"The goal is a site where the learning of electronics is hands-on and fun. And the SPICE circuit simulator is a great software tool to achieve that goal. It hit me the first time I used SPICE - simulating is fun! And because it's easy to use, I've spent a lot of time building and exploring circuits." - Rick

Wide-Bandwidth Dual JFET Opamp LF353

Dual JFET Opamp LF353

These devices are low cost, high speed, dual JFET input operational amplifiers with an internally trimmed input offset voltage. They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents.

e-Learning Resources – Physics at Exeter

Feedback and Temperature Control

Excellent Online Educational Pages at Exeter. Students and Teachers can get ideas on how to enhance and enrich the Science Education Process. A Sound understanding of Physics and Chemistry is needed for stepping into “Electricity and Magnetism”. We have to move young minds into Electronics even before High School, as a part of Science itself. - delabs

SPM-3 Heterodyne Level Meter

Wandel Level Meter

The SPM-3 is a broadband and heterodyne level meter whose frequency range is is designed for balanced 1 20-channel systems. It can be powered from a built-in rechargeable rechargeable battery or from the mains. Buffer operation is also possible. possible. The unit is easily transportable and simple to operate, making it well suited for the and is therefore well suited for the maintenance service. 

Why Wi-Fi gaining over RJ45

RJ45 LAN Cable

The speed of data transfer on a wired connection depends on Cable, Connector and the Crimping. Ethernet over Coax (EoC) co-axial cable. Optical and Gigabit Ethernet over Optic Fibers. Copper twisted pair and others are other means of Digital Data Transfer over Ethernet. Wi-Fi and WiMax helps freeing the user from wires. Remember Wired is more secure than Wireless. Intranet is safer than Internet.
