Apps for Engineers
regarding your request for engineering-friendly apps (“Apps for Engineers,” Jan. 18), here’s one to look at:GPS Essentials (for Android), which is free.
Set all the parameters to field your
position at a tower site. It includes a beautiful, large, smooth magnetic
and marine declination compass (can be toggled), with declination offset — the only
app I know off where you can calibrate your phone’s compass too.
Hiking tracker, sunrise, sunset, moon
rise/set; set local time, UTC time; see your GPS satellite positions in the sky
in real time along with how many “birds” are flying in your view-sphere (GPS
must be phone-enabled in your settings).
It even ties in with Google Maps,
Google Earth or any other mapping app you have installed on your phone. I can
even get a minimum of three or four “birds” indoors with my HTC Inspire, which
is way better than my Delorme Geomate can do (will track a fix on your bearing
and location with a minimum of four “birds”). You can customize a “dashboard”
to see as many fields as you want in a scrollable table without having to go
into each backscreen.
A pro version is available for a fee,
but the free version is comprehensive as it stands. One of the best GPS
apps I’ve ever found. It works reliably and I haven’t found any bugs. It uses
the consumer GPS ground-measurement resolution.

iDVM by Redfish Instruments
A Digital Multimeter for iOS Devices
One app for the iPhone that I don’t
think you have covered is iDVM by Redfish Instruments. It uses the phone as the
display and interfaces to a wireless remote A/D converter box. Demo is free. I
don’t have the A/D box yet but it is on my wish list. Thanks for the articles!
Check the iSlipstick
iSlipstick and iSlipstick RF are apps that I wrote to help me
with basic everyday RF and electronic calculations. Having worked as a
transmitter supervisor for 25 years at a CBS O&O installation in
Philadelphia, I could have really used these apps back then.
I continue to work in an environment that requires RF and
electronic calculations, so I put into these apps what I found to be most
helpful for anyone working in the field.
I hope you find them useful and would love to hear feedback
for improvements via www.carry-onsoftware.com.
iSlipstick RF is among the apps
developed by Sam Virgillo, a former transmitter supervisor.
Apps I Find Useful
I work as a broadcast engineer and electrician and have used
several apps that help in both fields:
-AWG Metric Wire Converter by Intineo: Gives U.S. and metric wire equivalents
- Engineering Cookbook by Loren Cook Co.: If you’re working with fans and
motors to move cooling air etc.
- ElectroDroid by Demetrio Iero
- Electronica by Hacsoft
Developments: Great pinouts, scales and other useful tools
-RF Tools -VSWR+ by QubeCAD
-ToneDef by Hacsoft Developments: Excellent tool for modems etc., RF and
Just look for them by name. Great
