Antichambre Posted September 29, 2017 Author Report Share Posted September 29, 2017 I need it, I propose it, so I offer shipping to and from my home. I hope this will help some to decide and reach this small amount!50/100 for the moment... Someone? Best regards Bruno Quote Link to comment Share on other sites More sharing options...
Zam Posted September 30, 2017 Report Share Posted September 30, 2017 Bonjour Bruno No really need for this now, but for the record I'm curious to know what knob/caps option is available for this ? Best Zam Quote Link to comment Share on other sites More sharing options...
Antichambre Posted September 30, 2017 Author Report Share Posted September 30, 2017 (edited) Everything is from ebay. And from djtechtools Second column are transparent and glow in the dark. All rubber. As you can see they have got encoder knob too. They sent me some samples to try it...

Antichambre Posted September 30, 2017 Author Report Share Posted September 30, 2017 (edited) I will probably use this Led Driver from TI. It's a One Wire daisy-chain with Internal clock and 8bit PWM to relieve CPU. For 0,8Euro each. You're sure you don't want some? ;) Best Bruno Edited September 30, 2017 by Antichambre Quote Link to comment Share on other sites More sharing options...
Zam Posted September 30, 2017 Report Share Posted September 30, 2017 Hi Never looked at this, tks for the pic, seems like lot of knob design today offer transparent option! Truly interesting ;) but sorry no need for this right now Best Zam Quote Link to comment Share on other sites More sharing options...

Using TLC59731 ? One RGB Led, This is 3 channels driver. A 32-Bit Data Packet. 8bits command + 3x8bits(RGB). The goal is to relieve the CPU and facilitate the design of the layout. It requires 3 resistances too, but it's only one line between each driver, between each RGB pot. It's 8 pins SOIC package, not too big or too small. In datasheet page 18, it says "There is no limit on how many devices can be cascaded, as long as proper VCC voltage is supplied."

ilmenator Posted September 30, 2017 Report Share Posted September 30, 2017 I see, doing the $$ math I rather stay with regular encoders - but thanks for the idea! Quote Link to comment Share on other sites More sharing options...
