Videos - The Coin Bot

Jump to This Time	Transcription Text
00:00:00	in this video I'm hoping to attach all of the jst connectors which hopefully will drive all of the peripherals for the coin bot you can see here on my silicon mathod I have the jst connectors lined up and ready to solder the two-
00:00:12	pin connectors are going to be used to wire up the Linux switches that will allow the stepper Motors to home and the three pin jst connector is going to be used to drive the addressable LEDs that light the coins in the coin studio and I
00:00:28	have the software setup so that 1 three pin connector can drive all 50 LEDs for both the bottom and top Studios I'm not sure if we'll get to testing this evening I know I've overestimated in the last few videos how much I can
00:00:40	accomplish in one evening but if I get these soldered on and soldered to the peripherals I'm going to be very happy so we'll see how far we get and as always I need to put my glasses on so I get about 50%
00:00:52	smarter here we go I have a female connector here in my left hand and a male connector in my right hand I'm going to attach the female jst connector to one of the limit switches and the male to the other and that way
00:01:07	you can't mess up which ones you connect the first lead attaches to pin 22 on the Raspberry Pi motor stepper hat and the second lead attaches to ground I'm just going to Mark those out and I want to leave as much extra
00:01:26	wire on both of these as I can that will allow me to Route the wires into the actual coin bot um pretty far put a little black mark on there you can can kind of see that that's going to be my my mark for where I want to strip
00:01:42	the wire but we're going to actually cut the wire with a little extra length there and see it's beyond the mark that I made then we're going to go back to the wire strippers and cut it off at the
00:01:59	Mark you see that I have a good amount of the insulation cut off there both of these connections are both stranded wires so I am going to Tin those wires first now that I have these wires tinned
00:02:22	I can actually add them to the zipper motor hat I stuck a piece of painters tape on the bottom of that so you can see it ground has a little wire poking through it and pin number 22 has a wire poking through it so that's going to be
00:02:35	perfect for this limit switch Lu in both spots chop that off a little bit shorter I bent those at 90 degrees and I want to Tin both of those put a little fleux on both to make sure you get good heat transfer apply a a little bit of
00:03:00	solder to both and again you can just barely see a wire sticking up out of pin 13 and also another one here on the ground little flux last peripheral the solder on here is for the addressable LEDs we cut them
00:03:22	off just a little bit beyond the stripper Mark we stripped the wire actually on the Mark we're going to add some flux and Tin all these wires again now the three pin jst connectors I've decided to solder from the top of
00:03:39	the board just to make it a little bit easier on myself and uh so we'll see how that goes here in just a second the yellow data pan I can actually connect to that little solder blob that's right at the end of that resistor right there
00:03:50	and again this jsd connector you can again see a little piece of wire poking out right there and another one right there we need to solder both of those so we add some plx there's only one more connection
00:04:07	that needs to be attached directly to this hat um I'm not going to attach this with a jst connector since it's going to remain pretty close to the CPU I think I can hardwire this so the CPU fan wires are stripped there
00:04:24	and add a little flux then tin the end so now I think we have everything necessary to operate the coin bot at least at a very preliminary stage so all the jst connectors connected or were soldered on without too much trouble so
00:04:53	that's kind of nice for change but you can see that I I soldered the the three pin jst connector directly to the top of the board the other two pin connectors I attached to the bottom of the board and
00:05:09	I also attached a CPU fan to this now the other thing that I want to do in order to neaten this up just a little bit is I'm going to add just a couple of dabs of hot glue just to organize the wires a little bit better
00:05:22	make sure that they're held down there is nothing utilizing the 3vt rail right now so I think I can actually use those holes for the hot glue to hold things in place so I'll I'll do that so now we just have to wait for the
00:05:43	hot glue to harden and I'm just I'm thinking that that will keep me from you know as I'm assembling the coin bot it'll keep me from yanking those cables out of their solder joints I think that's all set up and I'm pretty happy
00:05:56	with the way that they turned out and again that CPU fan is attached too so the only thing left to do is to wire everything together and actually test it but I'm not doing that tonight I think we'll call this a video today is
00:06:09	day 19 of a 30-day challenge I've given myself to post a video to YouTube Every Day in the month of September and as I've said in the past few videos if you have any feedback for me about how I can make better solder connections or make
00:06:17	better videos please leave a comment down below but for now that's my two cents thanks for watching everyone have a great night and stay awesome and
