Title: Harbinger One with Demo (first etch)
Post by: pryde on April 18, 2013, 03:09:26 PM
OK finally here is a Harbinger One fresh off the bench. After much troubleshooting with voltage problems it is complete and sounds just fantastic. I powered with 9v and used the filter pcb with 220uf caps (omit and jump R54 if doing this). I made a reflective sheild for the lamp/photocells with an armor-all plastic cap and it fits perfect.

Also the first pics did not have the yellow pulse LED but I went back in and installed it after I got the voltages figured out (thanks Madbean for the help) The pulse LED works great. There is a closeup photo of it as well.

This is also my first enclosure etch! I think it turned out great. I did practice a little on some scrap aluminum to get the timing/technique down. I used a samsung printer with HP presentation paper and it worked perfect. This one is for a local musician who is going to be stoked. I will build my own soon.

There are some demos you hear where you think yeah, that's cool, and then there are the rare ones that you don't want to stop. I think you know which category yours is in Pryde. Fantastic work and playing! I'm very proud of you!

awesome etch!

I'm jealous of the guy getting that.
fortunately I got my pcb in the post today ;D

Thanks everyone for the very nice compliments, means alot from all you excellent builders here. I put this one in the April contest, just cause I'm very proud of it. There are so many builds here that inspire me to keep pushing my creative envelope so its a win-win either way  :)

I will be glad to share any tips from my etch even though I am new at it so YMMV of course  ;D

Post by: whitebread47 on April 19, 2013, 05:44:46 AM
Your build is quite worthy of an entry in the build contest IMO.  And yep, the only thing that pushed me past a bare enclosure with sharpie labeling was all the gasping in awe I've at the marvelous builds of all the resident wizards here (yourself included, of course). 

They raise the bar - I just try to catch up!  ;D

I would love to hear about your process on etching. I have attempted it once and was not very susessfull with a deep etch like yours. Any info would help. Thanks

Hey Pryde, im half way through building this. Quick question, does the rate LED stay on when the pedal is bypassed?

Great etch and the playing is first class...got my board the other day, makes me want to get it built up even quicker.
Well done Pryde ;)

@ selfdestroyer:

-I used HP gloss presentation paper printed with samsung laser printer at 300 dpi
-Baked on the transfer with wife's iron using highest setting for AT LEAST 15 MINUTES. The enclosure was extremely hot when done (hot enough to make a blister I know :)
-Let this soak in water for 15 minutes and gently removed paper/wet pulp from surface. This took the longest and used only light rubbing pressure with my fingertip to teese off the material.
-Painted nail polish around edges very thick to protect alum on sides
-Used blue painters tape and taped on small toothpick off-sets on each corner on the face of the enclosure
-Used Radioshack ferric-chloride ~1/8" deep in bottom of flat, plastic plate.
-Sat enclosure face-down in etchant (toothpick offsets keep it slightly hovered into etchant)
-Mild agitation for 5 minutes and be mindful of aluminum temperature. If it gets hot to the touch, remove it and set it in plate of water to stop chemical reaction, then resume etching again for another 5 minutes, repeat until you clearly see relief in the aluminum.

This one took about 15 min total with this process. I think the difficult part is knowing when to stop for good as the etchant is reacting and its hard to tell how much it has eaten away

Awesome, Its the same process I use for PCBs for the most part as I laid out here. http://music.codydeschenes.com/?page_id=1388 (http://music.codydeschenes.com/?page_id=1388) it looks like we use the same paper and iron. My wife gave me her iron when I promised to buy her a new one.. lol

I will give it another go this week and see what I can get. Thanks for taking the time and documenting that out. I appreciate it.

just got a couple of quick question s about the BOM, theres no r48 right?
and the 22ohm resistor in the shopping list isn't needed?

No, Thank you for testing my method on an enclosure and showing that you can get some awesome results that way. But we all know its not the process that makes good results always, its the skill of the person.. and you gots skills lol.

I will be making a tutorial like it did for the PCB etching when I get a good system down. You also gave me some great ideas as well (toothpicks to help the enclosure to not rest of the bottom of the rubbermaid container)

I really hope to try this again this week and see If I can get some results like you did.

Great job man,

what enclosure do you use ?

Also, do you change something on the layout ?

Thx :)

Mucho kudos! Your etch looks awesome, perfect aesthetic. And that demo is amazing!! Really good playing and great example of the effect in a situation where it shines.

Could you tell me what kind of pots you used? I have heaps of board mounted ones with long stand offs, but I'm guessing your using the ones with short pins? I can't see it fit otherwise.

I used pots with short standoff pins. The box is actually the "deep" 1590BB as I wanted the extra depth for the lamp and photocell cap. I would have had trouble putting this in a standard 1590BB

Here is the deep one from smallbear that he calls the "125BB" size:

I'm about to build this project for use with a one spot.

As yours works well i'd like to follow your advice. Quick question though. You say you used 220uf caps on the filter board. Is this correct? the build doc calls for 470uf caps there. Did you try those and decide that the 200uf worked better?

Your build looks and sounds awesome by the way :-)

Actually I ended up removing the little filter pcb and went with just the main board filtering. Use just a 220uf on the main board (C22 I think) and it provides good filtering with a one-spot 9v adapter. I have done it this way on both harbinger one builds with great results.
Good luck. I will be glad to answer additional ? if needed.

Thanks very much. That's very helpful. I was confused because the pics you posted still had the extra filtering board in there.

That is amazing work.  The graphic is perfect for etching and the etch is outstanding.  I already kind of wanted to do a Univibe and now I kind of want to etch something too.  Beautiful!

The guts and sound are spot on too.

Excellent roadmap to success (I hope).  Did you do any protective coating or anything?  Or just leave it to age gracefully?

And, how did you mount the LEDs on there?  I like how you can barely see them until they're on.  Much prettier than my big ugly bezels.
Title: Re: Harbinger One with Demo (first etch)
Post by: pryde on June 06, 2013, 01:34:50 AM
@das234

No coating on it. just left it bare after etching. I think some people shoot clear over it to protect in and help it pop more so it might be worth trying

The LED's are just 3mm waterclears just stuck in the drilled hole with a dab of superglue, easy-peasy  ;)
The key is to use the correct bit where the LED will seat into the hole very tightly then a dab of glue and your golden.

Post by: das234 on June 16, 2013, 05:19:45 PM
Do you use/reuse the same etchant for aluminum as you do for copper?  I've read that you can reuse it on copper but not on aluminum for some reason.
