Updates: 1. Chris confirmed that he was on the Lotus account in their discord server, people pointed that he was not supposed to be but eventually just accepted it as 'okay well whatever'. Lotus customers are on a completely different level 2. He says I'm wrong about the delays because I'm no business owner 3. Honestly, just see this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--ZW_1fQzxs8.html NOTES AND FAQ HERE, EXPAND PLS Since I've pointed out some of the dumb mistakes Chris has done, it's likely that the lotus3k can be fixed if they actually paid attention (nevermind, they don't even wanna watch this video). So if the 3k suddenly is announced to be working, you know I helped them with that ;) Also if you're a customer who can't get a refund, honestly your best bet at this point is to try your luck calling your bank and asking them to forcibly reverse the transaction. Q: What song did you use at X? Intro: Laur - Viyella's Nightmare Gameplay: HiTECH NINJA - Modelista Second half: Akira Complex - Ether Strike ('Divine Mercy' Extended) Q: How much did this cost? Way too much, really not a project I'd recommend anyone on a budget at all. It was over $200+ for 5 of these (though I can only make 4, I only bought 4 MCUs). Low quantity units are expensive, and I had to buy the minimum amount for each component. I have 100 resistors and 1000 screws, I don't know what to do with them omg Other more technical jargon: I'm still very new to all of this. I wouldn't be surprised if my PCB design sucks still, but I'll keep learning in the future. Next time I wanna make a mini-IIDX con! Being open to learning is really important when it comes to making your own things (but honestly this is daunting as hell because you're basically learning stuff engineer students are being taught in school yourself) If you guys would like to make your own keypads but have no experience with any of these, I HIGHLY recommend buying a breadboard, parts and an arduino micro to start out. Jumping right into PCB designing is actually not a good idea, I did it anyway since qmk is an easy cop out for custom keyboards if you follow their guide and only plan to do that. I should have done this on a breadboard first and etc etc etc because later on when I tried learning some AVR programming, it was quite the nightmare to troubleshoot since... well, the PCB is already made, it doesn't have ICSP pins either. Though I do have a skeleton and extremely basic firmware written outside of qmk with the generous help of Thomazzz3, Xeal, lame and mon! Thank you guys so much for being patient with me. It's not mentioned anywhere in the video but wow, this is really fun and I want to try making more things than just 3 keys on a PCB.
im so amused at how similar our experiences have been- i also had to scrap a whole order bc i got overconfident and ordered a design without testing it on a breadboard AND i just skipped adding in debug pins. never again lmao
imagine running a company that makes keyboards/keypads, and then an enthusiast makes what you've been trying to do for a while in a month you're amazing keep it up
The guy running lotuspro isn't trying to run a legit business. He has a history of starting businesses and not delivering and pocketing the money. He burned down his summitcables company by not delivering cables and using those funds elsewhere, now he's doing it with lotus. He will most likely abandon lotus in time and make it seem like it's our fault somehow or the manufacturers. Then he will turn around and start a new business under a new name and exit scam again. That's his real goal.
@@incongruous4 And nobody managed to get his real name or at least something to keep track of him and the shit he's doing? I'm sure it's just a matter of time
my dad's really cool, I honestly think he's the reason I became such a tinkerer with things, because he had always been like that around me. Really explains all the random useful tools in my home LOL
I ordered the 3 key pad and it was really upsetting on how it was really bad service and really bad support. I dmed one of the employees for lotus and they told me to ask the creator of lotus about it. I asked nicely about it and I was immediately insulted,sweared at and even got made fun of my Autism because I mentioned it in the server before! He ended up giving me a refund and I left the server having a bad taste in my mouth. I am glad people are exposing the company and I hope no one else gets the experience I had!
