It should be portable (running on battery) and should have an auto-cut option once the temperature reaches desired value a small motor for stirring the water. None of the mechanical components fall under this scope. Just need off-shelf components to design a circuit.
AMPUSHER . Its Home Flex 50-amp smart charger is similar in operation to its public chargers so there is no learning curve. It can be hardwired into a 240-volt circuit (typically the home’s drier circuit) or an existing 240-volt outlet. The 23-foot cable allows for more installation locations in your garage and the whole charging unit has a sleek design Sometimes you don’t need smart-charging capabilities. Instead, you might need a durable outdoor charger that can withstand tough weather conditions. AMPUSHER is ideal for home EV charging, as well as electric lawn/farm equipment, which is a growing market. There’s no app to this one, just a rugged 40-amp charger. This unit can be hardwired or plugged into an existing 240-volt outlet and the power outpu...

The preliminar idea of the project is to buid a device based on a STM32, that controls a 4 inch LCD screen with RGB interface, with 2 to 4 serial data signals and 4 to 8 buttons. Design using easyEDA and prototypes made by jlcpcb. All this can be modified by designer advice. The work is design and test of the PCB. More details: - The work is to design PCB and schematic - The circuit has a 12V power source - The LCD is not deciced, but has to be high bright, problably RGB888, to be decided - The serial data bus is CAN - The LCD probably has a backlight power voltage of about 15v - I decided to use easyEDA because I know it, but also to be decided - I decided to use STM32 because it has support for CAN bus and RGB888, but again to be decided Regards

Attached schematic shows one circuit of 4 identical circuits connected end on end. Not shown is a single opamp buffer with 220R resistor and 2.2uF film cap on the output. The power bus is +/- 15v with ground. There are no pots on the board; wires will be soldered into three adjacent holes for the Boost/Cut pot--same goes for all external connections. The Q, and the a and b Freq pots, with be replaced with 2 RN 55 resistors connected in series to the wiper terminal from terminals 1 and 3. Not shown are 4 - 10uF electrolytic caps on the power bus near each circuit with 2.54mm centers. All of the resistors are Vishay RN 55, except the two 5.1k at the bottom which are RN 60. The 10uF caps are small bi-polar with 2.54mm centers. The rest of the caps are film with 5.08mm center...

A) Design of high performance signed 2’s complement 4-bit adder circuit using carry Look Ahead Adders. (See and ) In carry look ahead adders, the carry propagation time is much less than RCA (ripple carry adder). Therefore, the addition process is very fast. As you get more familiar with CLA concept you will understand why we need it for faster adder hardware. Study the ripple carry adder first to appreciate the objectives. You may use transmission gates, static or dynamic CMOS design. 1) Draw a transistor level schematic of the 4-bit CLA in Electric and simulate it in LTSpice. 2) Draw stick diagrams and Euler’s paths where appropriate to design. 3) Perform the Electric Layout with IRSIM. 4) Verify your design by
