Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

It looks great. I did wonder why you wanted to make it dimmer but now I see. I've given your YouTube videos a thumbs up and added the link to your project to the first post of this thread.

I can't open the folder to see files though. If I click next I ge...

Re: Wemos Lolin D1 Mini Pro V2 (HCWEMO0018)

Is the pinout the same as on the V1 part? It looks it, but as the pins are differently named it's hard to be sure. Yes the pinout is the same it's just for some reason Wemos have decided to use the actual ESP8266 pin names. If you take a look at the forum thread for the older version there is a tab...

Re: Brass 3D printer nozzle 1.75mm / 0.4mm aperture (HC3DPR0054)

It's difficult to comment on the compatibility of a product we don't currently sell, especially in this case where information on the nozzle dimensions is limited. One thing I did see is that they mention the nozzles which are compatible with their own hot ends are also compatible with Prusa printer...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

Great, thanks for confirming. I'll get this new version added to the first post now. When I clear a screen to display a new bitmap I've been doing a clearbuffer followed by the new bitmap then the refresh HCuOLED3.Cursor(0,10); HCuOLED3.Bitmap(38, 6, D1ST); HCuOLED3.Refresh(); To clear a screen and ...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

I've attached a new version of the library. Hopefully this should fix the issue. Can you give it a try and let me know if it works. BTW, is there any way of dimming the displays (I'm thinking to dim them if no activity after a certain time, not power off just 1/2 brightness or something from a contr...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

Just to be clear you're saying the displays do work after the reset, it's just that you're seeing some weirdness happen whilst the reset? Also, I forgot to mention, for whatever reason they (2 and 3) are briefly backwards (mirror) then the flip forward then clear Yes, both these things are done as p...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

The problem is that the reset function doesn't just toggle the reset pin, it also re-initialises the display. So when you reset all three displays with the reset function, although all three displays are actually getting reset, only the display your executing the reset function for is getting initia...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

I've just noticed that the text in the default patterns library are displaying upside down? Presumably all the patterns are upside down, it's just noticeable with text. Is it possible that you have the layers of your cube connected in the reverse order? Take a look at connectors L1 to L8 which run ...
