I got my Pocket back today with a 220ohm resistor added in. I played with it on battery power for about an hour or so earlier and didn't find any of the dreaded dimming problem. The light panel is a bit dimmer, but everything else seems to be good.

About the resistor, I'll try to find someone in the area that can help me fix the issue, but I'll try running it with an adapter.. it's weird though, if the backlight pulls too much power, the brightness should always be the same, right? or does it have something to do with LSDj running..?

I was assuming that it's not the light dimming, but the actual LCD screen. When you hit play, it has to pull more power to start the sound and with the backlight draining a lot, the LCD goes faint, much like it would with low batteries.

I didn't find the problem with any games, so it could be LSDJ... but I'm pretty sure it uses much more CPU power than a standard game anyway.

Also, I had dimming on both EMS and DND carts. It was much more pronounced on the EMS cart, though.

The problem is that the backlight pulls way too much power for the 2 AAA batteries the Pocket runs on. The way to fix it is to add a resistor. According to this thread (http://chipmusic.org/forums/topic/12898 … -software/), Thursday Customs recommends between 100-220 ohm and there may be some guess work involved.

I actually just had to send my Pocket back to a modder who did mine and he put in a 220ohm one. I haven't gotten it back yet to check how it works, but I'd bet the LED colors that drain more power (white, blue, green) probably need more resistance than other colors. But I only had problems when using LSDJ. The contrast would always change as soon as I pressed start... though it didn't seem to happen as much with the AC adapter.

should i create an option with an included trimpot on the product page?  wouldn't be hard to do

Might as well... everyone likes a one-stop shop!

I'll probably stick with the 5 pack. I don't know what I'd do with 20 of them!

Does it matter what wire I use from the trimpot to the board? Can I just pull some speaker wire or something?

Okay, I think I found them:

I was hoping to avoid modding the case, so I'll probably find the sweet spot and leave it there. Thanks!

Is the red wire in your images coming from the frontlight? It looks really long!

Where did you pick up those trimpots?

I'm about to embark on the first mod I've ever done on my own and put a frontlight in my prosounded GBC with Kitsch-Bent's kit.

I'm doing the basic non-LOCA version of the mod, because all I use it for is LSDJ, so as long as it's visible in low-light, I'll be fine.

However, I'm not sure what kind of resistor I should get to dim the frontlight so it's not completely washing out the screen. I noticed Kitsch recommended a 1k ohm trimpot so the resistance can be dialed in, but I was thinking maybe a 500 ohm resistor might do alright, since it's right in the middle of the road.

Anyone else find what the sweet spot number is?

Hey folks,

I had made some spooky sounding chip before, but I'm really proud of how these tracks turned out.

Also, there's only 4 copies of the lathe cut 7" record left! Get one while you still can!

Thanks! Glad you enjoyed it!

Also, edited the original post to add links to Spotify, iTunes, etc.

My new single/EP is out now. It's a bit different than the other stuff I've done, most notably being the first time I've done tunes with a 2xLSDJ setup and that I was going for a Goblin-esque horror movie vibe.

Like my last EP, FUZZY, this one is coming out as a 7 inch square lathe cut record. Each record is cut in real time and only 10 will be made. They're up for preorder at the Bandcamp page and once they're gone, they're gone.

Here's a music video for the track "Listen Galahad":

Hope you folks enjoy it!

$50 for an EMS 64m card is about right, maybe a few bucks too high though.

$50 for a Drag N Derp is an amazing deal you'll probably never get.

3 track EP drops March 18th at http://portopak.bandcamp.com

Plus, the EP will be released as a 7" square lathe cut record, limited to 10 copies.

Only one more week until this EP goes away, until it's inevitably brought back out next year, because Christmas EPs are just like your mom's Christmas decorations.
