2N4401 Description The 2n4401 is a bipolar junction transistor with an NPN junction that is used for general purpose amplification and switching. Conduction is carried out by both charge carriers, i.e. electrons and holes, in a bipolar junction transistor....
Saladin (saladin.vn) is a Vietnamese Insurtech startup, backed by global venture capitals since 2022. We provide a one-touch-solution platforms for diverse protections to the general Vietnamese public, Multiple Insurers – Multiple Products – Multiple...
Originally published in 2017. PDP-1 at Lawrence Livermore National Laboratory As you might have gathered from my projects, I am a bit of computer and electronics history buff. I’m old enough to actually remember using an 8-bit Heathkit H-89 computer...
2018 UpdateST gets AtollicYes, "almost 2018", update. Interesting to see as noted @Hamish with the link he posted, STMicro acquiring Atollic IDE that was classified in this review as the most efficient. That makes sense. VSCode rules overWhere...
Background At present, there are two types of lcd 3D printer on the market: FDM (Fused Deposition Manufacturing) and Light Curing 3D Printing. Among them, the FDM technology is more mature, the price is lower, and the market share is higher. You...
the smallest generator ac 230 V lighting 3 W Mr 16 led using a single neodymium sphere 10 mm diameter and a small Dc motor from a CD ROM, powered with a 1.2 V battery.
I’m David, and my goal with this repository is to demystify the word protocols in enven more detail then my previous article called IoT-Raw-Sockets-Examples, and proving that there is nothing to hard to learn. We just need to pass through the unknown...Before...
Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board and a piece of software, or IDE that runs on your computer, used to write and upload computer code to the physical...
Adopting frequency conversion technology and microelectronics technology, Variable-frequency Drive, a kind of power control, changes its working power frequency in order to control AC motor. The VFD is mainly composed of rectification (AC to...
Dear Sally,Thanks for your postcard! Was that a real antique or one of your amazing replicas? You have a real artistic sense, always have. It made me think back to when I met you, over a hundred years ago now! I would have said it warms the heart to...
This website shows simple test LED circuit that you can use to detect DC or AC small voltages. The AC signal will cause the LED to blink unless the frequency is above 100 Hz.You can also use a 1.5 V light bulb because 1.5 V light bulbs can turn on at...
A rectifier is a type of electronic component that is used to convert alternating current (AC) to direct current (DC). It does this by allowing current to flow in only one direction, which is why it is called a rectifier. There are several different...
The Ninja Tap is an adapter that allows to use up to 4 joysticks per MSX port (MSX Wiki).There is not much information available on such adapter, let alone the schematics.I wanted to build a clone of such adapter then I have started to disassemble a...
