Assistance needed in porting code written for a PIC18F26K to a more modern model (that is in stock). Program is about 400 lines of C, I suspect the model number may need to be changed and a few pins remapped, but otherwise the code is usable. Currently using 1 A/D, TX/RX for serial and 4 GPIO pins. The code is doing battery management. If it is less time the code could be ported to Atmel or Arduino if decided, it is not doing a whole lot. Bonus points if you are familiar with Raspberry Pi. This project sends data via serial to the Pi and that also needs some updates. Can discuss that further after this is completed.

I need a CAD engineer, who is able to draw technical 2D and 3D engineering drawings of battery pack box in solidworks or AutoCAD. He should be able to make a clean 3D model of the product.

Hello, I am looking for help to create an electronic device to change the colour of LEDs based on the price change of specific stocks (list in excel attached). This has to work automatically via wifi and with a rechargeable battery. It will be similar to this project, but with LEDs instead of epaper The logic of the programming should be to check the price change % difference every 30 minutes relative to the "previous close" price. More details are in the excel file. There are 10 stocks in total, so will need this to work for 10 separate LEDs at the same time. I would like to use RBGW LEDs, individually addressable, each with a wire that is about 12 inches long. I don't have experience with electronics, so I look to you for advice on which

create a Simulink were Grid and solar energy connected the grid has its own energy which is distributed to normal household if someone installs solar energy and through this, they generate some amount of energy(stored in the battery) which is enough for 40 to 50 houses but they feed only 10 to 15 houses so this excess amount of energy transfers to the grid. the energy of solar cells may vary from temperature to temperature. solar cells generate the maximum amount of energy with the help of MPPT here we also compare with the use of MPPT and without the use of MPPT.

The client is an international Oil & Gas company who operate an existing oil and gas lease. Their name is ECU Energy. The opportunity is for the production and sale of Liquefied Natural Gas LNG (methane) and CO2 . The Field Development Plan indicates the field can produce 150 million standard cubic feet/day of Raw Gas from subsea wells. The client has defined the battery limit as downstream of the pipeline’s emergency shutdown valve (ESDV). The plant location is in the Mediterranean region The design life is 15 years. The anticipated production profile is 7 years on plateau of 150 mmscf/d of raw-gas and then a linear decline to 50 mmscf/d by the end of year 15.

For an electric automotive project Battery BMS is sending the SOC data over CAN. We are having hard time reading the data at the Cypress controller to use it to perform controlling actions. We need help in performing this.

The aim of the project is the DESIGN and REALIZATION of a technological solution for the identification and localization of lost objects via small (a few centimetre squares) and flexible tags. These tags might include a small battery, but it should not limit their flexibility and compact size. These tags should also be flexible enough to be applied on bent surfaces and be detectable at a maximum distance of 10 meters from the identification device. The considered device should use radiofrequency waves, such as Beacons Bluetooth, WiFi, and other technologies to perform the task of object localization and identification. Furthermore, this device should also be able to harvest a minimum quantity of energy from indoor sources. We are interested in the PRODUCTION of 10 items of these t...

I am looking for a design for a battery operated light that is activated if a ball hits a strike plate using readily available materials. The strike plate would be a round cylinder 108mm in diameter and 20mm wide +/- (Flexible) The ball striking plate is 95mm in diameter. The light would be at the end of a 1m pole. The light would need to time out in 10 sec or so which should be adjustable somehow if possible. The batteries and other electronic components would be housed inside the 108mm cylinder that is 100mm tall.

I need a quote for a project I'm looking at making. I need the code writing for it. These are examples of what I want to make. And The device will probably be made with a cr2032 battery and an attiny chip and an on/off switch, speaker and a button to select the sound once turned on. Once active the selected sound will randomly play once every 20 mins - 4 hours. The device needs to sleep between sounds as the battery needs to last at least 1 year switched on 24/7 So the code needs to be extremely power efficient. A test clip will be used to write/program to the attiny chip before shipping.

...the back of the baseball cap. When the cap falls off the person's head, the buzzer alarm will go off. An accelerometer cannot be used since there may not be a lot of velocity once cap falls. The device needs to be able to sense that the baseball cap has fallen off, and battery should have enough power for at least a 30 day period and be easily replaced. Device will be used indoors so not subject to sun or heat. User should be able to adjust buzzer volume, turn it off and on, and see a small light indicating when battery needs replacing. Device cannot emit harmful energy as it will be near the users head. Person we hire must have experience to design the circuit and design the full enclosure. The enclosure strap must wrap around the back of the baseball cap stra...

...the spinning machine. When we remove the 100-150W 1250 rpm AC motor from the washing machine and replaced it with a similar 24V 250W 1500rpm DC motor, it worked fine, except that instead of alternating the direction during the agitation cycle (clockwise-pause-anticlockwise-pause) it always went the same way (clockwise-pause-clockwise-pause). If we reversed the polarity of the connection to the battery, we got a reversed direction. Therefore, the clockwork wash timer was reversing the polarity of the AC motor ok, but was not reversing the polarity of the DC motor. We require an electronic circuit that allows the DC motor to reverse. The cycle is something like - 10 seconds clockwise - 5 seconds pause - 10 seconds anti-clockwise - 5 seconds pause which is repeated until the time...
