If you are a hardware engineer, this is the task for you. Use your creative skill to come up with a way to program or manage any vacuum pump to have some intelligence. The vacuum pump can be programmed to pulse, meaning you can program it to increase slowly, wait for a short period, then decrease slowly, wait for a short period and then increase slowly until it reaches the highest vacuum level. Step 1: Convert any aquarium(fish tank) pump, whisper pump or refrigerator pump into a "vacuum pump". You can search for any of these on ebay or amazon. It costs anywhere between $10 to $20 USD. If needed, I can provide instructions on how to modify these pumps into a "vacuum pump". It is best to create an "add-on" device that can work with any existing vacuum pump. This way, we don't need to spend huge amount of money to manufacture the vacuum pumps from scratch. Step 2: Use whatever suitable programming language to create the below User Interface to acce...

We need a custom built electrical switchbox. We have a computer control which will control this box with 12V DC signals. This box will have two inputs: AC power and four 12V DC signals coming through an RJ45 terminal. The outputs are four pairs of switched 120V AC terminals for controlling AC appliances. The appliances do not need to have AC sockets, as they will be wired directly by hand.

Seeking an EE to be able to develop a concept for a new product: Proof of Concept development - The product will require the design of a small circuit board using commercial and readily available components to implement the functionality. Design of the low voltage (battery cell powered) circuit along with a construction of a simple breadboard will be required to display the functionality.It is anticipated this will need experience in analogue and digital (simple) circuitry to make this happen. The purpose of this development/breadboard is so our client can display and demonstrate the methods of operation to their potential investors. Ideally the implementation should be minimal and cost effective to achieve this with a quick to turn on developing the prototype/breadboard Experience required : Analog and digital simple microcontrollers and associated programming/debugging Visible LED and IR LED and detector experience Chip accelerometer and/or inertia detection

The CAT system should test the response of the following types of filtering circuits: Low-Pass and High-Pass. design low-pass and high-pass filters. along with a copy of the frequency response shown in p-spice. The Analysis routine should determine the following parameters: Maximum Gain and Frequency, Minimum Gain and Frequency, f1 or f2 values, bandwidth, and Filter Type (LP or HP). The data must have only one maximum point and if there is an f1 point or f2 point, there can be only one of each, not multiple f1 or multiple f2 points. The Analyze routine needs to include linear interpolation for finding the f1 and f2 points from the adjacent data values. need this in hour or two . this is a small project can be done within an hour google already has low and high pass .but not with two filters so lets see

We have a PCB layout job that will take an existing .pdf schematic, adjust circuit design based on red line changes (mostly deleting a few sections) and then layout a new board based on a .dxf file of the board outline that includes all critical placements. the board is approximately 4" square and will be populated with about 80 - 100 components. We will order and assemble prototype boards here in house. This job may actually be two very similar boards with the identical schematic design. We prefer the Use of Eagle as it allows the most flexibility for us.

Basic circuit to convert the voltage output from an Arduino controlled MCP4725 DAC outputting a voltage from 0-5V DC to a signal voltage of -5V DC to +5V DC. Therefore 0V = -5V, 2.5V = 0V, +5V=+5V This is for motor control so a clean signal is required and possibly a 0V start up output but this is not essential.

As you know, big box stores demand very low cost electronic gadgets. Often consumers will enjoy using an electronic gadget for a few minutes, and then will discard the gadget. Dichroic lcds require voltages > 9V. 9V driver chips are expensive, and chips suitable to drive 3V TN lcds will not handle voltages greater than 5V or 6V. I want you to write up a basic BOM. After I approve BOM, you can also make the schematic and gerbers. I need you to be creative, to "put your thinking cap on", and suggest a VERY LOW COST pcba to drive a single dichroic lcd pixel off and on, like a simple flasher circuit. The precision of the timing of the flashing off and on is not important. Square wave is best but not required. Direct drive is OK, but a multiplexing rate of 16 flashes per second or 32 flashes per second reduces battery consumption substantially. If a pcba with direct drive is lower cost than a pcba with multiplexing, I would prefer a direct drive pcba. For example, in...

