RE: MakeVember - Automatic Headphone / Speaker Switch

Hmm ... an interesting hardware-oriented way to solve the problem.

I personally used to have multiple sound-cards installed with a speaker/headphone attached to each output and re-route my audio in software as required. Since I upgraded to an Asus Xonar Essence STX, it has an internal relay that switches between headphone and line-out, controlled by a software applet. Before this, I used to plug and unplug things manually, but found that the jacks would wear out which was bad news!

Nice ingenious way of switching over to the headphones.

Kind regards

Added documentation concerning the next iteration, called Flashlight 'B' to the main body of the blog post.

Great idea. It is good to see a practical use like this for an ePaper display. Your logo is a great touch.

Awesome project. This is something that I am going to try and implement soon, ideal if your going to a conference and should serve as a great ice breaker.

Great idea.

I did get mine out but had issues with the image conversion, so might need to see if your guide works for it.

It's amazing how long the image stays on the screen.

Mines been in it's box for 2 years or more and is exactly the same as it was when it went in there.

Great ! I searched for a while e-ink screens time ago but I have not found nothing at a reasonable price [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-02436bea-45bc-40de-97e4-e235740e8a5f/1512.contentimage_5F00_1.png:16:16]

I made some progress with a dual XM-L2 design, I'm hoping this one is around 600 lumen ballpark, with just slightly more current consumption (perhaps 1.1A at 4.5V). This uses the TI LM3410X driver chip. There is also an 'Ext' port on the PCB for connecting up an Arduino or whatever in future, for providing dimming.

[View:/resized-image/__size/776x340/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-e0d6062f-c110-4f76-a11a-4f1f8d1eff81/4010.contentimage_5F00_185507.png:776:340]

For the LEDs, I've made a 3mm hole for soldering a copper rod, if it works then this is a super-cheap (and easy) way of getting the heat out.

[View:/resized-image/__size/770x649/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-e0d6062f-c110-4f76-a11a-4f1f8d1eff81/6813.contentimage_5F00_185508.png:770:649]

The rear is just copper, for a bit more cooling. The two side holes are for attaching the reflector (the same part number as mentioned before), it isn't designed for this LED, but it looks like the XM-L2 dies are at identical height to XP-E, and the angle for illumination spread is near-identical too. To make the reflector fit, the hole at the rear of it will need to be drilled to 5mm.
