Happy with your reply, I am, hmm. So, no resistors? not even between arduino and switches? Because I see pcb boards (aka carriers?) with resistors pre-soldered. Thanks!

Hello! I'm almost at this point with my build. I have almost everything to star testing, but i have some doubts. Im using the same components as you are in this picture, do you need to solder any resistors? If yes, which one and where? Thanks

I'm gonna stick with the 3.7v out of the charger then, not step-up. I'm still unsure whether i'll install the magnetic switch or not, it depends on how much i will be able to do in terms of coding. My blaster will gave a neopixel flora on the front and double led strip on the barrel. My question was regarding the "Neopixel Stick (for PLI/Status bar)". I want to understand the point of it and if it's a "must have" part.

Thank you so much for the help! About the battery charger, I thought i needed a module just for charging the battery and make the output 5v intead of 3.7v, something like this: https://www.ebay.com/itm/5V-2-1A-Charge-Discharge-Boost-Protection-3-7V-4-2V-Battery-DC-DC-UPS-DIY-Module/283579416463?_trkparms=ispr%3D1&hash=item4206a67f8f:g:VtIAAOSwm5ZdUp5v&amdata=enc%3AAQAFAAACgBaobrjLl8XobRIiIML1V4Imu%2Fn%2BzU5L90Z278x5ickk7PdDazAlGltMLJlUhrWsD%2BwVbzY7X2u0sCJSj7kGdp8Pk0vuUTRhOqJMwDlPrxcEvBayYQJo50SbBUBUb2qM%2FGrvHgprHtDH4DauroygJvazD2hugnkHMxYs%2Fb7XDvnAG8PYKwvq2JzH%2BKmsxql8WT%2BU1FuIx7dGlysC5CfAh%2FcyLemyGtwiXBD3dmQqCQeLOAH2Viaeywf6I1yZTHAKmFhDxeZ9bRmrsRAYHVz5k0rUiVEIoRQsDJlHh2TJqJf3KBSgEZmriYmDLU4n1E6PKbMItIHfdKjCqr4eeWVPC37E36qqguh4ambWrs4KjA%2BvZXR0UVQ2kAHq8hSppiVp8vD3Y%2BIijwn1RzWHgrYw9e1L6eIwTZwpUYIKC6o18hoRvbTxEo5HH4PAsm8pDrqpShaYe%2FIcibIkk%2B2cDj8DJjH1iTDixHVMTH0CCOgcLtZXIb0%2F5t0JqBF9XvsLXrQ%2BFPmerDXMS%2Fqz9lCXGu3HhSLQojjUPHVJAVPIEBVuJ%2BCBDuRVY8HAGpH%2FJHZ7sk0xXN8z%2F0%2BV2OT1xi%2Bhnv%2FSoIckIXu04s6F8mOUKT7%2BYykTPbGdpDQs53kHGA35IYGE%2F55hrFaTnpGCeoNTJF4VSmdCDWV9OT4owLhQBJHrca5tP1MmBSPlLRu7dV0ceO1gl5f62r%2B%2Fvl2%2BO65JGveUOuA8LXNk9iBogE5imfEIDt83HBYyS411c%2BW2GK3PVlvX6GWB3u0bo0u2U6I56xiF7BVmhRmo1%2BgoECU4v%2Fe1bYC0owL9jzqpjdueJenv45jJiXRAqzBo3yR9BmDjIMEZ%2FCA%3D|cksum%3A28357941646378a8ed3f56e541d898bdfd88ce676739|ampid%3APL_CLK|clp%3A2334524 About the stereo amp, more speakers, more volume! It seems easy to install, i'll post about it in a few months when i have all the parts (we know what happens with stuff coming from china, it's not quick) About the OLED, I've seen some blaster on youtube with both but probably have the scope display on a separate circuit? I want to know more about the magnetic switch because it's a cool feature but i need the right parts. About the strips, that's what I thought. Actually, I have another question. Is the neopixel stick really necessary? because i see it hidden on the "bullet chamber" most of the times. Thanks!

Good evening! This is my first post, so hi everyone! I hope all of you are safe in these troubled times. I completely new to blaster building but i'm a fast learner. I just started 3D printing a E11 blaster. It's a replica designed to receive electronics and i decided to go with the Arduino version. I understand that these items are all I need: - Arduino Board (Atmega 328P) - DFPlayer module - WS2812 stick - RGB neopixel flora - Microwitch with long hinge - Li-on battery and holder - Battery charger/step-up for charging the battery and convert power to 5v - PAM8403 stereo amplifier because i want 2 speakers - 2x 2w speakers - 0.91" OLED display - wires and JST plugs - main switch - usb plug for charging only And now I need some help with the last three items - Can i run 2 LED strips on the barrel? My model has a inner barrel and i wanted to glue one strip on each side. Can the arduino run both strips? - I want to add a aux switch to change modes and a magnetic switch on the magazine for the reload sound, can I do both? - I'd like to know if I can add a second OLED on the scope with this setup. This will be a fun build. Thank you in advance
