Hi all,

perhaps some of you BOP owners has noticed that replacing the helmet light bulbs with LEDs makes them flicker. Since I wasn't happy with this I made my own PCB that is a "drop-in" replacement for the normal chase light board. I know there are other solutions to this problems, but they tend to at least demand that you disassemble and remove parts of the helmet and I didn't want to do that.
The replacement board uses PWM to fade the LEDs to make them behave more like a standard light bulb and there is no need for any special LEDs. The board also creates a new regulated DC supply voltage (~3-9Volt depending on a resistor on the board) for driving the LEDs which is essential to make them flicker-free. This DC supply connects to the LEDs by routing a new cable from one of the previously unused pins on a board connector and attaching it to the free-hanging cable connector leading up to the helmet (white-orange cable).
It is also possible to use the board without the PWM-function (by adding a jumper to the board) and using it as a drop-in replacement for the normal chase light board together with light bulbs. Then there is no need for the extra white-orange cable, just remove the old board and attach this new one.
I'm not quite sure how the legal part is regarding making replacement parts for pinball machines. Perhaps someone can enlighten me, and if there is any problems I will remove this post.
I did this replacement board for myself, but I have some spare boards if anyone is interested and if the legal part is okay?

Here is a video (although hard to shoot) of the board in action together with some purple/pink LEDs:

Hey all. We now have successfully installed pellew's board in our BoP.

Here is a video of the final result. We're using retro LEDs:

Here are some photos of the installation:

Looking good! Thanks pellew!

#3 1 year ago

Hey pellew, I'll take one if you have an extra, how much is it?

#4 1 year ago

Does this use the original software control or does this board do it’s own lighting effects

#5 1 year ago

Hell yeah - Good work. Wish I was at this level of bad assery! (god mode )

Quoted from alveolus:

Original software control.

#7 1 year ago

Hi pellew, I would take a board also if you have anymore and would ship to Canada

#8 1 year ago

Great job jsa, looking good!

I have some more boards, but they are not ready to ship yet. If you are interested then send me a PM and we'll take it from there.

The board controls the light just like the original board but with added fade and no flicker.
It would be possible though to make a firmware for the board that controls the lights in a different way. Any ideas and I would try it?

Can you do the whirlpool and ramp for Creech next?

Quoted from alveolus:

Would most likely not be a problem to fix, but I don't own a creature so I can not measure on it or test a board in it.
The same goes for the white water topper, it would be possible to do if I had the game.

#11 1 year ago

Some information, the boards are fully populated. No soldering required. You only need to add LEDs and one new cable to feed the helmet with a DC voltage from the new board.

#12 1 year ago

PM sent, I'm interested!

#13 1 year ago

Hi all, the interest for the boards seems to have increased beyond the numbers I have at the moment. I'll respond to PMs later today and I'll see if I manage to fix boards for all.
Thanks!

Thanks for making this, yes you better make more, this could sell VERY well.

#15 1 year ago

I've replied to the PM's I got and for those of you that are on the waiting list I've got good news; I've ordered some more boards and components so no one will be left without a board if you want one.

That's great. I hope you ordered some extras.

I’ve been considering pinduino for the helmet, but this board is super snazzy!

Wow!

#18 1 year ago
Quoted from Chosen_S:

Yeah this opens up the possibility of using all kinds of different bulbs like Comet Crystal Fan bulbs.

Wow!

The Pinduino does a lot more (I have one) but this looks to be a simple and elegant solution.

PM Sent this looks great, I have good LED's and the flicker was not a problem but the instant on-off was distracting. It will be nice to have the fade back.

#21 1 year ago

First batch of boards sent today. Will try to send the rest within a week.

Boards are tested before shipment, but if there should be any problems just let me know.

#22 1 year ago

Installation:
First install LEDs in the helmet. Replace the old board with this new board and reuse the plastic spacers. Then you need to add a cable from the new board according to the pictures. I added a white/orange cable which is the same as the original cable feeding power to the helmet. Disconnect the 1 pin cable connector that is under the playfield/helmet and (by using whatever method you like) connect the new cable to the connector piece that is going up to the helmet. DO NOT connect this new cable to the wrong piece of the connector.

pellew Do you have a part number for the single wire molex connector for the DC power to the head? Also what wire gauge? 18 awg?

