Dear Elancers, I'm was looking for buying a Honeywell resistor board (Honeywell-221508A) but unfortunately I couldn't find it and it's out of stock in most market areas. So I decided to make it by my self which I think it's not very complicated. It's just an analog card with mosfet. I'm looking for someone who help me for building this resistor board and give me some advice for the board. Please pay attention that I only need your advice and help for this so it's not a hard job. in the attachment you will find the pic of the board. Looking forward to hearing from you, Thanks,

I need developed complete electronics (populated PCB) as described here:   [obscured]  /controller/ Long term production will be required and I will need a cost per unit/ in volume of 5-10 units but production is NOT a part of this platform. Just the development which includes the design and working test unit. I'll need all paperwork associated with the design. Each time we re-designed we improved the end product substantially. That is why I am making this query. This will be our last improvement (I said that before) so it needs to be done correctly. Note: I have several versions in the worldwide market since 2008 so I know EXACTLY what my costs are. Any/all bullshit will be ignored. I wasn't born last night. Note: This is high school 101 electronics, very simple, uncomplicated. Note: I do NOT want to hear about your qualifications, your team, blah, blah, blah. Either you contact me to get to work or leave me alone! Note: If you have responded previously, you...

I need to make a prototype of an earpiece-like device that can receive transmission of soundwaves from underwater. I am thinking of using bluetooth, but I am not sure if it works underwater. I was also thinking of using radio transmission, but I would like you expertise on which option, or if there are any other options, would be best. .

Atmel IDE Design Platform ARM Cortex Processor Processor: ATSAMD20J18A This is a two part device where the devices control and communicate with each other over a bluetooth interface. Person should be familiar with: Embedded microcontroller coding, C, C++ Embedded System Development Basic Understanding of Electronics (No hardware design required.) Atmel Studio IDE Atmel ASF Controlling a Bluetooth Interface (HC-05) by a UART port with AT commands. Controlling remote devices on PCB through an I2C interface. Some capability speaking and writing English to document and comment code. Comment: Do not need HW design skills. That is nice to have but not necessary. I am an EE with a lot of design experience. PCB's have been finalized and are now in board layout, so the intention here is to get started on the code while the boards are getting laid out and fabricated. More details on the project will be given to people so a better time and cost estimate can be made. Prototype versions...

I am looking for someone to produce code for a microcontroller which is to act as a node in a wireless mesh network. The network will be used only for the streaming of low quality audio of approximately 16kbps. The node would need to decode the incoming audio stream (opus codec) based upon a channel selection by the user. The preferred microcontroller would be the STM32F4129 or equivalent as the node would also have a touch screen interface. Programming of the HMI would be a separately costed job. No preferred RF chip has been selected yet. Further details are available on request.

I am looking fro someone to design and program an HMI for a wireless mesh network node. The node will have a 2.4" touch screen with an SPI interface. The user will be able to select either one of two fixed channels (Channel 1 and Channel 2) or a third 'Home' Channel which would be selected by the user from a list of available channels. The menu structure is envisiged to be something like as follows: Page 1: Button to Select either Channel 1, 2 or Home Channel. Page 2 (or popup): Ability to set a channel as the home channel or select a fourth channel for listening. Menu structure as: Menu Level 1 (Nine options) - Menu Level 2 (Max 50 options) - Menu Level 3 (Max 20 options) The names for each Menu level or Channel would need to be editable and updatable by a remote connection so this needs to be borne in mind when programming. The graphics do not need to be fancy and a simple, clean, user-friendly interface is preferred. The processor would need to be an Arm Corte...

I need an electrical engineer to help me design a small ultrabright LED prototype product for my clothing line. I have 3D renders completed and a basic idea of what I want in the electrical platform. Although, I do need the entire interior electrical platform built for this product. I am hoping to get the prototype built and a small product run completed at least 12 working units. This is a pretty simple design and functionality. I am also looking to have this completed in the $1000-$2000 range. I look forward to hearing back from you all.

It is a multi-functional battery charging controller. I'm using MSP430F2274. You'll use Code Composer Studio. Perhaps you may use Grace or any other io configuration tool or libraries. You'll develop a program running on the MSP430F2274 with the feature as : 1) 3.5 digit LCD and 8 LED control with 5 74HC595 serial shift registers. 2) ADC control to read voltage and current of the charge/discharge. 3) On/off control of charger, load switch, etc. 4) Timing control using timers. Perhaps you'll control an RTC device. 5) Uart communication channel to receive command and to transmit the status value with regular interval.

I am looking for someone that is knowledgeable about the USB and Ethernet Phy so that they can help develop a product. Ideal microcontroller would be the Atmel AT32UC3C series. I suspect it should be capable of doing the job. I will work with you to do the schematic and board layout from my side. I will need you to write the code to program the AT32UC3C and send to me so I can program on my side using the Atmel Studio. Essentially the unit is to pass data between the two interfaces without data loss. Meeting an Ethernet speed of >10Mbps is strongly required. Only those that know what they are doing should apply. I am very knowledgeable in this area. I just do not have the software experience to make this part happen.

Hello, I am looking for some who can create a functional prototype of a Micro Headphone DAC/Amplifier for Iphone and android mobile ''samsung''. The DAC/Amplifier should be based on the AKM 4430 Audio DAC Chip. The DAC/Amplifier will not use a battery but will rather be powered by mobile device that it is connected to. The device should use official Iphone Lighting cable and Micro usb for the android/samsung mobile. The Purpose of the Device is to offer those who listen to music on their mobile devices a great HD Studio quality sound in a small well design compact and portable package. Please don't hesitate to ask any question. Design and dimensions for the prototype will be provided on request. Budget is negotiable so please don't be put off by it.

Hitting the golf ball on the 'sweet spot' of the club gives a player the maximum benefit of a proper swing. We need engineer's to help us build a club that will, on impact with the golf ball, identify on a smart phone or on the club it self, where the club struck the ball (position). Some of possible sensors that could be used are vibration sensors, pressure sensors and then triangulate the point of impact and display that on a smart phone (via BT) or on the shaft of the club with some LED indicators. Any freelancer selected, will be required to sign a NDA and provide references for their past projects.

I have created a prototype of a web-connected bulb using a Raspberry Pi micro-controller which connects to WiFi, a PowerSSR Tail that is controlled by the GPIO of the Raspberry Pi (  [obscured]  /pages/powerssrtail.aspx), and a standard light fixture. I would now like to move my design forward, in order to produce several dozen units. I would like to miniaturize my design into a compact and easily-produceable design. I do not know exactly what shape the design should take, so I am open to suggestions, whether it be soldered components or a complete PCB. The design will need to split mains power from a standard plug into three 'paths': one to the micro-controller at the appropriate rate, one to the SSR without any rating-change, and one to a powered speaker, again at the appropriate level. I will need help selecting and sourcing components as well. Inquire for more information!
