Eurorack DIY: 909 Rimshot (Episode 7) - Build and Demo
Вставка

- In this series I will recreate the TR-909 Rimshot voice as a Eurorack module.
In this episode we will assemble the PCB and put the module together. There is also a demo of the module.
You can find all of my designs on my GitHub:
github.com/tki...
Some modules that I have designed myself are available in my Tindie shop:

Thank you for watching!

Thank you. You are doing real good work explaining all the details!
Thanks a lot!
Your videos are great and very helpful! Thank you
Thanks a lot, I happy to hear that you like them.
hey Tommy!! love your series on the 909!! I finished my RE909 I need to make a video on the build process but it's nothing compared to the work and effort you have put in here!!
Hey Gareth, thanks a lot!
I'm very interested to have a peek at the RE909 build - I doubt that I have the time and money to build one myself, thought... lol.
WOW! This was somehow the best part! 😱🤯 I have been putting off surface mount for years lol, but I realize I'm just being obstinate at this point lol
Thanks a lot! I admit that there is a barrier with SMT, but for me it's the only way to go. TH IC's are getting harder and harder to get hold of.
Sounding great as always!
Thanks a lot!
Okay this video suprised me... I never expected to watch a YT video without skipping any part...
1. Stereo microscope is way better than digital one (recently swapped my digital for a trinocular). Makes it easier to read IC numbers and soldering is more predictible (with stereo you can also "see" the distance instead of flat 2D image).
2. Soldering order in SMT matters. I learned that the hard way where I needed to approach a 0402 capacitor from 10 degree from normal (axis) angle. That's when I switched to going with paste (still have mine 500g Sn42Bi58 bought for 20$ on AliExpress). It's faster, cheaper and can be easily automated with PnP machine. Frying pan with sand is great reflow device (especially we've flat-rate gas bills uninfluenced by usage amount...).
3. I use your tips in reverse... That big tip is "wave" tip and this technique is great to solder SMT (especially 100+ pins). You only need to add a little bit of flux to pads, because otherwise it bridges quite easily. Quick drag and entire side of component is soldered (eg. 120 pins of SODIMM socket with 0.5mm pitch or 25 pins of IC with 0.4mm pitch). To be precise with my tip usage: JBC C245 001 for soldering THT and JBC C245 045 for soldering SMT. If I solder large amount of THT pins in a row I go with JBC C245 039 and drag soldering (I place appropriate soldering wire parallel to pads and drag my soldering iron along the wire - from end to spool).
4. Breadboarding is a bad idea. That one I also learned the hard way... Those things are so unreliable that I can stand them only when soldering pre-made module (those breadboards are great at holding headers in place). I just get a PCB from JLC and build device. If it doesn't work debugging it, if it still does not work I recycle valuable components and throw the board into "just in case you will need to desolder something from me again" bin.
5. For anyone looking for soldering iron. Don't skimp on budget. It will make your work way more pleasant. Chinese branded stuff has impressive quality (eg. Sugon). Cheap chinese C245 tips are OK'ish. Works fine, but heater dies a bit earlier than JBC ones. For one-off jobs I prefer clones, for "abused" tips I go with original JBC.
You start me thinking I should make UA-cam channel, but my pronunciation is so terrible I can't stand my own voice while speaking English.
I'm learning about EuroRack as my friend asked me if we can cooperate to build some modules for him (imported ones are a bit too expensive).
Q1: What jack model are you using? Tried to find them on LCSC, but failed to get the exact thing (their searchbar is not the best).
Hey, thanks for the comments and tips.
With 100+ pin ICs and 0402 you are definately building more advanced stuff than I do... 😄
Yup, a stereo micropscope is far better than a digital one. I have started to buy parts on Ebay for putting together an Olympus stereo microscope but some parts are hard to get hold of (at a reasoneble price) - but I'm slowly getting there....
Don't hesitate to start putting out UA-cam videos - your accent is part of your personality and background so there is no need to feel ashamed of it ❤
The jacks are Thonkiconns, sold by Thonk in UK. You can get hold of "copies" on Aliexpress if it is easier to buy from China than UK.
@@MeeBilt I'm living in Eastern EU, so it does not matter where I buy (both sources require taxes and delivery from UK is usually 3-5d instead of 7-14, also it's cheaper at shipping). Thanks for the response ;)
Relatively speaking my projects are quite simple. Basic "diagnostic" stuff eg. broken cable detector (cable not wire, it can scan up to 16 wires at same time including being broken and being shorted internally). In most designs I can "easily" fit all routing on 2 SIG/PWR + 2 GND layers (6 layers are still too expensive for most projects) using 13.4 or 11.7 mil traces (50 Ohm single-ended impedance in my stackup).
Mine stereo is a cheap Chinese (branded 'Eakins') stuff and for it's price it is fine. Not Leica, but still pretty good for simple tasks like soldering / optical inspection. Only the LED ring is annoying when you want to change the lens.
Thank you once again! The design of this particular module gave deep insight, and most of it was new for me.
Thanks a lot !
That has been a great series you have made Tommy!
Thanks a lot, Patrik!
Great one, again !
Cool to share soldering session, now I want a kit !
Do you plan to fill your tindie store with 909 modules ?
Hey HarmO
At some point yes, but I will have to make some refinements of my designs before I can do that. For every module I build I realise that I can make improvements....
Count me in then !
Good morning
Do you have the 3d files to print the pro fume extractor or a link
THANKS
Great everything you do I love it
Simon
Hello Simon,
Here's the link:
www.printables.com/model/29401-soldering-fume-extractor-for-120mm-fan
I bought a ASUS ROG STRIX XF120 120mm MagLev with 63 CFM and a cheap carbon filter retrofit set for kitchen ventilation (fume extractor) for my build!
Good luck!
Nice Thanks you Tommy
