5 Best Bench top Multimeters (2019)

Posted by Tommy Reed on Dec 31, 2018 11:21:00 PM

Go into any electronics lab and you will undoubtably see a bench top multimeter.  The humble bench-top multimeter is a staple of any lane and is one of the most fundamental and highly used pieces of test equipment for electronic design.

As the name implies, the multimeter is useful for a wide range of measurements and tests.  Bench top digital multimeters, or DMMs, can be used to to make the basic (Ohm’s Law) measurements:

  • Measure resistance
  • Measure voltage
  • Measure current

5 Great Engineering Laptops (Plus Free CAD Tool Guide)

Posted by Bliley Technologies on Dec 31, 2018 11:17:00 PM

Finding the Best Performing Engineering Laptop


Our engineering team at Bliley is growing, which is great, but it also introduces some new challenges for small business like ours... finding the best performing engineering laptops for our engineers.

We want to give our engineers the best tools available and create an environment where they can be their most innovative and do the best work of their careers.  Of course, a key to this whole equation is the technology they use day-to-day to get those next generations products designed. We recently kicked off a search for the best laptops that are perfect for engineering workloads. As you can probably imagine, the ideal laptop for an engineer needs to have great compute and graphics power.

The battery life needs to last most of the day (because what’s the use of getting an ultra-portable engineering laptop that has to be tethered to a power outlet all day?!?).  The CAD tools an engineer relies on every day require a lot of memory to run smoothly, and most engineers prefer to work with multiple monitors, so expandability is important too!