@@rrranes as someone with asd I absolutely concur. I was looking into 3key pads for when i play osu a while back and had lotus top of list so glad that I had held off after seeing this video among other things. @Dromero VA dont let the haters and ignorant idiots like that creep get ya down. Some of the best geniuses were neurodivergent! Gotta keep the faith mate and let the assholes who attack you burn like that fella obviously has.
i am an electrical engineering student, i'm only in 2nd semester but still got physical pain during some parts of the "out of spite" section. this guy claims to be an actual engineer yet knows less about the basics of how electrical circuits work than 5th graders visiting uni on open-door day
I got here via algorithm and don’t play osu! or have any idea what these are, but I found this so entertaining and awesome! It was an incredible and professional end product. SO satisfying to see you make this compared to shady companies that take decades to return to investors. LOVE TO SEE IT ❤️
Same. I just know basic electronics repair but I know to put my multimeter into DC mode. If I actually use AC that probably means I'm poking at "spicy" stuff that I have no business playing around with :D
Oh noooooo, not "miss-information"! 😂. The absolute difference in your energy/tone in this video compared to the original one you made a few months ago is hilarious. Petty-Taku is wild lmao!
well does your keypad have 10000hz polling, -1ms response times AND gives the player infinite stamina? on a real note its impressive you learned more than everything he knew in about a month AND actually put it together. makes me wanna give it a shot too 😭
Having an engineering degree, and being good at engineering, are two different things. You can be an engineer even with low IQ, and mediocre intellect, so all those claims about being an engineer of all those things can be just an overblown fluff.
11:02 The 'fuse accepting voltage' just made me go, 'Huh???' Like, before I even went to college for electrical engineering diploma, I know what fuses are, and it's main purpose. 11:42 This part is just baffling, and embarrassing for him. You don't deserve to claim to be an electrical engineer if you have no idea the basics of if using a multimeter, and also the difference between DC and AC
Also not how his probes are melted, the last time I so much a blew a DMM fuse was in my vocational High School EE shop. Some people really shouldn't be messing with this stuff.
Bruh I’m 15 and know the difference between DC and AC. DC is a direct current, meaning alll the electrons flow in one direction. Ac is an alternating current meaning the direction of the electrons is constantly switching
I've literally no electrical knowledge as I tend to wrench away at the big stuff while the smarter guy does the expensive parts and even I know fuse takes electricity then goes boom so nothing else goes boom. As for ac DC, they're a good band. Aside from that I don't own a multimeter...
This video is great! It goes into the basics of product design, points out issues that may come up when designing something like this, and shows clearly that something as simple as a keypad is possible even for a novice to design (I mean it's simple enough that it would make for a good project for an introduction class on electrical engineering.) I know that you're probably not interested in selling this, but I'd be willing to bet if you were to make and sell them in batches you could probably make decent money doing so. Regardless, good work on the video!
holy crap this looks and sounds infinitely better than the lotus3k. so much respect for you, especially since i only found this video because chris was being an unprofessional asshole for the 10,000,000th time. being in their discord server is literally just an advertisement for how excellent your content is
So, I have been both playing osu! for a while (4 years) and been doing electronics as a hobby for a long while (12+ years, not too sure since I started as a kid) and I've been watching from the sidelines as Lotus (mainly just Chris) has basically dug their own grave, hopped in, and dug their own grave again, every time they post an update. Seeing the video that undefined posted was just, from my perspective, so bad. It hurt to know that people were paying for something that, as you've proven, is not hard to make, and there's already enough resources out there, for FREE, to help anyone to make keypads successfully. It's almost like Lotus just wanted to make a rug-pull for money after they get fame! Anyways, enough about Lotus, now about my thoughts of your keypad! 1. The PCB layout and routing is really good and looks basically professional! I was honestly impressed with that alone while I was watching. 2. Your soldering was alright, but you likely weren't using the right solder and flux. If you are going to manufacture keypads in any quantity, get a stencil, solder paste, and a hot air station for SMD parts, and solder the bigger parts by hand with plenty of flux and good solder. You should always have smooth solder blobs, and if it isn't smooth, something's not right. 3. Not really a thought about your keypad, but if AutoCAD is giving you issues, exporting or money wise, there are plenty of free CAD alternatives like FreeCAD, OpenSCAD, etc. 4. How you change colors on your keypad is almost perfect, I was blown away to see that you used hue and saturation instead of preset colors like most things I've seen use. Adding a value control for the brightness (the V in HSV) would make it absolutely perfect, though. That's all of my thoughts in places where I feel like I can comment, since I know nothing about acrylic manufacturing. Over all, you did a pretty good job! If you did sell these, I'd definitely buy one, especially knowing that I'll be supporting you and that it was also fueled from spite against Lotus lmao
