Our company is working on a cooling project. We’ve so far miniaturized most of the PCB (product control board) to allow the controls to interface with the refrigeration system. The next portion of the project is to work on miniaturizing the refrigerant system. The goal is to make a very small miniature refrigerator I am seeking an Cooling / Refrigeration Product Engineer that has experience in this
To design and implement a working Hydroponic Sensor System using Arduino. Sensors required: 1. Light Sensor to give measurement in PAR 2. pH Sensor to test Hydroponic system pH 3. TDS and EC sensor to give measurements in PPM and MicroSiemens/cm respectively 4. Humidity and Temperature sensor Expectations: An Arduino setup that can be implemented on any growing structure. Kindly read about the structures available for hydroponic growing (Deep Water Culture, Nutrient Film Technique, Aeroponics, etc); for ideation of the model you will be designing. The overall build must be economic and cost per part to be minimized as far as possible. Interested Lancers are requested to connect with concerned person for details. Looking for creative individuals who can put in unforseen cards on the table. Overall process for project: 1. Fill in your request 2. Get in touch 3. Initial cost for parts are to be borne by the freelancer which will be refunded in full. 4. The same bill of materials needs to be shared with the project poster (us) before making the purchases 5. Project ideation phase with the project poster. 6. Implementation and Final payment excluding your bill of materials cost. Bits and Bites: Project has a timeline. Expected delivery in 2 weeks from the day of appointment
We have the schematics of a complete CCPWM power supply unit. It outputs PWM high amps current. It uses Mosfets. The schematic need some changes. Some parts of the schematics will be removed. Arduino Due will be replaced with Nano V3.3 and we will add a trimmer and a LED 4digits. Since the schematic is ready and we only remove parts and do few changes, you understand that this Job is based in previous design. It will be an easy task with few hours of work.
Need custom bootloader for SAMD21G18 to load firmware updates from SD card and decrypt. Also need matching pc app to encrypt updates before distribution. Basically need to combine the SD SPI bootloader from this project: [url removed, login to view] combined with the security features from this project: [url removed, login to view]
Looking for a controller 'box' designer to develop DC Motor controller: 100-4000 RPM CONSTANT TORQUE, reversible direction unit. The motor will drive a small lathe via belt/pulley drive (this is NOT part of this job description) . The control box will have a basic functions: a display showing motor speed and CW/CCW direction switch). Your job is to - select DC suitable motor which can provide constant torque - design control unit - to provide working prototype, bill of material, Gerber files for PCB production I am looking specifically for an engineer who has extensive EXPERIENCE in the field of motor controllers, not a student or just someone with understanding of the circuitry but with no practical experience in production. Applications not supported with adequate and relevant portfolio will not be considered.
We want to create a Labview program to control a Zaber X-Z stage([url removed, login to view]) to move a probe across(in 10 micron steps) the sample and make AC(1000hz) measurements sourcing from Keithley 6221(about 10mA) and measuring on 2182. Datalogging required.
We want to outsource the hardware design and embedded software development process of a gps tracker device, which can work with both solar and battery powered (even with both together), send data through GSM/GPRS/NB-IoT. Mass production concerns should be taken account during the desing phase.
i have a PCB board which is designed using SMT ( smart mount technology ) while we are required to have normal pcb boards where you drill holes then weld the components if its possible to be fix let me know please i need a new one today using multisim but if you can do one using pcb wizzard it can work as well
Poszukuję osoby która wykona projekt oraz prototyp urządzeń telemetrycznych w oparciu o mini komputer BEAGLE BONE BLACK. System składa się z oddzielnych modułów komunikujących się w standardzie RS485 (M-BUS, MODBUS, GSM, moduł główny, AI, AO, DI, DO). W ramach prac należy zaprojektować płytki drukowane oraz wykonać działający prototyp. Hardware bez prac programistycznych. Posiadamy już opracowaną koncepcję i schematy części urządzeń. Szczegółowe informacje zostaną udzielone zainteresowanej osobie.
