Picture of Interactive LED Beer Pong Table

Create your own Interactive LED Beer Pong Table!

This instructable will guide you through all of the steps to in order to create a one-of-a-kind beer pong table complete with cup detecting RGB pods, automatic ball washers, a 32x12 ping pong ball LED grid, side LED rings for spectators and an RF interface to communicate wirelessly with a PC! It will teach you everything from theory of operation to modifying the table to suit your needs. First, I will take you through the modification and wiring of the table before we dive into the software side of things.

The toughest part about this project is just getting it started. There is a lot of prepping and labour to do before you can get anything real exciting working. However, if you can stick it out until you get the 32x12 LED grid in place, you will do just fine. Once you get up to that point, you can really start to see the potential for the table and it makes working on it a lot more enjoyable. I worked on this table on and off over the course of one year. If I were to build another one and had a set schedule of 8-hours per day to work on it, I could easily finish it within one week. The majority of the time that I spent on this project went into prototyping, development and writing the software rather than actually assembling the project.

Now come and take a tour with me through this Instructable and let us find out if you are up for the challenge!

Daily Planet on the Discovery Channel did a short segment with me on this project. If you are interested in seeing it, check it out here .


I have a few PCB kits ready to go for the improved Interactive LED Beer Pong Table. I have chosen to create a new Instructable for that beer pong table which is where I will post my site URL and the shop where the kit can be purchased. The new Instructable is needed, as it will show the full potential of the new table and how all of the features work. I have currently been asked to ship a table out to Daily Planet for them to have for a few days, so that is the table that I will be using in my new Instructable!

Will the new improved table still be based off the wooden table or your silicone one ? And also I'm gonna end up buying the pre made pcbs anyway but is there any way I can like pre order them or how long will it take to make a new set if I don't get them before they sell out right away? I was hoping to finish table before Christmas and sorry I don't have a paypal only a visa debit

Do you have a set of the boards available to purchase?

Regax (author)  partyhouse6 days ago

Yes. I have to finish the checkout portion of my site but if you want a set now for the new revision of the table it is $78.99 for all of the required PCBs (PM me for more details). We can just manually do the transaction over Paypal or you can wait until I have completed the site with a write-up and instructions to build the new version.

I would like to buy the new revision completed circuit boards if you have a full set available and can process the transaction through Paypal. Thank you

Yes, I would be interested in getting a set for the new version of the table and could process the transaction through Paypal.

This is an awesome project that I am extremely interested in trying out. Just a few questions though. How durable is this? I live in a high traffic house, is this table very fragile? If someone spills a cup will it fry the entire thing? would you have any suggestions for making it more durable if you see any weak points (durability wise) in the design as it stands above?

Also, can one choose not to include the ball washer to save some money? Would you recommend it, or is it pretty much essential?

Do you pre make the whole thing or is it all seperate? How much is it for the whole thing pre made?

I am interested in buying a table built and ready to go... I wouldn't mind some simple assembly (like legs lol) but preferably with no wires to solder and nothing to build, cut, etc. You can e-mail me at


where did the get the motors and ducts for the ball washers? iv found the fan ducts on ebay, however there seems to be various motors when you search for the "24mm 13000 rmp 12v electric motor" if you by chance have the website you ordered the parts from that would be handy, thank you for your time.

Regax (author)  BigCountryBeerPong11 days ago

It looks like the listing has been taken down. You can pretty much use any motor with high RPM's if you're driving it with a higher amperage transistor or MOSFET. I had to be careful as any motor that drew more than 500mA was burning out the ULN2803 transistor array. So if you're just making the ball washers, just use any high RPM motor and modify the circuit to be able to power the new motor. If you're using my design with the ULN2803A transistor array, you'll have to find a low current high RPM motor. Careful though, on eBay a lot of the motors pull more current than what their specs say. It took me quite awhile to find those motors that worked :-/

When you posting link for new site and instructable
Regax (author)  cgranger11 days ago

Soon here. I have the table pretty much ready to go now, just need to attach the legs and polish up the revised code. This new one is getting shipped off to Daily Planet for a few days, so I'll do the write-up then. Here are a few photos of it. The last photo is a photo of the underside for the beer pong table in this Instructable.The new one is a little less messy under the hood ;)

Hello pcb is at once the components soldered ? And what cost . 1 x set. Or do you sell full table ? How much cost
Regax (author)  14_Tom15 days ago

The first kit is the PCB only kit which comes with 22 PCBs and costs $78.99. No components are soldered on the PCB only kit. For the full table, you would have to send me an email but it is really expensive with the shipping.


cgranger17 days ago
Can you shoot me an email when you start selling kits I would like to purchase one
Regax (author)  cgranger15 days ago

You bet. I have 5 full sets to go, which doesn't seem like very many, but that's a total of 105 PCBs actually. So I have to sell them off first then order a larger batch. I actually have 10 Master PCBs right now but I only have 5 sets of RGB pods.

