I got the batteries from batteryspace about 8 months ago. I don't think they sell these anymore.

Re: Project SGP-1 *UPDATE 2/21/10*
Well it rained pretty much all day today in OH and what's the best thing to do on a rainy day? OK, what's the 2nd?
Play video games of course. The 3rd? Mod stuff. So that's what I did. I'm 99% finished with Project SGP-1. I just want to add a reset button.
Here's some quick pics I took. Better pictures tomorrow. Youtube video will follow later in the week
Cartridge slot re-wired.

Running Mega Turrican, one of favorite video games.
The thing to the left of the speaker grill is the volume dial. I made up a dirty LM386 amp for audio and it's working pretty good.

Size comparison with the Nomad. I like mine better.

Looks great! The name of your portable reminds me of Stargate.
What happened to your blog? I enjoyed reading your NESp Delight progress but now it's gone.![Sad :(](./images/smilies/icon_sad.gif)

The voltage regulator is the 5V (DE-SW050) by Dimension Engineering. They are about 15 min from where I live so I just went over there and bought a couple. The portable cuts off when the batteries are around 6.45 V. The datasheet for SW050 says min Vin is Vout+1.3V. So they are .15 V wrong.

The electrical tape probably wasn't needed but I was afraid the back of screen would contact the system board.
Case secured by 4 screws

Re: Project SGP-1 *UPDATE 3/13/10*
This weekend I finally had the time to finish this guy up. I added a reset button and a low battery led.
The low battery circuit I used can be found here: http://www.iroquois.free-online.co.uk/lithled.htm" onclick="window.open(this.href);return false;
I got the IC from a really cool place on the east side of Cleveland OH called Electronic Surplus (http://www.electronicsurplus.com" onclick="window.open(this.href);return false;). The part cost $9 bucks, so it's not cheap. But if you are looking for an easy to implement low battery solution I recommend this.
I changed the resistor values from 680K to 800K(330K+470K in series) and from 150K to 168K(18K+150K in series). The led starts to light up around 6.9V. The unit shuts off when the batteries are around ~6.55V (seems to vary a little). This gives me about 10-15 min of play time.
I was able to do some real world tests and the batteries lasted 4 hrs. No bad IMHO!
Youtube video will be posted soon... I hope.![Smile :)](./images/smilies/icon_smile.gif)

Re: Project SGP-1 *UPDATE 3/13/10*
This is simply awesome. Could you provide us LM386 audio amp schematics? That'd be appreciated...
I TAKE COMMISSIONS FOR CNC-ROUTED CASES AND PORTABLES... JUST P.M. ME!
Re: Project SGP-1 *UPDATE 3/13/10*
I think in the datasheet is the schematics that he used, but I am waiting for the answer too.c_mon wrote:This is simply awesome. Could you provide us LM386 audio amp schematics? That'd be appreciated...
