There are a lot of new people joining the engineering ranks. They are enthusiastic and eager to benefit from the hands-on experience that many Workbench readers possess.
When one of my engineering brothers and sisters mentions a helpful tip, I ask them to submit it for this column. They’ll often reply, “But everyone already knows this!” That’s not the case! So take a moment to share your advice with others through Workbench, the industry’s favorite tips column, and earn SBE recertification credit at the same time.
Get a grip
Today we have several products that might make your job easier.
Try lining the top of your workbench with a sheet of Con-Tact Brand Premium Shelf Liner. The engineering staff of Tyler Media’s KOMA(FM) in Oklahoma City uses this non-adhesive rubberized mat to prevent tools and equipment from slipping off workbench surfaces, as shown in the photo above. The matting comes in a roll and can be custom-cut for your specific need.
It’s available from online retailers or direct from the company. Browse the site to learn about a variety of adhesive, non-adhesive and cushioned liners suitable for various surfaces.
Bring the heat
Here is an inexpensive device that can be used as a temperature alarm or to control backup cooling fans or heating devices at a transmitter site.

Engineering consultant Frank Hertel, principal at Hertel Engineering, told us about a version of the Uxcell Mechanical Thermostat that contains two independent mechanical thermostats in one housing.
Each thermostat’s switching contacts are electrically isolated. At 120 VAC the contacts are good for 15 Amps. At 220 VAC, the contacts will handle 10 Amps.
Temperature is shown in Celsius; the range of operational adjustment is 0 to 60 degrees C, which is 32 to 140 degrees Fahrenheit. Frank says most thermostats do not have this range of temperature, making the device suitable for the swings at some transmitter sites.
You could use it to trigger a backup exhaust fan should your main air conditioning fail.
The best part is that it costs around $16. Visit your favorite online supplier and search “uxcell mechanical thermostat.” If you install one, let Workbench readers know how you used it. Email your suggestions and a high-resolution photo to me at [email protected].
Shine a light
You know what it’s like to work under a console or in the back of an equipment rack, just wishing that you had a source of bright light.

As we’ve discussed, many engineers use LED “rope” strands to brighten these areas; others rely on small battery-powered puck lights, with mixed results.
Your choices have improved thanks to development of high-intensity LEDs and improvements in battery technology. One to consider is the BLS T401 Super Bright Closet Light, which gets strong reviews. The light provides 6000K cool white light of 200 lumens and includes a motion sense mode that will turn it on when you approach.
You can attach its small mount to the wall with 3M adhesives or screws, both provided. Magnets in the light hold it in place and also allow you to detach it easily for use as a flashlight, kind of like a light saber!
BLS says the battery will last six months between charges when the light is used in the intermittent operation mode. It can be charged using a USB-C cable (not included).
Why not place one of these inside the door of your transmitter building? A pack of two costs less than $60. Find the BLS T401 Super Bright Closet Light on Amazon.
Label that thing
And Steve Tuzeneu, chief engineer for Hall Communications in Lakeland, Fla., commented on our column in February, “Not All Labels Are Judgmental.”
Steve says that he uses labels on equipment to keep track of RAM battery replacements. UPS units get similar treatment so Steve knows when next to change the batteries.
Little habits like this are part of good engineering practice. They take only a moment, yet they could save you from a catastrophe. Where do YOU like to put labels?
