- Опубликовано: 31 май 2015
- Hi Guys, so I FINALLY got around to making another video, hopefully answering some of the questions out there. One thing (of many) that I forgot to mention was the power supply for out linear actuator aka "the kickstand" is an old power supply from my laptop. Also not sure if it's obvious or not but the "kickstand" will stop at any point in the travel. Who knows maybe next year we'll add another linear actuator and get a left/right adjustment - we'll see! I hope you liked it.

Hey, I love this. I notice it has been a while since you made this. Do you still have it? Have you made any improvements? Do you have build instructions??? I desperately want one. Great job.
Great project. What size tires did you use to launch the balls
Hey I was wondering is there was anyway to get like a small blue print in terms of the sizes? I think this machine is phenomenal.
Awesome. I want to build one. DO you have dimensions and sizes for everything?
Hi I was wondering if you had plans to build this? I'd like to assemble one for my team, but need a few more specifications.
Hey I
was just wondering what the specifications are fr the two motors you used
Sup, one question: what's the power (HP) and the velocity of the motors (RPM) ?
do you have a list of the parts by any chance?
I have been trying to do the same for over one year, my main problem is the vibration the wheels produce. Can you tell me which tires you used, please?
Love the paint job! Looks strangely familiar...
BasementPaul My favorite "utility" paint!!!! :-)
Hi. Can you give me information about the system you used to control the elevation?.
good job . what is the kind of wheals and the size
How many degrees is the angle of bending a round iron?
For the linear actuator, how did you make it go up and down to control the feeding of balls? I can’t figure that out. My hope is to have it go up and down every ten seconds or so
Is there a bom and some building instructions? I wonder if this is possible with battery operated motors as we don't have power sockets close to the pitch
Can you pls tell me where you got each part
How far apart are the wheels?
Nice design. How far apart are the wheels, relative to the size of the ball? Or, what size ball are you using/distance between wheels.
Currently I have the wheels set where there is ~6.5" between them. I've run 4&5 size balls at this distance with no issues (lately it's all 5's). Earlier I ran larger spacing, but I found out that if the balls get WET then they tend to slow way down as the wheels slip. By running them closer (more) squeeze doesn't seem to hurt anything and still let us work good if the dew was on the grass.
What is the space between the wheels?
How wide are those tires ?
RacinJacin! I was super excited to hear that you are in Ohio. I would absolutely love to get one of these to throw dodgeballs! It would be amazing for practicing my catching daily. Is there any chance you would consider putting one together for me to purchase? I’m in the Cleveland area.
Hi Chelsea, Projects like this are a labor of love, meaning that to do it CHEAP requires a LOT of labor. It would become cost prohibitive pretty quick. However IF you can get resourceful, you could build your own! While I welded this one - you could get some of the bolt together aluminum extrusions often used in industry (McMaster-Carr is helpful). But to really do it cheaply you're gonna need to get your A-1 scavenging skills going.
How does the SCR give you 90 dc ? Does it convert the 120Ac to dc?
Where can we buy it from and what is its exact price I need to buy one
hello, could you put the amazon link for the motors please?
hello this is really great could you post a video of all your wiring and some basic measurements ?
Patrick Crawford I don't have any wiring schematics - I just followed the SCR manufacture's directions. My wiring directions won't help unless you have the identical controllers
Hi, quick question. Did you have to reverse rotation on one of your motors so that one shaft runs clockwise and the other counter cw?
David DeJoia Yes, I swapped the motor leads so one goes CCW and the other rotates CW.
What kind of motors are these I'm looking to buy some, how much can I look to pay for one of these motors
what rims and tires do you have on it? how did you mount them to the electric motor?
+Michael Meyer I made some adapters (I understand not everyone has lathe access), but I think you can purchase them from the guys who supply parts to build go-carts. - I see they sell hub adapters - I bet you could get them to work. I bought the steel rims and tires off Ebay - having used them for a while now - they are OK , but nothing to get excited about because they do have some runout - and now that my son is 14 we're wanting to crank up the speed so better balanced wheels are my next upgrade - not sure if I will spend $ on some aluminum go cart stuff or just find something I can modify from the surplus store. I hope that helps
The engines are 19V, 2500 rpm and what is the power? What was your wheel diameter and how did you do the speed control?
I think he said 90 v not 19
Hey ... I wonder if you could tell me what power the motors have and if you know where to buy these or similar ones! thanks ;)
David Placke I used USED 90VDC 2500 RPM motors -1/3 HP (IIRC) I bought off Ebay for dirt.
Hey I was just wondering what power source you used, I really enjoyed your design, and I will be trying to recreate your idea. Just leave a reply. I subbed.
