I am building a new house in Florida, which requires the following engineering: 1. Electrical Engineering (riser diagram and load calcultions) 2. HVAC engineering - Energy Calculation (I already have someone working on the plumbing engineering, but would be willing to have this as part of a package, if it makes sense.) House Description: 1. 3 bedroom, 3 full baths located in both the single-level main living area (1500 square feet) and "casita" in the back (two-story living area of 863 sq. feet). Detached 500 square foot garage. (See attached image). Description of Work: I need for you to design both the required electrical engineering and HVAC engineering to the specifications of Collier County, Florida for building permit submission. For questions regarding exact specifications, please see:   [obscured]  /index.aspx?page=176 Optimally, you would provide the stamped plans. However, I would be willing to accept the plans and have them stamped locally. ...

We have a series of circuit diagrams and an image of a PCB layout from which we need to produce manufacturing files and a BOM. We are aware that at least four components are obsolete, and suitable replacements must be found. This is a time-sensitive project. We have included the image of the board layout (two-sided), and an example of one of the four circuit diagrams with component values shown.

Hello, I need a pcb layout design for demo board just like the Microchip DM160219 demo board using sensor MTCH6102 - the only two differences are: - different layout for the "touch" area - entire circuit should be on the back of the PCB (they use 2 layers however the back is ground so if circuit is to be designed on the back layer, the Ground needs to be in the center) - if not possible - we need to have breakout board for the circuit as I need the entire area to be the touch. Capacitive Touch Sensor that is using regular copper pcb layout for the sensor pads. If you go on   [obscured]  /DevelopmentTools/ProductDetails.aspx?PartNO=dm160219 you can find documentation files on their board. I need the board to be at size: 33mm by 66mm if you read section 6.0 (page 10) of:   [obscured]  /downloads/en/DeviceDoc/40001750A.pdf it will explain on constraints of the design.

I need the schematics drawn for me so that I can order some PCB. i need the board to include a 5v lithium ion battery charger which i will be connecting leads to and attaching to a mini usb jack. The board will also need a bluetooth transceiver as well as an amplifier in the 6w-10w range. Either with one channel that is 6-10W or two channels that are 3w-5w each. The board will be used to connect to through bluetooth to a phone or computer and then play music through the speaker connected to the included amp, and all run off of the 3.7v-5v lithium ion battery. I AM ONLY LOOKING FOR THE SCHEMATICS NOT BOARD PRODUCTION. I will use these schematics to submit and order PCB's that are as small as possible and include all desired features.

Hi People, I would like to obtain a quote to design and produce a 220-240VAC 50Hz to 115V AC 60Hz Pure Sine Wave Converter to suit a 15 watt electric motor. The device needs to withstand a Start current of 7 x FLC and have a duty cycle of 20 minutes on/10 minutes off. The device needs to plug into an Australian Power outlet via a flex lead and be equipped with a US plug to accept a US product plug. I would need the design, initially as a prototype in a test box. The design must then be able to go into production in a compact Moulded Plastic case. The case can be an "Off the Shelf" box if it looks professional. The design will need to meet all Australian and NZ standards including AU/NZ Approvals (RCM Electrical safety Mark, A-Tick, C-Tick, MEPS

THE PROBLEM: UL requires us to have a custom cable design for our 42 volt lighting system. The cable needs four 12 AWG wires (not three. We need a fourth lane of power that allows a PCB to detect the microvoltage fluctuations in our device.) The cable must have a custom interface so no existing cables can accidentally be plugged into our system. THE PROJECT: We need to hire an ME or EE with wire harness or cable design experience to create a custom cable (male to male), socket (female only) and adapter (male to male & female to female). The cable will be sold in 10 foot, 20 foot and 30 foot lengths. REQUIREMENTS: - Deliver SolidWorks 2014 files. - Proven expertise with wire harnesses or cable design. - Speak fluent English. Not broken English. Not Google Translated English. True, fluent English skills. - 4.5 star rating or higher with a minimum of 5 completed projects. - Portfolio pieces that convince us you know how to design a cable. We have seasoned mechanical engineers on s...

I have a programmable infrared TV remote control that that I need to clone the PCB. I'm needing the full schematic, Gerber files and other necessary files to recreate this board. This remote control uses a removable but programmable micro-controller. It's a PIC16F648A that sits inside of a socket (16F648). It contains two Infrared LEDs, a 9A104G resistor, a 10v capacitor, 4.000MHz Crystal and several very tiny resistors on the other side. This remote is powered by 4 AAA batteries. This PCB board is about 2" wide and about 8" long. Also a primer on the circuit and how it works would be great! Also, I have pictures of the PCB that I can provide.

Basically needing an encryption module to use a key to encrypt a set of operating messages/API into encrypted messages, then after passing through it, it is decrypted using a key, and used by a secondary processes or devices to execute instructions or messages/data. This is to protect the data from one device, that docks onto another station for data retrieval etc. So basically, encoding messages or information in such a way that only authorized parties (docking stations and perhaps a reader) can read it.
