    Servo Dog Relay Control

    I found my problem. It was a dumb mistake on my part (I'll blame it on my age - I'm 72?). I mounted the TIP 120 transistor to a common heat sink but I forgot to insulate each transistor. When one was energized I was getting feedback from the mounting tabs. Everything is working properly now. Thanks for the suggestions.

    Servo Dog Relay Control

    Thanks for replying Jim. Yes, the servo dog output channels are set to digital outputs. The output pins do switch from 0 to 5 vdc. When I tried this with the PN2222 transistors I had a base resistor of 2K2 which dropped the base voltage from 5 to approximately 4.4 which limits the current to about 2 mA, when I tried it with the TIP 120 transistors (which are Darlington transistors) the voltage dropped from 5 V to 3.6 with a base current of about 4 mA when using the 820 ohm resistor. The 12 VDC power supply is providing power to both the servo dog and the relays. To me it appears to be some type of feedback which would power all of the relay coils. I just can't imagine from where. I will try to increase the base resistance and see what happens. I'll let you know when I get to work on it later today or tomorrow.. Thanks.
  3. I hope somebody can help. Apparently I must be overlooking something. Here is the problem. I am trying to control 4 relays to control a DC motor (forward and reverse) and some 12VDC LED lights. The relay switching is accomplished by use of transistors and the relays have 12 VDC coils (See the attached diagram). I have done this before but I was using only 1 relay. I am now trying to control 4 relays, when pin 3 goes high (which controls relay 1) all of the relays become energized but all of the other pins are not energized. I have tried this with PN2222 transistors and TIP 120 transistors with the same result. Any help will be greatly appreciated. Thank you.

    Time Scale not Moving

    I found the problem. In the tools menu there is a section for playback preview. Contained in that section is a selection for the "fast playback marker", I unchecked that selection and the scale is now moving with the timing grids. Thanks for all that replied.

    Time Scale not Moving

    Yes, I am clicking on the far left arrow to play the sequence from the beginning. Thanks.

    Time Scale not Moving

    There are a couple of options for the timing grid. "Lock timings" and "drag events with timings". I tried checking and unchecking the options but the condition still exists. Thanks.

    Time Scale not Moving

    I'm using PE version 4.13.18 Pro. On playback, the timing scale does not move with the sequence. Is anybody else having this problem? I used an MP3 music file and I'm wondering if I should be using a Wav file instead. Thanks.

    Timing Marks in PE

    Thank you very much!

    Timing Marks in PE

    I should have made my request clearer. I'm not talking about timing grids, I'm referring to beat marks. Sorry for the confusion.

    Timing Marks in PE

    I’m just starting to get familiar with the pixel editor. Can timing marks be added when sequencing in PE? If it’s possible, I can’t seem to see how it’s done. Thanks.

    Oldest Sequencer Here?

    I'm curious. Who is the oldest sequencer on this site? I'm 71!

    Change Clipboard Size

    Is there any way to change the clipboard window size? It gets very crowded and the text gets hard to read. Thanks.

    Power Supply for LOR Servo Dog

    I use an old 12 VDC battery charger that has a provision for a jump start. It works great with plenty of ampacity.

    10 W RGB Floods

    Thanks for the information it is very helpful. Sorry for the delay in response but I haven't been able to get back to the forum until now.

    10 W RGB Floods

    In relation to an incandescent flood light, about how bright is a 10 W RGB Flood? Thanks.
