As if Dymo adding DRM to force you to use their labels wasn't low enough, they have been BUSTED reusing their old 450/4XL Amazon listings in order to keep all their old positive reviews to make you think people are positively reviewing their new 550/5XL DRM model!
This deception should be reported to Amazon.

Can a product work without ANY bypass capacitors?
Dave has some fun finding out if "Muntzing" the Gigatron TTL computer works, i.e. removing all the bypass capacitors.
Lots of interesting talk on bypassing, grounding, probing, signal integrity, ground loops, loop area, noise and crosstalk.
TLDR; Don't remove all your bypass caps, they are important!

Dave plays around with converting a toaster oven into a surface mount SMD reflow oven with a beginner kit and controller from Beta Layout.
Includes basic calibration and thermal profiling of the oven.
Also a look at an example PCB from PCB-Pool, and reflow of an example board with lead-free solder paste.
And using an Agilent bluetooth multimeter to remote log the temperature.
