    Default Build/Parts List Check: MHS CFX In-Hilt RGB Tri Cree LED

    The time has come!

    Dad and I decided to start a new Father-Son project this holiday, and we settled on building lightsabers! This will be our first lightsaber build ever. I know it's advised to start super simple for a first build, but as this is a Father-Son project, and my dad is extremely well versed in electronics and mechanical know-how, we decided to go big. Below is a list of parts, the MHS Builder design, and a diagram depicting the chassis and wiring. A note on the chassis: I'm using a NB sized chassis for the CFX, as the CF doesn't fit, and I saw a thread here that showed how to modify a NB style chassis slot to accommodate a CFX board.

    Looks good to me, though how are you going to have access to the 2.1mm charger port externally, not seeing any machining for it. Unless you plan on doing that yourself. I would also get some 24 gauge wire just for the Tri-cree LED, you don't want those to melt when pulling 1A each. Though that's just me being cautious.

    Good idea about the 24 gauge wire.

    The recharge port is going in-hilt. It'll be the first thing after the metal chassis disc, and it's not going to be accessible outside of the hilt. Unscrew the pommel, pull the chassis out an inch, plug it in. Thought about putting the port and a RICE port on the hilt itself for easy access, but I decided I preferred the way recessed switches look without a box, and it saves money too.

    If he’s using a Tri-Cree, 28 gauge is fine. It’s when you use Neopixel, that’s you need thicker gauge wiring.

    Solid job spec’ing a first build...my gut tells me you will find something missing as many of us have, but TCSS is top notch in getting orders out fast, and while shipping is not cheap, it’s totally worth it with how fast your gear gets to you!

    I think the internal recharge port is totally the way to go and always do that...and I have modified the acrylic discs a ton with files/Dremel to do all types of things. I suggest buying some extra chassis discs in case you break one doing a mod...also suggest grabbing extra basic parts in different varieties (resistors, screws - hex, grub, etc, an extra recharge, star tape, some o rings, covertec etc.). These are low cost per part and won’t hurt to have around as odds are you will have a blast and do another (or 10.)

    This is totally preference, but in retrospect, I wish I had not chosen predrilled jokes for AV switches and gone with tactile momentary and drilled them out myself on my initial saber which was also MHS. AV switches are great, but take a ton of room in the hilt, require lots of extra wiring and are a bit of a pain to secure. You could do a crystal in there for the same space, similar wiring, and some creative chassis disc work.

    Last...as this was more than I intended to drop, but you brought me back to my first build...the biggest help I have found is having the right tools for the job. Can make things infinitely easier. Lots of posts out there on great gear to make the job easier!

    Best of luck!

    Sorry...one more! Subscribe to the TCSS YouTube channel. Rob from Genesis Custom did lots of TCSS tutorial videos. I watched them before I placed my first order (and ordered helping hands before I hit submit on the TCSS order.). Then I actually played the video for the component I was building or wiring as I did it for the first time...test at every step so you can isolate issues. Build a test rig for your battery so you can test all of your leds when you wire them up. And for your first recharge port, wire it up externally, use the just to connect the battery externally and test all connections with your multimeter...make sure your +\- are proper before getting anywhere near the board! Bottom line...research (read the full NB manual from the plecter website), watch tutorials and test all throughout!
