Title: ErgoDOX - add Lights/Backlight to it!?
Post by: Phenix on Tue, 19 January 2016, 10:40:11: Hello.

cause of the drop Im tinking about getting one
https://www.massdrop.com/buy/infinity-ergodox

But is (on the board in the drop) the possibility to add leds?
I don't need RGB, but one colour would be helpful

the only stuff I found about that:
https://gist.github.com/datagrok/8130501 (https://gist.github.com/datagrok/8130501)
https://www.youtube.com/watch?v=IizBnpjGzOw (https://www.youtube.com/watch?v=IizBnpjGzOw)
and in one manual it was mentioned but not really described. Please help me!

Post by: plainbriny on Tue, 19 January 2016, 16:42:58: Based on the FAQ and the PCB, the infinity ergodox supports backlight led, and the original ergodox does not.
However, I am not sure whether this drop includes led, or whether there's an option to choose key switches with pre-assembled led.

Post by: Vimto on Sat, 23 January 2016, 09:28:27: The PCB supports LEDs it's in the discussion, but it's impossible to find in Massdrop Discussions because there's no search.
There aren't any LED's provided with the drop, and no options for switches with pre assembled LED's on the drop

Diode 1N4148W

(see here)

I don't see, where you're getting, that those are light-emitting diodes. In fact, they aren't.

Post by: Phenix on Sat, 23 January 2016, 18:42:39: I wanted to use them for backlight together with Vortext doubleshot PBT backlight keycaps.

Or do I need some other? Thought they would be right cause of falbatech listed them

Diodes are to direct the path of the current for the switches, you'd need resistors for LEDs.

I think you're getting confused between diodes and light emitting diodes.
Diodes are like Steezus said just to ensure current only flows in one direction.
LED's (light emitting diodes) are what you need to get lights under your keycaps

LED means light emitting diode.
Title: Re: ErgoDOX - add Lights/Backlight to it!?
Post by: Phenix on Sun, 24 January 2016, 07:20:53: so the board is able to power all leds (total ~70-80)?

Can someone sent me a sheet of paper with the layout on it? (want to check if my hands are too small..) thx

and the switches are inversed like all proper backlit keyboards are so that the leds are at the top

Post by: Yggdrasil on Mon, 02 May 2016, 10:41:45: That looks great Glod! I just ordered my first Ergodox with Zealios today and would love to get a similar look. Which type of LED should I use?

And I suppose I'd have to pick my desired color as well, since the Ergodox doesn't appear capable of driving RGB LEDs, right?
Title: Re: ErgoDOX - add Lights/Backlight to it!?
Post by: Data on Mon, 02 May 2016, 13:49:18: The Infinity ErgoDox isn't wired for RGB LEDs. They're not supported in hardware or firmware. You're limited to single color only.

I'd suggest 2x3x4mm LEDs. I get mine from a Chinese vendor on AliExpress. You don't need resistors according to HaaTa -- the Infinity PCB already has a single resistor for the entire board. So just solder LEDs after switches and go.

Still too late, meanwhile I got an normal (non backlit) dox with clears :)

Forgive me if this is a stupid question: But couldn't one use different color LEDs to get a RGB effect or can you only use one color?
Title: Re: ErgoDOX - add Lights/Backlight to it!?
Post by: Phenix on Tue, 03 May 2016, 00:54:08: You can, but you need resistors (different ones for different colors)

[size=85]typos due to my tiuch screen are possible[size]

Interesting. Did you run into any issues dual-populating the LEDs on the top and bottom? I was thinking about doing that myself.
Title: Re: ErgoDOX - add Lights/Backlight to it!?
Post by: Khuya on Fri, 06 May 2016, 17:57:35: I am not an expert, so I tested them before soldering. Some of the other colors would turn off the front led such as red. But blue, white, and cyan seems to work together fine. Been using it for 3 days since i did that and haven't found any issues. I had to use SMD led for the bottom due to spacing issue with the back plate.

how is this working out so far? any issues? would you mind, in case it's working great, pointing me at the right SMD LED part? thanks!

The whole thread appears to be about the ED Infinity, which is distributed only via Massdrop.
Title: Re: ErgoDOX - add Lights/Backlight to it!?
Post by: dantan on Wed, 12 April 2017, 11:54:56: This has confused me. Is there a non-Infinity massdrop version? Is that version older?

