Krasnogorsk-3 Super 16 mm viewfinder mask modification (1.33:1 to 1.66:1)
Okay, let's modify the viewfinder for a complete super 16 mm conversion (after the gate and the recentering ring). For this project I used a thin copper plate and a CNC laser cutter to make the new mask (thanks to the jeweler).
MASK MEASURES
Diameter: 18.5 mm
16 mm (original mask): 9.6 mm x 7.2 mm (1.33:1)
Super 16 mm (new mask): 12 mm x 7.2 mm (1.66:1)

Controlling the position of a continuous servo with a potentiometer and arduino
Просмотров 27 тыс.3 года назад
This is a quick attempt to control the positioning of a continuous rotation servo with just a potentiometer. With the first code I check the exact middle point (where the servo stops, 1500 theoretically); in the second one I take control of the servo. DISCLAIMER: Because of the big inaccuracy of these motors, you can't express rotation in degrees and there is no angle feedback; so the positioni...

Fryderyk Chopin (Vinyl, 1965) - Side 1 - LIVE RECORDING
Просмотров 2714 года назад
A proposito di questo capolavoro della letteratura pianistica, leggiamo le ispirate parole di Franz Liszt, che alle Polacche ha dedicato il più bel capitolo del suo libro su Chopin. Bisogna collocare fra le sue concezioni più forti la Grande Polacca in fa diesis minore. Il motivo principale è di tono sinistro, come l’ora che precede l’uragano; l’orecchio crede cogliervi interiezioni esasperate,...

SamplerBox demonstration (full standalone piano with Raspberry Pi + Studiologic SL990)
Просмотров 28 тыс.5 лет назад
Quick demonstration of Samplerbox a project by @yellownoiseaudio6073 hacking my master keyboard Studiologic SL990 (I use the same input power but stabilized at 5V on this configuration). The project SamplerBox has been started by Joseph Basquin. Official website: www.samplerbox.org #raspberrypi #samplerbox #diyprojects
my piano has 10 key poliphony, i would say 14 is beyond great and considering its so small
I am planning to do something similar to my mid 2011 21.5 inch imac. can you recommend an lcd driver board? I cannot work out which one has support for audio via the imac native speakers
Really neat design! Have you encountered servo motor jittering problem? If yes, how did you solve it?
wait a second... you're a phony! A great big phony!
can you share schematic from this ?
Hi. Do you sell them?
For those wondering if it his possible to connect the power PCB to the main LCD commander board for the 2011 27'' Imac, it is not possible. A red light from the controller PCB is going to be there but the screen won't respond indicating that it is either missing power or getting too much power.
Can you make a video about repairing the light meter?
Hi, So there's no need for shorting pins on the PSU to power on like on ATX one ? Also, do you have an idea how to utilize the original backlight inverter board ? I tried to plug it with original PSU cable instead of the AliExpress inverter and nothing happened. I heard that you'll get noticeably lower brightness worh AliExpress one.
I have the 27" version.
Wowwww...👏👏👏👏
no git links? not open source?
Sure it is, check in the description.
What size of plastic standoff did you use? I want to order some from amazon but they come in 3 sizes.
I used two standoffs, one set is 1cm and the other is 1.5cm. They’re just for support, so I didn’t drill into anything.
Cool video, I'd love to see more videos about K3 mods. There's almost no good content on modding these cameras. But the position of the ground glass after a super 16 gate upgrade is then off to one edge. So, while the new mask's shape is 1.66:1, the image in the viewfinder is still not the accurate frame, correct? That is, wouldn't you then need to modify the ground glass' position and shape as well?
Hello, I think is not necessary to modify the ground glass' position. I see that apart from being positioned before the gate and not after, it is also wide enough to cover the projected image. So using an off-center ring should be enough. Correct?
@@sandrolab The off-center lens ring does re-align the lens' optical center with the new super16 frame center, which is important for many reasons, but after changing to a super16 gate (recentered lens or not) you're ground glass will now be offset. The re-centered mount doesn't do anything to compensate for the viewfinder, just the film frame. While writing this comment, I put up this Short to demonstrate what I mean. This is my K3 after a super 16 gate and re-centered mount was added, and the viewfinder mask removed entirely. Observe the difference in the shape and position of the viewfinder view (white) versus the actual frame (orange). ruclips.net/user/shorts9UgZqH4Qi_E
I was gearing up to test some film shoots, but you came from the future! Have you already tried changing/modify the ground glass position or found other solutions? Thank you so much for this priceless information.
@@thousandoaksmall1995did you try to remount the ground glass? Are you just going to compensate each time? Have you filmed since you modded your camera? Thanks!
@@footballfrequency7979 I didn’t move my ground glass position and don’t have the guts to try. The popular k3 modder Max Karpenko has though, I believe. I myself just made a diagram of how to compensate for what will be the real frame lines.
Thank you for showing where the K-3 mask lives and how to access and modify it! In the middle of performing Ultra 16 mods on two cameras now to 11.66 mm × 6.15 mm = 1.85 aspect ratio. Is the mask a 1:1 with the actual film gate size?
You're welcome! Actually I did a simple proportional calculation based on the size of the mask and not the gate. So I kept the same height, given that we can consider the viewfinder as a secondary and independent optical system.
hey, thanks a lot for your video! I am about to do the same with my 2011 27" iMac and was wondering where exactly is the 12V DC (from PSU) Plug coming from (0:17). would help me a lot!
You're welcome! As you said, that plug/wire comes directly from the PSU to which it is soldered (0:11). Keep in mind that for a 27-inch, the pinouts could be different.
nice
Wow, great ... (and beautiful playing). How does it compare, as the player, to the SamplerBox (Raspberry Pi)? Is it the case that for beginner/intermediate players who don't use all that polyphony, they're indistinguishable?
Wow 🎉🎉🎉
This is brilliant. You could have me fooled at some passages. Good job!
Sounds superb to my ears. How big is the library?
The micro SD's content is around 330MB.
hey man, just wondering if you could upload an updated link for the code? i was feeling pretty hopeless about this project im doing until i saw this :C
github.com/sandrolab/continuous-servo-pot-control
Sorry but what is the function? Charge differents WAV sounds or something? Nice work btw🎉
Thanks! Actually, there is no a real function. I made this just for playing a dynamic piano (or any samples you want) with my mute keyboard, without any computer or other expensive external sound module.
Amazing! This is excellent and what I'm looking for.
Hi, this is so amazing! And i want to build one, can i use any wav trigger with sd card slot? Or will this only work with the one you are using? Tnx in advance
Hi, thanks! Yes, there is only one version of WAV Trigger and you can use it without any problem with Arduino boards
I really need the code for position control.... And the drive link is not working 😢.... Please help @sandro

