I would need it to have a buck boost circuit that could do 0vdc-60vdc @5amps as well have a current limiting feature for testing equipment, etc. & perhaps digipots to control the output voltage and current limiting digitally through the menu. I also will be using a TFT LCD to display a menu & to show voltages & current draw, so using an STM32 to drive & control all the logic would be preferable. Im not sure which batteries would be best to use in this so achieve the desired power outputs that I want so perhaps you may have some suggestions for batteries but for whichever batteries it would need a BMS and all protections as well with a USB C recharging circuit for recharging it & finally a power switch...

    This project is for an Electronic Engineer and a Circuit Designer. I require speech of 8KHz sampling 8 Bit will do, for 32 messages of differing lengths. The messages will be recorded via a simple Microphone, and uploaded digitally for some pre-recorded messages. A PIC micro should be used and some easily obtainable memory to store the data should also be used. If improved quality of speech can be made by increasing sampling rate or bit count or any filters etc.. these should be considered; but must be low cost.

    ...heating control project that uses an Arduino board and a motor-controlled valve to regulate the flow of hot water from a primary circuit to a secondary circuit. The primary circuit is connected to a source of hot water (fernwärme/district heating) that maintains a temperature between 60 and 120 degrees, and a permanent pump that can not be controlled or regulated. The secondary circuit is also connected to a constant-speed pump and the goal is to maintain a temperature of about 40 degrees. I have implemented a basic control logic using switch cases and if-else statements, but I am having trouble getting the system to accurately regulate the temperature of the secondary circuit. I have read that using a PID controller can help improve the performan...

    We are looking for a long-term buyer/purchasing agent with knowledge of electronics. We make prototypes and small batches (10-500 pieces). Our devices include touch screens, single-board computers, batteries, LEDs, and small circuit boards. We are also working on smaller devices. Sometimes you will help us choose prototype parts. In this case, the price of a large batch is not very important, but how to get one or two pieces quickly and reasonably for testing. The main work is to ensure that the parts have the necessary features and that they actually work. For example, we currently need a PowerBank + trigger-USB cable that supports PD/QC fast charging, so that we can get power out of both 5V USB cables and 12V USB cables, with sufficient amperage in both. A test batch (5-20) means ...

    I need a circuit design & fabrication of a prototype unit to limit and dissipate high voltage spikes on a 600 VDC, 3.5 kW power system. A small wind turbine on my farm produces up to 3.5 kW, 600 VAC,3 phase power at wild AC frequency (0 to 200 Hz?). A full bridge, 3 phase rectifier takes the wind turbine output & generates 0 to 600 VDC, single phase, single leg, at varying amps, with some noise. If the rectifier output voltage exceeds 300, 400, or 500 VDC (switch selectable), the rectifier engages a load dump heater to dissipate excess power and control maximum voltage output. The rectifier's DC output is fed to a Morningstar Tristar MPPT Charge controller (Model: TS-MPPT-60-600V-48) so as to charge a 48 VDC battery bank. This $2,000.00 Tristar is extremely se...
