Can I do it?

1 Upvotes
essentially the end goal—that is, from 6-pin to 8-pin
Soldering done on all 6 wires; 2 of them I had already jumpered (on male 8pin), as can be seen in the second photo.
essentially the homemade 6pin female to 8pin pcie adapter

I’ll try to be as direct as possible in explaining the situation. I needed to convert a 6-pin PCIe connector to an 8-pin PCIe connector. I already had all the components, but they were in two separate parts: an 8-pin female connector (of which I’m using only 6 pins, leaving two side pins disconnected) and an 8-pin male connector, which uses two ground (GND) pins derived from the incoming ground lines. Essentially, the cable needs to handle 150W without melting. Based on my online research, it’s theoretically possible, but in practice, the connection I’ve designed would likely result in high resistance and overheating—due to Joule’s law. So, I’m asking those who *actually* know—not just those who are guessing (I can guess just as well as anyone else)—is this feasible? Or is it better to just buy an adapter that uses continuous cables, without any soldered bridges in the middle?

HDMI input to USB-C DP Alt Mode output with PD and USB-A power?

2 Upvotes

I’m trying to find a compact way to connect my j5create ScreenCast 4K to a USB-C display without a bunch of adapters.

Ideally I need HDMI input, USB-C DP Alt Mode output, and USB-C PD input to power the display. A powered USB-A port for the j5create would be a bonus, but isn’t essential

I found this Veeloon HDMI-to-USB-C adapter, which looks close, but doesn’t have USB-A output.
Does anyone know of an all-in-one solution, or something better?

My previous post about HDMI-to-USB-C video and power (I no longer have the docking station I did when I made that post)

J5 Create HDMI (male/input) -> [dongle I want] -> USB-C Alt DP output (audio/video)

USB-A power for the J5 create dongle or PD passthrough to power the device receiving the signal (like a portable monitor) would be bonus features but not essential.

Why are these so hard to find? There are a million USB-C to HDMI converters.

Would you trust the cheap connector, or pay extra for the better locking mechanism?

Help identifying this 3-pin connector / power cable

I have a Feit Electric LED floodlight (model FD30RGB/BA1) that I'm trying to find a replacement charger/power cable for.

It has a round, 3-pin male connector (pictured). Does anyone know what type of connector this is, or where I can find a compatible replacement power adapter?

Any help identifying the connector or finding the correct cable would be greatly appreciated.

Photos borrowed from eBay which incorrectly identifies it as a Sony Handycam VMC-15FS. Came in a bag full of other random camera cables but can't figure out what this is. Has RCA, S Video, and an 8 pin (or less) rectangular-ish connector.

Sorry if this is the wrong sub. Everyone at work either doesn’t know, or tells me to ask chat gpt and I’d rather ask real people haha. I plug a cord into this box and into my computer to project my computer to the wall. My computer fell a week or so ago and the cord broke, and I threw it away not realizing how much trouble I’d have finding a new cord. See photo. TIA!

Dieses Teil Schirme ab , dass heißt dass mit dem Teil im Kern ist ein Metallisches -Magnetische ummantlung so dass keine anderen elektromagnetische Strahlung mit den Stromführenden Kabel Zusätze Daten eingespeist werden. Im Prinzip durch die Schirmung kostsnnte Leistung.

Howdy all!

I bought this a while ago, somehow from the move I lost the cable, I recall it having one of those soft black toggles for On/Off on the cable that plugged in. There's no identifying factors on the back of the sign for amps, volts, watts, etc.

The inside hole is 5.9mm from what I could tell, and the knob the best I could measure it with my calipers is around ~1.9mm. * also it looks to be about 9.8mm deep.

I haven't had luck searching online for it, any and all tips for a cable would be super!

Any ideas on what cable this is. It's black with a 3.5mm jack and single ring. All the obvious searches come back with arials which I'm not sure would work. It's from an X-Sense weather station and used for an external temperature station. Both say 433Mhz if that helps
