Hi, I need a high voltage circuit designed. I need to be able to transform a low voltage (ideally between 12-24V) to a very high voltage of 45,000V, so there is a potential difference between two electrodes of 45,000V (i can then vary the electrode size, distance to create the desired electric field strength etc). The output voltage needs to be variable to a minimum of the low input voltage and to a maximum of 45,000V.

I have a wireless flash trigger transmitter and a receiver. They work with a Amiccom A7105 chip. I want to develop something similar with an Atmel microcontroller and this Amiccom chip. I'm a electronic engineer and I need support for this project. I DO NOT need someone who writes all the code or design all the schematic, I NEED someone who can explain me some points : 1) I need to know how my trigger transmitter and receiver works(probably we need read the signals transmitted and received) (1-2 hours) 2) If they work with RF I need a quickly introduction on RF and protocol as ZigBee (1hours) 3) I need support to develop the library(SPI) to comunicate between microcontroller and A7105. (around 10 hours or less) I prefer working face to face so I prefer someone from UK / Italy or Europe.

We need you to convert the attached Eagle Files to Altium. The PCB is a simple open source board created by SparkFun. In addition we need you to: 1: Use our own custom silkscreen art and place it into the final file. 2: Add .5" to each end of the board and add four through-holes in these areas, so we can physically mount the board with fasteners. 3: Change the solder mask to black. 4: Radius the corners 1-2mm. 5: Deliver to us a full Altium package, including BOM, 3D renders (top, bottom & perspective views), and output a SW2014 or equivalent CAD file so we can import it into our product's master CAD file. Do not alter the actual electrical engineering in any way. This is a simple file conversion job.

Temperature control utilizing a 1000 ohm RTD input designed to output to a 3-32vdc solid state relay. The temperature control features power saving functions such as standby (reduced heat) and sleep (self power off) modes, a remote encoder / pot w/ momentary for user input, LED display and other calibration parameters. There should be an output to power (activate) other or additional modules and sleep mode may be inhibited by an external feedback from such other modules. Of particular interest is temperature calibration and related duty cycle settings as described later.

Need a talented engineer with demonstrable portfolio of work to help assess a product I have in mind. It incorporates Bluetooth low energy and another communication circuit that relies on the BLE. At this stage all I require is a very simple 'study' on whether the concept can work. From there happy to discuss moving into potential design phase. We can discuss more clearly deliverables when you apply.

I'm looking to have 3 different small boards laid out so they can be printed / assembled, and later mass produced. I have most the details, and they are small and simple boards (capacitive touch chips that run LEDs) approximately 10-30 components. Will need a little help revers engineering a board I already have. Thanks, Mark Johnson

I have an Autometer Speedometer that puts out a square wave at 5 volts DC. The faster the speed, the higher the hertz. I need a circuit that will trigger at 175 hertz and above and turn off below 175 hertz. It has to be powered by a 12 volt DC source. Would prefer if possible that the hertz setting can be made variable. I need it to put out a negitive trigger for a relay.

I have an audio source (portable cd player) connected to an amplifier through the AUX In. At the push of a button (preferably wireless) I need to have a device interrupt the current audio source by lowering its volume and instead feed a pre-recorded message to the AUX In to be played on the Receiver. The message is no longer than 30 seconds. This is similar to PA systems where when the announcers starts to talk the music is lowered. These are my constraint: 1. The solution has to be an existing device (or multiple devices) that integrates with my current setup. No computer solution. 2. I need to be able to easily record a new announcement on the device. 3. The cost should be less than $200.

We are looking for a partner who could help us to develop an IOT box which will contain up to 48 home keys. The box should be able to be opened via password provided though the app which we are building already. The Box will have a safe type pin code lock and the password will be provided via the app. Once the user input the passcode, then the door of the box and lock of the specific key will be opened. The box will be powered via ac adapter and wifi/lan cable should be available. The box size should be under 50cm high, 30cm wide and 10cm deep. The box material can be anything light weight but need to have strength that normal human can not penetrate with bare hand. The box must have water proof version and non water proof version. Below is a spec which we assume. Bluetooth Option Spec: - 5V Power supply for controller - 24V Power supply for lock device - Microcontroller module 400Mhz - Bluetooth 3.0 module - Relay switch - Electric door lock device - Developed firmware - 9-...

I have a Bluetooth Low-Energy beacon project that is based on a CSR1010. I have the beacon code working but the beacon function is currently broadcast (transmit) only. Now I need to add the ability to detect (receive) when another paired beacon comes into range. When another beacon comes into range it will trigger a PIO output. Need someone with lots of experience programming CSR BLE chips.

Hi there, I'd like someone to build a 12v circuit for me that provides a 60hz sinewave oscillator. We'll later take this sinewave oscillator and use some MOSFET transistors to amplify the signals. We'll then connect a transformer to create a 12v-to-120v inverter capable of 5000 watts. The power source of the inverter will be a 12VDC deep cycle battery rated at 110ah @ 20 hours. The battery will also be connected to an alternator providing 100 amps at 14.3 VDC. If you can build the oscillator, that's all we need for now - but if you think you can build the whole project, then great - please indicate that in your proposal. I look forward to your proposal! Please include the word "inverter" in your proposal so that I know you read this project description. Here's some reference material:   [obscured]  /watch?v=VDi_uFSr3w0   [obscured]  /wp/?p=415 I'd like the inverter to be as close to pure sinewave as possible, but that objective will be limit...

I need you to make me a circuit (tangible, not just diagram) that will connect between 2 of my solar batteries (12 V). When the first one dies, I need it to switch to the other (backup) battery automatically and keep them relayed / connected so that the solar panel will begin recharging the first one (that died). Please let me know any info you need and how much you will make me this circuit for. May need 2-3 of these circuits, so please quote me per circuit made. Thanks so much!!
