CB of the Day! Trinket - Mini Microcontroller - 3.3V Logic - MicroUSB

Trinket may be small, but do not be fooled by its size! It's a tiny microcontroller board built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project and low-cost enough to use without hesitation. Perfect for when you don't want to give up your expensive dev board and aren't willing to take apart the project you worked so hard to design. It's our lowest-cost Arduino-IDE programmable board!

Near Field EMI Probes: Any Good?

Near Field EMI Probes: Any Good?

[Learnelectronics] purchased some near-field EMI probes for his tiny spectrum analyzer for about $5 on sale. Could they be any good at that price? Watch the video below and find out. The probes arrived as a kit with four problems: three circular ones for sensing the H field and a stubby probe for sensing E fields (although the video gets this backward, by the way). There’s not much to them, but…

Gas Filled Tubes | Conduction in a Gas

INTRODUCTION OF GAS-FILLED TUBE In the vacuum tubes, the electrons pass from the cathode to anode in a vacuum. In that type of tubes, extreme care is taken to generate as perfect a vacuum as possible to prevent ionization of gases and the resulting large uncontrolled currents. It may be mentioned here that the logic of the triode is the fine control of free electrons within the valve through the electrostatic fields of the grid and anode. If gas is present even in a little amount, the electrons pass from cathode to anode will be the reason for ionization of the gas. The ionized molecules would interact with the fine control and it makes the device useless amplifier. In some applications, fine control of electrons within the valve is of less importance than the efficient handling and turning HIGH LOW OR on-off of huge currents. In such a condition, some inert gases (e.g argon, neon, helium) at small pressures are purposely introduced into the valve envelope. Such tubes are called as gas-filled tubes. The gas-filled tubes are able of doing many jobs that vacuum tubes never perform and which are especially useful in industrial systems and control circuits. In this chapter, we shall focus our attention on the most important types of gas-filled tubes having special reference to their characteristic properties. Gas-Filled Tubes A gas-filled tube is essentially a vacuum tube with a small amount of inert gas at low pressure. #coldcathode #conductioninagas #electrical #electricaldepartment #electricalengineering #electricalfacts #electronic #electronicdepartment #electronicengineering #electronicfacts #Gasfilledtube #historyofelectronic #learnelectronics #schoolofelectrical #schoolofelectronic Read the full article