1. Aw, thank you! I think they could be better imo, I still have space to improve. But I'm glad they were presentable at the very least LOL 2. Ah, I didn't want to go with a stencil, hot air gun and solder paste since I would putting even more money into equipment for this. Maybe in the future if I do a lot of prototyping like this! Kinda wish my soldering iron was using a flat tip instead of pointed *sigh* 3. God thank you, I was gonna go get coreldraw instead of anything free 4. Ah, I take no credit for that, the ease of changing hue and saturation is because of qmk. From ground up, firmware writing would be a lot more impressive. There's actually a brightness setting but it wasn't shown in the video omg
Your story reminds me of a thing that happened to my mom and I. Granted, this was with baking. I'm gluten free, which makes getting pastries difficult. We managed to find a bakery that made gluten free pies, and claimed they spent four years perfecting the recipe. Honestly, it tasted horrible. So, my mom and I tried a recipe of our own. First shot. It tasted great. You with your keypad and me with my pies... showing 'em that you can do it, no matter what!
I've been dreaming of making a mini Pop'n Music controller and this has got me VERRRRY tempted. Thank you and congrats on the absolutely world-class spite!
you should join the cons&stuff server for something like this! you really don't need to make an entire PCB for a homemade controller, even bigger officially sold controllers are big buttons wired to a single main board. Get yourself an arduino and go ham
I barely understood a tenth of how you made this keypad, and this makes me respect you a lot. I always appreciate hearing people talking about their crafts, and appreciate even more those who work hard to learn new things. Good job!
Good on you for doing this, if nothing else to but show how utterly ridiculous Chris/rora/kdefs/Summit/Rose Cables/Lotus Pro and his claims are. It’s frustrating that he was able to take so many people in multiple communities for a ride. Again. That being said, it’s also such an awesome feeling when a project that you worked so many hours on comes together.
Yeah, it really sucks that iirc there's about 80 lotus3k customers and 5 lotus87 customers. They're not going to get their product. And they're still trying to fulfill hundreds of 2k orders too. Anyway, yeah! It was jaw dropping when I saw my PCB worked, I had absolutely zero faith in myself lmao
Does this project sound like something I would ever do? Nope. But “I woke up today and chose violence” was such a powerful opener that I couldn’t not watch
For someone who has lost touch in electrical engineering (which is me), yeah, you are impressive in making your DIY stuff. How much (money) did it take to make this thing? **MISSINFORMATION**
god, the prices were insane because I had to buy in batches due to minimum orders. I have 100 resistors and 1000 screws I have NO idea what to do with them. But overall this project costed me about $200+? for 5 units (though I didn't buy enough MCUs, just 4, so I can only make 4 keypads)
@@heroslippy6666 I was planning on holding a patreon giveaway actually... Although two of my PCBs are dead (unfortunate accidents with the USB port) and one was given to tzechi. I still have one extra PCB left but no MCU to use. I'll try desoldering the chip off the broken PCBs but no promises that it'd work, I tried desoldering one other time and it broke pins off the chip rendering it useless omg
Thank you once again for being the hero the community needs. You've now inadvertently inspired me and probably a few others to try making their own keypads as well
Honestly, I can relate to the motivation xD I wanted to get into custom keyboards a bit over a year ago and was honestly terrified of spending +$100 on something I might not even like, so I took a risk and made my own from scratch, i.e. an arduino, key switches salvaged from an e-waste board (I got 105 cheap-but-okay cherryMX clones for $15, that's not terrible), and handwired… it's not pretty, but the materials were less than $30 and it was honestly far less complicated than I feared. I'm thinking of getting a real PCB for my next real attempt, but just as a starting point I'd say if anybody out there wants to give it a try, it's really not rocket science, I mean if I can do it then it can't be impossible xD Then again, looking at Lotus… 😬 Point is, I think it's cool that you're showing off that keyboard design isn't, like, a holy grail that only a select few can achieve, and while it may feel even more crappy now knowing how (comparatively) simple the process _can_ be and Lotus _still_ managed to fuck it up, maybe a few dissatisfied "customers" can take solace in the fact that they can just go and make their Osu-pad themselves.
