/diy/ - Do It Yourself

how much time and money do you want to invest in a gadget which will bore you after 15 minutes? I'd suggest you make instead one of those globes with sparks inside, that are attracted to your hand. they've been shown to attract attention in young males for 17.5 minutes, so you get 2.5 more minutes of enjoyment than the Ambilight.

Hey, you know what would be cool? If you could just ignore my thread instead of shitting it up trying to prove how edgy you are, that would be really cool.

more wise than edgy. been involved in lots of projects where the final reaction is, "Okay, it lights up, what else does it do?"

>"Okay, it lights up, what else does it do?"
Lighting up is all it's supposed to do, I don't understand what you're getting at. Do you think Tesla/Eddison where thinking "Okay that's cool but it doesn't do anything else, what a waste of time" when he made the lightbulb?

pick 3, then tell your mom I said hi...talented /diy/er

monsters are afraid of light, so bulbs are infinitely useful. but the Ambilight, like many gizmos, sound like a really cool idea when you hear about it, but quickly become disappointments when you see them in action. If you can imagine yourself still getting excited after 3 months coz your TV has a variable background glow, you may be the world's most boring person.

From my experience with making CPLD/FPGA based systems- I don't think this is going to be as easy as you think it will be. What sort of engineering degree do you have OP?

It's not about the wow factor, it's just a neat gizmo that I would have fun figuring out how to make.

Computer science, but I'm still pretty comfortable working with digital logic.

constructing the logic is the least of your worries. How much experience with electronics do you have? It's more relevant to understand electronics than being able to program with FPGA's- making a program which theoretically does what you want is pretty simple- or at least not much more difficult than programming the same thing in a higher level language like C. when it comes to simulation/testbench/pin fitting/pin output/input modes and timing analysis is when things (we're still only on the software side) get tricky

I put Ikea LED strips behind my tv (pic not mine, but looked exactly the same). I plugged it into my receiver so it turned on and off automatically (but obviously the intensity didn't change).

The first problem was, my tv was on a stand, and it created a silhouette of the wires and stuff under it.

The second problem was, it provided a constant visual reminder that I was watching a television. I want to get engrossed into the movie, I don't want to see my television bezel.

Maybe you would like it more than me, but I removed it after a couple of weeks.

I'm used to working with micro controllers too, I don't think FPGAs would be much more challenging.

they are. There's a reason that even though an FPGA is much more capable than a MCU - and comparable in price for capability that you see a dissimilar amount of hobby level projects using mcu's/FPGA's. They are a lot more involved. Microcontrollers are simple business. What design software are you using?
