The I "C" Red Battle Royale LPF Contest

I know I don't know when you thought of it =p Just saying we independently came up with the idea, so they are both considered original.

It is a cool laser host !I think a lot of us had thought of make a laser from it I know I did .
I would like to find were I could get the sound board from some of the toy lasers.

Hey now. You have no idea when I "thought" of this lol

Yours will be red AND way more advanced than mine. I dont have the know how to get those stock buttons to work and such. I really look forward to your TNG phaser

IT LIVES!



So it works. At least almost entirely. I accidentally ordered the wrong package type for the binary counter, but that part is just desert - the meat and potatoes - the DAC - works just fine. If I apply a high voltage to the pad where the third bit outputs, corresponding to 100, I get approximately 1.7A out. If I apply a high voltage to the first bit, i.e. 001, I get approximately .5A out. If I apply a voltage to the second bit, 010, I get about .8A out. Any combination of these will literally just add the currents. So if I have the binary counter outputting 110, it will output 2.5A. If it outputs 101, the driver will output 2.2A. So, my current ranges are:

001 - 0.5A
010 - 0.8A
011 - 1.3A
100 - 1.7A
101 - 2.2A
110 - 2.5A
111 - 3.0A

So there are all my modes Who needs programming? Heh.

Also, another good bit is that the little MOSFET there, at the bottom? That is the switch. So no high current needs to go through ANY of the buttons! Wewt! Also, those four pads at the top are supposed to control the binary counter, and it will work - I've made sure of that. When a switch connects the top two pads, it'll increment the current by one step. If a switch connects the bottom two pads, it'll decrement the current by one step. Neat, huh?

Anyway, I am going to order the CORRECT binary counter today and hopefully get it by the end of the week so I can get it wired up inside the host!

That's just brilliant Wolfman! :gj: Really clever how you bypassed the high current issues with your switch and your solution to adjusting your currents :beer:

Really coming along nicely, Thanks for sharing

I'm kinda super proud of this ^_^ Once I get the driver fully finished and integrated into the phaser (connected up and everything - just leaving some free leads to attach to a test load for testing purposes), I'll need a machinist

Plenty of time to get things set. I don't think you'll have trouble proving the design is viable and worthy of being chosen to see completion for the final Battle Royale

If you're just anxious to see it done sorry You should be really proud.

I'm just anxious to see it done XD I have high hopes for this competition, and I want to get this to become a working laser!

It looks like you have the foundations set pretty well already. It's good that it all fits in your host too

I've hit a brick wall...HARD! The drivers I've made all don't work properly. I've made 4! Can anyone be nice enough to point me in the proper direction of making 3-4 amp drivers? Frustrated! My design is flawless besides the driver problems.

Just use a big parallel driver. Or use one LT1083.

Dude, that driver is awesome!

I love the DIY DAC

Thanks I'm super excited to get this working. I'm just imagining being able to press two buttons to adjust the power! Ermagerd.

The joys of seeing a little circuit you created all your own come to life are unmatched. Especially if its the first try!

I just realized I have some PM from you I never replied to haha. That was a while ago too! Sorry

Theoretically couldn't I use an lm317t with a .6 ohm resistor?

Ben, that's exactly the feeling. I'm sure you know it

And cantthinkofone: that won't work. LM317s can only supply 1.5A at most.

Damn. I tried. Wolf imma just message you rather then spam up the thread.
