    Hello I had someone build me a laravel website. We accept membership payments through stripe. However my stripe API key and secret key is being used for what strip calls card testing. Literally thousands of small payments are being charged to my stripe account. Stripe told me to implement radar which I did and now they are charging me for every blocked transaction by their radar. Are you able to look at my website and find out how they continue to get my API live key and secret key. I have rolled my keys and use different keys on stripe but every time I put them on my website they get access to my keys. Is this something you can help with? Thank you in advance Greg.

    I need to ship you these circuit boards for diagnosis. I have an OEM gear selector for an ICE powered car. It has 5 buttons and associated LEDs. It normally outputs a CAN or LIN bus based signal. But I just need it to output a "to ground" signal from each switch. What I would like to do is ship you the circuit boards and a spare connector with the pins. I need the LEDs associated with each of the 5 switches to illuminate when each switch is engaged, and the unit sends out a “to ground” output from each of the 5 functions, via the connector leads in the attached image. I tried to just solder on leads to the switch contacts of the larger board, but the leads and solder would not adhere. One can see in the image where the large board was burned at the ...

While IGBT's and MOSFET's are used for very similar applications it should be noted there are two main differences, the MOSFET tends to lean towards high frequency low-power switching whereas the IGBT leans towards lower frequency and harsher switching conditions, these are just the common assumptions. Due to the fairly ruggedised features of the IGBT they normally have around a 10us short-circuit capability and a higher voltage rating which makes them a lot easier to protect. The MOSFET ...

When the GPIO signal is HIGH, it will open the gate and allow a 3.3V square signal to pass to the output (input ). When the GPIO signal is LOW, it will shut the gate circuit and output will be 0V. Circuit must be tested in LTSpice using the attached 'Input ' for the input signal, and using the attached 'GPIO PWL ' as the GPIO signal.

    Refer to attached circuit schematic. The transmitting raspberry pi (TX pi) sends a data signal to a filter circuit. The filter circuit removes the 3v that the rpi sends when there is no data streaming in order to protect the amplifier. The amplifier then sends the data signal down a long wireline to the receiving Pi (RX pi). The problem is that the program uart_rx is expecting to see 3V to indicate there is no data. Instead it sees 0V and thinks this is data so it writes empty values to the file. The scope of this job is to modify uart_tx.c files and uart_rx.c files so that the transmitting program sends a start of file indicator, and end of file indicator. The receiving program should then be able to identify when the data is starting so it can start to write to th...
