It's a small detail, just not sure if you noticed it. Otherwise everything is looking great so far." As opposed to "That incorrectly installed grille ruins the whole appearance of the machine. It's a very basic thing but it really calls your abilities into question." --- End quote --- Yes, :) Inject a little emotional intelligence in there, a bit of encouragement gets coupled with suggestions/advice and people will listen. My work role involves exercising clinical judgment (not medical clinical, there are other forms) and giving advice to clients. Without going into boring detail, this can be exhausting, I need to be very patient with some clients to say the least. Coming here is my stress relief, hopefully to chat about the hobby, compare notes, that kind of thing. Praise is nice, encouragement is better, I mean who understands us outside of the hobby anyway - not many. Collaborative problem solving has been one of the things I've enjoyed most. If someone on the forum makes it feel like work, I get grumpy, impatient even. Guilty as charged. I can take constructive criticism, have many times, sometimes resulting in 180 degree changes of mind in design or artwork, or whatever. At the same time though, I do my research, I'm thorough, I read everything I can, watch YouTube videos and yes, ask for advice when needed. Putting the vinyl onto this cab was a bit traumatic. I didn't have clue how to make sure that I got it right. If I messed it up, I would have wasted $400 AU dollars on artwork! I watched a bunch of videos, finally I found my guy, an expert. I learned what I had to and didn't mess it up thank f***k ;D I'm always willing to learn and be instructed, but hey, you can assume I at least know something about what I'm doing, maybe even quite a lot. If that weren't so, I wouldn't be able able to build a project like this in the first place! --- Quote from: jeremymtc on May 14, 2025, 12:22:40 am ---[ Seriously though, cab looks to be coming along very nicely. I've only got exciter speakers for haptics and a much more basic audio system in mine - will be interested in seeing what you think about your solenoid setup. What sort of voltage are they driven by, and are they controlled by the KL25? How's the latency for feedback? --- End quote --- Getting the sound system right took quite some time. I had these small full range 3" speakers coupled with some cheapy car tweeters. the setup sounded really dull and lacked top end sparkle. I changed out the car tweeters for some nice little Dayton (4 ohm) tweeters and put in my own (simple) crossovers. My original subwoofer amp died during testing and I had to pull everything apart again and put in the current bridged car amp. It's not Hi-Fi but, sounds cleaner and more detailed now especially with the subby dialed up to the right amount.. The 12V solenoids I'm using are rather weak. With the extra brass weight I added to each they click and provide some reasonable vibration into the cabinet. I looked at using DOF to drive these but opted for an extra micro-switch on each flipper button. I adjusted these for sync with the actual button micros so no latency at all. Pics to come! |

I had wondered about the "extra" stuff I was seeing around the flipper micros. I had briefly considered using some small 5V shaker motors wired similarly before I went to the audio-based exciters, so what you've done there completely makes sense. Very cool that you were able to "tune" the solenoid actuation to suit; latency is one of the complaints I'd run across relating to solenoids and was one of the reasons I didn't pursue the shakers. I may have missed it upthread, but have you already figured out the lockdown bar arrangement? |

--- Quote from: Ond on May 13, 2025, 10:24:28 pm ---Anybody else can explain what this means to Xiaou2…anyone? Butt kissing is not called for. If you have ideas learn how to suggest them. Seriously, just basic respect for a fellow long term BYOACer, I might surprise you with my response. --- End quote --- Explaining things to people like this is a waste of time. He won't really 'listen', and will likely troll you excessively on any further details and/or write loooooong essays about tangential stuff nobody asked or cares about. Waste of time. He wants us to be wowed :o by his amazing knowledge about whatever. Look, I was momentarily wowed. his input on the threaded plumb-bob was valuable, I liked that and was impressed. He could have stopped there, but then goes on and on, self-indulgently lecturing about this and that, making you feel patronised (treated like a child), or just plain bored, and it is a massive turn-off. It is all about ego, the 'right' or 'wrong' of it is irrelevant. This fact is highlighted when, after Ond questions the need for all this, he responds with dumb crap about "butt kissing", "Maybe you just take offense to advice, period", then illogically claiming "The problem isnt me." [sic]. Hahahahaha :laugh2: Put simply, it upsets the thread's vibe, and I start just speed-reading over Steve's rambling posts, hoping for the vibe to come back. My suggestion, for him and others, including myself, would be: try to write shorter posts that directly address the topic at hand. Keep your ego out of it and don't ramble. If you've got a lot more tangential stuff to say, consider starting another thread so you can explore in detail, then link to it. Or just mention that you know a lot more about XYZ if anyone wants to go there. If they don't love every part of your ideas, FORGET IT and MOVE ON. They'll take what they need. Finally, if you don't have anything worth saying, then say nothing. Shorter posts are better, and No post is better than a dumb post. With that I'm out :gobama |

Hey Zebidee! Yes, maybe I just could have said "your patronizing tone is a turn-off". Nevertheless, I will be using the suggested improvement to the Tilt-Bob. An adjustable one is better. This build is so busy with more pressing things, I'll get to it eventually. Amen to the short posts. Walls of text are hard to get through even if they are full of useful nuggets. We are a picture oriented forum! Pics or it didn't happen and all that. I love the end of my working week, my last bit of admin is done and I can look forward to blissing out in the workshop for a few days. Things to do: * Add some timer relays to the two amplifiers power lines, I need to address bad hum in the speakers on power up. The hum disappears once the OS boots but its still distracting. I know it's some kind of internal grounding issue in the Motherboards audio design. * Get started on the Lock-down bar. This is going to be a composite of materials including aluminum strip, 3D printed parts and fiberglass. A customized lock-down bar to suit the size of the cabinet is needed. If I could I'd just buy a real one, but there are none I know of that will fit. It's all good. I like the fabrication challenge. * Final coat satin black to the back-box and apply vinyl artwork. I improved the rear venting and air flow and this all needs to be painted the same color. * Fabricate the main play field bezel including some inset LED lighting. Here are some pics of the modified flipper buttons with extra micro-switch fitted to activate solenoids. These tiny micro-switches are virtually silent and very light in action. Even so, I adjusted the spring strengths in each button for a very light action. The 3D printed housing lets me tune the switch on point to match the button. I needed to put these right against me ear, listen for the click in each and adjust until they match. Then I hot glued the switch to retain its position in the housing. No electronics, just mechanical, no lag. Here's a pic of the PSU for Motherboard. It vents out into the back-box. This PSU has an intelligent fan system. The fan only occasionally spins as needed for cooling of the PSU. You can also see the crossovers either side for the two-way speakers system (+ subby). |
