Hello, I wanted to know if you could help me. I'm designing a new product that needs an internal power generation. My research has steered me towards "disc type axial flux generators /motors". See attached sketch idea. Basically I need a test bed to prove theory I have based on the contrasts that are given. I can't fully describe the entire design but part of it needs to generate electricity and output it to a outlet, which kind of mimics a typical low voltage wall outlet performance you would find at a normal house. The initial device constraints was to have a cylinder can design with a max diameter of 3.5 -5 inches, and have the device be very light weight, and requiring very little force to spin the axial flux inside. I have not specified a height yet this is all a idea in testing phase. What I'm requesting is a design or instructions to create a test bed in my shop and so I can build and tested it, the shape and design are critical. This is a generator, I will ...

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...

Most of the time I have 120VAC available via generators. However, when the generators (which is the prime power source) run out of diesel I need at least an hour or two to continue powering my sensors and cell modem. They both require 12VDC and at full draw require 350ma. This is the peak when the cell modem is transmitting. While not transmitting the requirement is less than 100ma. So I need batter backup. Solar is another option as more and more I am going to places where the generators are only used at night (light towers). I may have to get more use out of this option at some point. Here are the general specifications: - 120VAC input - Battery backup (4x AA or equivalent) - Solar backup (12v 10W panel) - 12-15V DC output for sensors, cell modem, and 5VDC regulator - a voltage meter scaled 0-5V from 10-18V for the MCU ADC - digital output for detection of battery (HIGH on AC, LOW on Battery Backup). Please send me a quote on this project for a Schematic, BOM and general board l...

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 would like bids on designing the circuits, providing gerber files, writing code and providing a test article. This item will be FCC certified in the US and must meet all compliance requirements. This device will be based on the following CML chip while operating and approved only in the MURS bands to avoid FCC operator license requirements.   [obscured]  /products/CMX883_Baseband_Processor_for_FRS_MURS_PMR446_and_GMRS_Leisure_Radios/ I would like the bids to include the incorporation of a GPS chip with antenna and routines to locate the distance, bearing and position of another matching radio. I have identified the formula that will handle this. The screen should be four lines with OLED yellow display. There will be about 20 menu screens to set up groups, poll locations, text both ways, review old messages This will be a small qwerty keyboard similar to Blackberry. There will be no voice capability included. I need someone with strong radio design skills and a circui...

Since I'm often overloaded with work, I am looking for a work buddy. Someone I can trust, and share future projects with. I am very specifically looking for someone living in Davao Region, Mindanao, Philippines. I need to travel several times per year to Tagum City for personal reasons. It would be great to get in contact with some engineers in this area, so we can work together on projects more efficiently. These are the skills I'm looking for: - Circuit Design. You know how to desing electronic circuits (analog and digital), and have preferably some experience with a design program like Eagle, Target3001, ... (or anything similar). - Embedded Software. You know how to program a microcontroller (preferably in C). I myself have experience with 16-bit PIC microcontrollers and will soon learn how to use the Cortex M7 (from ST Microelectronics). Experience with one of these would make our cooperation easier. - IoT (Internet Of Things). For future projects, I will need to focus on micr...
