@@LegoCloud Thanks for the compliments! I tried SO MANY DIFFERENT THINGS to try to limit scoring to 1 or 2 sensors but nothing worked. Once I accepted the fact that I couldn’t(or just didn’t try hard enough) I had to go with separate sensors. I did try to make the balls press down the touch sensors but they were, in fact, too heavy.

@@mj_bricks Thank you! I put in the extra time and effort to make it as close to the original Skee Ball game as possible, even on the inside!

@@elitelegostudios Thanks for the compliment! I put extra effort into this one to make it as close to the ‘real’ arcade game as possible… even internally!

@@ozziegerff It’s a regulated linear power supply, so it’s relatively large for how much power it can output. The yellow thing on the bottom is a toroidal transformer with the secondary removed and several turns of 10AWG wire to give me around 10VAC. When rectified, that gives about 14VDC. The board has a full bridge rectifier with an adjustable 5A linear regulator(LM338K), so I tuned it to 9V which EV3 needs. I may not need 5A, but notice how there are 6 slots on the pressure connector, 2 wires for each EV3, so it can run 3 EV3s simultaneously. Considering a completely stalled EV3 L motor can pull more than 1.5A, I think 5A is just right. I made a video on this topic a while back and discussed switching vs linear power supplies, but totally neglected regulated linear power supplies. These are ideal for this application as linear regulators have the most stable output voltage out of all these power supply types. The only downside really is bulkiness and excess heat generation. Anyway, thank you for the compliment!

@LegoTechnicsRule fun fact i found out is that the circuitry for the ev3 is regulated but the motors aren't. So you can safely give it 12v and it will work fine, but the motors will run faster and stronger, vice versa with undervolting. I wouldn't push it past 12v though. The cpu regulator is probably rated for 3-15v so it is safe to supply in that range. You may think this is crazy and dangerous, but the batteries that you put in them can be as high as 1.85v and as low as 1v, so the operational range has to be large for both the cpu and the motor. I would not run it at 12v under high load constantly (or risk overheating motors, but if you need short bursts of power this is a great option. I am using a 3-12v @5A power supply, it's perfect for this, I wired a DC jack into my ev3, where I can still use batteries if I want. Pretty easy to do and without all the exposed electronics. www.amazon.com/Universal-Switching-Adjustable-100-240V-Converter/dp/B083GG2H6R

@@ozziegerff You gave me the opportunity to nerd out on electronics, so that’s just what I’m gonna do haha. The circuitry for the EV3 is indeed regulated… with a linear regulator. Linear regulators have a property known as PSRR(Power Supply Ripple Rejection). In short, it’s the ability for the linear regulator to filter out ripple in the input voltage. Linear regulators get worse at doing this as the frequency of the ripple increases. A linear regulated power supply only has to filter out 100 or 120Hz ripple from the full bridge rectifier and given the input voltage is higher than the linear regulator’s dropout voltage, no problem! With switching power supplies such as the one you linked, there is significantly higher frequency ripple(several kHz to 1MHz) that gets worse with load. As stated earlier, linear regulators are less effective at rejecting higher frequency ripple and might pass some of it on to the load. This is bad because unstable voltage, especially to a CPU, can lead to instability and crashes. (This is precisely why I used a linear regulated power supply for my EV3s) Also, using a higher input voltage leads to more heat being generated in the linear regulator according to the linear regulator power loss equation, Vin - Vout * Current = power loss in watts. Thus keeping the input voltage as close to the output voltage plus the linear regulator’s dropout voltage is ideal. Regarding the motors, they are indeed fed the raw battery voltage, but the speed is regulated by changing the duty cycle(PWM). So I suppose you’re correct in saying that for a given duty cycle, the motors would be more powerful.

@@LegoTechnicsRule however considering the fact of the cpus low power draw, plus the fact that these are off the shelf components made for all environments and the ev3 had a proper ac power pack, means that this this effect will likely have little consequences in the long run and it is overall not a problem, infact the capacitors on the board will likely fail long before the regulator fails from stress in this situation.

@@ozziegerff I may just have had a crappy switching power supply. I was running two EV3s off of one 9V 2A power supply and whenever a motor turned on one or both EV3s would reset. A quick poke with an oscilloscope showed a 50kHz 1V peak to peak ripple at 9V under just a 500mA load. That’s absolutely terrible! To avoid having anymore issues, I just immediately went with the big guns to be done with it: regulated linear. You don’t happen to have access to an oscilloscope? I would be interested in seeing the ripple with your particular power supply. Edit: EV3 draws 100mA at idle. Thats almost a whole watt! That’s a decent bit of power for a battery operated device.

@@politicallyinaccuratetoast4757 It all comes down to how the motor is wound. I don’t know the math behind it, but DC motor speed at a given voltage is determined mainly by number of turns of wire around the armature. (Number of poles also plays a role.) These motors must have less turns than the original ones. Less turns means faster and stronger but also shorter lifespan as more heat is generated and the higher RPM will wear out the brushes/bearings/gears faster.

Lol thanks for the kind words!

I wonder who this is… Anyway the instructions video is currently uploading. Maximum players for 7 cards is 7 players because 7 x 7 = 49, which is less than 52. If the user tried to go and set it to 8 cards, it would automatically decrement it back down to 7. This same logic can be applied to 5 cards, maximum of 10 players.

Yes. Yes it does.

A LEGO washing machine? That’s legendary lol. Please let me know here if you make a video about it, I would be very interested in what you came up with.

AA batteries are expensive, and EV3 is not a low-power platform. I thought I’d make it so the light switch can still be operable with the EV3 disabled all while still being attached to the light switch.

@@LegoTechnicsRule then use powered up

@@luigikoopa8771 Powered Up would have actually been very good for this! The problem with using powered up for this is that it’s not as widespread as EV3 and I originally planned this project to come with a tutorial. That would kinda screw lots of people who wanted to build this for themselves.

For that we need a dimmable bulb as well as a dimmer switch.

You can find them on bricklink or eBay. They are known as RCX to NXT converter cables.

they have that in the us

@@Idiotgaming-ny8ql oh the plate is squer

If your switch has some kind of screws I’m sure you could rig something up to attach. After that and considering you have an EV3, use good ol’ creativity to do make something to twist the knob!

I would like to believe I’ve come a long way. Any encouragement helps!

I actually completely agree with this. Lego switched to an “environmentally friendly” plastic a few years ago and it’s way more flimsy than the good ol fashion ABS they used to use. Lego has become more of a modern greedy corporation compared to how they were.

I don’t for this machine. The reason is that it’s just so big and instructions for something like it would be very unconventional to make.

I’m still here lol

just that

You know what, I’m not quite sure. However what I do know is that they are extremely useful and that’s most of what we care about!