This is a PCB design job. And I want you to use PADS for both schematic and layout design. The PCB is a PCIe card. I'm going to use the XR17V352 (PCIe-UART bridge) for PCIe interface. And the UART will be connected to microZED module. Simply say, This is for giving PCIe interface to microZED through UART interface. I want 2 UART connection to be connected between PCIe and microZED. I can't give you more information of XR17V352 because I couldn't find a reference schematic of it. And I want you to have some knowledge about the Zynq which is the SoC on the microZED because you need to understand it how to make the UART connection. It is basically nothing but a PCIe to UART bridge circuit attaching microZED carrier to the UART interface. So I want it cost effective, i.e. 2-layer design.

I am looking for an electrical engineer to design an electrical control box for an oven. I will need detailed specifications that I can use for taking in offers for parts and/or a fully assembled control box. Delivery is a list of components and schematics for wiring. We will only be making a few of this machine at this time, so I think it would be better to use PLC:s rather than PCB:s. The box will control one motor and two heating element arrays. The motor will need adjustable speed and soft start. The motor will also work and pause in intervals. The element arrays will be controlled individually and by a common thermostat. The elements will also be controlled with a timer. The machine will need an emergency kill-switch that turns everything(motor&elements) off Attached is a schematic representation of our system and our needs

We're are looking at building a dodecahedron speaker with integrated amplifier and noise source. The 12 identical speakers have an impedance of 8ohms each and maximum input power of 100W RMS but 20-30W per driver should suffice to achieve an overal SPL > 100dB @1m as the driver sensitivity is stated as 85dB/1W. An integrated pink or white noise source is a bonus. Space is of the essence as we want to integrate the amplifier within the dodecahedron if possible. The brief is to design and build the first and hopefully final version of this amplifier (we will build the dodec and source the required speakers).

Fido is a Belgian startup looking for a talented electronic schematic designer and PCB designer that is open to help a team design the ultimate dog wearable, to be launched this year. The PCB design should take into account multiple sensors (e.g. accelerometer, gyroscope, etc.), wireless charging and radio chipsets (e.g. BTLE, Wi-Fi, etc.). The ambition is to provide the maximum of information on an as small as possible footprint. Therefore, the PCB designer should have a firm grasp on building small and compact PCB designs. The tasks will be to: 1) Review high-level product requirements and provide feedback on feasibility to the team; 2) Support in the development of the first electronic schema's; 3) Produce and iterate on PCB designs. The ideal candidate has a startup mentality and can work under tight deadlines and often with open and changing requirements. Your own interpretation and feedback is therefore matters and will greatly impact the product design and product materia...

I have a fixed clock 32 bit Booth multiplier, which has to be converted to Variable clock Booth Multiplier. Right now it takes 32 clock cycles to output a result. When it is converted to a variable clock multiplier it should take variable number of clock cycles depending upon the type of the input.

Hi, this project is about developing 3 micro circuits (1 of them is remote controller). I need developer to make the following microcircuit: 1) Micro circuit with LED lights strip (6 LEDs) remotely turned on and freezing for 8 seconds, and then self shutting down. size: 80x30x8mm max Working Voltage - 12V max 2) Micro circuit with LED lights strip (6 LEDs) remotely turned on and freezing for 8 seconds, and then self shutting down, size: 80x30x8mm max Working Voltage - 12V max 3) Micro remote control (not IR), it is desirable to radio waves (or Bluetooth). Which will operate at a distance of 10 meters (max). The purpose of the remote control is to switch on LED lights described above. So remote control will have only 2 buttons (each button turns on each device with LED strip). size: 45x25x10mm. Working voltage - 3V max. Briefly, I need 2 separate devices, which controled by remote control (3rd device). Budget: TBD
