    Boxes. Cases. I need simple coverings for my projects! What do you use?

    For simple one-off projects I have used small plastic (food?) containers with clip-on/snap-on lids these are available locally here from the $1.00 store. You can mount small switches and P.B.'s in the lids, I have used them to house small powers supplies and Micro-μP projects, M.

    Troubleshooting treadmill controller trojan solitude 400

    Not sure what you mean, the board appears to be a PWM controller and has its own P.S. M.

    +DC_out_rtn, what does this mean..

    All of the P.S. I have used that use remote sense lines connect the sense to the +ve and COM out terminals if remote sense is not used.. Which would make sense when you think about it. It would be no different that connecting to the remote load. The spec sheet does not appear to mention it, but...

    Troubleshooting treadmill controller trojan solitude 400

    Well if we assume the board is not the problem, the it is a case of elimination, the other thing you could do is substitute the motor for a 100 watt lamp to see if initially you have power. Can you post pic of the board and show any part No. M.

    Troubleshooting treadmill controller trojan solitude 400

    Does it have a opto or other tach on the motor? This may be the cause if fitted. Also check for load and friction of the deck belt, If possible remove the drive belt and see if the motor operates OK. M.

    +DC_out_rtn, what does this mean..

    That supply appears to have the Remote Sense terminals. In this case a pair of conductors is taken to the remote load to detect any volt drop, and then correct the output accordingly, If not used it is customary to connect the respective +sense and -sense to the main +ve & -ve terminals. M.

    Servo motor used with adruino need no driver?

    Use a logic level Mosfet, IRL530 etc. M.

    Transistor switch suitable to run dc motor?

    For a general purpose Mosfet for small motor applications you can buy the IRF630 for about $1.00. M.

    Electronic circuits work in mysterious ways?

    When I got into electronics, IC chips that were available were out of reach, price wise so we had to build the basic's from decrete components. Look at the basic descriptions for this. http://www.hobbyprojects.com/flip_flop/a_transistor_RS_flip_Flop.html M.

    What Glue

    That's what I use, RTV or Silicone rubber caulk, It is also easy to remove, should the need be to replace a component. M.

    What circuit makes a HIGH by detecting LAST pulse

    This show it a little clearer, if the input is pulsing the output stays low, once the pulses stop the output changes. http://www.falstad.com/circuit/e-555monostable.html M.

    What circuit makes a HIGH by detecting LAST pulse

    Essentially what the 555 does. http://www.falstad.com/circuit/e-555missing.html Click the L to H. Plenty via Google 555 Missing pulse detector. M.

    What circuit makes a HIGH by detecting LAST pulse

    A watchdog timer type of operation using say a 555, if you want a delay after last pulse then either another 555 time out or a 556 double 555. M.

    Checking PIC18F4520 Timer 0 overflow

    To check for TIM0 O.F. is a simple check of TMR0IF in INTCON. If using it to interrupt then it should be cleared immediately after. M.

    Checking PIC18F4520 Timer 0 overflow

    Pic timers have a Interrupt flag on overflow, this can be tested, it has to be cleared once read, this occurs whether the int enable is set or not. I only use Assembly but there must be a simple way in C. M.

    Start up I/O lines of PIC micro

    Look at the manual for configure ports example code (A,B,C etc) for I/O. Most pic's power up with I/O configured for analog enabled where applicable, see p105 in the manual for configure PORTA for example. M.