This video is so amazing, it's not just about some wacky keypad for a game that I don't play, but also it's a drama video about some product that idk why it should exist, but hey, looking at all those PCBs and electronics reminds me of that good old times when I used to study that and then dropped it because I suck. Anyways, good video.
As someone specialised in this type of thing I'm impressed. Also shows that everyone with interest and a bit of determination can learn the basics of this stuff and can get something working. Also very helpful when there is a community around that is open to helping others without too much judgement. I think that's one of the biggest reasons why so many people aren't even willing to try they fear being laughed at.
This is still amazing 12:37 I've read this document for less than 30 seconds and I wouldn't trust this guy to screw in a lightbulb let alone make a pcb
i have never heard of any of this controversy. i didnt know keypads specifically for this game existed. i forgot this game existed. yet this video showed up in my recommended. and i loved every damn second of it
small point, at 11:20, the box in your house's wiring uses breakers, not fuses. breakers simply break the circuit when they trip, whereas fuses are one-use only and burn through when they trip. probably not the best option for overcurrent protection because you'd have to open up the board and replace the fuse every time the current rating is exceeded
yeah, they're not the same, but I used the analogy because it's closest in function to something a layman could understand. Although for the PCBs I believe keyboards use polyfuses and not regular fuses so replacement is not necessary :)
Oh snizzap, I never knew about the original project but this looks groovy! I know at least one comment already mentioned IIDX, but it would be interesting to see this applied to a custom DDR/StepMania/ITG input device as well!
stumbled across your channel, had no idea there were tiny keyboards for rhythm games! have 0 electrical or engineering knowledge but the way you explained everything was very concise and straightforward, from the DIY guide to the Lotus shortcomings. I almost believed I could make a 3k myself at home kekekeke subscribed!
I didn't know you were so knowledgeable in Computer parts and Electronics, I will definitely be waiting for more videos like these as I'm currently studying in this field. Thanks for the great video!
also if traces are cut off you use the board as a prototype, look into how your traces are layed out and then solder a jumper wire between the start and end of the bad trace. You could post a picture of that working and tell your customers the next batch is on the way. Also ALWAYS PROTOTYPE.
"Today I woke up and chose violence" Okay, because of those 5 seconds there at the beginning of the video, im subbing! I dont care who you are, those 5 seconds catch my attention, so its worthy.
I'm just leaving a comment because I have no idea how I got here. I have never heard of OSU in my life or lotus or 3k keypad, but YT algorithm amr? I was highly entertained by your content and I am now fully invested in this hahahaha. Awesome stuff and good on you for going forward and learning new stuff this way. Brava.
have to say, your keypad looks better. but seriously how can lotus fuck about like this? i make my own 3d printed boards and handwire my keys for fun, its not hard, how can they justify spending months on a simple 3 key board, I just finished handwiring a 24 key gaming pad, took me about a month to design and print, and most of that was designing the ergo for it
It's because they had no desire to make a working product in the first place. It's just another get rich quick crowd fund scam. Also big ups for hand wiring!
Got into this vidoe by algorithm, but let me say two things: 1.) Your custom build is freaking amazing and I don't play Otsu! But i would love to try to the other music type rhythm games And 2.) that line on the first intro, your motto fucking amazing! And i never heard this company Lotus but I'm glad that I'm not gonna buy their products if they keep treating their customers a shitty way. Good video and keep up the good work.