Thanks
Congratulations on the project and the music performed. Which midi controller are you using?
Studiologic SL990 Pro
Sandro! please can you help with a full video how to connect the original speakers to this board? I think you have a bunch of messages asking a full video! Thanks!!!
You're right, I probably should make a video about it! Anyway it's quite simple for the audio connections: there is a 4-pin connector on the board (two for every speakers so ground and signal) and every speaker has 4 wires, all you have to do is to join together grounds and signals
Hi Sandro! Thank you very much for your answer! It wouldn't be a problem to try but as the colours are not only red and black for example that's where I have doubts when connecting and I wouldn't want to damage anything. On the other hand in the video you can't read very well the small letters of the connector that is on the board. Thanks!!!!@@sandrolab
@@sandrolab I think the screen of that iMac uses a 40-Pin 4-lane embedded DisplayPort connector (eDP), you can just solder a DisplayPort/Mini DisplayPort on a 40-pin Embedded DisplayPort cable, add a DisplayPort to HDMI and/or DisplayPort to VGA adapter to use it for almost any PC edit: you can add an auxiliary audio input from DisplayPort/Mini DisplayPort, HDMI, and the 3.5mm Auxiliary input, and an audio amplifier for the speakers everyone else: you **n e r d**
Would love a Long vid!
update Drive link please, it is not working
👀
extraordinario, muchas gracias, estoy haciendo lo mismo con mi viejo imac
muchas graciass SUIUIIIII
Hello, I watched with great interest your video about converting an iMac into a monitor. Indeed, I have the same project to convert iMac 2010 21.5 inches with the same type of controller card. Could you give me more details on the principle of wiring and the realisation (welds, connecters, insulation, fixing the elements...) Thank you in advance for your answer. Best regards
Wow! I need this!
Tienes el modelo del controlador??
Is there a quieter servo?
Cool. Impressive how you can play while disassembling the hardware with both hands!!
This is awesome❤
Wow what a completely useless video, thanks for giving me absolutly zero information
Hi there! This is inspiring! Congratulations! One question, is it possible to use the USB port for USB MIDI In? My digital piano has only USB Midi out. However as I see both would be B ports (in my piano and the arduino), not A to B cable.
Thanks very much! I think it is possible to use USB protocol instead the classic MIDI, but for sure you have to code something different...
that's great! we're can I buy this?
Amazing !
What is 65000 in the code , can u explain why 65000 is used for, this would of great help.
When you did that run downwards I figured it could only be one song, glad I was right haha, it's a banger What's even more of a banger is getting such a sound out of that hardware, I think I need this :)
How???❤❤❤ For sampling sf2
Any chance you can do a full video on this conversion? Thanks 🙏
Great video. I hope you can give full video about it. And with some link to buy the product. Thanks a lot
Do you still have 3D model for servomotor? Can you share? Please
This looks and sounds awesome! Would this be possible with ESP32 Audiokit too? It’s microcontroller + sd card reader + audio codec bundled in one, and seems way cheaper 🤔
I didn’t know it, but I would say it’s probably better than the wav trigger not only for the price but also in terms of polyphony. I will definitely take a look. Thanks so much!
Great video! Did u notice any difference in the display brightness when compared to the original setup?
thank you I'm going to try this - is there a name for the type of socket the speaker cord on the board uses? how do I find that?
Did you figure it out? also looking for it
@@MarcelKress-zd3yj nope. I did the HDMI conversion though and the video is great - just not sure if the board even powers the speakers at more than just a line level
@@livingganja alright - I think ill try it out by soldering to the pins, and if it doesn’t work i might add a small amp
Yeah
