Arduino Night (31 Apr, 7-10 PM)

I am super late getting to the slides for this class O.O

The basic plan is to play with transistors to control LEDs and DC motors. If we get through everything, then the next class will hopefully cover H bridges for reversing DC motors. The agenda is short since the class could go way over the allotted time.

Feel free to bring your own DC motor. We have a small collection of motors at the space.

Agenda:

  1. What is a transitor?
  2. Why use one?
  3. Look over datasheet
  4. Hands on with LEDs
  5. Hands on with DC motors

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

Provided Items:

  1. Transistor (part number TBD)
  2. DC motor

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!

Arduino Night (17 April, 7-10 PM)

Per a request at the last class, we will be writing to and reading from SD cards.

Please bring an SD card if you can. There will only be two available for use!!! Also, the cards must be SD, not the smaller cards. All cards should be 8GB or less and be formatted to FAT16 or FAT32. Larger sizes might work, but I haven’t tested it.

Agenda:

  1. Look over the LC Studio breakout boards
  2. Interfacing with SD cards
  3. Resistor dividers
  4. Wiring up the breakout board
  5. Run demo code
  6. Create custom code to write ADC samples and then read them back

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.

  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
  7. Variable resistor (potentiometer) for setting the contrast
  8. SD card if you have one. Preferably <= 4GB

Provided Items:

  1. LC Studio SD card breakout board

UAS Hackathon1

This weekend marks v1.0 of the Unallocated Space Hackathon.

That’s right, another 24 hours filled with pure unadulterated caffeine-fueled productivity and, of course, wompster.

R00ster will also be starting off the day prior to all the hacking, with another workshop on Git. If you don’t know Git, you should definitely check this out!

For more information and to register for the event, Click Here.

“More pizza. More code. More hardware hacking. More sleep deprivation.”

It’s also just plain, more FUN. Hope you can come out and join us!

What do you want to see at Unallocated Space?

Unallocated Space has been open almost 4.5 years at this point and we have done a huge variety of projects and had a presence out in the community at a variety of events. Check out some of them at our outreach page. We are the most unique space in the area as far as the diversity of events and classes we do as well as the willingness to do all these events for free.

Everyone has different ideas for what they want the space to offer. Feel free to share your idea even if you don’t know enough to teach it and/or time to organize a event around it.

For example, I just started a interest check on our google group/mailing list about a class on PLCs, RTUs and the systems that use them. What ideas do you want to see/learn about?

Arduino Night (20 Feb, 7-10 PM)

We are getting back to LCDs this week. The last time we dealt with a 16×2 display, we used the LiquidCrystal library. This time we are going to ‘bit bang’ the LCD by hand. The idea is to learn how to control external devices for which you don’t have a library.

Agenda:

  1. Wiring up the 16×2 LCD
  2. Quick look at the datasheet
  3. Explain how the various commands work
  4. Create code to initialize the display and show a blinking cursor
  5. Create code to display ‘Hello World’
  6. Time permitting:
    • Moving the cursor
    • Adding custom characters

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.
