Fiber optic termination and splicing

We terminate fiber optic cable two ways – with connectors that can mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear or with splices which create a permanent joint between the two fibers. According to Which field-termination method best fits your fiber-optic LAN? article over the

DIY optical power meter with SFP module and Arduino idea

Fifer optics power meter is an important tool for debugging fiber optics networks. I have earlier tested a cheap commercial fiber optic power meter a at Fiber optics power meter posting. Hardware hackers ares famous for building their own test equipment. The basic operation of optical power meter is quite simple: take a suitable detector,

Everyday more things become Internet-connected things. They have sensors and can communicate with other things, and help us perform tasks like never before. Especially at home. Home automation is made possible by amaetuer developers and tinkers because the price of microcontrollers with the ability to talk over a network continue to drop.

People Are Using Old Laptop Batteries to Build Their Own Versions of Tesla’s Powerwall

https://futurism.com/people-are-using-old-laptop-batteries-to-build-their-own-versions-of-teslas-powerwall/ Tesla’s Powerwall was intended to provide a convenient way for homeowners to store electricity for future use, such as when the power goes out. But with a $5,500 price tag, they haven’t been affordable for many consumers.  Some who had been interested in the tech, however, decided to try to make their own: constructed their own powerwalls by utilizing

Tiny AI Devices Invade the Maker Movement

https://blog.hackster.io/tiny-ai-devices-invade-the-maker-movement-928c01b185df It is no secret that AI is among the top growth areas in technology today. Interest Deep Learning has caused an explosion of industry investment into software such as Facebook’s Caffe2 and Google’s TensorFlow frameworks. There is the theme of providing small edge devices with more intelligence has grown stronger. More and more inventive developers and teams seem to

An interesting approach by David Sanz Kirbis uses a halogen shop or flood light as heat source and enclosure.   More info: David’s project write-up Controller

Probing Ethernet cable with an oscilloscope

This article talks about measuring 10 Mbit/s (10Base-T) and 100 Mbit/s (100Base-TX) twisted pair Ethernet signals. Those standards use two wire pairs for the communications and use differential signaling. Differential signaling is a method for electrically transmitting information using two complementary signals. The technique sends the same electrical signal as a differential pair of signals,