If I want to buy an ergodox, sometimes I see the price looks good but no one wants to buy. I remember seeing someone put an ad for $120 ergodox and it wasn't taken after a few weeks. Am wondering if there are 'better' and 'less good' or 'older and unimproved' versions.
Title: Re: ErgoDOX - add Lights/Backlight to it!?
Post by: davkol on Wed, 12 April 2017, 13:03:21: ErgoDox Infinity is a keyboard _entirely_ different from OG ErgoDox (https://www.ergodox.io/); it only has the same layout and—somewhat confusingly—the name. Its feature set is different and not necessarily better. Massdrop has been selling it instead of OG ErgoDox since 2015, probably because it's cheaper to mass-produce and has more gimmicks.

How do you tell them apart? If an ergodox has no LCD screen does that mean it is an OG Ergodox?

Post by: dantan on Wed, 12 April 2017, 13:15:56: I kinda want to be able to figure them out before I buy. The folks selling don't always seem to know what they are selling.

Post by: davkol on Wed, 12 April 2017, 13:21:03: Infinity uses surface-mount components (including ARM microcontroller), has the displays and doesn't support 80key layout.

What if no display and has a teensy and navy blue PCB? What model would that be? I'm looking into buying one locally but the seller doesn't seem to know.

Hi dantan,

The Infinity Ergodox is only available from Massdrop. You might find other users selling them used, but, to my knowledge, there is no vendor that sells the Infinity PCB at this time. Chances are, if you're shopping around for ergodoxes, you're looking at the original ergodox, which will require soldering some components (teensy, I/O expander, ports, etc). The colors of the PCB will vary, but they will cost you somewhere between $25 and $50 for a pair.

I have used both versions of the ergodox for over a year each, feel free to PM me with any questions!

Teensy implies OG ErgoDox. Massdrop used blue for PCBs, back when they carried OG ErgoDox.

Post by: ge61ta on Sun, 02 July 2017, 10:16:28: Hey guys ! So first of all I'd like to apologize if I'm not that familiar with the topic, but I bought an Ergo dox keyboard off ebay. It doesn't have the LED screens, so I guess it's a standard edition. So, I've been wanting to put LED backlighting on it, but can't seem to find any proper HOW TO's on the internet. I actually don't need a full tutorial on it, I just need a picture of the location on the PCB where I need to solder the LED's. If anyone of you can help me out, I'd be really grateful.
Thank you in advance !
Cheers !

Post by: Findecanor on Sun, 02 July 2017, 12:56:28: Unfortunately, the original ErgoDox does not have support for backlight like the Infinity ErgoDox does.
I have seen a couple people's attempts at adding LED strings in-between the keys or fiberoptics but those are all very custom custom and the result has not been nearly as good as a real backlit keyboard IMHO.

Post by: rowie on Sat, 26 August 2017, 11:06:29: I'm getting impatient waiting for my Infinity Ergodox from Massdrop since there is now a delay. I do want "hot-swap-able" LEDs and so I ended up ordering those SIP sockets. All this time of waiting I did do a little reading about how to use SIP sockets for this model here:

https://geekhack.org/index.php?topic=51792.0

I ended up ordering a short SIP accidentally, but I did order some long leg SIPs just to make sure.

As i'm learning about modifications, I did encounter the topic on "holtites," (enabling hot-swap-able switches) not sure if anyone as of yet was able to get them to work on the Infinity Ergodox. This would be so ideal for me since I'm not sure if i'd like the Zelio tactile switch I chose for this drop since I generally like blues and greens.

I also invested in a good starter soldering unit as recommended on the I:C website. I ended up with a Hakko starter set. I got my LEDs, and I went with a 2x3x4 and it looks flush so far on the switch. I also went with the recommended solder from the Input Club website.

Hopefully Massdrop will ship out all the units next week. For now i'll just continue to do read more as usual, time to brush up on the programming aspect, i've been procrastinating this for awhile now.

looks good.

An easier way is to use surface mount, and angle the cut of the acrylic so the light scatters downwards !!

actually, your way is probably easier, hahahaha..

A HARDER way would be.. hahaha

Post by: rowie on Tue, 26 September 2017, 23:34:06: Checking back with this thread. I really love my Infinity Ergodox. It has become "my preccccccious." I tried finding a purple LEDs that don't look like magenta. I went with UV purple and I like it. Although it is the weakest when it comes to brightness. I definitely am excited to try white LEDs as I'm sure it will give me more pronounced under-glow(thank goodness I installed SIP sockets to be able to change my LEDs to match keycap sets). For now I get a little bit of an underglow in the dark. I'm glad I went with the purple Zelios since it has a clear housing.
