Arduino Night (19 June, 7-10 PM)

Continuing the trend of motor control and transistors, we will be driving unipolar steppers motors. The motors will be provided since having varying stepper motors can be troublesome.

It is suggested to bring a full sized bread board since this will take up a little bit of room!

Agenda:

  1. What is a stepper motor
  2. Uses of stepper motors
  3. How do stepper motors work
  4. Wire up using transistors
  5. Write code to spin one direction
  6. Modify the code to spin both directions
  7. Wire up using little driver boards

If you cannot attend the class in person, E-Mail arduino@unallocatedspace.org and ask to be added to the Google Hangout. The hangout will be started just before class (6:45-7:15 PM). If you have not gotten an invite by 7:15 PM, then please E-Mail arduino@unallocatedspace.org.

The slides for the upcoming and previous classes can be found here. The slides are generally made during the three days before a class.

Required Items:

  1. An Arduino board of some kind (Uno, Due, Mega, Boarduino, Duemilanove, etc)
  2. If your board does not have USB programming built in, you will need a programmer (AVRISP, Bus Pirate, Bus Blaster, AVR Dragon, another Arduino, etc)
  3. Breadboard (the long one if possible, though the small square-ish ones are okay for now)
  4. USB cable for your board and/or programmer
  5. Laptop with the Arduino IDE installed (Linux, Windows, or Mac)
  6. Jumper wires for your breadboard (male-male and either female-female or female-male) (these are provided if needed)

Provided Items:

  1. 28BYJ-48 stepper motor
  2. Simple darlington driver board

Since Unallocated Space runs off of donations, we would like to mention that the recommended donation for this class is $5. It is by no means a requirement, but it does help us keep the lights on! Attendance to the space, and this class, is 100% free to all!

Retro LAN Party (1995-2005)

We will be having a LAN party, focusing on the 1995-2005 decade!

This is a themed event, to the greatest extent possible, even down to the clothes you wear! Here are some examples:

* Bring music that you listened to during those years.
* Bring some old shows or movies with you that were popular then. Maybe we can have those playing in the background?
* Wear clothes that were popular during that time. Got an old favorite band t-shirt?

Recommended PC stats:

* Refrain from using an operating system newer than Windows 2000.
* Try to use an old PC, rather than an VM. Time to dust off your old gaming rig!
* Install IPX/SPX. It would be cool to avoid TCP/IP if possible.
* If all else fails, just use a VM or DOSBox, an x86 emulator with DOS.

We will be playing games like:

– Age of Empires
– Command & Conquer
– Warcraft 2 – Tides of Darkness
– Unreal
– Quake
– Doom II
– Half-Life: Counter-strike (beta 5?)
– Diablo

Because of the age of these titles, some (not all) games will be considered abandon-ware.

Agenda:

– Saturday @ noon – Doors Open
– 1:00 PM – Gaming Starts
– 5:00 PM – Pizza Arrives ($5/person) & More Gaming
– 11:00 PM – Take Out & More Gaming
– 5:00 AM – Donuts / Coffee ($2/Person) & More Gaming
– 11:00 PM – Take Out & More Gaming
– Sunday @ noon – Gaming Ends

Since Unallocated Space runs off of donations, we would like to mention that the recommended donation for this event is $5. It is by no means a requirement, but it does help us keep the lights on! Attendance to the space, and this party, is 100% free to all! Thank you for your support!

June 8th Electronics Class

Tonight at 7pm we will cover power factor. I will also have a bad circuit board for everyone to take a look at and discuss what the issues with it are. Fun trouble shooting! Time permitting, we will also have some labs.

Computer Lab!

Howard County STEM festival Today!

This is a reminder we will be at the HoCo STEM festival at Howard Community College today from 1pm to 5pm. We will have two tables setup with a variety of information and items about Unallocated Space. If you have questions about this event or would like to assist with the table, contact Forgotten ( Forgotten [at] unallocatedspace [dot] org )

Check it out: http://stemulatingminds.weebly.com/

Field Day

This is the Big Ham Radio event of the year. This is our opportunity to get the word out to the public about Ham Radio and UAS. Everyone is encouraged to come out and see our operations. Plus if your interested, we’ll put you on the radio to make a few contacts and help us improve our scores from last year!

We will also need assistance for the set up and tear down phases of the operations. Tear Down volunteers are needed most as this operation goes for a straight 24 hours and our core guys will be exhausted and working on fumes… Any help will be greatly appreciated at that point!

  • Friday June 26th, 4pm load up at the Space and Haul to Security Square Mall.
  • Saturday June 27th 7am finish setup and start Field Day Ops.
  • Sunday June 28th Continue Field day ops… Tear Down in the afternoon and bring back to the Space.

Space Improvement Day – Saturday, June 6th!

It’s that time once again to roll up our sleeves and give the space some TLC. Here’s the deal:

June 6th, 10am, we’ll be hitting the following things:

  • Wiping down tables.
  • Cleaning floors.
  • Cleaning fridge/microwave as needed.
  • Cleaning bathrooms.
  • Tidying work areas and storage area.
    • The storage/networking area has gotten disorganized.
    • Things need to be put back in place.
  • Moving things to the outpile, as appropriate.
    • If we have enough hands on deck, someone can pull outdated books from the library to make room for newly donated ones.

Please try to drop by with a helping hand. We could really use your help in organizing, cleaning, clearing, and making the space better for your future visits.

We’ll either grill out for lunch or order in. Either way, there will be food!

You can RSVP here (if you use Meetup): http://meetu.ps/2JJvNK

Trailer Build Days

WE NEED VOLUNTEERS to hold ropes for safety.  At least 4 is preferred.   More is helpful…. You don’t need to be a gorilla to help out here.  Just be able to hold a rope to help keep the tower steady.

  • Friday May 29th, 4pm to 10pm (This will be outside.)
  • Friday June 5th, 4pm to 10pm (This will be outside.)
  • Friday June 12th, 4pm to 7pm (This will be outside.)

Also, Friday June 12th is our monthly Ham Radio Night from 7pm to 10 pm. This will be our last planning session before Field Day.

If you haven’t yet seen our portable tower antenna trailer, you should definitely come check it out!

Arduino Night (15 May, 7-10 PM)

Last time we covered basic transistors. Just turning an LED on and off and driving a DC motor. This time we will look at creating an H bridge to drive a DC motor forwards and backwards. We will also be going a little more in depth about transistors.

Feel free to bring your own DC motor. We have a small collection of motors at the space. Also bring a multi meter if you have one. It’s nice to be able to check the current draw to make sure there are no shorts.

It is suggested to bring a full sized bread board since this will take up a little bit of room!

Agenda:

  1. Review of transistors
  2. Functional difference between PNP and NPN
  3. Explanation of an H bridge
  4. Review datasheets
  5. Wire up the H bridge
  6. Write a little code
  7. Drive a DC motor with a 9 volt battery

If you cannot attend the class in person, E-Mail arduino@unallocatedspace.org and ask to be added to the Google Hangout. The hangout will be started just before class (6:45-7:15 PM). If you have not gotten an invite by 7:15 PM, then please E-Mail arduino@unallocatedspace.org.

Provided Items:

  1. Transistor (part number TBD)
  2. DC motor
  3. 4 Diodes
  4. 9 Volt battery
  5. Alligator clips (for the battery)
