I designed a small device that controls GPRS data transmission and reception using MSP430. Later, the teacher gave me some suggestions on what to do if the msp430 or gprs crashed remotely. He asked me...
[align=left][color=rgb(34, 34, 34)][font="][size=4]The transistor collector DC circuit is the circuit between the collector and the DC working voltage terminal. This DC circuit is the circuit with the...
My understanding is that the power supply output voltage is a constant 12V, and the output current varies from 0 to 2A depending on the load size. Is there any problem with this?If this is the underst...
Important things to say in advance:
I would be satisfied if I could understand the data that is ultimately exposed to the air during a Bluetooth transmission, and then parse and understand it.
I searc...
Recently I needed to do a sound project, so I wrote a demo using lpc1114, using two timers to play wav files. I sent it with my phone during the day. Now I upload the code. The whole code is written i...
I've been looking at DDS recently, and a lot of information uses elliptical filters. I also want to make one to try. It seems that the requirements for elliptical filters are very high. I would like t...

With a rapidly aging population, a young couple is now required to care for an increasing number of elderly people, leading to a growing difficulty in providing care for them. E...[Details]
The Waveshare ESP32-P4-ETH is a compact ESP32-P4 development board with Ethernet and PoE support. It looks very similar to the Olimex ESP32-P4-DevKit, minus the pUEXT connector. However, we've also...[Details]
We know that the power output by the engine does not directly act on the wheels to drive the car, but needs to pass through a series of power transmission mechanisms. So how is the power transmitte...[Details]
Using an electronic load is like thinking of it as a resistor that dissipates the power supply's output. The most straightforward mode is the CR constant resistance mode. In this mode, by setting a...[Details]
Most electric vehicles currently lack a gearbox, only a single-speed reduction gearbox. This includes Teslas, but that doesn't mean electric vehicles don't need a gearbox. Thanks to the constant to...[Details]
The term "remote meter reading" literally emphasizes remoteness. But how far is remote? One kilometer? Two kilometers? Those aren't considered far at all. Currently, the longest distance for ...[Details]
Abstract: This design uses field-effect transistors to create a tube-like audio power amplifier. The preamplifier uses a single Class A transistor, while the power stage utilizes Class AB push-pull...[Details]
On August 14, Chinese researchers broke through the bottleneck of energy density and application performance of existing traditional lithium-ion batteries and developed soft-pack batteries with an ...[Details]
Robots need localization algorithms to determine their position. These algorithms typically work in conjunction with sensor data to calculate the robot's position. For engineers and researchers, fi...[Details]
Flashing the firmware of a fuel-powered vehicle is used to increase vehicle power, but why can't this be done on electric vehicles? The reason electric vehicles can't be flashed is to protect the v...[Details]
