I bought the "Black Box" wiring harness from Lermods, but I decided to keep my machine stock. I'll sell the box for 80 bucks and ship it for free.

This is amazing! I have the basic toy triggered off the "H" and find the action less than polished during gameplay, and annoying during attract mode to the point where I turn off the game when I would prefer to have it on.

Any chance you would make this mod or kit available for sale?

Maybe a how to guide, at the very least.

May not totally appease you, but use the child insert by the left spinner, much less active. Also, very easy to add an on/off switch if you don’t want it active in attract mode. I detailed how to do it in this thread with a short video.

Here's my Grogu on off toggle switch with LED. Same button type as posted earlier in this thread, but with the LED indicator wired up. The button is a little too big for the tournament button hole so I used wire cutters to cut out just about 1/3 of the top of the ring the button sits in. This allows the button to fit snug and secure, still look attractive and not damage the cabinet. I'm really pleased with how it turned out. I was going to solder all the connections but decided not to in case I decide to make changes in the near term. For now, all the connections are secured with tight fitting heat shrink.

lock9 DarthPaul Pinballpal Sorry for the lack of reply, I don’t check Pinside very often. I have no problem sharing some details on how I made it for tech savvy types. Finding the time is hard right now as I’m in the middle of a couple retro computer projects at the moment that I need to finish up. I’ll start with sharing important details from the comments of my microcontroller code that clearly explains how I'm interfacing with Grogu. Keep in mind that I use a generic mod PCB based on the PIC12F683 that I designed back 2007 that I use with most of my small projects. It uses transistors on the outputs, even when I’m using relay modules and aren’t really necessary. So, keep that in mind when you see code outputs as high from the microcontroller that it’s actually firing the relay module low.

I guess I'm not opposed to offering kits or just releasing the plans publicly for non-commercial use. I consider this an advanced project build because of modifying the arm and soldering directly to Grogu's control board. My fear is that kits might be too difficult for most and just offering schematics, wiring diagrams, and code publicly is probably just about useless to almost everyone. I really don't want to deal with offering complete builds. If I did, it would be a small run in June and probably wouldn't be cheap. What do you think is the best approach?

Because of the complexity of what you are doing, in my opinion, a kit would probably be your best bet as far as the electronics go. I would like to know how you modified his arm, that seems to be something an average person would be able to do?

Tekman Holy $**t dude! That's freakin' awesome!

I'm onboard for this as well.
I like your build and would like to do it too. Looks fairly easy. I have an electronics background and you have done the heavy lifting. Thanks for anything you share.

Curious if anybody did a 3D printed bracket for animated Grogu? I currently have him held by a solid green wrapped copper wire (hidden underneath the coat), but it seems to move around more than I want it to. Anybody have any better solutions? I have a Ender Pro 5 printer, and tempted to model a bracket for it, but I am a 3d model newbie and it would take me some time before I figure it out.

Hi guys, I present to you my version of the grogu.
For the story, I got loaned a mando pro to be able to work on luke's lightsaber, the lender had bought the pin with a grogu and asked me to install it.
I therefore installed the grogu but I did not like it because the grogu moves too much and randomly, it does not stop when it should and the arm blocked by the ramp, I did not like it at all.
so I reconsidered all that.
I created a program that manages so that the grogu triggers at a very precise moment, that it waits to use the force, then starts again to return to its starting position.
I used the capture of the ball for my scenario.
the ball is captured, grogu moves and stops to use the force and does not start again until the ball is released to return to its initial position.
he will therefore move 4 times maximum in a game (4 razor crest multiball)
for the position, why would you want to put it in the same position as the original ???
I rotated it 45° which allows a very simple installation and to move the arm freely, visually, it fits well and grogu is completely free (head ears and arms)
the arm that remains blocked by the ramp will inevitably cause breakage after a while.
the trigger will be done with the powering of the magnet.
it was not easy to find the right parameters so that the triggering was flawless and that there was no electromagnetic disturbance, I spent 3 days on this configuration alone.
I will have an LE model in some time and I should be able to adapt my system to the magnets of the CHILD under the board, if I succeed, and there is a good chance, the effect will be even more fantastically realistic.
this is a short video to see grogu in action, sorry for speaking french but but pictures are enough
May 4TH ........

Can someone please send me the link for the install instructions for the Lermods Grogu, I purchased a Mando premium and it included the mod but it’s not installed. Just need the instructions

Thank you

I got it! Thank you

Awesome. Can’t wait to see more

Adding another $5 board and wiring to a rollover stops all the attract mode drama and slows him down so he's not freaking out under the glass..

Sounds like a cost-effective solution. I'm curious about the specifics, where'd you find the board, how it's wired, which roll over, etc. I love the mod but Grogu looks like he's on crack.