The PCB kit comes with a Master PCB (controls everything), 20 RGB pods and a 50-pin Breakout PCB for the LED grid. A total of 22 PCBs. I will be posting full documentation from the source code, to the BOM and where to purchase parts, and all of the features that it can handle.

Here is a photo of the PCB kit that I will be selling (I have blocked out the URL on the silkscreen for now).

First of all, thanks for the nice instruction. Don't want to know how much time it cost you to create it...However I decided to follow it and create a beer pong table on my own (one which can be folded in the middle in order to save place when it is not in use).

Now i am running into small issues while assembling the Master Control platine. I used the gerber files for v2.1 but it seems to me that the are some differents between v2.1 and the screenshot of the schematics Master Control "Document number 001".

I have uploaded two screenshots (each for the bottom and the top). I marked the components. On the top side, there it is R11, a solder pet which is not labled, and 5 "holes". On the bottom side it is only R12. Could you please help me? Is it possible that there are any schematics for the Master Control PCB v2.1? Thanks in advance.

BTW: Realy looking forward to get the led grid light up :)

Regax (author)  rookiii2 months ago

It looks like I had uploaded the schematic of the prior version. I had done some touchups, getting rid of an unneeded variable resistor, adding pull-up resistors for the TLC5940, etc.

The proper schematic has been uploaded in PNG and PDF format now. Anyways, the bottom side resistor that you have circled is R10, which is a 10k ohm value. I had replaced a potentiometer there with a fixed resistor.

As for the top side, the 5 holes are for the LM2576-3.3 switching voltage regulator. Make sure to have proper orientation of the pins, the first time I soldered it in I had actually reversed the chip. The center pads closest to the PIC are actually just extra SMD pads that are connected to AN5 & AN4, I broke them out from the PIC in case I needed to add any extra "features" to the table. Lastly, R11 on the top side is just a 10k pull-up resistor for the TLC5940. This ensures that all outputs are blanked on start-up and until the PIC takes control of the pin.

Thanks for pointing out that issue!

Thanks for your reply. I assembled my PCB accordingly. After connecting both PCUs, any component begins to squeeze (actually i don't know which component causes this but i guess its the inductor. I disconnect the PCUs and checked the heat of all components. I noticed that L2, D5 and the LM2566 got really hot. Do you have any idea what might be the issue here? Do you have any clues what i can check in order to figure out the problem? I have attached my PCB...

Regax (author)  rookiii2 months ago

I know that my first try I had the LM2576-3.3 flipped around and it was causing issues. Take a multi-meter and put it on continuity mode, cross-referencing each pin with the schematic and check to see if anything is shorting. Switching power supplies can cause a bit of high-pitched noise (mine didn't however), but it really seems in your case that something may be shorting or maybe something is soldered in the wrong orientation.

Give that a shot and let me know if it helps! Cheers.

Finally I found the issue. Indeed there was a short on the master PCB. Now i am running into another issue regarding the LED Grid. In order to test functionality, i turn on all leds in the main application. The LEDs connected to HT1632 light up as expected but the LEDs connected to the second HT1632 do not. I measured the outputs which are passed to the anode of the grid and for LED driver 1, they are all at ~4.87 V but for the second one they are only 2.44. I also measured the VCC and of the second driver but it seems to be o.k. (~5 V). Do you have any idea what goes wrong here? Maybe any idea what i can do to investigate this issue? Thanks in advance.

Regax (author)  rookiii1 month ago

That seems like a tricky one. I would first take my multimeter and check across each row/column to make sure that there is no short in the LED grid. Next, I would check the orientation, making sure that I installed the HT1632C the right way on the PCB. Seeing as it is on the bottom of the PCB, you have to pay close attention as to which pad is pin #1, seeing as when you are working on the bottom of the PCB it is a flipped view from the top view of the board for the silkscreen.

If all of that is correct, I would then test each pin on the HT1632C with the next pin beside it to see if I could find any shorts there. Lastly, I would probably try a new HT1632C chip, taking the old one out and soldering in a new one in case the first was faulty.

