For decades, millions of families relied on inexpensive cars to get from home to work and school. But over time, as carmakers shifted towards luxury vehicles, the budget car began to disappear.
Fast cars don’t have to come with a sky-high price tag or crazy insurance premiums. Whether you're after weekend thrills or a fun daily driver, there are legit options out there that won’t empty your ...
The components are inexpensive, consisting of a P-MOSFET (for use in the positive rail) with a dual PNP transistor and two resistors. Q1 and Q2 form a current mirror circuit that act as a differential amplifier which responds to the voltage drop across the MOSFET.
Just wondering what can be used as an inexpensive potting compound. The commercial solutions seem fairly expensive at $40.00 for 350ml. The small 12V timer...
The device is not inexpensive (≈$5 USA) but its simplicity and low parts count in this application means the overall parts and assembly costs will likely be significantly less than using a discrete parts design or cheap IC regulator such as the LM317, with all the associated circuitry required to perform these same functions.
Sadly, the days of inexpensive PCBs from China are over for US citizens – you all know why so we need not discuss that. The prices from China still beat the prices from US sources in most cases, but even then, there is uncertainty in what the real cost may be with the fluctuating rule changes...