I used 2 SCR controllers (each motor separate for individual speed control) 120AC Input. 90VDC motors. Everything was scavenged used or surplus - much from Ebay.
RacinJacin392 thx so much
What did you use for motor speed controllers?
SCR controllers - 120V in 90DC out
hey man love the machine. Can you please tell me more about the motors and how you mounted the rotating wheels on the motors?
The motors are just DC motors - nothing special. I actually made the adapters, but you can buy those at the Go-Cart supply places as they use them alot.
@@RacinJacin392 are the adapters for the wheels? So there is no need for a lathe?
@@ricardo5670 Check with the go-cart people. Last I looked they had "hub adapters" that were identical to what I made. They may also be the right place to get better quality (balanced wheels/rims) as some of those carts REALLY fly.
Hey RacinJacin, I wonder what is the benefit of a 90VDC motor over a 24VDC motor? Also I cannot find anything off-the-shelve to connect the wheels easily to the motors..
I used those 90VDC motor ONLY because I had them and the 90VDC controllers laying around. For wheel adapters - look to the Go-Cart industry - last time I looked they had Hub Adapters that would work depending on your motor shaft.
@@RacinJacin392 Thanks. For some reason the motor vendors don't tend to mention the axle diameter. I'll keep searching for a 12V DC motor 2500rpm with matching diameter so that I can use a 12V battery for 2 motors, keeping about 1000rpm.
what engine are you using??
Hi just wondering how you manage to attach the motors to the wheels thanks
I made hubs, but if you would rather buy them - go to the people who sell Go Cart parts - they sell hub adapters that would work well.
I would be interested in buying one if you were selling?
How much for the blue print? Pretty please
Can I buy one or can you post a tutorial on this
What is inside the yellow enclosed box near the launcher for? Thanks
Those contain the SCR motor controllers - one for each motor.
What is that you used for the kickstand?
Ryan Dahl It's nothing special - a linear actuator a buddy gave me - I used an old laptop battery charger to run it (you can see the battery charger strapped to the top of the launcher)
Very interesting! I'm attempting to build this as a project which is apart of my engineering course!
Hello sir my names Ernesto were you successful in building ball launcher?
Do you have any measurements for this awesome machine. I would like to build one myself.
Edward Cunningham I never drew up any plans, everything was seat of my pants so to speak. I'll try to grab tape and get you some numbers.
@@RacinJacin392 great machine you made. Have you ever tried ut to see how well it worked? Put up a video if you can.
@@cfomusic73 We used this for several years. As my son got older we just kept increasing the ball speed. Never chrono'd it but they were really moving. It would launch them nearly the length of the field, but that's not how we used it. We did goalie training with it. The only issue I ever had was at the mega high speeds - the wheels needed balanced.
Hey I want to build one. Can u help me with some measurements
Yes I would like to build one as well
Where do i buy
Do you still use this?
What would you charge to make one? I am in Ohio and would love one for my son.
I'd love to Amanda, but without product liability insurance I'm afraid I cannot. :-(
IIRC these are 1/3 hp motors 2,500 rpm (i run them much slower) 90 VDC SCR controllers
Hello
I want to make a soccer ball. I need you to provide me with engine information and construction drawings
Email: sajadghadari1378@gmail.com
If you went to a junkyard where would you be able to find the motors and controllers. What I mean is where would the motors be located on a car, motor bike, etc.
For DC you can find cordless lawnmowers on Craigslist--once the batteries die, people tend to junk the thing instead of buying new batteries. For AC you can find plug-in electric lawnmowers, which include the actuator (turns AC to DC). I suggest lawnmowers only because the motor is easy to access and the RPM is high. Treadmill motors are also high RPM and easy to access--and easy to get cheap or free; the circuit boards and tread begins to slip long before the motor burns out.
Any research paper
Hi! I'm started as a marine engineer student and got the idea of a ball launcher for a school project and found your video for inspiration.. I could really need some help with some drawings or just anything. The assignment include time management and an economic aspect.
Hope to hear from you!
Kind regards
Malik from Denmark
Hi Malik, Sorry for the delayed response, but you caught me during race season! The materials used here are way overkill (I used what I had laying around or what I could get for free). Unfortunately I never made any drawings. The main frame is 3"x3" steel tubing - I'd have used aluminum if I had my choice. The ball "chute" is made from common electrical conduit. The motors are 90VDC 2500RPM (I run much slower) and I used old school SCR controllers because they were free. I made the motor spacing adjustable - extra squeeze is nice for when the balls are wet and doesn't hurt anything when they are dry.
