    Need help repairing Microwave oven

    Noob + MOT = Much bad joo joo. Our advice should be limited to those operations not involving these parts. One flash, you're ash is in full effect. You are where seasoned techs fear to tread

    A Little Delayed in Starting

    Analog and digital grounds are often tied together in many designs. In my approach, I'm just taking into account a few undocumented discoveries about these chips as well as a few other refinements. the use of an input buffer, by way of a TL072, strengthens the signal to ensure it wont sink as I...

    Need Help on Cord repair...How can this be?

    likely the best course of action ... even with sealant super powers, the construction of the cable isn't exactly user friendly

    Need Help on Cord repair...How can this be?

    Yes, the same kind of wire is used in motors, transformers and guitar pickups. It ensures greater safety in this role, but it is a bit more prone to breakage at flex points

    A Little Delayed in Starting

    This is where I am at with mine. The power distribution block. Using a 5V linear regulator and the MAX1044 charge pump, Input 9V via barrel plug ... Outputs -9, 0, 4. 5, 5, 9 and 18V -9, 4.5 and 18 taps will service the analog TL072 based input and output buffers. With 13.5+/- to operate in, it...

    A Little Delayed in Starting

    It should not matter too much, as they are in parallel. it leverages the traits of specific types of caps. the 100 holds a charge while the .1 shunts spikes to ground

    A Little Delayed in Starting

    for both of us hopefully. I don't have that big of a jump on you to be honest. I have the power distribution section done, but I am still combing the parts mine in search of victims.

    A Little Delayed in Starting

    how about 3X AA batteries? (1.5 X 3 = 4.5V) It'll get you started until you migrate to LM7805 regulators. then it's pedal board friendly in 9 out 5

    A Little Delayed in Starting

    Part right. Electrosmash has documented the chips quirks. Pin 6 is the primary means to adjust clock speed ... AKA delay time. Fast clock speeds (short delay times) cause it to choke if powered up while set to such speeds. Since a reverb would be such an application ... the sucka gonna hang...

    https://www.electrosmash.com/pt2399-analysis Further information of the PT2399 ... You shouldn't need much more than the datasheet example until you discover some of the quirks ... then the pin 6 strategies may come into play. I have a dozen of these chips and sockets, as well as some...

    Leaked batteries in Tascam DR-07 digital recorder

    "Switch" becomes a little bit fuzzy in these things as the real switching is done by logic and the buttons you interface with are kinda like suggestions. While possible, it's unlikely that any button has failed. Probability rides on a gob of battery vomit stuck someplace you cannot see it...

    Just When I Thought it was Going to Be Easy

    At least a few. these used to be most commonly built with bucket brigade delay lines.These would take a voltage sample in an internal capacitor, and use a clock affair to shift the sample to the next cap in line while taking another voltage sample.this would continue along a line of capacitors...

    Leaked batteries in Tascam DR-07 digital recorder

    as I understand it, the LCD's back light is working, but the LCD layer itself is comatose ... likely due to nothing else coming alive Some of these boards are certainly not for the unseasoned home gamer. I'd just assume it has a fair bank of effects courtesy of a lovely TQFN package chip in the...

    Leaked batteries in Tascam DR-07 digital recorder

    I guess you could be more vague. For this, we like pictures so we can better form theories about what caused the result. But then ... The DP- 32 has some respectable horsepower

    Seems like an orderly method is beginning to emerge.... Wanna try a delay next?

    The mobile power bulges

    its not that uncommon. I don't do it, but the theory goes that the salt water will discharge the pack while it's kept from ignition by the cooling action of the fluid. there really isn't a great method for dealing with this in field

    The mobile power bulges

    in a few of these cases, transporting the battery is an even worse practice. they go in cool and rectangular .... and come out round and steamy. after which point, nobody want's them near their vehicles.

    The mobile power bulges

    Some RC pilots submerge packs in a bucket of salt water as a means of safe destruction.

    Yup ... You must include duty cycle into this figure
