I purchased drop-in speakers for a snowboarding helmet from ebay but got terrible feedback when I mounted them in my bucket since the HA mics were right behind them inside the ear caps so am using earphones for now. I bought some copper tape to try and insulate them but have not had time to mess with it since. I would rather not use headphones as well. Sent from my SAMSUNG-SM-G930A using Tapatalk

I just saw this on the PJRC.com site. I wonder if this would have helped with the line noise issue. Sorry, I know it's a little late Glad you got it figured out, though. https://www.pjrc.com/store/audio_ground_isolator.html

The beauty of this project is that you can do just that In the original specs/tutorial, you can install the thumbwheel volume pot. You can use that to control whatever setting you want. It's just a pot and not connected directly to volume or anything. The next release will have a way to control these settings and more...stay tuned

Are you on iOS or Android? I can send you a dev app once I'm done. I didn't get any more time to work on it over the weekend I'll be putting up a tutorial on the updates needed (hardware) to TKTalkie to get it all working. I need to work on the interface for iOS. Android is almost done.

Lol almost...have a few more function tweaks then need to tweak the layout for different devices...so far just testing on an S7...getting close [emoji41] Sent from my SAMSUNG-SM-G930A using Tapatalk

Little tease for version 3

Hey guys...I've setup a Facebook page for TKTalkie. Check it out and give it a like if you would https://www.facebook.com/TKTalkie-1868123370130329/

Yay! Glad you got that working! Looks great and the videos sound great. I need to get me one of those brackets. I have not had a chance to work on my step-down yet. Been working on a major upgrade to TKTalkie It should make life a little easier...

Very cool! Looks great!

Good idea. I ordered the step down as well. Sent from my SAMSUNG-SM-G930A using Tapatalk

oops nvm I found the thread on requesting 501st access!

TK-81113 Requesting 501st access please. http://501st.com/members/displaymemberdetails.php?userID=23036 Thank you!

Hmmm...am I not a Legion Member? TK-81113 of North Texas Squad of Star Garrision. I've purchased legion merch before.

Great update! I don't mean to be "that guy", but whenever I click on any of the merch links I get a not found error with a message saying "you don't have permission to view that."

TKTalkie V2.2 Well, I got ONE of the things I planned to get done over the past weekend lol...I got The TKTalkie software updated to v2.2. This version has a few changes: 1. Added support for Line-In 2. Added support for Line-out 3. Changed effects from pre- to post-processing This means a few things: 1. The post-processing adds a little more power to the signal, so you'll probably have to turn down the gain on your inputs and outputs in your config file It also allows for better processing of the signal so that it's easier to hear how it is affected as you tweak it. If you'd rather use the pre-processor, just comment out the line the setup function where the post-processor is enabled. I left the the pre-processor enable commented out For example, after switching to using the Line-In/Outs and post-processor, whenever I started talking it was just a loud hissing noise...then I realized I had the gain on the noise generator up high, so once I cranked it down everything was fine. 2. I found that using the Line-In and Line-Out works MUCH better, at least for my setup. I'm using a powered wireless mic, so I can adjust my input and output signals a lot better. I am getting LOT more volume out of my system and am able to avoid feedback since the signal is not so "hot" any more. In the new tutorial I show how to adjust the line levels of the line-in/out to get the best signal for your setup. 3. I switched to a 50-watt PylePro speaker (instead of the 10-watt Aker) and am much happier with it. I am running from the Line-out on my TKTalkie to the Aux/Line-in of the speaker, and letting the volume on the speaker handle all the load. The result is I can really crank it up. So when I'm in loud situations at a Troop I can be heard well. I updated the tutorial. It's at www.tktalkie.com/tutorial. In the tutorial I also show how to use the serial monitor of the Arduino IDE to make real time updates to your config. I plan on making a video soon. So my setup is a wireless mic running into Line-In on the TKTalkie, then I'm running the Line-Out to the Aux/Line-In of the PylePro. I had to tweak my settings because it was really loud using my old setup when I was running the mic into the microphone input and using the headphone output into the mic input of the speaker. I also took the volume pot off my TKTalkie. I just manually set my board volume to half, again so the speaker can handle the volume controls by itself. Here is my current setup: # Set overall output to about half [volume=0.5000] # Line-In level. Valid values are 0 to 15 [linein=7] # Line-Out level output. Valid values are 13 to 31 [lineout=27] # Plays when TKTalkie starts up [startup=STARTUP.WAV] # Background loop [loop=CHATTER.WAV] # Background loop volume [loop_gain=0.010] # Voice channel gain on the mixer [voice_gain=0.3500] # Trigger level to turn on speaker when I start talking [voice_start=0.1700] # Limit to turn off the speaker when I stop talking [voice_stop=0.020] # Amount of time to wait (in milliseconds) before playing a sound effect [silence_time=350] # Not using a PTT [button_pin=0] # Sound to play when PTT is pressed [button_click=TKT_CLK3.WAV] # Button sound effect volume [button_gain=1.0000] # 1 = Microphone, 0 = Line-In [input=0] # Not used since I'm using Line-In [mic_gain=15] # Volume level of the sound effects on the mixer [effects_gain=0.2500] # Equalizer: 0 = off, 1 = Bass/Treble, 2 = Parametric, 3 = Graphic [eq=3] # 5-Band equalizer since I'm using graphic. Values are -1 to 1. [eq_bands=-0.75,0.00,-1.00,0.00,-1.00] # Gives the voice a tin-can sound [bitcrushers=16,41000,16,8096] # Background noise level for when I'm talking [noise_gain=0.1500] # This is only used when using a serial interface to program in real-time [debug=0] I think I'll be taking a break from software tweaking for a bit. I have my setup working great...field-tested at my last troop. I'm going to work on the Bluetooth capability first, then I have an idea for a companion project for TKTalkie that I think will be a great addition

