I'm an average guy doing some not so average repairs. When there isn't a manual or video for a repair, or if there's any tips or tricks to make the job go faster, I will post it here to share with everyone. If you have a request, I'll try my best to help. Good luck, and KEEP WRENCHIN!
Arduino Coin Sorter
Brief overview and demonstration of my ECE 4600 Capstone project at Wayne State University, Fall 2016. This coin Sorter is fully automatic (unless it jams), and is powered from a standard 120 VAC outlet. All I/O and controls are handled by an Arduino Due micro-controller.

Honda CB175 Starter Clutch
Переглядів 18 тис.9 років тому
Taking a look inside a 1971 Honda CB175 that won't start and fixing a problem with the neutral switch.
Thanks for sharing the video on cb175 starter clutch. How do you rectify that squeal when using the electric starter?
Could you share the bolt information shown around 2:10? I got the M16 1-1/2mm but hoping to confirm the length before I order it.
do you have a more detailed explanation on how exactly you managed to detect the different coins? how do you feed back the voltage from those coils to the arduino?
Thank you, I learned a lot, very useful, cute sounding kid
Awesome video. I take it all those "Phillips" screws are actually JIS screws?
Do we need to drain out the engine oil before removing the starter clutch assembly?
I also have the same question, also did you get a new left gasket or reuse the old one?
@@jasonzimmerman7379 The crankcase has to be drained before you take the side cover off. Or, you'll end up draining it as the cover comes off. He said he was going to use red RTV because he didn't feel like waiting for a gasket.
Anyone know if it can still function with a few of those broken tabs? @3:45 I opened up my case and found only a couple still intact.
We are currently making some experiment about this sir. May I ask some question regarding about this especially details of parts and construction of coin sorter. Your project is fully related to our research. Thanks in advance and I hope you respond sir.
How does the light sensor work here ? Does it check for the diameter of the coin ? Or what does it do ?
What I thought 🤔
May I know how the IR sensor can be response so fast under that kind of sliding speed? Appreciate much if you can answer my question.
I just went through this process only to find that the symptoms persist after replacing impacted caps and springs. I am curious to know if your large chainring has any in and out play (mine does)? As well as the direction that you installed the small sprocket. CMSNL shows the small sprocket with a collar facing out buy I can't see that in your video.
This was quite a while ago but I do not recall any play in the large sprocket. The collar you speak of is indeed facing out, but the illustration on CMSNL is very exaggerated. If you look at the small sprocket within the first ~2min of the video, you'll notice a light colored ring that the chain appears to touch, but doesn't, that is the "collar". Since there is no tensioner on the chain assembly, these sprockets are installed at the same time, as long as they are coplanar, the chain will ride straight, and should start the engine. Another note, I never removed the sprockets for this repair so whatever way they were before is how they are now. You mentioned you replaced only the caps and springs, check the rollers as well, any flat spots or damage can cause the clutch to slip.
Thanks for the reply. I believe I installed the small sprocket correctly. I did have some play on the large chainring for sure, though. I can move in and out about 1/8" at least. I figured that was what the small retaining clip was for. I did no replace the rollers. I suppose I should have. After attempting this repair it seems to have fixed nothing. Side covers will be coming off shortly. Thanks again
Small update, I took the side cover back off to watch as I ran the starter,. What I found that my chain would deflect (much like yours but much worse) and hit anything and everything inside the case as it spins. So I have ordered a new chain and will see what that does for me. Rollers look good but they may be up for replacement if this doesn't solve it.
Do you ever hear rattling from the starter chain slapping the large sprocket retaining clip? I took a slo mo video of mine and you can see the slap action: ua-cam.com/video/W-U0b_Z3yVo/v-deo.html
Such a cool lil' bike!
Anyone ..who knows abt this project fully please reply...
Hey, I'm in Rochester Hills, MI, wanted to see if I can get you to help me build a modified unit.. with a few more bells and whistle?
Excellent vid brother! Super cute kid thing too.
Yeah. The kid thing made me smile and reminded me of how I miss those days when mine sounded like that. If I could do it over, I would give them my full attention and be cognizant that these days/years are fleeting. And then they’re gone. Sorry. A bit off topic. Thank you. Very helpful vid.
sorry jammed at first HAHAHA~~~
finally, someone uses solenoids! I love you
really great work. I'm really curious how exactly the coil coin sensor work. did you attach some oscillator to you coil? what is the *"Instrumentation"* you used? also what library did you use? can you post a link? thanks.
