I’d go with the DS3231, given it has a built in XTAL (desirable feature), and is likely old enough, given the datasheet was on rev 6 in 2008…

Congratulations. You’ve decided to embark on the exciting adventure of building a gaming computer, and you’re in for a challenging but fun time.

Thanks for the link, I’d never heard/seen the concert. (Not surprising, I’d lost all interest in EJ by that time)

I think this is ingenious .. it’s a simple “co-bot” that can significantly speed up assembly with very low investment.

The tape feeders come in a variety of widths, to suit different size tapes. You’ve probably seen if you’ve ever ordered SMD components in quantity from Mouser, Digikey, et al. SMD components typically ship on large tape reels, which are machine fed into automated pick and place machines. However, if you’re doing it yourself in smaller quantities, having these manual tape feeders on your desk can be a huge help. Rather than having scraps of tapes scattered across the working surface, you can instead have them neatly managed at the edge of your bench, providing components as required.

Would you believe that you can take a cheap 3D printer and easily convert it into a full function pick and place machine to help assemble your PCBs? No? Well good, because you can’t. A real pick and place needs all kinds of sensors and logic to identify parts, rotate them, make sure everything is aligned, etc, etc. There’s no way you could just bolt all that onto a cheap 3D printer, and let’s not even talk about the lack of closed loop control.

DARPA is working on several pieces of the puzzle to realize its goals, including formulating standards for chiplets to enable a plug-and-play model for the industry, devise faster SerDes technologies, and develop low-cost interposers/bridges for die-to-die interconnects. The agency also is looking to develop new pick-and-place systems, enabling chiplets to be placed on the package at high speeds.

To help the industry get ahead of the curve, Semiconductor Engineering has taken a look at the various chiplet approaches.

This runs into my personal opinions on how the patent system can be improved – I think patents need to have variable terms depending on market. If this article came out a decade ago on Hackaday, when APA first just came out with their product, and WS2812 was the clone, perhaps there would have been a little more sympathy for APA, because an RGB LED with controller in one package was a pretty new idea. (Or perhaps not, because WS2812 was probably cheaper, and had a nicer interface). But at this point, the WS2812 has sort of turned into a hobby standard and kind of the brand name, so it’s hard to like APA over WS. Neglecting whatever issues may have delayed enforcement actions on APA’s part for a good decade, I feel a patent like this, which would not have needed more than a few years perhaps to recoup development costs and lose its novelty, should have expired by now.

I kind of wonder what the appeal of a home pick and place machine is. The amount of time spent getting this system ready to press ‘go’ would have had the PCB populated by hand. This system wouldn’t lend itself to processing more than a couple of board without having to redo all of the bits of tape (counting how many of each component, cutting it accordingly, peeling off the film etc.), so is the time really well spent? The only benefit I can think of is if somebody regularly makes one-off large PCBs with heaps of components, and even then, the machine configuration and maintenance seems like it would erode any benefit.

If these are for a pnp, where does all the empty reel/ tape go? Even hand picking, the empty tape would start to get in the way.

ASUS covered the rear panel assembly with a black plastic overlay to give those components some added protection. The TUF Z390 Pro Gaming motherboard contains the following integrated ports in its rear panel assembly: four USB 3.0 ports (blue), two USB 3.1 Type A 10Gbps ports (teal), an Intel I219-V GigE RJ-45 port, an S/PDIF digital audio output port, and five analogue audio output ports.
