This is the chip I need to program to unbrick my wifi router: I wonder if anyone has used a raspberry pi to program an ONFI 1.0 flash chip Lawncat: if so, you could put the probes on the switching element in the power supply and figure out what its switching freq is Lawncat: do you have a multimeter with a Freq option? That kind of number is very much in line with SMPS switching If the primary signal (top) is ~ 10 kHz, then that overlaid signal is (evidently) 15-20x that (it seems to have 20 oscillations per 1 overall cycle of the main signal) Heston: I would guess that it could be switching noise. Heston: spikes at 20k and 40k though, which are both higher harmonics of 10k the primary singal in the FFT seems to be at about 800 Hz Heston: weird that the primary signal isn't in the FFT. Heston: I wish i could tell you, I think it's tek in general, but I'm really not sure Tgeeky, for thos Tek probes, will I be locked to specific models or just Tek in general ? You are getting a good enough sample, try to FFT it Well it does lok pretty low frequency.my sampling rate is only 96k Tgeeky, right ok, so if you can set the delay individually for each channel, why would it be an issue? Lokust: looks like a triangle wave where have the triangle is noisy as fuck

Well, they re being sold from a business apparently and I have the guys professional linkedin accountĭoes this look familiar at all, tgeeky ? Heston: you can always compensate for delay in a scope Heston: the problem is you can't test them, so you will have to sell AS IS which, at this point, might be happening to you :O They're worth about double what im going to pay Heston: remember 3/4 GHz probes will be active so you will be tied to whatever interface they have with whatever brand of scope. Heston: you're getting 3/4 GHz probes? Don't you not yet have a scope? I think the issue is that i need some sort of divider network or else a single resistor will give me 5v at the g8 and that's too much to be useful different model will have different delays, which can cause issue when you scope stuff Heston: look for the attenuation on those, it probably do not have x1Īnd also, different attenuation have different bandwidthĬasper, well they're Tektronix P6158 and P6249Īlso, if you use them simultaniously.

It prints with human blood as ink, and human skin as parchment Im getting a wicked deal on a few of them, 2 are supposedly new What should I look for if im buying used 3/4ghz probes? I found one of these at the thrift store near me Im trying to figure out if your shit makes sense ZigggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggyĪnd is this an N channel Mosfet you are using? Resistor from Drain to gate ( high resistance, ie 1M )

I wonder if I should look for any other failures on the main boardĪlright i need something more concrete as an inputĭrain to ground? before the resistor? drain is connected to ground in series with the resistor so it would be 5v So if you connect a 1M or higher resistor from D to G then it should self biasĪnd D should be like, I dunno, 2.5ish or something around there Looking for like a 100k resistor to connect D, that middle pin, to +
that's the right-most pin because it's GDS. I want a few electrons jiggling in a wire caused by some external field to be amplified to a level that can be amplified by a darlington that can be amplified by a mic input on a sound cardĪnything with emf.no im not detecting ghosts.im looking for phones in couches Lawncat, so you want some generic amplifier right?
Jsoft: gonna redo it again.oh i was also looking for another one in case i broke this one.if its even possible with any configuration at 5v Too bad it's somewhat difficult to test the parallel chips Well, the guy I bought this from said he flashed these better chips with sanyo's newest firmware for these model tv's Sometime it may be wired internally to some part, used during manufacture for test. Shawn|i7-Q720M: NC do not mean "no connection" but "do not connect". That was while I accidentally 2 pins soldered from the underside connected

When I turned on the tv I did see some tv snow for a second Say that again? You left what pins soldered together? I accidentally left 2 what seems like no connect pins near 1 soldered togethor, is that enough to kill the firmware chip? Shawn|i7-Q720M, Im drinking, but lets have a geeze Can someone look at a datasheet with me and help me figure out something?