I dont know sht about this stuff but it was very interesting. Also it's pretty cool how you just try things out and get them to work. I bet you inspire many people with these videos 😁
been in tech / working in tech for 20 years considering everything on the PCB to be pure magic. Thanks for blowing my mind on the accessibility of PCB design software & learning materials. Can't tell what I'm gonna make, but definitely looking forward to messing it up -- 5 parts minimum means 4 to blow up for free!
This is astounding. Entirely outside of what I would have ever imagined possible. You literally just went "yeah I think I'm gonna learn how to make my own PCB from scratch" and did it in *days?* You're a genius.
For what its worth, something that I learned while still studying for my bachelors in engineering is that Engineers are nutjobs by default. We're just being taught how to channel that into engineering work.
Thank you for not only taking us through an awesome project, but also demonstrating just how big a scam lotuspro's business model/practices are. The world needs more content creators like you.
love this video. I think that Chris is definitely going to kill lotuspro with all the delays. Wonder what the next totally real company he starts will be... 🤔
This was a really cool video to watch, I just finished my first year as a computer engineer and I have no idea about PCB design but makes me wanna try and make my own keypad now, great vid!
I don't know what any of these things are besides picking up that it's a controller for a game - but someone liked me this and said "do you want to see a murder" so I was here till the end. Awesome job, it makes a project like that seem way more approachable.
I don't play Osu!, I've never heard of this Chris guy or the companies he's been a part of, but as an Electronic Engineering Technologist that has made circuits of my own in the past, that guy should never claim to be an engineer. I doubt he even knows what the components do, let alone how they work. You did an amazing job for this being your first project (even if you did use a ruler app to measure your distances, lol). This Chris guy should never be given money by anyone ever, but I feel like you could totally sell your product (after fixing the LED issue, of course).
As an IEEE researcher, I can say it very well that Chris is not an engineer at all, and he would need like, at the very least 15 years to get 5 engineering degrees.
Oh boy an IEEE researcher in the wild! Quick question, do you have to still pay membership (and society) dues + access to the articles if you're a researcher? It's something I've always wondered, but never found out. Since apparently the IEEE charge a hefty price to get published with them already, so I wonder just how much you get back for it.
I always get irritated when youtubers have the gal to act high and mighty in their videos when they don’t even take the time to add subtitles. So thank you for being one of the youtubers considerate enough to put them in.
up until now i had no intrest in tiny keypads, and no knowledge about lotus, about you and about osu. but huge kudos to you, i love when people shove it up to scammers who claim to be more than they really are. love your spite, you magnificent petty bi-
a camp what i recently went to taught s how to solder by making a soil water tester thing and i got way to intrested and now i am watching these videos with 0 idea what it means and i love it
You're so funny. I've never played OSU but I loved this project! Also as someone studying Electrical Engineering as long as it works in the end I'm not mad at the small rushed details. Subscribed 😀
i watched this video a year ago with no knowledge of keyboards and now a year later i have come back with a custom keyboard that i am typing on rn and a ton more knowledge of keyboards and i am still amazed by how much you learned so quickly.
I legitimately love this video. I'm not that into osu! if I'm being honest, but I'm saving this video for later for sure, because part of me wants to mess around later and see about making my own stream deck sort of thing using something like this. And seeing the whole thing about there being a minimum order of 5 just made me think that if I can ever get around to this, and have the cash to burn, I could make extras and either just have backups, or the more likely option, make custom ones for each of my friends.
aaaa i'm so tempted to try building my own 4 key keypad for osu!! (since i play taiko) and this video just tempts me even further. you're so awesome for doing this!!!
This is so cool, I was actually considering doing something similar but a bit different, and I don't really know if what I want is really possible but I was going to start looking into it and seeing what I can come up with. I also love the way you handled this situation and addressing everything, it's a pretty reasonable way to deal with it! Hope you make some new videos soon, not many channels I enjoy watching that play rhythm games
I think the fact that Tokaku made this keypad with no prior engineering experience while Chris made five prototypes that failed due to simple mistakes shows that Chris's incompetence is on a level that I never thought was humanly possible.
