We are looking for an experienced Electrical Engineer with knowledge of food/automation equipment to help validate heater circuit conversion for the Australian market. We make food forming equipment for the US market. Our specifications use 240VAC, 3-phase, 60 Hz to power to energize a hydraulic ram (motor) and to supply single phase voltage directly to the heaters in our forming dies. We also transform the 240VAC to 120VAC for control circuitry. The available power in Australia is 415VAC, 3-phase, 50 Hz. We have swapped motor components to accommodate, and our controls transformer can convert this power to 120VAC. However, we need to validate our design ideas for our forming die heaters is appropriate, a special challenge given current supply constraints are limiting certain options...
I coordinate a design team for the realization of a device that includes an RF section but in the group we have limited knowledge of RF design. In particular I need to make a Class E RF amplifier with the following characteristics: • operating frequency 406.0 MHz • power 5W (37dBm) • TX duty cycle 10ms (transmission time 500 ms every 50 s) • 7.2Vdc power supply • input power 100mW (20dBm) • two-phase modulated input signal • input impedance 50Ω • output impedance 50Ω • efficiency ≥ 70% • operating temperature between -20 and +55 • the output power must go from 10% to 90% of the max power in less than 5ms • must work with VSWR between 1: 1 and 3: 1 • must not be damaged if the load is shorted or open • mus...
I am designing a connector board. Looking for schematic capture engineer for the same. It takes hardly 2 hours.
Help us with ongoing projects around power quality. We will supply data from our analysers but we need an engineer that understands all levels of power quality to interpret the data and generate a 20-30 graphic and written report. Each report will highlight any areas of improvements in areas such as power factor and harmonic mitigation.
Microprocessor 8086 with basic interfaces Bus SRAM and EPROM 1. Complete the necessary interface signals between microprocessor 8086 and SRAM and EPROM 2. The EPROM is only available in 8KB component 3. Use whatever necessary components; such as buffers, bidirectional buffers, latches, decodes, and 2-input NAND gates 4. Draw clearly all connections and components by using the emulator8086 in the lab 5. Check the design by doing the following code: 1- Program EPROM1 with all 1’s 2- Program EPROM2 with all 2’s 3- Read data from EPROM1 and add value 2 4- Read data from EPROM2 and add value 6 5- Store the modified data from EPROM1 into ODD SRAM 6- Store the modified data from EPROM2 into EVEN SRAM 7- Read data in 16-bit from SRAM at Address FAB02 and store it in AX register 8- Sho...
the concept, design methodology, architecture, circuit gate & performance (speed), and fabrication techniques for integrated circuits (ICs). The main focus is on design for complementary metal-oxide-semiconductor (CMOS) technology.
Digital Logic Design Project The project starting by pressing the pushbutton switch. The pushbutton starting the counter ( the counter for 4 decimal) such as 4265 When the number reach to the first 4 decimal digit going appear in the seven segment Repeat the process for remaining students
Using Altium designer, Design a simple PCB to be able to connect an oscilloscope to a high voltage cables with protections see drawing. Voltage: Phase to phase RMS voltage is 750VAC at 50 to 70Hz or 1200VDC depending on the device where we will connect. Transient at in the 3kV range, with 1MHz frequency. This is what we want to record. So each trace will need to be spaced accordingly. Current: The wire we will use is a AWG18, however we can have fuse holder with fuse down to 2A for the track width. The probe I’m using have only micro-grabber tip, so ideally I would like to connect on some kind of test point, as shown below. So in the drawing in attachment, the plan was to install the PCB board inside a plastic box, have my cable that are connected on the top. I was thinking of...
I have a Project at hand which requires a BLDC motor to be RPM controlled. Basically, the shaft has to rotate at a constant RPM with varying loads. I’ll give more details to the selected freelancer. So basically, the tasks to be done are: 1. Selection of Motor from online websites based on my requirements. 2. Selection of Motor controller from online websites or design one. 3. Design/coding of a Arduino based PID controller or be combined with the motor controller. 4. An AC to DC circuit design for powering the motor or selecting some readymade stuff. I am not an Electrical Engineer so I might not be able to give much technical details.
I need a multisim opamp design project. I think a good analog designed can design run, and write his calculations and a summary in 3 or 4 hours it is not a challanging task for an experiened. My budget is 100usd. I am looking for this can be done in just after you get the project. My schedule is tight. Send message for the details.
The project is to add the circuit into existing PCB. The circuit is offered. The designer will update the schematic and PCB. And if you know about firmware development for ATXMEGA128AiU and Atmel studio 7, it is preferred.
In the ppt file, you may see 4 thin wires at the pipe output. The wires can not be pulled out anymore. I want them to be connected to 4 pins head socket (green circle below) via wires on the right. The tricky thing is to solder 4 wires to 4 wires. The wires are insulated outside currently and should not be electrically connected with each others.
Circuit schematic is required for dc supply as per below information Input voltage 24v dc Output 1 -> ±5v (for in-amp and ADC) Output 2 -> +5v ( for microcontroller) Output 3 -> +10v ( for h bridge and dc motor) Output 4 -> +3.3v ( for ADC digital part) Required is that motor operation should not influence the ADC reading Find the schematic attached
Hi, Looking for an expert to design a 4-layer PCB. Below some PCB background on the expertise requested: * 4 layer PCB * Size 100x50(mm) * <100 components * Critical components for design: ** GNSS + antenna, ** NB-IoT and ** 2x SMPS buck-boost convertor * PCB design preferably to be done in Diptrace. Look forward hearing from you (expected time and hourly rate or fixed price). Kind Regards, Jeroen
Hi, I would like to install PV system with the battery storage. My power usage is quite high, so would like the system with the strongest possible panels, on the budget. Have two sunlight tunnels on the top roof which will limit panels space. Lower part of the roof is shaded, so would ideally need micro-inverters on that part. Not sure if is possible combination of micro-inverters and string inverter, maybe with optimizers?
I am after a soft latching circuit to control a 24v power supply. Using a piezo touch switch. The motor can draw up to 120 amps. I would also like it to have some inrush control to stop any sparking if using relay. Would like Berber files so can get pcb made.
