@cursedconnector want to make this thingy for a long time even when I already have digital oscilloscope MHO98 it doesn't allow export of digital signal's I will just need to finally order those boards thanks for reminding me :)

So here's the thing. Saleae make solid damn HW, but they also know they are selling to mainly corporate (ie, these things are mega pricey nowadays). If one is in dire need of an affordable alternative, pick up a Pi Pico! 100Msps for single-digit dollars.

@kernelstub @saleae what work? only tool needed for that is a saw...

Hi @saleae , Could you guys lend me one of these bad boys so I can do my work with the flock cams and when I am done I will just send it back </3

@SipeedIO @kernelstub @saleae I wanted to buy it from ali but eu just added the stupid per package tax... :/ also idk about the price the raspberry 100m digital analizer costs under $30 while this one costs like $98

@kernelstub @saleae It is on aliexpress too! Also you can check the wiki first: wiki.sipeed.com/slogic16u3 And we will release 10Gbps SLogic32U3 in 2 months !

damn, interesting... 7 people have the same exact room, laptop, setup identical to pixel... blue tick users would NEVER steal content for engagement, NEVER! I swear to god... this is the 99% of the twitter now... il have make an add-on to block every blue tick users on fy page

@DevWillTech maybe also some specs? i mean, how many passes, what power, speed?

using a defocus UV laser it was possible to get selective UV hardening of the solder mask might be slower than a UV lamp but allows for less steps the scratching is my doing, it will require a post cure cook too fully harden it

@fuzziphy looking for how much those machines cost... well, I am more than happy from my setup... might get back to milling, but I would first need to make a tool changer for my 3018...

@Halina20011 I would say it’s faster than etching with the setups and less hands on, since my machine has a 6 tool auto tool changer

CNC machined PCB edge connector was a success

@fuzziphy for how much did u buy them? I found that it was before like 60$ but now I can't seem to find anything cheaper then 135$ + 50$ shipping :/

My pair of AsRock AMD BC-250 boards just showed up from eBay. These things are stripped down/binned PS5 APUs that run Linux. 16GB of unified 448GB/sec GDDR6 per board, 6 Zen 2 cores, 24 RDNA 2 CUs, apparently unlockable to 40 CUs in the silicon lottery. I plan on making a power distribution board using the two B2B Molex power connectors they have on them, and mill some kind of enclosure on the Shapeoko. I’m curious about using DisplayPort to stream 4x 8Gbps lanes that GPU shaders could pack into texture buffers and a quad to the Ultrascale+ FPGA

@turingpi now tell us the price...

Datacenter mentality. Desk-sized hardware.

@Redstone_Bi cool! yeah, 3... I mean, it's a really good price 😅 but i will still need to deal with the programmer cuz the one which I bought didn't arrive and it got cancelled :/

@Halina20011 3?? My original plan was use those ports as data bus to make a multi chip system, but ends up practicing some basic circuits on it🙂‍↕️

今把新zynq换旧zynq

@notagoodiea @Redstone_Bi that board is a controller for crypto mining now that they are old, so you can find it cheap second-hand for like less then 20$ which for that fpga is sooo good

@Redstone_Bi 好奇原本是做甚麼用途的

@fuzziphy I mean, mainly on ur story, I found already that thing online but I am interested in ur story, the connection which u have been doing (the nvme to pcie whichu made) and for what u will use it and how it will perform

@Halina20011 There's a lot of info on these boards already. I could share my manual Debian stable + backport setup though, which wasn't covered anywhere elektricm.github.io/amd-bc250-docs/

Got Debian stable + kernel 7.0.10 backport, and llama.cpp installed on this BC-250. It's successfully loaded a model (Vulkan backend, as ROCm afaik doesn't work on this APU)

@i2cjak haha, looks il finally need to get a the rpi i wanted to buy for a long time

Accepting submissions until July 1st.

I AM PROUD TO ANNOUNCE ROUND 2 OF THE OFFICIAL AMERICAN EMBEDDED PI PICO FASTEST SOLDERING COMPETITION ($200 PRIZE POOL) Rules: - MUST PLAY SKRILLEX SCARY MONSTERS AND NICE SPRITES WHILE SOLDERING (loud) - MUST USE A REGULATION PI PICO (Pi Pico 2 and W variants allowed) /cont

It looks like i don't have to use silkscreen, flux is awesome!

well, I f up... for some reason, the pcb was mirrored around x axis... :/

very happy how it turned out...

@fuzziphy first seeing this type of vias, what are those? I know those that need to be punched, but these look like a nail?

Onto the worst part of milled PCBs. Dropping in 0.4mm via pins.

@LiuYu7809 @fuzziphy that u do with so many of them 😅

@fuzziphy this？

This thing showed up from eBay.. A decommissioned FPGA from alibaba. They have a Xilinx Ultrascale+ XCKU3P in them that the chip alone sells for $3k on DigiKey. 356k logic cells, 26Mbit block ram, 16x32.75Gbps transceivers, and 1368 DSPs. They have an x8 PCIe connector, two SFP+ cages, and a clearly marked JTAG header. And as @lauriewired pointed out, they are supported by the free version of Vivado
