    This project involves reviewing a PCB design previously developed by another Freelancer to make sure it working and then continuing on to develop the Firmware. Currently I have completed PCB's that have been manufactured but not tested. The device is based on 2 key components, a broadcom APDS-9250, and a STM32WL. Together these components will count the pulses of a flashing LED over a 1 hour period, then transmit the count over the Sigfox network. I have attached a PDF that gives a good overview. Please reach out to me with any questions and I'll do my best to answer. I would prefer to move quickly here and would like to have this project completed in 2 weeks - subject to the functionality of the existing board. Let me know if you are interested in collaborating. ...

    An automatic Braking system is an intelligent mechatronic system includes an Ultrasonic wave emitter provided on the front portion of a car producing and emitting Ultrasonic waves. An Ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective Ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose.

    I have a couple of holiday homes with an airco (LG s12et) and a NILAN compact P heat pump. Both systems can hear or cool the house but at this moment a lot of times the systems are working against each other because the temperature that is wished, is not synchronising. Maybe this can be done with modbus or something. The project is: -selecting the right hardware -maybe write some programming language -With the right instructions I can connect the hardware myself easily. I have attached the NILAN specifications. The LG airco specifics are easy to find online.

Then I’ll need another 16 pin vertical female header for the lcd screen (pin 1 from the adapter would need a trace going to pin 1 on the lcd adapter board, 2 with 2, etc.) As for the components I’ll just need holes so I can solder them.

    I need help with design of a device which can take DC (variable voltage as input from 12-60v) and convert that into an AC 110 volt 60 Hz (also 220 volt 50 Hz) and such device should be able to sense voltage and frequency of the grid , where we are trying to feed , and based on that, it can synchronize frequency and voltage. And then it can feed power to the grid, but say from usual household plug so that it becomes portable device for say uto 1000 Watt portable solar power generators, wind generator. If output voltage sensing is difficult then probably 2 models - 110volt 60 Hertz and 220volt 50 Hertz. Also need a prototype shipped to me to US, along with all the schematics, drawings, designs.

Anything I can find on the market are small toys without the much required power. It has to use larger loudspeakers - not the tiny kind you see in any bark repellent It has to allow change of frequency (as in adjusting for a specific dog/animal). From what I understood it has to emit ultrasonics around 20kHz-25Khz (in case of dogs) so it is not a such complicated device but I need someone to think about all these aspects and compatibility of the electronic pieces.
