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 are in the process of re-branding and will be doing a complete overhaul of our existing website,   [obscured]   We have developers working on the design but we need someone to write the content. We do not want to re-use the existing content but this can be used as a starting point. Topics will be similar to those already included, with more to be added. Video scripts to correspond with some pages will also be required, with keypoints to be advised. The style of all content should be highly professional and reflect our company's position as a market leader. Advanced English is required for this content. Excellent spelling and grammar is essential, and all copy will need to be written from third-person perspective. Fire and electrical jargon will need to be included so a basic understanding of these, or willingness to learn would be great. Our team of experts are available to assist you to better understand these in order to communicate these effectively in our copy. Se...

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.

I am looking to create a frisbee for a new game i have invented. The frisbee needs to be approx 175g including the electronic timing device. What i hope to achieve is a frisbee that when thrown is just a normal frisbee, but when caught it activates a variable timer 2/3/4/5 sec. The timer then activates LED's to flash if the frisby is not spinning before the time has lapsed. The electronics need to be moulded within the plastic with access to the battery and the switch for on/off and varying the timer needs to be accessible. Finally the unit needs to be waterproof, sand proof etc. As this will predominantly be a beach game.

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 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.