Have you tried desoldering braid? Much better than the pumps and manual vacs...just hold it with pliers because it gets hot lol...essential part of my soldering kit Sent from my SAMSUNG-SM-G930A using Tapatalk

I would be interested to see the whole setup. I have a 12V battery similar to yours and am going to grab a step-down board and do some testing because I'm also reaching the point where I would like a single power source... When you say noise, is it EM noise from the fan motors? I was getting some from the fans when I installed the hearing assist, but I replaced the connections from the mics in the earcaps to the board with shielded wire and it went away. Since you're dealing with a power line, though, it may take more than that. And yeah, blowing a 20 dollar board constantly is not fun

I would still be concerned with how many amps the battery is pushing. But at that price, you could try one and hook it up to a voltmeter to see what kind of output you are getting. I've connected my Teensy to a 2Amp charger before and it was fine. That battery pack has USB charging ports, though. Are those already taken?

Just a thought...how many amps is your 12V pushing? I know you can take a USB car charger and take the guts out and use it to step down to 5V from 12V and it will handle about 1 amp.

I'm getting close to needing a single power supply for all my stuff as well. I have a couple more kits that I'm going to try to get to this weekend. Going to try wiring them up in different ways. Also wanting to update the tutorial. I ordered a 50W PylePro speaker that will be here tomorrow to maybe replace my Aker 1506, since it's only 10W. I'm finding more and more in noisy situations the Aker is not loud enough. I'm essentially going to wire up the first of the two kits to use the Line-In/Line-Outs to run to the speaker. I'm finding that by using the headphones out (which is powered) and plugging that to the mic input on the speaker, it will only get so loud before feedback because the signal is pretty hot at that point. Having to adjust the equalizer and pull a lot of the treble out to avoid feedback. It's still pretty loud, but like I said, I've been in a couple situations where it wasn't quite loud enough. Lastly, I found at one troop it would be really nice if I was able to change some settings on then fly, like turning off the background chatter, so I found a BlueTooth transceiver in a box of parts for Arduino and thinking of maybe writing an app that would connect via bluetooth to the TKT to allow real-time updates Would also be great for initial setup I think. Anyway, that's on my wish list for the weekend. I have a troop and then some normal life stuff, so hopefully I have time to get started

That's great! The great thing about this project is you can do pretty much whatever you want Welcome!
