    Using transistor to switch power on with a push button

    I am trying to turn on a Picaxe board and remain on until the program finishes executing. The problem is that with a single cell LIPO (4.2V fully charged), the output voltage of the transistor switch is 2.4V. I may be using the wrong transistors or trying to do the impossible.

    Using a single cell LIPO to power an 8M2 or 14M2

    I am planning to use an 8M2 or a 14M2 on a project to drive 8 UV LEDs. Considering using a 3.7V LIPO. What can I expect to happen when the voltage of the LIPO drops below 3V

    UNABLE TO INSERT jpeg image or include an attachment on a new thread

    When I try to insert an image on a new thread, things work until I click UPLOAD then nothing happens. The same thing happens when I try to attach a file.

    PWMOUT on C.0 and C.2 of a 14M2

    I am trying to drive two glow plugs from a model airplane engine. Using a two MOSFETs (IRFZ44N) attached to C.0 and C.2 on a Picaxe 14M2. I connected the gate of the MOSFET to C.0 and added a 10K pull down resistor. The source connected to ground and the drain to one of the plugs terminals. the...

    Using PNP Transistors on a 7 segment display. am I doing it right?

    I want to drive the Cathode of a four digit seven segment display (common cathode) using 4 PNP transistors. I would appreciate any comments telling me if my schematic is correct or not specially regarding the four transistors. Thank you in advance for any input. Andrés Rodríguez

    Using Datalink to display the value of a World variable

    I have built a dynamometer that measures RPM and torque. The value of the Torque is measured using strain gauges. The variable I need to display in datalink is the result of the product of the RPM and the ADC value from the strain gauge. My question is how do I send the value of the variable...

    Using Servo [45536],B.0,201 on a Picaxe 20X2

    Does he preload value used to change the pulse frequency remain en effect after I issue the Servopos command? Or do I have to repeat the preload after every Servopos command? Servo [45536],B.0,201 Readadc10 B.4,w0 w1=w0*10/68+75 Servopos B.0,w1 ...........

    Question regarding a Darlington Array (UDN 2981)

    On the attached schematic, Pins 7 and 8 on U2 (UDN 2981) are connected continuously to +5V. I wonder if that will cause damage to the chip. The reason I need to do that has to do with traces crossing each other on the PCB.

    Saving battery during idle time between events (PNP/NPN trans combination)

    The schematic shows a circuit designed to monitor the condition of a Mercury switch (shown as a button in the schematic). To avoid using battery power while waiting for a event, I'm trying to use the two transistors as a switch activated by the Merc. switch. Once the program reaches the end, the...

    Using a PNP transistor as a switch

    I would appreciate comments, critiques, recommendations on the attached circuit. The purpose of this circuit is to periodically monitor the voltage of a 4 cell battery (6V). The frequency of the sampling is handled by software on the Picaxe 08M2. To avoid draining the battery through the voltage...
