Please take a look at this following project we have going on and let me know if you are interested in helping out. Price is negotiable, time has to be within 30 days. We have the majority of the components (listed below) and the general structure of the program here. We are looking for an indivisual with good Arduino programming and device building experience The functionality: - Arduino based device turns on. - Picture appear on display for 5 seconds, then moves to next picture (7 pictures total) - User presses button when he pleases - Depending on current picture being displayed on screen, a verbal message or mp3 song is output through 2 speakers. - Pictures keep scrolling forward and cycling after 7th pic. - 7th pic is the only picture associated as a mp3 song, the other 6 are verbal messages. - Device will be powered by rechargeable battery with voltage converters to power the components -Pictures and music are stored on micro SD card -Any of you recommendations! The device th...

If you are a hardware engineer, this is the task for you. Use your creative skill to come up with a way to program or manage any vacuum pump to have some intelligence. The vacuum pump can be programmed to pulse, meaning you can program it to increase slowly, wait for a short period, then decrease slowly, wait for a short period and then increase slowly until it reaches the highest vacuum level. Step 1: Convert any aquarium(fish tank) pump, whisper pump or refrigerator pump into a "vacuum pump". You can search for any of these on ebay or amazon. It costs anywhere between $10 to $20 USD. If needed, I can provide instructions on how to modify these pumps into a "vacuum pump". It is best to create an "add-on" device that can work with any existing vacuum pump. This way, we don't need to spend huge amount of money to manufacture the vacuum pumps from scratch. Step 2: Use whatever suitable programming language to create the below User Interface to acce...

We need a custom built electrical switchbox. We have a computer control which will control this box with 12V DC signals. This box will have two inputs: AC power and four 12V DC signals coming through an RJ45 terminal. The outputs are four pairs of switched 120V AC terminals for controlling AC appliances. The appliances do not need to have AC sockets, as they will be wired directly by hand.

Investigation of ground based absorption heat pump for space heating and hot water production system Background Heat pumps can utilize low-grade energy sources, like waste heat from process industries and low temperature heat from ground for heating of building spaces and hot water production. It is believed that absorption heat pumps consume less energy than the conventional electric driven heat pumps and the student will investigate this based on ground source heat pump. this work involves more thermodynamic work and an Engineering Equation Solver (EES) software will be used. The projectwork include the following tasks: 1. Design mathematical models for compression and absorption heat pump cycles. 2. Investigate different possible working fluids, including, ammonia/water mixture. 3. Identify the influence of thermodynamics parameters for high performance of the

Seeking an EE to be able to develop a concept for a new product: Proof of Concept development - The product will require the design of a small circuit board using commercial and readily available components to implement the functionality. Design of the low voltage (battery cell powered) circuit along with a construction of a simple breadboard will be required to display the functionality.It is anticipated this will need experience in analogue and digital (simple) circuitry to make this happen. The purpose of this development/breadboard is so our client can display and demonstrate the methods of operation to their potential investors. Ideally the implementation should be minimal and cost effective to achieve this with a quick to turn on developing the prototype/breadboard Experience required : Analog and digital simple microcontrollers and associated programming/debugging Visible LED and IR LED and detector experience Chip accelerometer and/or inertia detection

hello, i have a plan of a small apartment (40m2) and want someone who can: - design some sketches/layout of furniture so that i can get some ideas for a good way to lay out things. - as well as electricity/switches layout - kitchen, bathroom and space for 2 beds is needed. the site plan is attached and would require the source of the design you make as well as alterations to what you do if needed. note: this is a simple job, kind of a test. after this and if you do a great job we have one which include 3 villas with swimming pools etc.

The CAT system should test the response of the following types of filtering circuits: Low-Pass and High-Pass. design low-pass and high-pass filters. along with a copy of the frequency response shown in p-spice. The Analysis routine should determine the following parameters: Maximum Gain and Frequency, Minimum Gain and Frequency, f1 or f2 values, bandwidth, and Filter Type (LP or HP). The data must have only one maximum point and if there is an f1 point or f2 point, there can be only one of each, not multiple f1 or multiple f2 points. The Analyze routine needs to include linear interpolation for finding the f1 and f2 points from the adjacent data values. need this in hour or two . this is a small project can be done within an hour google already has low and high pass .but not with two filters so lets see

We have a PCB layout job that will take an existing .pdf schematic, adjust circuit design based on red line changes (mostly deleting a few sections) and then layout a new board based on a .dxf file of the board outline that includes all critical placements. the board is approximately 4" square and will be populated with about 80 - 100 components. We will order and assemble prototype boards here in house. This job may actually be two very similar boards with the identical schematic design. We prefer the Use of Eagle as it allows the most flexibility for us.
