It remains only ONE!!!

New eurorack modules from midiphy - preview
Antichambre commented on Hawkeye's gallery image in Members Gallery
it seems you made some progress with the layout :) I'm always interested in those 8 channels sharp 1V/Oct ! You can maybe reuse the front panel and front board from Andy. You will economize some working time, it can help you finish this great module. Best -
LRE 4x1 breakable RGB LED-Ring/Rotary-Encoder PCB bulk order
Antichambre replied to weasel's topic in Bulk Orders
@weasel I received you message. Tell me what you need to know here as everybody can access it too. If I can answer to your question about what I did for the OLRE16 ring mask and window I will do. Best -

No, it's not. If you really want to try it... here a mios32 module for the pixi (max11300). this is a draft ! Please share your work if you do some modification or correction. Thanks -
I added a beat led window with each set. I made some more if people are interested in it. And it remains 2 set finally! Ready ? 3...2...1...Fight!

Don't do that you will remove the painting!!! Plastic is smoother than metal it will fit if you respect a 5mm diameter, thickness of the top should be, 1,2 to flush the surface. I never specified any SMD model, the 5GTH920 hasn't any LED, LEDs have to be ordered separately. No. With some screw.

Not well ;) For the leMec, colors are blue and red with suggested 47 Ohms Have a good build!

Thank you Peter :) -
Yes they are ALPS stem. But all the set are reserved. There was a MOQ, I was obliged to do that bulk to get mine, I've got it now, I already said that's a 'first and last' bulk. Best regards Bruno

Yes I like this "polar" style. And it appears a more finished machine for me but like you said it's a question of taste so there's no debate. It just misses a huge and ostensible "MIDIbox SEQ v4 +" at the back on the white part to assert the whole ;) Best regards Bruno

I took this picture under the sunlight as you can compare their brightness with the others elements(screen, led matrix etc...) -
Hi everybody! The custom keycap were arrived. again, thank you guys for this "+", and the amazing case that comes with!

LRE 4x1 breakable RGB LED-Ring/Rotary-Encoder PCB bulk order
Antichambre replied to weasel's topic in Bulk Orders
There's some prescaler in the RCC registers(Reset and Clock Control) for all peripherals Clock Source. Those registers are also set in mios32_sys. For the Timers clock this Prescaler is 2, means Fcpu divided by 2. Then you have to take it in account in your calculation... TIMER_PERIOD = (MIOS32_SYS_CPU_FREQUENCY/2) / TIMER_FREQ Datasheet is your friend for that ;) -
LRE 4x1 breakable RGB LED-Ring/Rotary-Encoder PCB bulk order
Antichambre replied to weasel's topic in Bulk Orders
It needs something like: 7 NAND gate - 2x 74HC00 3 D-type FF with Set and Reset - 2x 74HC74 Clock inhibit is not necessary. -
LRE 4x1 breakable RGB LED-Ring/Rotary-Encoder PCB bulk order
Antichambre replied to weasel's topic in Bulk Orders
a 74HC165 is a 8 inputs IC with some flip-flop you can recreate the same thing but for 3 inputs only. Check how the 165 is made internally you will understand ;) -
LRE 4x1 breakable RGB LED-Ring/Rotary-Encoder PCB bulk order
Antichambre replied to weasel's topic in Bulk Orders
@FantomXR, You can maybe use some small flip-flops on each encoder board to get a 3 bit shift register, no waste of bit on the SPI data, the enc board will be divisible with all breakable part usable. BR Bruno -
...Remains 5 now. ;)

LRE 4x1 breakable RGB LED-Ring/Rotary-Encoder PCB bulk order
Antichambre replied to weasel's topic in Bulk Orders
Inconvenient with this approach is the transfer time, there's no random write access, the whole chain has to be refreshed on each change. There's not too much data to send but the NRZ protocol is very slow, for a 64 chained led it needs 4ms for the whole refresh this is already a lot of process for just 64 led, less than 2 rings in your case(36led/ring), notes about that ,36 is not a good number to deal with memory, using 2n is always better for coding... But this deserves to be tested and could be enough for a dedicated application which has not extra/other heavy processes. best regards Bruno -
OLRE16 with Lattice CPLD as Clocking/Addressing interface
Antichambre commented on Antichambre's gallery image in Members Gallery
Yes, the number of mux lines is settable in the TLC, it will adapt its addressing cycle and memory use depending on that value. There's a resistor connected to TLC which has to be cosen depending on your led, and a lot of registers for color balance, luma, ghosting etc... Homemade with my cheap and chinese CNC router, bit is 0.8mm 1 tooth alu and I use water+soap to help milling(this is the trick). I use black pmma for mask and translucent white for led is a trotec product -
OLRE16 with Lattice CPLD as Clocking/Addressing interface
Antichambre commented on Antichambre's gallery image in Members Gallery
It's PEC16-4015F-S0024 . some more information in the dokuwiki... Yes it's better in real, always difficult to take picture of RGB stuff with an iPhone ;) Brightness is enough for my taste even with the plastic mask and window, the window is made with special pmma, led were ordered form china, i can share contact, here the datasheet Yes I did it manually, it's an ant work. No update for the moment. No schematic shared for the moment too! ;) Best regards bruno -

An old picture of the ili9361 driver testing, this 1,8" RGB TFT has 160x128 pixels, it is connected in SPI 4wires to the dipCoreF4. The module cost 6$ at buydisplay!