Shoot me a PM.. ill send you the info. Include your #.. easier to text pics. The difference is amazing. Mine only runs for 4 secs (I can decide the length of time), and moves naturally. Mine is triggered on the "I" in child by the rollover.

hi guys. what's the difference between the wiring harness or the full kit from lermods?? does the does ground had to be modified to move or the full kit is an actual replacement of the stock group on the mandalorian pinball??

cheers

The wiring harness is for those who want to buy and modify their own grogu. The full kit includes the harness and modified grogu, plug and play.

I started working on making six of my complete animated Grogu mods. This is an update from my previous post #246 and #256. I went ahead and created 3D printed mounting brackets to make things easier since I’m going to make a run or two of these. I currently have everything required to interface Grogu with the machine completed except for the Grogu’s internals at the moment. I also tweaked the microcontroller code a tad and made a couple changes in the wiring to make it cleaner and easier to install compared to my initial prototype configuration. There is no soldering required and everything is plug and play along with Grogu using the original factory mounting holes and screws in the back panel.

These are completely integrated and all modes are triggered by the machine. There is ‘Normal’ random effect mode when the left and/or right child LEDs are lit while the game is active just like originally triggering the actual toy with a touch of a hand. This mode is utilized in a controlled manner as to not overwork the doll for a longer life of the toy. Less is more in this case and makes the effects more special. There is a ‘Force’ mode that utilizes an interrupt when the magnet is triggered causing Grogu to queue start force mode by raising his right arm followed by getting sleepy and closing his eyes briefly, like in the show. When the machine is idle for approximately one minute, it will enter sleep mode and Grogu will close his eyes and do his sleep breathing effect with very slight head rocks for a few seconds followed staying still with his eyes shut after the game is over and sitting idle. He will remain this way until a new game is started or during attract modes generated in code when the machine sits unused for a while followed by falling asleep again. Grogu is always powered on with the machine and all modes completed in a controlled manner and there is no Grogu seizure looking effects like we see with other mods by forcing power on and off to the motor.

This has been very time consuming so far and haven’t even gotten to modifying the Grogu’s yet. I expect to have units available some time in July. No idea on price yet. I've had bad luck with overseas shipment recently and will probably limit these to the US and Canada.

Almost forgot to show that Grogu's necklace has glowing green eyes. I use a clear 3D printed LED holder bracket and black shroud to defuse the single LED light to both eyes.

I just installed mine. Is his head not supposed to touch the back box at all? I basically have him wedged in there.

His head should clear the top of the cabinet, but it is very close.

Awesome. I was able to get him in there better. Thanks for the heads up

I got sidetracked on other projects, but I'm slowly getting closer to the finish line and now have the Grogu internals modified minus final wiring. The tilt ball sensor bypass control lines are in place for sleep mode and all necessary cutting of internal frame and custom 3D printed bracket to allow moving the force arm effect to the left side is now complete. The mode trigger relay to bypass the capacitance touch to start effects is now mounted on a custom 3D printed bracket where the original speaker mounting holes were located. I still need to finish some internal wiring, modify the arms, and wire the necklaces. I might still tweak the code just a smidge more before final release.

20220623_074901 (resized).jpg

will these be for sale?

Yes, I’m making five of these to sell in the first round. The sixth one is mine and will also be used as a reference for future builds. I already have a list of people who expressed interest early on and they will get first dibs. Whenever I first release a new mod/product that is as extensive as this, either it be pinball or retro computer related, I only ship the first batch to buyers in the US first. Although I’ve never had issues (knock on wood) with any of my builds in the past fifteen plus years or so because I take my time and do lots of testing, I just do this to play it safe if the situation was to ever happen to make it easier to deal with. After the first round, it's open to everyone who's willing to pay for priority mail with insurance, which is not cheap outside the US.

I still don't have a price set yet. These things have proven to be extremely time consuming to build up. Everything from populating the controller PCBs, a bunch of wire, connectors, 3d printed parts, and extensive modifications to the Grogu toy to tie it all together. Every signal and sensor of the original Grogu PCB gets integrated for complete control by my microcontroller PCB controller. I do have the microcontroller code in the final release state and is absolutely amazing to see it in action in the machine. To do this, there are wiring harnesses that connect all the way to the flipper, child L&R LED boards, reed switch mounted near the magnet, inside Grogu, controller, and relay board. Grogu's internals are modified and rearranged with custom brackets to now have the right arm lift for force mode when the magnet fires, He'll fall asleep briefly after using the force and will fall asleep when inactive for over after a minute when the game is over. Child LEDs will start normal random effects in a time controlled manner for smooth integration and not to be overused. There is even an attract mode where he will wake up and do a random effect and fall back asleep when the machine sits idle long enough. The best thing is I have designed it so everything has a connector to tap signals needed and no soldering is needed anywhere.

