DIY voltage-boosting LED driver  How is it assembled?  How do you convert an existing one to suit your needs? Hi! My secret helper wrote this post. She's in love with electronics, guitars, and cats. Kevin (teardownit.com editor) ANOTHER  secret helper. This guy can't write posts. We will consider the principles of how a step-up (boost) converter operates, and most importantly, current and voltage feedback, using a homemade LED flashlight as an example. Pulse power converters (or voltage converters, as they are generally called) have long been an integral part of electronic technology. The fact of the matter is, chemical current sources such as batteries and accumulators produce low voltage, while many other devices, primarily those based on vacuum and gas-discharge lamps, require high voltage. The basis for today's DIY kit is the ready-made ICSK034A from icstation.com. This is a kit for assembling a 5 to 12 volt step-up converter. This isn’t just a joule thief, but a stabil

When buying an HDMI extender over a twisted-pair network cable, it’s possible to inadvertently buy a kit that isn’t quite what you were looking for. You see, these extenders can be divided into two types: 1. Extenders that send a signal solely via a “direct” twisted pair network cable 2. Extenders that can send a signal either via a “direct” twisted pair network cable or a LAN (Local Area Network) The former type of extender uses a twisted pair network cable to transmit a direct signal between the transmitter and the receiver. This type of device cannot be connected to a LAN. These devices work by using the given manufacturer’s in-house created protocols, or by using the rather popular HDBaseT technology. HDBaseT technology makes it possible to “link up” devices from different manufacturers (for example, an HDBaseT receiver can be pre-installed in a projector). Typically, all extenders of this type transmit video and audio without delay or loss in quality. The range for these devices i
