Wallboxes and wipod

Clones,
Check the motor carry-over segment on the WOM--be sure it's not "burning" at the end of it's travel. If burnt, remove "burn", and fill with non-conductive epoxy--also, if running on "free play", or this is happening only when "credits" are available, check the motor start contacts for burns--remove/burnish, as needed---Ron Rich

I am currently running it with a coin mech, might try it using free play

Clones, it looks like you've tried a lot of options for noise suppression.

I've only put a 0.1uF 630V cap across the 24VAC line ...and to no avail. I haven't delved any further with placing the cap across any other part of the circuit.

With further testing it does seem that my premature cancellation issue is less frequent. With this amount of testing, perhaps the contacts are "cleaning up" creating less spikes??? Typically I only play the 3W1/iPod/cdadapter about every 2 months.

Additionally (to my previous observations) I had 2 cancellations at the end of the motor cycle and once with adding a credit through my rigged credit switch (switch across the coin switch).

Hi
I emailed datasyn, maybe might get some suggestions. Just wondering if the cancel cable is at fault, seems to be bare wire inside a clear pvc sheath. Myabe the entire cable needs to be shielded
Clones

Hi
No burning evident on the motor carry over or no burn marks, have emailed data syn no word yet. I did try shielding the cancel cable and earthing one end of the shield but no difference

Hi,
I have done a few of these and had this problem before.....

What power supply are you using to power the Wipod ?
Im not an electrical genius , I don't understand why , but changing the 9v power supply normally resolves this issue........
I have used cheap ones from Ebay/China that cause it on some machines .

The 507 normally is very good. Not had problem with the cancelling issue on that machine.

Regards

Hi Jacko
The power supply is the one that came with the whole kit, its a model sf-889, input 110/220 volts AC 50/60hz and output 9 volts dc 1A and made in China. Where did you source the your power supplies from, will try that and see if it makes a difference

Hi,

Just any 9v 1amp plug in power supply with male jack plug , the guy I normally get them from has sold out but buy from a UK seller ( about £5 posted) , not from Hong Kong and you should be fine.

Also , have you got the ipod outside the wall box ? sometimes the metal case touching the wallbox inside can cause it to pause ...... I always put the ipod in a rubber skin to protect it from interference.

Let me know how you get on , I have had this a few times and always resolved by changing the power supply and/or ipod ( Gen 2 are very reliable , gen 3 tend to cause problems )

Regards

Jacko

Hi
Yes i went into Maplins today and typically they were sold out so will have to wait a week or to get one, i would put the ipod outside the wallbox, i think the ipods i currently am using are a 4th generation and 3rd, though i am not fully sure. Will let you know how i get on

Hi all
Ed from Datasyn kindly replied to me even though his wife is not well, he sugguested putting a 0.1uf cap or higher across the cancel button contacts, voltage doesn't matter as the cancel cable works on 3 volts. To be sure i put a 0.22uf cap across the cancel button contacts( i used a metallised polyester cap rated at 50 volts). I left the cable shield and ferrite rings in place.
So it seemed to work, hadn't much time this afternoon to test it but i made a few selections picking a total of 8 songs for each selection run and no songs canceled, so it works, will let ye all know in the coming days how it goes.
Clones

Thanks for the feedback!
I'll try the same and report back.

Yes it will be interesting to know if it works for you, tonight i tested it over 20 times picking from 6 to 12 selections with no songs canceling during each selection run

I tried jumping a .1uF and various other caps up to 1 uF across the cancel switch.
Unfortunately it seems to have made the infrequent premature cancelling... more frequent .

As I've said before, it's really not an issue with my setup (I have a free play switch).

I was hoping that I could support the fix that Clones was able to implement so that this would work out for Rob-NYC (who's solutions, on this forum, to all our troubles has been so valuable).

Hi
Thats a pity, i thought i had the problem cracked, i have been using the wallbox since with no canels even up as high as 18 selections. What type of cap did you use. The additional things i did include a rfi filter on the mains input on the supply before input to the transformer and power plug for the adapter, a ferrite ring on the signal line inside the wallbox, a ferrite ring on the cables going into the adapter including the cancel cable, a suppressor between the 25 v ac and common inside the wallbox, also a DIY shield on the cancel cable(which consisted of tin foil wrapped around the cancel cable and earthed(grounded). However none of these made any difference until i soldered a cap across the contact points on the cancel switch. I don't want to tempt fate and remove any of them. It would be interesting to know if a different power supply for the adapter makes any difference, The ipod i use for the seeburg is a 2nd generation one and for the rockola's i use a 3rd generation nano and a fourth generation ipod

Clones, I DO think you've found a solution! ...albeit, for now, at least for you. Hopefully others will try the cap (and maybe your other measures) and report back to this thread.

I think that those experiencing this problem and that find this thread in the future, should try the capacitor first. Adding a cap is a simple thing to do. I jumpered mine in - easy to try different values and remove when it appeared to not be my solution. (...Hmm... could the long jumper leads be an influence??). I should state that before we makes any conclusions as to the efficacy of the capacitor, I haven't replicated your measures. (It would be more valid if I could replicate your measures exactly and report back my findings. Maybe in the near future, time permitting, I'll try)

It could be that you've dropped the possibility of causing a cancel with your other measures and that, when adding the cap, have dropped it below the threshold for a cancel. However this wouldn't be supported by my observation that when I add a cap (without your other measures) the problem clearly worsened.

I used a number of caps (digging through my parts drawers) 0.1uF , 0.22uF, 0.47uF and a 1.0uF - voltages varied from 50 to 630 - but the voltages should be irrelevant. They were what I had on hand. These were ceramics and polyester types. Consistently, I noted that the cancellation issue clearly became more frequent with any of these values to the degree that when I added a selection, the previous entry would be cancelled every time. I did note that the cancellation frequency did not appear to change with the capacitance value.

I think that the fundamental issue is "noisiness" of the system and in that regard there are numerous variables at play (the home electrical environment, the wallbox itself- the condition of its contact, the position of components ....etc)

Regardless, for me, I think that this is an excellent product. It's great for the home market, for someone who wants a little retro look without having another full sized jukebox. I wouldn't hesitate to buy another!
