Some pics. I basically just tinned the iron and pressed the wire to the pads. I scuffed up the pads with a screw first though.

You can also see I marred it a bit using too small a screw driver.

nice work shotgunefx.

one wuick question.
has anyone made their own serial cable to falcon connector?

hi all....sorry for double posting...but i had to say this before i forgot...
@everyone who uses their phone for mologogo

i remeber someone saying that one random wrong number would suspend mologogo....

i found out...at least on my boost i415, if you set the call forwarding feature to forward to any number....(it doesnt actually work, at least when i tried) it will not allow any incoming calls.

(i have recieved more than ten wrong numbers in the past 3 days...and its gettting really annoying...so hope this helps someone else.

Hi everyone, was wondering if the Mologogo Generic - Auto Restart Mologog Wiki tip works on the i415. Also, does the app start automatically on power up on the i415 as it does on the i455? I will mostly be using it for tracking, not much internet surfing. Any suggestion greatly appreciated!!

hey tommy, i have a i415, and i use the candy bar style app (made for i415 and other non flip boosts) and i have it auto start on power...
you go on the phone to menu -> settings -> personlaize -> Power up, select power up, and then browse to mologogo.

forwarding the phone to avoid interuptions has been mentioned several times & is even in the first post I think, theres even a # provided to forward it to that gives a prerecorded msg telling the caller something to the effect of this # is unavailable or something...

any better values yet shotgun?

I've been talking to someone about building a board that will power this phone directly off the vehicle battery & restart the phone hourly, but that will involve opening the phone like shown & soldering to the power button, does anyone else think they might be interested in something like this? I'd have to get a batch of 10 for it to be worth doing on a custom board, I was quoted a price of approx. $15 each in that qty. BUT, I just inquired about adding a voltage monitoring circiut that will kill the phone before the vehicle battery, like a good dc-dc supply would, so even if you leave the car for several days it couldn't kill the battery, don't know how much that would add, waiting for an answer, if theres no interest then I'll just have one hand done for me I think...

Well, with my initial experiments, I couldn't get it to work with any value caps I had, but I didn't have anything near the 67uf range, either much smaller or much bigger, then my week went to s**t and I haven't had any time to play.

I did order some 8-pin PICs today though

They don't have an ADC, but might be able to jigg the comparator for low battery shutoff.

cool, are you still shooting for internal after seeing inside

shotgunefx · 06-15-2007, 11:14 PM

Hmm, just had a thought, if you were going to go with the PIC, then you could use an 11 or 12v zener diode installed backwards and a large resistor as an input to determine battery level.

Since it's backwards, current will flow when the battery is above that level, once it falls below it, it won't conduct anymore which would drag the PIC pin low so it knows to shut off the phone.

Don't think so unless I find some free space, it's only one little chip, but an 8-pin DIP isn't that small inside something like that. They have much smaller versions, but my hands are pretty shakey, don't think I could solder em. Also, programming it would be a pain as it wouldn't fit in the ones I have.

would that be precise enough? I guess an 11v might do it, but that might be just a bit low for comfort, 12v would be way to high I think...

Yeah, 12v would be way too high. But 11v maybe not too low. It's not supposed to conduct at 11v, but greater than 11v.

You could always use two resistors in a network to tweak the battery value seen or probably better, another diode in series to drop .3 - .5 volts before the zener, effectively making a 11.5v zener.

I'll take a look, but I think all the zeners I have on hand are 12v or 15v.

edit
You'd have to check the tolerances of the zener in question, but I think usually the zener voltage is pretty precise as opposed to other components which often have a 5-10% tolerance

Why not just power the board from the PSU? When it is on, the phone is on, when it's off, the phone runs on its own battery until it shuts itself off.

turbocad6 · 06-16-2007, 11:56 PM

I want it alive 24/7 & running mologogo 24/7, the hourly restarts & powering it from the car will allow that, I don't want it shuting itself off except for it's hourly restart.

I do want a failsafe though that it could never kill my battery, it will diconnect power before that point, & then the phone would have to shut itself off like 5 hours later as it dies, but if the vehicle is used every day I think it'll be on 24/7 & not ever get to the point of turning off.

disclaimer Well, keep in mind I am far from an electronics expert, quite the opposite, just know enough to be dangerous, but I think something like this could work. Then again what do I know

I think an 11v zener wired to the output of a 20-turn potentiometer would give you the precision you want. You could wire it to a base transistor that would supply the charger.

Something like the following, P is the pot, R2 is just a small resistor to stop P from getting shorted out if the pot get's turned all the way down (I smoked my first RGB lighting doing that

)
