I would require the PCB to be modified and it is a fairly simple job as just changing pad dimensions. I have the gerber files, BOM list, Pick and Place files and etc. I'm changing a component and hence requires this redesign. After redesign I would also need second opinion on the functionality of the device.

Stage 1: Generate a 5 kHz clock signal ? Produce the VHDL code of a clock divider that generates a 5 kHz clock signal. The module should have one input clock (system's clock) and one 1-bit output (the divided clock signal). Stage 2: Generate a PWM signal with the frequency of 5 kHz and 50% duty cycle ? Produce the VHDL code of a 5-bit counter. The module should have one clock input and one 5-bit output. (8 marks) ? Produce the VHDL code of a 5-bit comparator. The module should have two 5-bit inputs that have to be compared, and one 1-bit output (the result of the comparison). Set the comparator threshold value (the value to be compared with) at 10000 (binary). Stage 3: Generate a PWM signal with a variable duty cycle at a variable frequency set by the user. ? Reconfigure the clock divider module to support variable PWM duty cycles (25%, 50%, 75%) and variable output signal frequencies: 5 Hz, 5 kHz, 500 kHz. The user should be able to set the PWM signal in any of the above duty cycle-...

Hello, My name is Robert, I am looking for individuals or companies to help design a custom highly affordable pid temperature controller that i can take the design to a supplier to manufacture for me. We are creating our own brand essential oil vaporizer but do not like the current chinese pid controller boxes on the market our goal is to have a custom one created so we can have our chinese factories manufacture. I am ignorant to this type of product but see all kinds of items on the market like Arduino or raspberry pi and i am very interested how cheap we can make this yet have the high quality parts and programming, We need this part to help build our own enail   [obscured]  /?gws_rd=ssl#q=enail Basically all this does is fit around the diameter of a circular titanium petri dish and heat it to a stabilized desirable temperature. (sort of like a retro fitted soldering station with a lcd screen to show temperature setting and actual temperature. With the finished product hoo...

Hey - I am a toronto based independent artist and need someone to help me design some PCBs for a project I am working on. I have sample designs but want to work with someone to improve on them. From what I understand, the project would be very straight forward and not difficult for anyone with any experience/education... but I have neither. I would like to work with someone from Toronto, but am open to anyone at this time.

Ok I have in mind a device that I have a vision for. The technology, potentially, could be used for many applications. I have one idea right now that would form the basis of design. **note this product involves electronic components such as market available GPS module / antenae. I am willing to pay to get a very good product, however it will be broken into sections, each with various weighting in progress payments. Meaning, no point paying the full amount only to find it isn't feasible. So I propose the following overall breakdown : 1. Investigate Phase - Investigate the components I propose or suggest alternates, with regards to achieving the specified outcome. Investigate any patents (freedom to operate), or potential for patenting this idea. Provide feedback as to whther the idea will work from a technical standpoint, and approximate costings of components, with basic design and manufacture approach. (In a nutshell, can my vision become reality with components currently availabl...

I'm looking for a completed product that accomplishes this task: When an interior door is open = nothing. When that door is closed: a random song, (on an SD card that has multiple songs on it) plays randomly chosen song. When the door is open again: Any song playing, regardless how long it was playing, will stop instantly. This apparatus would be mounted inside the room, above the door, and simple. A basic plastic housing is needed. This should look simple and clean as its for a residential application. Features: Decent audio quality (think sound machine), Volume toggle (that stays on a chosen loudness setting), Battery operation. Parts are included in job price.

Hello, I am a mechanical engineer with several inventions. One I would like to develop comprises of electronics. Although I do have limited knowledge in this field I would rather pay someone who knows what they are doing. I would like a PCB designed and converted into Gerber files ready for prototyping. I have a list of requirements for this project but briefly outlining the PCB requirements: *miniature design *low power usage design *energy harvesting to convert movement into electricity to charge the battery *Wi-Fi to transmit data to apple/android *gyro meter to detect movement *temperature sensor *microcontroller I would also like embedded software to run the PCB once prototyped. If interested please contact me and I can provide a lot more detail and outcome desired. Cheers!

Dear freelancers, LD3320 is a speaker independent speech recognition module. It is self-enough which means that it do not require any external auxiliary Flash chip, RAM chip or AD chip. It can complete the function of speech recognition, and really provides a single chip solution for speech recognition. I would like to know is there any of you out there, who is able to communicate with the above described module using an Arduino board ? When I say "to communicate" I mean to be able to enter a new word in his dictionary as well as to be able to detect if the module recognize the word human speaks. I don't need any graphical indication, just a signal that will tell me, the word is known (in the dictionary of the modul) or unknown. Thank you very much for your effort. Sincerely, Bojan.

Attached are 5 sheets that need to be re-drawn as electrical drawings(last 2 are same page). It is important that these need to be in normal, electrical drawing format with some line straightening, and standard symbols. If this does not make sense to you, then may not be a good idea to quote. I expect a first pass, then some revisions, then a final release to call it good. Hoping to get this square, as I have another 2 other drawing sets that are larger that need the same kind of work, and success on this gives you first dibs on the next. I am looking for improvement on the sketches to get to good elec-dwg format, not simply making a cad version of the sketches. Feel free to ask Qs. I will provide a title block for use in autocad format once awarded. -Mark

I'm looking to design a prototype with electrical components These electrical components will be used for products that sell between 10$ - 70$ to consumers. So these are not big products. They are the size of regular home appliances. Some of these devices require electronics and some do not. Some are purely mechanical, or may not require electronics in the first place. I'm looking for somebody that can design a digital schematic of how everything connects, if at all possible. If digital schematic is impossible then a physical prototype will need to be made, however a digital copy would be preferred. I will reveal more once we converse a bit Looking forward to hearing from you gentlemen!

A Non Linear Resonator model has to be designed in following Steps: Step 1: Designing of existing model into Advanced Design System (ADS). Here I will send you all the details you just needed to have good skills of ADS software and then you can able to design it easily. I just needed the existing results to verify in ADS . (Will pay 20% amount) Step 2: After designing the Non linear model successfully in ADS. We can go ahead and design it using Verilog-A. Knowing the circuit designs in ADS will help plus I will also provide you the 60% codes and you just need to put all the work together and verify the results with ADS software results. (Will pay 50% amount) Step 3: Documentation with No plagiarism .(will pay rest 30% amount)

I need an electrical engineer to help me design a PCB for a strain gauge indicator. I have most of the schematic already, but will also need some help connecting the already-designed circuit to the PIC18F, so some research may be in order if you don't know how to use the PIC18F. Attached is the schematic. Hope to hear from people soon and hope to get this done as soon as possible! :) Note: I will handle all the manufacturing myself.
