Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Ah - just seen your edit. If you could try the first suggestion of upping the PSU voltage to the DC socket to 9V and if the problem still persists can you double check all the soldering around IC U8. One common issue we've seen is where when inserting the IC sockets into the PCB the odd pin on the s...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

@Ramshackle @willy54584 What would be nice is something like the WS2812B's in a 3mm LED package. That would make the design very simple. @Ramshackle That's great. it's still worth giving the caps another look over if you're still seeing noise issues though. At some point I could do with compiling a ...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Would it have been a good idea to include a phone style socket on board when using a standard phone charger to power the cube? The pin and plug idea is easily pulled out. (I noticed an Image somewhere on here with exactly that arrangement) Or is it a soldering issue with something so small? This wo...

Re: Wemos/Lolin D32 ESP32 development board (HCWEMO0014)

It's my understanding that this is the case with the caveat that a few of the GPIO cells (34-39) are input only and so can only be connected to input pins of a peripheral. For the temperature sensor I've not tried this myself but there is an example sketch here: https://github.com/pcbreflux/espressi...

Re: MAX7219 8 Digit Seven Segment Display Module (HCMODU0082)

They're not actually our product, we're just a re-seller for them. But I see your point about the headers - would make more sense for them to be fitted on the reverse side. I'll feed it back to the manufacturer when the opportunity arises.

The diagram has been updated to show both versions. Your browser is probably still cashing the old image. Try refreshing the page with something like ctrl-r.

Re: 1.3" SH1106 uOLED Display Module (HCMODU0058 & HCMODU0059)

Because these modules are so low power there's probably enough leakage from the internal circuitry on to the supply rails (probably via the ESD protection diodes on the I/O cells) to power the display. It does go without saying that it's not recommended to do this of course.

Re: Pic - K150 ICSP Programmer (HCDVBD0002)

Running microbrn.exe and I can't see 12F635 in the chip select dropdown. can I ask if Is this device supported by the K150? page 1 lists it as supported. Really sorry about this. I can confirm that it's not supported by microbrn and it shouldn't be in the supported device list. I've just gone thoug...
