Solderless breadboards

Solderless breadboards are one of the most fundamental pieces when learning how to build circuits and prototyping simple circuits. A breadboard is a construction base for prototyping of electronics. Breadboard are the ideal way to check out small bits of circuitry that you’re not sure about. Originally it was literally a bread board, a polished

DC-4.0GHz RF Fixed Attenuator

RF attenuators are a universal building block within the RF design arena. I neeeded some RF attenuators for my electronics lab. I found this cheap product  DC-4.0GHz RF Fixed Attenuator from Banggood. They seemed to have pretty good specfications and features considering that the price is just slightly over 7 Euros for three attenuators: Frequency

The quest for a great text editor: A brief intro to Notepad++ Question “Vim or GNU Emacs?”  From those my answer is Emacs. But more and more I use other editors. One of my favourites on Windows is Notepad++. Notepad++ is easy to install, licensed under the GNU Public License (GPL), and the source is available on GitHub.  If you’re comfortable with Windows Notepad or WordPad, the Notepad++ interface will be

Fiber optic testing updates

Few days ago I read The remarkable evolution of modern fiber-optic connector inspection probes article tells about the current state of fiber inspection. Especially with multifiber connectors such as MPO, MT, and MXC microscopic connector endface dirt and debris cause light reflections and attenuation – the enemies of optimal optical signal transmission. Thankfully there now

Home reflow sees the light | EDN There are lots of claim to be workable solutions out there to reflowing boards at home – mostly involving kitchen appliances like toaster ovens and various sorts of hot plates and skillets. 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

Banana connector types A banana connector is a single-wire (one conductor) electrical connector used for joining wires to equipment. The term 4 mm connector is also used, especially in Europe,because the pin’s diameter is nominally 4 millimetres (0.16 in).The pin has one or more lengthwise springs that bulge outwards slightly, giving the appearance of a banana. The original plug consists of a cylindrical metal pin about 20 millimetres (0.79 in) long.However other