You could even use a logic analyzer (if you have one) to verify that data is shifting out of the first HT1632C properly before going into the second one. Then check how the data is shifting out of the second one after you have verified the first one. I don't think this is the issue though, it seems that something is just connected up wrong on the second HT1632C. Let me know if any of that helps!

rookiii Regax1 month ago

Thank you for the input. I already tried out the most things and if i switch the cables connected to HT1632C #1 and HT1632C#2 the LED's which did not light up on #2, now do. The other which worked on #1 well, does not light up on #2. So there is definitely some error regarding the connection of the HT1632C#2 chip or a faulty / damaged unit. I expel connection issues by checking each pin and they are all connected / wired correctly. Even the signals look very good to me. So i guess it is the HT1632C driver itself...I already ordered some new ones but i only found some on ebay china which has ~6 weeks delivery time :/ But no problem since i have to create the 20 RGB Pods... :D

rookiii rookiii1 month ago

The new led drivers have been delivered earlier. I soldered a new one on slot #2 but exactly the same behavior. I programmed a while (1) which turns on all led's. I have connected no led's to the controller in order to exclude wire issues on the table itself. I measured the voltage on the output pins which will be connected to the anode pins of the led's and for driver #1 the voltage is 4,8 while the for driver #2 the voltage is 2,4. So all rows of #1 are 4,8 while all rows of #2 are 2,4. I checked all pins for shorts but all pins are connected correctly. General communication works also fine as both drivers change the state if i turn on / off all led's. Now i checked all VDD/VCC/GND pins as it seems to me that #2 receivces to less voltage but again everything fine. The VDD pins of #2 are at 4,8V (exactly like for the #1 driver). The GND pins are at 0 V. I have no more idea what i can check and i am wondering that the output of #2 is exactly 50% of the output of #1. Do anybody have any idea / point for this strange behavior?

Short: Communication works fine. Supply voltage is ~5V for both drivers. Output of #1 is 5V (as expected). Output of #2 is 2.5V.

Regax (author)  rookiii19 days ago

Sorry for such a late reply here. I saw this when I was working then it slipped my mind. I really have no idea why it is doing that. The only thing that I could recommend if trying to make the RJ45 patch cable as short as possible between the HT1632C Control PCB and the Master PCB. But even then, if one isn't working because of that, neither should the other. On page 16 of the HT1632C datasheet ( it shows how to cascade these chips. As long as the OSC and SYNC pins are connected to each other across each chip, it should be working. You wouldn't happen to have a logic analyzer to be able to view the data that is being sent to the 2nd HT1632C would you?

hey I'm Polish I am in the initial stage of the work, I question whether you are up for sale all ready PCB or the whole album? I would like to make it for the holidays to do everything With greetings from Polish
Regax (author)  jo43ght25 days ago

I currently have 5 full sets of PCBs ready to be sold. I will update the post in the Intro on Dec 1st with my website and where they can be purchased. Depending on how quickly I sell those sets, I will be ordering another batch with a much larger quantity.

how much does it cost to make one of these tables? I want to know before I get started. can someone atleast provide me with a range.

Regax (author)  davidapye1 month ago

This cost around $500 for all of the parts and equipment, but the amount of labor/development put into it was quite high. I am set to release a PCB only kit which consists of all the needed PCBs to make a table exactly with this, plus more! (See Intro update for other features).

The PCBs are a pain to make, but in the new version there is only one main PCB whereas there is 4 main PCBs in this Instructable. Along with that single PCB, in the kit will be twenty RGB pod PCBs and a simple 50-pin breakout connector for connecting the LED grid.

I plan to sell the kit of 22 total PCBs for around the $80 mark. It would be much cheaper if the RGB pods didn't have to be PCBs, as the large quantity of them is what drives up the price. I don't have the exact price and BOM for the finalized revision of the table, but it will probably be around $60 - $100 worth of parts.

After that, you just need a lexan or acrylic sheet and a lot of time to wire up the LED grid! I have been working on a version of the LED grid which is just a silicone mat with the grid and LEDs inside of it (allowing it to be shipped). I will post pictures in the next update.

I am very interested in buying pre-made components to this or just an entire table! Please let me know if that is possible at all. :D

Regax (author)  Parving2 months ago

It definitely is possible! I will post another update in the intro soon. I am still shooting for having the PCB kits available for Dec 1st. As of right now, all is on track.

kidkardiac2 months ago

do you have an estimate of how much this table would cost? I'm also interested in purchasing!

Regax (author)  kidkardiac2 months ago

I do not have an estimate right at the moment as I have not finalized the table design yet. I want to house everything in an aluminum table as it is lighter than wood and more durable.

backattack2 months ago

I would also be interested in knowing what the kit would include and how to buy them when available.

Regax (author)  backattack2 months ago

I intend to sell 3 kit versions. A PCB only version, a PCB with all included electronic components unassembled version and a fully assembled PCB version. There are a total of 21 PCBs for this project, 20 of them being the RGB pods. I am working on a website where I will be able to post updates and improvements for this project, as I do not want to mix it with this version of the beer pong table in this Instructable as I have made some changes to the new design. I will post a link in the intro to the new design once I have the site up and running.