#24 1 year ago

Hope you plan to keep making these, most definitely would like one in the new year sometime

#25 1 year ago
Quoted from mavantix:

Yeah, this wire and connector should have come with the board. Not a happy camper here. That looks to be 22 gauge.

Well he did a great job on the board, so can’t be too unhappy. I just went to install tonight and realized I need to source some wire and the connector... I suppose I could just pull the wire from the back box wherever it connects, but figured I’d make it easily reversible by sourcing the connector and wire. I can order extra and make you one, once I figure out what I need.

Quoted from mavantix:

Probably one of these two:

https://www.greatplainselectronics.com/proddetail.asp?prod=03-06-1011
https://www.greatplainselectronics.com/proddetail.asp?prod=03-09-1011

More likely the first one, judging from the size of the wire, which seems to be 22awg.

#28 1 year ago

Hi,

MustangPaul sorry for not being clear about this. I think I wrote this privately to the first customer but forgot to mention this in the thread/information sent to you, sorry!
I have not looked up the part number for the connector, but the one ForceFlow mentioned (Molex housing 03-06-1011 together with Molex crimp socket 02-06-1103) seems correct. The wire gauge is not critical regarding current, but 22 AWG would fit the 0.156" IDC-connector going to the board and the crimp socket.

Once again, sorry about not informing you guys about the need for a cable and a connector!

Yeah the board is beautiful buy in my opinion it should have been plug-n-play. If you would make me one that would be great, I'll pay you of course so let me know. Thank you.

#30 1 year ago

OK, I ordered enough wire/crimps/connectors to make up 10 wires... in case anyone needs one.

#31 1 year ago

I would take one if you’ll ship it to Canada. Thanks mavantix

Thanks @pellew - I'm really happy with the results of the board and I think it's a nice little addition to a BoP machine. I included your board in a short write up on my latest BoP tinkering - http://www.enteryourinitials.com/2018/12/18/bride-of-pinbot-2-0-repair-service-log-7/

i installed the board with the extra cable.

But i got a strange thing... The helmet LEDs are not correctly working....

I made a Video

http://sendvid.com/lyn2qkgd

I changed q24 and q26 but it din't help.
Don't know what and how to check now.

Maybe you can help me and give me some input

Thank you and Best regards

Hi,

it definitely looks like problems with the clock and data going into the board (most likely the data). Tried to swap back to the old board to see how it is working?
Are all LEDs on the board steady RED except the one next to the CPU which should be flashing about 1 time per second?
Can you tell me the number written on your board that you received, then I can look at my pictures to see if something seems odd.
All boards are fully tested before I ship them, but of course it's possible that something is a bit "loose" that might have moved during shipment. A cold solder joint for instance.

Hi Pelle,

i will look today evening for the boards and make some photos.

I will try the board swap on Thursday...

But here the pictures and the vids from the actual situation with the Board: https://sendvid.com/g7l1fvgx

Hope it helps...

I think is the cable or a conenctor on the PDB - but more infos on thursday

pellew is there any chance of getting one of these?

#41 11 months ago

Vimtoman you've got a PM.

Can anyone else give some feedback on how the boards has been working? I've had one case where two different boards didn't work. Since it is somewhat hard to troubleshoot via email we couldn't find the root cause.

Thanks!

#42 11 months ago

Pellew , mine has been working great since day 1 . Its been about six months, since I bought it from you

#43 11 months ago

No issues here, working great!

#44 11 months ago

I believe I was your first test, or close to it, and it's been working great every day.

I also brought this game to an expo/festival and had hundreds of plays, a lot of good exposure, and no issues.

pellew are these still available? pm sent

#47 10 months ago

Hi all, I've had some family issues to deal with but now all PM:s has been replied. I have some boards ready for shipment and can make a few more if needed.

Nihonmasa please send me a PM and I'll give you some more information.

#48 10 months ago

I just asked for one of these boards, it will be nice to have the correct fade effect.

When I'm not at work I'll have to look at this thread again for details on what I need for that wire.

Nice vid of it in action. What is doing the other lighting effects on the face?

I ordered one, now I need to get some wire and the connector. Is the one linked above correct?
