1. Pima County OEM R.A.C.E.S. Electronic Communications using Web-based Platforms Stan Hamnett, Webmaster, OEM RACES Webmaster Stan.Hamnett@pima.gov 1

2. I have been asked by Don Cox, Director of OEM RACES to give this presentation on how, we as a Team, can best communicate electronically using available web-based tools. I will give you an overview of the tools and then we will discuss each one. 2

3. We will discuss the following, not necessarily in any particular order. Who can upload and download files Membership lists Ease of use Cost 3

4. Google GroupSpaces OEM CMS Wiggio Yahoo 4

5. Google Limited to one email list at at time – per login email address – this applies to all email lists with the exception of Wiggio and Groupspaces, which will be discussed later. Not as many features as the other brands Members upload and download files 5

6. Groupspaces Can handle as many email lists as needed according to the plan you choose. Plans range from Free, to paid Members can upload and download files Track when a person opens email and if they don’t Email addresses can be added via.csv spreadsheet. 6

7. OEM RACES CMS No capability of managing email list Only “Authorized personnel” can upload files Anyone can download files 7

8. Wiggio As many lists as desired Free Members can upload and download files Members can go to website and read past emails Email addresses can be added via.csv spreadsheet. 8

9. Wiggio Host virtual meetings Easily add members Add Subgroups to the Main Group 9

10. Yahoo Limited to one email list Any member can upload and download files Membership – By invitation Ask for membership No limit to membership 10

14. Electric Principles VOLTS: electrical tern or electromotive force (EMF) Basic unit of electromotive is measured with a Voltmeter About 12 volts for mobile Radio Current: Measurement of flow Current is measured in AMPS Measured with AN AMMETER

15. CURRENT DIRECT CURRENT: Battery what your car has Normal car 13.8 VDC Alternating Current: What is in your house

16. Resistance Unit of measurement is OHM measured with an ohmmeter

17. CONDUCTANCE AND RESISTANCE COPPER is a good electrical conductor GLASS IS A GOOD INSULATOR

18. POWER Power is measured in WATTS This is what the meter on your house is measuring

19. Power Ratios (DB) 3dB is approximate a change of double (2 to 1) -6 dB approximate decrease change from 12 to 3 (4to 1) 10 dB approximate (10 to1)

20. ELECTONIC PRINCIPLES AND COMPONETS RESISTOR: used to oppose the flow of current POTENTIOMER CAPACITOR Stores energy in electric field The Farad is the unit of measurement Inductor (coil) stores energy in a magnetic field called inductance and measured in Henery’s

21. Parts A SWITCH A component to disconnect or connect FUSE component to protect circuit components Batteries CARBON-ZINE are non rechargeable and produce about 1.5 volts NiCad batteries are declarable and produce about 1.2 V

22. Parts are Parts Diode allows current to flow in only one direction ANDOD and CATHODE are the electrical parts and the cathode is usually identified with a Stripe TRANSISTORS used to control current flow GAIN term to describe transistors ability to amplify FET FIELD EFFECT TRANSISTOR is a transistor with a gat electrode LED) LIGHT EMITTING DIOD A RECTIE changes AC to into varying direct current

23. ELECTRICAL COMPONENENTS A CAPACITOR A RESISTOR A VARABLE RESISTOR A LAMP A TRANSISTOR A BATTERY A SIGNAL -POLW AINFLW-THROW A TRANSFORMER A VARIABLE INDUCTOR A ANTENNA A SWITCH A LED A INTERGRATED CIRCUIT
