Welcome to a new InTheMail, the series that will make your account balance go negative or so I’ve been told by my viewers. I admit it myself, when I watch these kind of episodes from other youtubers and i see something interesting, there is no going back, I have to order that stuff.
Here is a list with the items shown in this video:
3W RGB Flashing Rainbow LED
Mini LCD Digital Humidity Temperature Meter
ACS712 Current Sensor Module
TTP226 8 Channel Capacitive Touch Sensor
W25Q32B Winbond 32M SPI Flash Memory
Universal USB breakout board
Adjustable DC-DC Step-Down Converter
5.8GHz Microwave Radar Sensor

Links for all of these items will be in the video description which is visible on youtube.
Today I’m going to be building a complete DIY analog bench power supply. The actual analog power supply kit (0-30V 0-3A) that I’m going to be using, is this one, it was shown and assembled in voltlog #8. Besides that I’m going to be using this plastic enclosure which I think is quite nice and perfect for such a project, this one can also be found on banggood and there will be links in the description for all the items used in this build.
Everybody knows this is a great scope for the money but as usual test equipment doesn’t use the best solutions in terms of cooling fans and associated hardware. They care mostly about keeping the unit cool and not about the noise the unit makes because usually these are used in environments where multiple equipment is run at the same time, the noise level is already high so it doesn’t matter much if a small 50mm fan is adding noise.
But it’s a totally different story for us hobbyists that are using these pieces of test equipment indoor, in our homes. We usually want units with passive cooling or with silent fans.
