This project is a fully of typicals designs where usign a microcontroller, pwm output with 2nd order rc lowpass filter this signal go to op amp non inverted amplifier configuration, the op amp output must be boosted (with bjt or jfet) I need 100ma minimun current in the 0-10 volts output. Requirements • 2 pwm outputs • 2 RC 2nd order lowpass filters • 2 non inverterted op amp configuration, output must be boosted (bjt o jfet) • 2 relays SPST (with transistor bjt and protection diode) • 1 relay SPDT (using 2 relays SPST with transistor bjt and protection diode) • 2 RS485 (using pcb module) • 2 GIOP • 4 Leds • 4 push buttons The time of realization is 7 to 10 days, the design software that you can use is Eagle or Altium.
This is for a wifi connected battery operated device, which connects to the local wifi, sends messages when commanded by user to a server, which then sends push to apps. The device contains user selectable option to allow voice connection to the app. Please respond point-by point on your capability and experience in aspects of this project. - Design of a long-life battery operated pendant, containing: * Embedded microcontroller with RF wifi * Mic and speaker for voip * Good robust connection to wifi * Connects to local wifi when button is pressed * sends a packet to server * allows for short voice communication if the option is selected * Has low battery, health check feature * can be updated by the server automatically (only when user has pressed the bu...
Brief Description of the Assessment: Design a basic LED driver circuit using appropriate semiconductor technologies: Generate a SPICE model of the given LED from the data sheet provided; Design a suitable driver circuit; Perform a SPICE analysis of the resulting LED driver circuit; Evaluate the performance of the resulting LED driver circuit.
I want to start a smart camera business I need someone who can build a really cheap or can suggest me alternatives
NOTE: Budget is $500-1000 CA. We have a trailer park near Toronto, Ontario. Canada and will be updating the power distribution for 225 sites coming from a 300 KVA transformer. The Professional Electrical engineer has to be authorized to design and sign the completed drawings for ONTARIO. Canada. If you can help with this project, I can provide further details.
