Project Specification 1 Project Overview An Electronic Speed Controller (ESC) for Vertical Take-off and Landing (VTOL) Unmanned Aerial Vehicles (UAVs), such as quadrotors and hexarotors. Contractor is ordering from Manufacturer to construct, based on Mystery ESC 40A design, similar ESC controller with improved functionality. ? Performance identical to Mystery 40A ESC. ? Data output through I2C bus is required, specifically RPM of motor, temperature and current. ? PID control of motor RPM is required, so the ESC drives motor at constant RPM through during whole mission. ? Mounting holes have to be added to the design, to attach the ESC to the airframe. ? High-end components are to be used. ? Custom firmware based on open source code ? ESC has to be able to receive commands through I2C bus 2 Project Details 2.1 Inputs/Outputs ? Input Data: PWM signal, commands from 40Hz to 1kHz ? Output Data: I2C bus (3,3V logic) ? Data inputs (PWM, I2C) have to be isolated from the battery ground (optoi...

We are looking for someone with engineering and design experience to MANUFACTURE a prototype of a self-propelling fish toy. This means we need the product to be built FROM THE GROUND up-including outer design AND PCB along with the software, algorithm, etc. We DO currently have an algorithm for the fish movement that we can provide you, but it MAY need to be modified for optimization. Additionally, we have a model and dimensions for the body that you can use to help with the design process. This prototype should be strong enough to support a triple hook attached to the belly of the fish but not so heavy that it will quickly sink. Once the prototype has been manufactured, we will then ask you to briefly record you testing the prototype in the water and then ship it to us once we deem it satisfactory.

Hello. I own a furniture company. I currently design furniture in the UK and get it made to my specification in China. Currently I create 2D drawings in CAD software (DWG format). I would like to add 3D visuals to the drawings that I provide the factory in China and also want to show my customers visuals of what the furniture will look like. For now, I would like you to give me a price for turning a DWG into a 3D visual. The DWG is of a desk that is made in wood with metal legs. This is a test and there will be lots more work but I would like you to price it normally so I understand your prices.

We need a simple PCB relay. The attached picture shows how the relay should work. The relay is quite simple. It's about the same as a laptop battery. It only does three things: 1: The system runs on the internal lithium-ion battery if the power supply is not plugged into an external 110vac/220vac power supply. 2: The system runs off the power supply if it is plugged into an external power supply. 3: The battery charger charges the battery when the battery is low and an external power source is detected. That's it. Here is a more extensive description by our electrical engineer. He has not designed a relay for power supplies before and that is why we're hiring you to do the work. His inexperience is your opportunity! "110V AC mains power is supplied to both the Meanwell power supply (which outputs 48 V DC at 4.5A) and the battery charger, which recharges a 48V DC 4.5A Li-ion battery. Both the power supply and the battery are wired to provide power to the LED, but only one sour...

Understanding the role and limitations of the RF power amplifier is very important when studying modern communications systems. This component fundamentally affects the communications quality, bandwidth, and power usage. Various of the key design choices such as modulation scheme, data coding and transmit power will be affected by the amplifier characteristics. Usually, most of the RF measurements used to characterise and understand the amplifier require the use of expensive equipment. This has often meant that practical RF systems, particularly looking at the amplifier, have been out of the reach of undergraduate and master's level students and their practical work is usually limited to software simulation. With the advent of the National Instruments Universal Software Radio Peripheral (USRP) an opportunity has offered itself to generate a low cost, semi-automated test system which can be used to observe and explore a flexible and software defined RF communications link. The ai...

Dear Interested Partner, We are looking at manufacturing powerful ASIC litecoin miners. Would like to piggyback off existing hardware technology like the 28nm Avanlon chip or Coincraft A1 chip (which are in use for Bitcoin Mining) if possible to save on new hardware design. What we are ideally after is someone to program either of the above chips to work on mining the Scrypt based cryptocurrencies like Litecoin for example. I understand that the main difficulty with this is getting access to the (litecoin) code to enable the chips to be used. I welcome your input, ideally you would have experience with ASIC machines. We have ASIC bitcoin machines here we can use to test your software with. If we need to make our own chips that may be suitable but we can discuss that.

The product design will require two PCB's to be designed which will go into two separate modules and communicate via bluetooth. The modules will be NEMA 6P and 7D compliant. The control software will need to be written for both PCB's (preference is C/C++). PCB1 will need to send / receive information with a mobile device application via wireless communication with a network router. PCB1 will need to send commands / receive commands via bluetooth to PCB2. PCB2 will need to send responses / receive commands via bluetooth to PCB1. The first PCB (PCB1) hardware design will require the use of the following components: -- Microcontroller (Atmel AVR) -- Wireless module (XBee module or approved designer's choice) -- Bluetooth module (approved designer's choice) -- Pressure transducer (analog, to be determined) -- Capacitive sensing circuit for touch (discrete circuit or IC) -- Indicating LEDs for unit activity -- Backup battery* * Backup battery should be able to power PCB 1 for a ...

Need to design this rack gear mock up designed with AutoDesk Inventor 2014. I need the rack gear and pinion gear design properly especially the gear profile. I generated the pinion gear with software but the line needs closed up, which takes too much time. Neither the rack gear profile is right. Can you have better way to fast the process for me. There is no need to have consideration of element strength test, the component is for demonstration only. Pinion gear diameter is ok for me. You only need to keep the rack gear as it is except the gear profile. Fixed price of $50.