Next up is to shorten Grogu's clothes and add the clips to the the necklace power lines and do final testing of each complete unit kit inside the machine.

Just wanted to share the job my head scenic artist did on my Grogu! Still waiting to figure out the best electronics solution for him, but he is looking amazing!

I own a theming company and we do props and set pieces for theme parks here in Central Florida, but primarily super high end themed rooms in homes. The artist that did this did a TON of Star Wars Galaxy’s Edge pieces too. I love it. Just need to figure out the best solution for electronics. My effects master could do it but he is always swamped with other projects, so I’ll most likely be buying something someone else has already developed. Hope everyone digs it!

That looks great. Awesome work, but wonder how that will look together with the more stylistic art from Randy. I always think that parts that look to realistic are not in line with the cartoon/drawing style that is on Mando. It is a thin line. That said I would love to see some of those super high end rooms. Always looking for inspiration.

are you aware of my version, my post on this page ?
I also made the version for the premium and LE, the scenario is the following, when the CHILD is activated, as soon as the ball is captured, grogu activates, he raises his arm closes his eyes to exercise the force, the ball is released and swirls, then when the magnet cuts, grogu starts moving again and returns to its initial position.
I have not yet had the opportunity to make a video with an LE.
this system is based on a program that we have coded, there is no Chinese or other timer, the triggering information is carried out using a magnetic sensor, we spent a lot of time to find the right one threshold so that the action is never missed and not disturbed by the surrounding magnetism.

I thought about that for about 3 seconds, but it instantly came down to cheap crappy single color toy vs realistic Grogu…no contest, no matter what the rest of the machine looks like. The Razor Crest isn’t highly stylized. Besides, the Grogu artwork on the machine is in my opinion its biggest failure so I want to make up for that as much as I can with a really awesome animated Grogu. But, that’s me.

First batch of units are sold out. I built up the electronics for the next batch and now it's time to start the wiring harnesses. Expecting more units in a few weeks if time permits.
Each one of my Grogu mods have 5 custom 3D printed brackets, harnesses have 34’ of wire and 20 connectors, custom microcontroller PCB, single relay PCB, dual relay PCB, reed switch assembly, all mounting brackets, and hardware. It is completely plug and play without any modifications to the pinball machine or soldering for the end user, significant internal modifications to the Grogu doll to use its right arm for Force mode, and 209 lines of code in the PIC microcontroller to make it all professionally integrated and of the highest quality.

These take days each to build and thoroughly test and I will not be able to offer these often. I slip these in rotation amongst other project and real life when I can.

More Grogu units (resized).jpg

I installed Tekmans mod earlier this week, replacing an earlier Grogu mod.

Honest take from a random guy who emailed Tekman out of the blue a while back expressing interest- this mod is *awesome*. Movements are so much more tightly controlled and not constantly in motion. He reacts to various events in the game, I can tell there was plenty of code with this. It just feels like he's now truly part of the pin. The moving arm is no longer trapped under the ramp, now relocated to the right side and free. Includes built in mounting hardware so no more movement of the entire body.

When the ball hits the magnet, his arm raises and eyes close. The attract mode is SO much better now, goes to "sleep" and briefly wakes up on occasion during attract.

I also want to compliment the nice job done on not just the relay and microcontroller box, but the entire harness and node board connectors perfectly match the Stern harness, his ID stickers even match Sterns yellow ID stickers. The whole thing is just pulled off extremely well.

Like the improvements you have made to the interaction with the game.
What is the price of your mod and availability?

Agreed, this mod is fantastic, just got mine going. “Less is more” is definitely true, the effect here is subtle and far more realistic. My only question is how long it should take for the Force move to kick in after the magnet turns on? I feel like this takes several (4-5?) seconds, often even after I’ve drained (I’m not good

Glad you’re liking it. The force mode effect uses an interrupt to queue the effect next in line. So, if there is no other effect happening at the time, it will start right away. Right away being my interface immediately configuring the proper configuration for the factory controller inside Grogu’s head to start. So there is about 1.5 seconds (triggering three relays in proper sequence and timing for force effect) for that to be accomplish before it starts the factory force mode sequence. If a child normal mode effect was already in progress, the force mode interrupt will speed up the current mode as fast as possible, while still playing nice as not to not confuse the factory controller inside Grogu’s head before force configuration and mode can begin. This is what you must be seeing for it to take over 2 seconds to start force mode. You are having some serious fast ball times if Grogu can't keep up.

