My entry to the scratch built contest.

Giveaways and Contests
12

yup posted a bunch of pictures :slight_smile:
a bit more progress!

13

code is ready for testing. it does work with a small testing led… so onward!

14

That is awesome. I wish more big ass lights came with this. No BS light bars or color changing leds. Just a display. Simple. Good job :-)

15

I’m confused, I dont have a display in this build, not yet anyway… just a simple regular led that glows at the same time as the main led.

was pondering putting a small lcd or oled or 7-14 segment led display.

16

Ain’t nothing wrong with a PVC build. I know there are a few fans of it here. Me being one. Check out my holy hot spot Batman thread for proof.

Looks like this will be the most advance build FW wise, which is where the real future of lighting resides. Keep up the good work. :slight_smile:

17

thanks, just checked my pwm freq with a ’scope. and its around 4khz… is that good? I can prolly go up to maybe 10khz, possilbly :slight_smile:

18

Me too! Looking like this will be interesting. :smiley:

19

thanks for watching :slight_smile:

20

Sorry, I’m not a good judge of PWM. Traditional SRK’s don’t even bother me. I only avoid it when working under the hood or with other dangerous moving machinery. 4K sounds good to me though.

21

well I don tthink someone (me) will use this under the hood or under a car :slight_smile: well I could but its kinda overkill for that use :slight_smile:
anyway. maybe tonight or tomorrow I’ll get everything wired together and post some short videos of it actually doing something before I get some pvc parts to try and package it up :slight_smile:

22

two videos of the guts working… now to build a case :slight_smile:

23

I'm up to wiring as well. When do you think you can come around?

24

what help you wire yours up? naw… :slight_smile: I gotta build my case yet…

25

I spend most of my time on the host and as little as possible on the driver which is silly given the driver is the heart. Nice to see it being done the other way around.

26

I think I spent maybe 10 mins total on the code. more time was spent attaching wires to things and connecting the wires together :slight_smile: my code is simple… about 10 lines long…
unless I decide to put modes and or a indicator/display of some sort on it.

27

A lot more in there than just code but even your minutes spent are more than I do.

28

thanks I think :>

anyway… tomorrow I hope to get some of the parts to start making the case… and a power switch :slight_smile:

29

Bump for update in first post, new photos will be posted shortly

30

Those couple of leds are really pumping out the light. Have you had extended runs yet? I was just wondering how well the heat sinks work.

31

not together no… but the cool white heatsink does get warm… not hot but warm, the driver… very warm almost hot… so there will be ventilation, will mount a fan to each “cannon” I’m pondering calling it a light faucet… and maybe getting a waterfaucet handle for the pot :slight_smile:

when pwm’d the drivers and heatsinks dont get warm really… under say 80% full…

I’ve got a handle mounted, mounting main power switch shortly… then I have to drill vent holes for the led heatsinks… then figure out how I’m gonna mount the fans and cut vents for those :slight_smile:
then I can cut holes for the wires that have to go between each pod… then attach the pods together and start wiring things together, taking lots of photos as I go… :slight_smile:
