We need a design of the interior structure of a vibrator. According to IEC 60704, the noise level of the vibrator we want should be under 40 dbs; Portfolios involve the use of eccentric gears are not allowed, please think about other ways to design this vibrator; Since the design will be applied to vibrators(sex toys), the motor and the drive circuit should be as small as possible.

We have a file we think is in Proteus project format but we dont use this ourselves. We would like the project opening and output to either a pdf to show the schematic circuit diagram, or perhaps converted to a freeware viewer we can read. We dont know what is in the file as we don't have the software ! It might be nothing useful. No other work is required, you just need to have Proteus or something that can read the file. I will send when project awarded.

I'd like create a circuit board similar to the Sparkfun RTK2 (P/N GPS-15136) board with some circuits that I don't need removed. I attached a picture showing an RTK2 board with the pins and connectors that I don't need crossed out in yellow, and the pins and connectors that I do need circled in green. Id like to add the circuits of an HC-05 Bluetooth module to the board. I will supply the board silhouette (See attached .dxf file), you will have to make all of the components fit with-in that silhouette. The location of the power LED is critical and must stay in location shown in the attached picture. The USB-C port should be a vertical female port and should be on the side of the board opposite of the power LED. Location of the USB-C is not critical but its orientation...

...DC pumped degenerate Josephson parametric amplifier , (DCPJPA) 3 4 4 . The DCPJPA consists of a Josephson Junction in series with a DC voltage source, and LC parallel circuit coupled to a long lossless transmission line 5 . A sufficiently long transmission line acts also as an ohmic resistor with a real impedance equal to the wave impedance of the transmission line. A DC voltage applied to a Josephson junction excites in the Josephson an AC current with a frequency proporti onal to the applied Voltage ( f 0 » 483,6 GHz/mV). Applying a DC voltage corresponding to twice the r esonant frequency f r of the LC circuit allows to generate squeezed photon states at f r . The problem has to be treated quantum mechanically under quantization of the LC circuit as ...

Hello Everyone, I want to design an RF Energy harvesting circuit. Therefore, I would like to develop a simple circuit on Keysight ADS, do the simulation, and get the expected results before fabrication. If any of you could help me design the circuit with higher efficiency and dc output voltages then it would be a great help. I would be paying more than the above-mentioned price if someone could help me complete it within 2-3 days with all the requirements fulfilled. Here are the requirements for my circuit. 1. The rectifier should be of dual-band that can operate at two different frequencies of 900 MHz and 1800 MHz. 2. I will be using an antenna of 50 Ohm as an RF source. Thus, the impedance matching between the rectifier and the antenna should be...

Suppose you have a motor connected to a motor circuit breaker such as a Schneider Electric GV2ME08AP. This breaker can have add-on contacts using GVAE11 or GVAN11 extra modules, so there are some Normal Open and Normal Close contacts to work with. You have a modem-router with a sim card to provide internet access to the place of installation. An ESP32 module or a small PLC is there to connect. The end user must be able to connect from another city(!) to the ESP32 or PLC through a simple web page. The web page must me in a free web site creator such as Google Cloud or Wix web hosting. The ESP32 or PLC and the user PC are connected to a different wi-fi spot. I need to see the state of each motor even if I am in a different country! There are 15 different places, each one far along...

You need to be mathematically skilled as well as knowing how to make a video. I would like to show the difference in your electric bill where you pay for Apparent Power (S) which is a function of Active Power (P) and Reactive Power (Q), so the function is S^2=P^2 + Q^2 or then S=SQRT(P^2+Q^2) It needs to show how the electric current normally has its fluctuating voltage U (in Volt) and current I (in Ampere) oscillating in a perfect Sine-wave when you ONLY have pure resistive load (e.g. heating) but how there is a phase shift oscillating between 0-45 degrees when you have inductive loads (e.g. motors, welding, compressors, transformers etc). Since the phase shifting will be going between 0 and 45 degrees the whole time, I want to show how the electric bill is normally averaging to abo...
Hi - we have several similar pcbs that control water heaters. We have seen more failures than we would like and would like a review of whether the design looks sound and if the components are correct per the BOM. Is this something you can do. We have the BOM and Gerbers but in general not the circuit diagram. We can ship boards to you. Mike

Electronic Strobe Light Project. I have already paid a Freelancer contractor to design in KiCad a circuit and PCB layout for my project. I have all the files. The problem is that the last designer laid a track on the PCB between the SMD diode for heat disapation which wasn't needed and it make it impossible to get diodes fitted to the board with short circuiting. I have adjusted to the track layout to remove the useless track. I need someone to now look over the files and make sure everything else is still correct and source a PCB maker who can populated both the component side and diode side of the boards togther with the screen printing, cut to the correct shape and have the mounting holes. My previous designer refuses to correct her errors and so I'm re-submitti...
