The Mill Arrived Today! Yippee!

Bridgeport-1

Thanks to the effort and generosity of a committed group of PS:1 members and project donors, we now have a Bridgeport milling machine. Special thanks go to Zlotan for keeping up the project momentum. Thanks to Tucker for setting the goals and doing a bunch of research and leg work.  And a big thank-you to Bart Dring for hooking us up with a sweet deal on a great machine and arranging the move.

Bridgeport-2

There will be more to say and more to report as we integrate the mill into our shop. Stay tuned for further announcements.

NERP Tonight: Big Blinkies

Tonight at NERP, Yours Truly will show a couple of ways to interface from low level logic to 120VAC to control lights, motors, etc.

It’s well understood that small microprocessors have very little power available on their output pins. A load controlled by the processor can be AC or DC, and low or high voltage. The interface circuit has to amplify the logic level signal to the appropriate power for the load.  An unusual method (Ok, it’s a hack) for controlling 120VAC light dimmers involves adding a photocell to a commercial wall dimmer, and coupling the photocell to the processor via a PWM’ed LED. (This method of interfacing involves working with dangerous voltages and currents. It is presented for demonstration purposes, only. Don’t try this at home. Or do. It’s your choice.) A simpler method of interfacing to 120VAC uses solid state relays for on-off control. We’ll see SSR’s  used for making a big blinky for large lamps.

NERP Tonight: Ste on the Launchpad

Tonight at NERP, Ste Kulov will introduce the MSP430 line of microcontrollers from Texas Instruments. His talk will focus on using the MSP-EXP430G2 Launchpad kit.

The MSP product line from Texas Instruments contains an extensive variety of microcontrollers varying in size, peripherals, etc. MSP microcontrollers are know for being 16-bit, very low power, feature-rich, and low-priced. The development boards are called Launchpads. Open source software for developing on Launchpads has been scarce and not condoned by TI. This is changing however as TI has joined the msp-gcc project in collaboration with Redhat. One outcome to date is the energia development tools, which are a fork of the Arduino tools.

http://energia.nu/Guide_MSP430LaunchPad.html (see the pix of Launchpads)

Here’s what Ste says he’s likely to cover. (It’s a lot, so we may run a little over time).

1.) Talk about the MSP-EXP430G2 Launchpad kit and what comes with it.

2.) Very brief overview of Energia, which is software that turns your Launchpad into an Arduino.

3.) Introduce Code Composer Studio, which is the official software used for most Texas Instruments software development.

4.) Basic Boolean algebra review.

5.) Go over simple tasks such as setting, clearing, and toggling bits.

6.) Run a simple “Hello World” LED blink program.

7.) Run through the project I had to create for my job.  It uses Timers, Interrupts, and the Low Power modes.

CNC Build Club: Shapeoko 2 Demo

Shapeoko

 

At the next CNC Build Club, on Thursday 10/24/2013 at 7:00pm, we are going to have a demo of the, soon to be released, Shapeoko 2 CNC router.  The ShapeOko was designed by local inventor, and PS:One friend, Edward Ford.  The original version was extremely popular.  The new version adds many new features.

  • Larger work area.
  • Easier to expand
  • Open front and rear for feeding stock through
  • Dual motor Y axis is now standard
  • More ridged
  • Belts lay flat and are easier to install

Shapeoko

 

It will go on sale at Inventables very soon.  Inventables will also be giving away one milling bit starter kit at the meeting.  This a a kit of 5 solid carbide 1/8″ diameter bits.  It includes 2 spiral upcut bits, 2 straight flute bits and 1 ball end mill.  You must be registered on Meetup for this meeting and present to  be eligible for the bit kit.  The meeting is open to members and non-members.

NERP: Implementing MIL-STD-1553 with 3 Beagles

Tonight Trefor Delve will present a distributed simulation development making use of three Beagle Bone Blacks as part of the network. The simulation is used as a proof of concept for a general purpose, configurable simulation platform making using of public domain software.

Mil1553_timingMIL Standard 1553 bus timing [wikipedia]

The presentation will introduce the principles of the MIL Standard 1553 data bus, show a simulation with simulated hardware and demonstrate the same software running on distributed Beagle computers making use of the Beagle’s ADC, PWM and SPI interfaces.

The presentation will also demonstrate the use of the QT widget set to allow remote virtual hardware to interact with the Beagle simulation.

The presentation will demonstrate the setup of the ADC, PWM and SPI interfaces using the system capabilities.

NERP Tonight: QT and Steppers

NERP Tonight: QT and Steppers

 

Tonight at NERP, we’ll have a show and tell about the PS:1 entry in the Element14 hackerspace challenge.(http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/06/12/beaglebone-black–the-2013-hackerspace-challenge/)We’ll highlight use of the QT framework and gui tools on the Beagle Bone Black to run the stepper motors on the pick and place machine. There are always challenges in getting a new platform up. One challenge has been resolving version problems with the QT3 to QT4 transition on ARM. We’ll find out how that’s going. Also we’ll also have a tour of the system’s Z- and θ- axes mechanism and find out what the test results were on using some very small stepper motors to drive the head. As a bit of improvisational comedy, some of the tests will be done live during NERP! Yow!

CNC Build Club – Gonzo Build with Moto!

Make With Moto

We have a very special event planned for the next CNC Build Club meeting on Thursday, July  18th.  We are going to do a Gonzo Build with the Make With Moto crew.  Make With Moto is a Velcro covered Sprinter van filled with making equipment that is touring the country.  In addition to the making equipment they have a bunch of unlocked and hacked Android smartphones.  They have been doing hack-a-thons around the country.

BL9LF5vCQAIlv6F

We thought it would be awesome to do something that combines our CNC hacking skills with their  phone hacking skills.  We would temporarily remove the “a-thon” and do a one night Gonzo build.

The plan is to do a digitally controlled camera slider.  The phone would replace the camera and control the motion.  We are still seeing what is feasible on the phone control options, but ideally you could control the phone from a second phone and view live video or snap shots from the slider phone.

It will probably look similar to this camera slider that was done in the past, but it will have a mount for a camera and have all the drivers on the slider.

Inventables will be supplying all the CNC materials.  As the details get more firmed up, I will edit this post so check back later.  If you have any other ideas, let me (Bart) know.  We may be able to get materials for multiple versions.
