    Latching relays in a control circuit

    A couple of cautions when you are working first time with micro boards. 1) When using a scope make sure ground clip on probe cant accidentally brush up against other part or board leads or board traces. Make sure when connecting to a ground on board it stays put. I have hosed more boards than I...

    Latching relays in a control circuit

    pulse streams of desired width and inter pulse delay. Pulses are outputs to a pin to initiate an action like turn on a fan or light. So I make a pin go high to turn something on, wait for a time delay I set, then make pin go low to deactivate that specific task/job/event. Yes, using blocks...

    STM32-Based Data Logger Experiencing Occasional Communication Errors After PCB Assembly

    If you have a DSO place it on infinite persistence, say 100 mV / box, 10 mS to start, edge triggered around 50 mV, AC coupled, and look at power rails for pk-pk noise. Type of bypass caps for bulk matter : OSCON is polymer tant Use a bulk and a ceramic disk (.1 uF) in parallel. Is...

    ECU repair

    The xtal osc can be sensitive to probe loading, so just bring probe tip close to osc C's or xtal, scope on roughly 100 mv box to see if its running. Probe at 10X. Can you identify the pin that puts ECU to sleep ? Any documentation on it ? Have you asked ChatGPT to try to find more docs or...

    Also if you can get access to a good optical inspection scope look at soldering, amazing how much stuff made with marginal solder joints. Look for cracks, areas where solder does not appear to have "wicked" onto the leads/joints. Both sides of board...
