What’s inside the new FLIR TG165 Visual IR Thermometer / Thermal Camera using the new Lepton sensor?
How does it compare to the FLIR ONE & FLIR E4?
Does it have a calibration shutter?
Does it have any extra capability built in ready to be hacked?
How easy is it to open? (SPOILER – it’s a BASTARD!)

A very brief look at the new WENS 540 Debug Meter with Charles from Trio Test at the Electronex show stand:
This is NOT a review, or my normal blog content, it’s just a quick look because some people may be interested in it. So please, no silly complaints.
A combination 10MHz oscilloscope, 50000 count meter, 8 channel logic analyser, data logger, serial protocol analyser, and digital pattern generator.

Dave walks around the Electronex 2014 electronics exhibition at the Australian Technology Park, after hours when no one is there, and takes a peek at every stand.

Dave explains a big trap in high frequency measurement with your oscilloscope. Based on a viewer request, Dave demonstrates how to incorrectly and then correctly measure the signal output level over frequency of your function generator using your oscilloscope. Some whiteboard transmission line theory is thrown in as well.

What’s inside one of those omni-directional laser barcode scanners you use at the supermarket, and how does it work? Motorola / Symbol LS9208

Dave explains, shows, and measures a potentially big trap with using high value ceramic capacitors. Is your 10uF capacitor really 10uF in your circuit? You might be shocked! Those humble X7R caps you think are a “stable” dielectric? think again… Class II and above ceramic capacitors can vary their capacitance drastically with DC bias voltage level and also the applied AC voltage.

Dave tears down Sony’s first digital camera that used removable media, a 3.5″ floppy drive! The 640×480 resolution 0.3Mpixel 1997 vintage Sony Mavica MVC-FD7

Dave shows you a handy tip on how to see *through* a product using a Flir thermal imaging camera with the cover *on*. Thus being able to maintain the correct airflow, whilst at the same time being able to view the thermal map as if the cover was off!
