Holy shit, the PCB design of this new sensor board, called Ophanim, of CERN’s Aegis experiment just fucking slaps. Right now, there don’t seem to be many images of it on the web, but I hope to see more in the future.
We support over 80 student teams, Ecurie Aix one of them. We were invited to their partner day, last Friday, to have a look at the progress of their formula student racing car. It is great to see their work. Our PCBs together with parts from our partner Würth Elektronik allow the team to quickly iterate their design and build a better, more efficient racing car. #student #team #pcb #aisler #electronics
About that BusBoard Prototype Systems SB4 board -- they're expensive. They're more than $6 each (Canadian) plus shipping from DigiKey. They're $10 each plus shipping from Mouser.
That's a lot for a hobbyist when you're experimenting, especially if you're making mistakes.
I looked around again recently, and couldn't find anything I liked at a reasonable price point.
So what does one do in this situation? Well, if you go Overkill 9000, you design your own prototyping perfboard and have a bunch manufactured for you! When you design your own, you can give it any features you like. So this one has:
18 x 36 (648 holes total)
It's two 18 x 18 sections, though I didn't have them scored for snapping.
A total of 6 horizontal busses in groups of 2, at the top and bottom plus one in the middle.
3 sets of 2 vertical busses within that space between horizontal bus sets, similarly edge - center - edge.
Then each row has a 6-hole pad on each side of the center 2 busses, which are spaced for IC or other standard 0.4" component layout.
Made of proper FR4 fiberglass. Good copper, good soldermask.
Silkscreened row and column IDs on both the front and back, at both the start and end of each row/column (and they match up with the back...).
And silkscreened boxes on the front showing the pad/buss pattern - no more flipping!
They arrived today and ... they're beautiful.

First Look at the Bare Liberux Nexx PCBs
Our redesigned prototypes have arrived completely bare! These are the raw PCBs, fresh from manufacturing, before any components are assembled.
It’s been a long wait, but they’re finally in the hands of our assembler! Now, we’re excited for the next step: having them fully assembled in our hands. 
Stay tuned for more updates as we bring Liberux Nexx to life! 
One of the final modules for my #StackSynth project: the #noise generator. It outputs white, blue, and pink noise and uses a #3904 and a #TL074 with a lot of resistors and a couple of capacitors.
It is based on Moritz Klein's video: https://youtu.be/0yB_h_wFkh4
I prototyped it on solderless #breadboard and then designed the #PCB in @kicad and let @aislerhq manufacture them again. It turned out quite nice and sounds great.

Not every project runs on the same schedule.
Some need to ship by the end of the week. Others don’t.
That’s why we let you choose:
Blitz for faster turnaround when speed matters
Budget for standard lead times at lower cost
Your board. Your timeline
What’s your default: speed or cost?
Almost finished! I just need to glue the sections together and I think I can call the hardware side of this project done and dusted!
Those PCBs were manufactured by PCBWay (who kindly offered to sponsor this project), and I definitely have nothing to complain about: the ordering process was as easy as it gets (upload Gerber files, select features and place order), build time was 3-4 days as expected and the quality and finish are excellent! 
Overall everything went absolutely smoothly, so I'd suggest you checkout their website next time you'll need built-to-order PCBs: https://www.pcbway.com/
I got the "Amp Switcher" PCBs in the mail a few days ago 
As I plan on building both a 6-way and a 2-way switcher, I ordered boards (5 of each) for the larger size only. The "relays array" board is 2oz copper and has a slightly different color.
The photos also show a "control matrix" board resized to 2-way switching (bottom right); this is easily done by hand using brute force, although I suggest using pliers to ensure it's all cleanly cut.
Well look at that, splitting everything into individual PCBs paid out. Not only they're simpler to make but it's also cheaper.
My last attempt at panelising everything into one PCB costed me about $80 including assembly. This time around three separate PCBs cost me about $35. That's two keyboards worth of parts, btw if that's not clear
And when i mess things up, I can re-fab only broken PCBs
Someone essentially designed a #PCB that they're now selling bare or with NAND/SSD pre-soldered for upgrading/replacing the #SSD module of your #Apple #MacMini M4 very easily. It's amazing how informative and transparent the video is at meticulously explaining the engineering design and component decisions behind their custom module, when I expected them to only demonstrate it, nothing more.
Unrelated note, the moment the dude tried to show an example of what an airplane "rudder" is by showing a picture of MAS's, in combination with his distinct Malay, (Americanised for YouTube) English accent - I immediately checked his website and Linktree and right enough, the dude's a Malaysian lol.
Good to know that if I decide to get a Mac Mini I could upgrade the SSD myself without paying Apple or expensive shipping cost. I'd still probably need to upgrade from the measly 16GB of RAM though on the base model by paying Apple's 10x markup for no good reason.

The tooters have spoken! 74% of you favor JLC. Thank you for participating.
And I just ordered my board from OSH Park.

Electronics tooters, do you prefer JLCPCB or PCBWay?
@itskanishkp define "from scratch"?
Using a small micro controller board (promicro or RP2040 zero) and designing you own PCB with kicad is achievable and their are guides on how to do it as your first #PCB project. But doing a hand wired build is simpler for those that find manipulating hardware easier than software.
A simple sandwhich case and getting the plates cnc'd or laser cut is cheap.
Definitely buy switches and keycaps.