Thanks for the explanation! I like to think about what’s going on behind the scenes here, clearly a lot of thinking and effort. I think I was hoping he might lift his arm while the ball was still up in that area magnetized but makes sense that it needs to clear out a queue first.

Makes me want to learn more about to do this kind of tinkering. Great work, again!

Thanks. I'll offer some more detail that might help explain what is going on when modes happen and the restrictions to work with.

It would be nice if that kind of reaction was possible, but it just isn't. Only if the actual Mando code was changed to hold the ball at the magnet for a period of time would allow that to work. Mando code just doesn't have a reason to hold the ball, unlike other games that need to fully complete some effect that do.

In the back of an unaltered factory Grogu, there is a mode switch (normal-off-force) that needs to be flipped to do force and normal mode. In development, it was quickly discovered that it wasn't possible to force opposite modes on each other because the factory controller inside Grogu's head can't handle that and can even lock up. So, there is sweet spot in my external controller code if you will that makes all these things happen safely. For example, this is the reason you can't abruptly switch to force when the magnet was activated while normal mode is still currently in effect and why force had to be placed in queue next. With that said, my controller still knows if that situation has occurred and will speed up the normal mode timer to finish the effect sooner to safely get to force as soon as it can. When normal mode is not in effect and the magnet is activated, you are seeing the fastest scenario for the doll to start force mode and is very close to what the factory doll can do when switched to force mode and then touching the head. It's just that the doll's factory controller has it doing stuff before getting to raising it's arm and makes the process seem longer than ideal. So given the circumstances, the force effect is the best effort for what we have to work with.

Following this thread. Making me want a Mandalorian Pro even more right now....

Grogu Ultimate batch 3 has begun.

Grogu Ultimate Batch 3 has begun (resized).jpg

Batch 3 is getting closer to the finish line..

third batch closer (resized).jpg

I have a few Grogu Ultimate units ready to ship. https://lundyelectronics.com/product/grogu-ultimate/

I installed Tekman's Ultimate Grogu mod in my Mando this weekend.

A great bit of kit and built so well. From the instructions to the wiring and even the way it was packed is meticulous.
I can see Tekman really takes pride in his work and has developed something special for the Mando fans.

The kids loved him come to life and the old Grogu has found his place as a topper. (At least until I find US$2000)

Well done and thanks again.

How was the install? Seems pretty straight forward after reading the instructions. What’s your thought on how it works?

Yes, very straight forward as all the wiring looms are clearly labelled, connectors make it hard to go wrong and the instructions are clear.

The bracket on his back is custom made so he slips right into the correct spot. His clothes needed a little adjustment to clear the moving parts (head and arm).

You will need to predrill 3 small screw holes for the relay and reed switch. I got the position of the reed switch right the first time but can see how this could need adjustment to get right. The instructions clarify this.

Be careful with the flipper alligator clip contact. My switch contacts were very close and I paid particular attention that it was in the right spot so any large movements of the pin wouldn't short the switch circuit.

I took my time making sure everything looked nice with the zip ties and after testing I would say it will take you about 90 minutes.

He works well compared to some of the other designs on the market I've researched, however as mentioned earlier in the thread there is some delay with the force mode and magnet due to limitations with the Grogu robotics?

I’m glad your install went well and thank you for sharing your experience with the group!

I wish Grogu could be faster to react to the magnet force. I’m using an interrupt in the microcontroller and the magnet is being sensed immediately. Unfortunately, there are four things at play that doesn’t allow Grogu to start the arm movement the instant the magnet is fired.

1 – The internal factory controller inside Grogu’s head isn’t designed to abruptly change modes. In the back of the toy, there is a switch to select normal or force mode effects, with off in between. My controller has to play nice with the factory controller’s limitations in order to safely switch modes via relays, including the sleep sensor and touch sensor both requiring a dedicated relay . If I switch modes too quickly, the internal controller will error out and lock up. There’s even more to it than that, but this is the short version.

2 – I’m forced to queue the start of force mode in the event a normal mode effect was already in effect and then have to speed the current mode up as fast as possible, but not too fast in order for the toy to safely switch to force mode.

3 – The internal factory controller has Grogu briefly moves his head a bit with a small delay before raising the arm. This just amplifies the overall delay to get the mode started and is out of my control.

4 – The biggest limitation of all. Unlike many games that will hold the ball at the magnet to perform some sort of effect, the Mando magnet doesn’t hold the ball and I don’t have the luxury of being able to take advantage of the extra time for the best effect.

If anyone is interested, I still have two units available on my website at lundyelectronics.com.

One unit left. I should have more in mid December time frame. Visit https://lundyelectronics.com/product-category/pinball/

Highly recommended!!! Install took me less than an hour.

This batch is now sold out. I'll have more in December.