Its totally okay, i'm still in the brainstorming part. And I fully understand about the measurements but where did you get the materials from then? Like, the "conveyor" the ball is following towards the wheels? Was it already welded or did you have to do so? (Sorry, my English is not my first language) thanks for the response!
@@halvkat The ball chute was made from electrical conduit. it's easy to bend, but you need to be very careful welding it as it is galvanized. ALL of the galvanized coating MUST be removed to weld. If you try welding on galvanized metal it will produce nasty gases that are harmful. Crystal clean or don't weld it. You could also skip that hassle and get good clean tubing to start with. I had conduit laying around so I USED what I had.
@@RacinJacin392 ah allright. I have some standard iron/steel tube at my school. Another question though. What connection is there from the engines to the wheels on top? And is it just some ball bearings down by the ground wheels? Thanks so much for answering me it's kind of your machine I'm working out from. Kind regards.
The only problem with the machine is that unless you can count with a power point in the field you are unable to use it.
TheDRIBBLER2 The original intent was to use it around the yard, but we have brought it to various fields - in those instances I throw a generator in the back of my truck!
TheDRIBBLER2 haters gone hate
There are several tutorials on how to make a cordless lawnmower work off a car battery. I am sure the same would apply here.
What horsepower are the motors you used? Awesome machine
312 Woodworking I also want to know how many watts thease motors are.
312 Woodworking IIRC I used 1/3 HP motors, 2500 RPM , 90 VDC w/ SCR controllers - all used off Ebay
I've been inspired to make my own one. I was looking at the motors you specified and they are about 140 dollars each. just wandering how you got yours for so cheap
+William Ambrose I bought used on Ebay!
thank you I'll keep my eyes out. how fast can it shoot the balls out would you say.
+William Ambrose It'll shoot them out scary fast - the limiting factor for mine right now is the balance on the wheels - they start to vibrate when we turn it up to scary fast range. I was planning on looking into this to see if I couldn't balance them - these particular motors go 2,500 rpm - we've never been full speed yet.
+William Ambrose I have wanted to try getting some solid wheels - figuring I could easily true them up on the lathe, but haven't been down to the surplus store to try and scrounge any. My son plays U14 - this shoots them faster than the 14's kick - that's why I've been a little lazy in solving my balance problem.
Ok thank you. what brand/model number are the motors
Love to buy one off you. Seriously your costs for goods, r & d +$500, labour +$???, and shipping to my Canadian address. Our U11 girls would be very appreciative in how we can use this for their development
What is the model number of those motors?
were you able to find out ?
These are some old motors - I have bought some of them off Ebay from Industrial Surplus vendors - to buy this exact motor new would likely be expensive. Used off Ebay was cheap. I wouldn't recommend focusing on this exact motor - anything close would be fine. These are 90VDC 2500rpm 1/3 HP IIRC
sir do we required high torque motor
So you don't need a lot of torque to spin up the motors, but when shooting quick consecutive shots is when you notice the torque. Under powered motors will drop the speed and your quick follow up shot will be less power. The motors I used were pretty good. Also the motor controller parameters will affect this a well. I fiddled with the parameters some using the OEMs instructions.
Would you be interested in making one that would be able to launch around 50mph? I’d be happy to put a deposit on one and drive to pick it up. Provide me a quote and let’s talk.
I want one really bad. Would you be willing to help me or sell it to me!
Can I buy this off u
Hi. Can I order it? I need a machine like this.
Sorry this was just a project showing what one could build out of scavenged parts and a welder. Nothing available to sell.
Can you sell me one?
Hey brother, would you make some to sell or have you made any for sale.?? 😃😃😃
I would definitely buy one. But I'd like to see it work too. Lol
I noticed you didn't show how it worked..hehe
Thnx
Hi, I'm in Tampa, love the game of soccer and have a daughter in it as well. Was wondering if you would make me one? If so, how much? I think it's awesome. Great job!
Ole Peitersen Sorry Ole, I'm afraid the labor would kill the deal ;-( But don't let that keep you from building one. To do it cheap you just gotta source some deals and maybe use a favor or two.
Ole Peitersen ur bad at life
I need this I’ll pay you 300
$100 machine in parts but $3000 in labour hours
Dude I will pay you 200.00 for my hs program !!
I'm from germany...i didn't unterstand anything...(sry My english is bad :( ...)
TrinityRandy Your English is far better than my German!!!
Selbst wenn man das ins deutsche Übersetzt ist der Satzbau falsch bzw. grammatisch nicht richtig. Naja
I would like to buy one.
Alex Guevara Marulanda Sorrry, just built the one for my son. :-(
Hello do you have instagram id like bait more information?
