Hi Helmut, thank you for your message.  In theory this is a good approach, but the issue you are having is caused by the quick pulses of the light not being powerful or long-lasting enough to activate the sound module.

For your setup, I assume you are looking for something like this: https://youtu.be/0W8jxvJjVvY. But with laser cannon sounds instead of machine gun sounds? We are just beginning work on a modification of the machine gun board to include laser sounds built-in. This might work for your setup-- please let me know what you think. Thank you again.

Helmut Senft Hi Helmut, I just ordered the circuit boards for the new setup.  These should arrive by the end of the month, then we will get to work!

Helmut Senft Hi Helmut!  Thank you for the reminder.  I have the boards now, which means I can focus on the sound.  Sorry if we've already discussed this, but is there a specific laser sound that fits with those cannons?  If you have a sample or video you could link to, I can see if we can replicate the sound.  Or we have some general laser sounds we could use, if there is no specific sound you're looking for.

Thank you.

Helmut Senft OK, thanks, we'll have a look.

Helmut Senft Hi Helmut, wanted to keep you updated!  I've been working on the sounds and think I'm close.  Looking at the gun in the original photo you sent, I assume there are two lights, one in each barrel?  And do they fire alternately or together?

Helmut Senft Understood.  Triggered by the same type of remote control unit?

Helmut Senft Hi Helmut, thank you for checking in.  With the global shortage of electronic parts (you may have read about it), our sound chip supplier has been very slow in responding to us.  We are still working to get something developed as quickly as possible-- we have not forgotten and will be updating here when there is news to share.

Helmut Senft Hello Helmut, thank you very much for the order and for keeping in touch!  We are finally close to having the parts needed to make the kits we have been discussing for so long.  I am going to make a note on your Ecto-1 order sheet so we know to contact you again before shipping-- hopefully we will have good news by that time!

Helmut Senft Hello Helmut!  We have your Ecto-1 ready to send and I also have prototypes (finally!) for the laser sound setup.  I just want to ask: can it be ok to have 3 cannons maximum firing at the same time?  Your original diagram had four, but we have the sound chip that can play 3 sounds at the same time, so if this can work for you, please let me know and we can get it finished.  Thank you!

Helmut Senft OK, thank you.  We'll work on finishing up the new module.
