it'll have sides and a hinged lid, with a vaccuum system to remove the fumes that result from laser cutting.

Weeding cut vinyl stickers, tweaking in a new logo design, look for these and other stickers to be available for purchase soon. Proceeds will be used to buy consumable materials and replace worn equipment at the space.

This will be part of the balloon project. On a breadboard there is an Arduino and a small radio that will be used to transmit the balloon possition, both for flight path tracking and recovery after it comes back down.

This bike needs a new pedal, so our resident Makerbot expert is designing one to be printed that will use the original shaft and bearings.

 

A box of remote control toys also appeared for use in future projects, thanks Andy Fisher!

Upcoming Events

Tomorrow

  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.
