Machining Project

FCW recently offered a Beginning Machining workshop, covering basic Milling, Drilling, and Turning operations.  The workshop allowed the participants to make a small air/steam wobbler engine.  Rich Goldner was the instructor and there were seven participants in two groups. The workshop took 16 hours spread over 4 weeks.

Raw stock of Aluminum and Steel was used in the project.  The base was cut, faced and drilled, the cylinder cut, faced and drilled, and the piston, crank and flywheel turned on the lathe.  The CNC mill was used for the milling and drilling operations.  Besides the milling, drilling and turning training,  the project also involved the setup of the mill and lathe, tapping, and precision measurement.

This workshop was restricted to current members of FCW but another is planned that will be open to the public.

Digital Electronics Workshop

 

This Summer, FCW held a workshop in Digital-Electronics: Gates.  The five participants were introduced to the essential gates (AND, OR, NAND, NOR, XOR, XNOR, and NOT) that make up all digital systems.  Hands-on lab exercises using digital trainers and solderless breadboards allowed the participants to connect the “chips” to switches and indicators so as to illustrate the basic logic functions.  Describing  digital circuits using logic diagrams, truth tables, and Boolean equations was also introduced.

The workshop was conducted by Michelle Suddreth, who has 30 years of experience with digital design and troubleshooting.

This is the first of 5 workshops in digital electronics.  In addition to  the workshop on Gates, additional workshops are planned as “MSI – Encoders, Decoders, and Multiplexing“, “MSI – Flip Flops, Counters, Shift Registers“, “Sequential Circuits“, and “Introduction to VHDL“.

These should provide enough information to allow additional circuitry to be used with microcontrollers or PLDs.

Things happening at FCW

FCW is working with Tony and Mike (the building owner) to create a “Haunted House” on Oct. 26, 27, and 31.  We are planning for 9 sets in the “pole area” behind our space.  The event will be free for the public.  Any help will be appreciated in the setup or operation of this event.  Spread the word, especially to those who may not be able to afford such events for their kids.  Contact Ross if you would like to help.

FCW has been donated a 4×4 foot CNC wood router.  It is currently in the process of being re-assembled and calibrated.

The large dust collector has been tested and works well on a 220V 20A circuit.  We will be pulling a new 220V circuit to the woodworking area to handle it.  Rick and Ross need some suction duct for it.

Work on the 3D printer has been suspended for now until some of the other projects have been completed.

We are waiting for cooler weather to put the Butternut antenna on the roof.

We got a letter from the IRS concerning the status of the 501(c)(3).  It was sent to the next level for additional checking, so we wait again.

We are planning an open house on December 15, with photo sessions for kids and Santa (ie. Warren).

We are negotiating for some additional space.

If anyone knows of any public relations opportunities, or ideas, be sure to tell Colin.

Have a good Labor Day.

Amateur Radio Field Day

On June 23-24, FCW operated a Field Day Station for the ARRL Field Day.  The purpose of Field Day is to allow Amateur (HAM)  Radio operators:

-To test equipment

-Gain experience in operating under non-optimal, or emergency conditions

-Introduce the public to Ham radio

-To socialize

Field Day is in the form of a contest in which Hams contact stations all over the country.  This was the first serious use of the FCW station – call sign K4FCW, and so, was essentially, an experiment.  Despite our main antenna not being available, things worked out ok as two HF transmitters were active.  Even with temporary antennas the station made contacts with 29 states and 2 provinces.    Thanks to Buck for the loan of some gear and Ross for the loan of a slushie machine.  We now know what to improve for next year.

Meeting Modifications

Due to numerous space, personal, and common projects, FCW will start having a project/build meeting each Tuesday at 7PM.  In addition, Business meetings will be alternate Saturdays, with the other Saturdays being project/build meetings.  Saturday meetings will continue to be at 3PM.

Open House/Cookout (Phase II)- June 2

FCW is nearing the end of Phase II of construction at the site.  This will mark the opening of new areas.

  • The classroom – will be able to handle 16-20 students in a seated environment.  The room can also be used for computer training, demos, and movies.
  • The model shop– will eventually house the model railroad which is to be moved in this Summer.  It will also house model making equipment and tools for making scenery, props, and models for railroad, airplanes and others.  There is a large viewing window  in the railroad area.
  • The ham radio station – K4FCW.  This will start off with HF and VHF equipment.

These will join the Machine Shop, Electronics Shop, and Wood Shop to support FCW activities.

The opening of these areas will be celebrated with an Open House and Cookout on Saturday, June 2 from 10AM to 6PM.  The day will be filled with:

  • Tours
  • Demonstrations of various science and technical topics
  • Games
  • Activities for all ages
  • Food

Guests are welcome!!

 

Electronics Workshop Successful

Rich instructing the class

The Electronics Workshop at FCW on April 28, 2012 can be considered a success.  Rich Goldner conducted the 4 hour workshop for four participants, covering  various electrical topics including:

  • Parameters – Current, Voltage, Resistance, Power
  • Measurements – using a DMM
  • Use of a solderless breadboard
  • Component identification
  • Basic series and parallel circuits
  • A transistor as a switch
  • The 555 timer

Thanks to the Granite Falls Radio Shack, who provided materials for this workshop.

This is the first of numerous workshops which will include electronics, soldering, machining, ham radio, programming, and other topics.