Because the circuitry is complicated and this video was created strictly for the purpose of presenting this project I did not go into these details. The circuitry was based on information found here. www.best-microcontroller-projects.com/coin-detector-and-counter.html
I already saw this. I actually bookmarked this site way before I asked you. Thank you, I suspect you're using a similar method and you just confirmed it. I found it odd that there is little information about this on the internet.
averagerepairman ..I’m working on similar project...how can I contact you ...need some details abt project..
Cm Chetan what details are you looking for? I've long since scrapped this project for parts and to just clear space. I'll help with what I can.
@@averagerepairman6519 to give proper credit, this is patent US4998610A
I orderd 3 springs, caps, rollers to rebuild my CL350 clutch. I should have waited till I pulled it apart. The rollers and caps were good, only the springs were collapsed. Could have save myself about $20 by only buying 3 springs. I assembled it without taking ithe clutch totally apart (the 3 phillips screws) as suggested in an earlier comment. A small flat blade screwdriver , a finger and needle nose pliers made it easy. I also left the starter gear and retainer in place. I also have my starter off for a rebuild which will be a cleaning of the commutator, new oilite bushings, brushes and brush springs.
the coils you used in this prototype is to create the hall effect? and which currency of the coins are you using mate? and are these coins magnetic materials or not?
I appreciate the questions! First, the coils are used as a comparison device, one coil sends an AC signal the other coil receives the signal (much like a transformer), and the difference in the two is compared with a differential amplifier circuit and further circuitry for filtering and amplification. The output of all of this circuitry is a DC voltage which correlates to the metallic composition of each coin. Second, this is U.S. currency; Quarter, Nickel, dime, and penny though I did not test with pre-1982 pennies which have a different metal composition. Third, I don't know the specific magnetic properties of each coin, but each coin has either a different metallic composition or different amount of each metal (coin size). How these metals disturb the field created by the coils is how the circuit can identify one coin from another. I have seen other coin sorters which use actual magnets to affect the speed of a coin as it rolls down a track to make the coins drop into different areas based on speed.
Thanks !
Top man, I wondered what it was that those coils do exactly! Many thanks for that.
Oh one other thing, where can I buy those coils? - Do they have a specific name? (Okay sorry thats two questions lol)
I actually made these coils. I bought a sheet of 1/8" lexan (plexiglass), cut out 3 rectangles, 2 big one small. Superglue them into a sandwich with the small rectangle in the middle, get some 30 AWG enamel coated wire, wrap it around the center, and you have a coil. I used some elmers glue to hold the wires together on the side of the coil where they begin.
nice share bro. did u have a video how to assembly kickstart spring. i keep broken it twice. please share if u have it. thanks
Great video! Question, what is that sound at 13:08? The third time you started it, there was a binding noise? My k6 175 does that too, I was thinking it was a sign my starter clutch needed to be replaced, but if your brand new starter clutch is doing it too it must be something else.
That noise has to do with the crank and cam position in relation to letting off the starter. It's letting off the starter right near the spot when the cam is pushing on a spring, resisting rotation or even causing a slight reverse rotation a few degrees, while I've already stopped supplying power to the starter. The overrunning clutch then slips on the crank since it does not have enough power to fully engage or overcome the reaistance on the crank, creating the wonderful squeal. Hopefully that makes sense, lol.
averagerepairman Awesome. Thanks for the explanation about that sound. My 1972 CL175 has it also (when I use the electric start). So, am I safe in thinking that the sound is normal operation and not a sign of a current or potential problem? I hear it quite frequently on classic Honda bikes. Thanks you.
Thanks for this! Gonna try it on my '72 CL350 tomorrow. Hopefully get that sucker back on the road!
Is there any trick, to get 'the starter clutch' cover off? Took out all the cover bolts, but something still holding cover-on ? ? ?
Are you talking about just the small circle cover or the crankcase cover? I don't remember anything other than just the screws, I used a rubber malley to help break it free.
You're getting resistance from the permanent magnets in the rotor being attacted to the stator in the cover. Wiggle it off.
helpful video. however, i just did this for a '73 CL350 which has an identical starter clutch, and i have a few pieces of advice to offer: 1) use an oil filter wrench to hold onto the clutch while you try to remove the center bolt, 2) you can use your rear axel bolt to pop the clutch out instead of buying the puller bolt, 3) you can replace all the springs, caps, and rollers without taking the clutch apart (by that i mean not removing the 3 screws). just i used a small angled pick to do this. hammering the clutch with an impact driver may have cracked the first plate inside. it may have already been cracked, i'll never know, but regardless, you can change all the screws, caps, and rollers without even taking it apart. my bike now starts on first try.
Just like the commenter below me, I owe you big thanks! This explained to me what the forums could not do before I dug in to do the starter clutch on my 84 Honda CM250. Great instructional video
I've been looking for a video like this for a good year! Finally understand the starter clutch. Many thanks!
