--- Quote from: dietert1 on August 31, 2020, 05:29:01 am ---Why somebody needs to buy parts really cheap? Probably because there is a lack of income. Maybe the reason for the lack of income is using unqualified parts in the past and spending to much time on fixes. --- End quote --- Probably because someone is a cheapskate. I doubt that many of US or western EU residents are so poor and need so many parts that they need to buy 20 NE555 for $1.5. --- Quote ---I mean there are people who started this as a student (when their work could not yet generate income) and missed to change their habits later. --- End quote --- This should be closer to reality. However many people simply like to buy cheap as possible even if they always had the money. |

This is a shock for me. I genuinely thought the buyers of Aliexpress/eBay were 100.0% hobbysts. If a professional buys parts (single components, not semi-finished products) from Aliexpress/eBay for job related development activities, well... we have a whole lot to discuss here about the definition of "professional". I mean, the cost of the risk alone, computed by the time you wait for the shipment, makes zero economical sense. The real cost of the items is way higher than the price tag. I bought tons of stuff from eBay/AliExpress, got my good parts and bad parts, good shipments and bad shipments, but always got the value I paid for. On the other hand I had major issues with Mouser/Digikey as well, but the cost of those issues had already been taken into account in the project. The extra price you pay is compensated by the quick shipping and the prompt support you get from them: unthinkable with eBay/Ali. |

At that time, I was really prepared to receive fake 555 (non cmos version) as they're so cheap, but ended up all being genuine as I rigged up simple oscillator test circuit on breadboard below, and all run and still oscillated at 1.5v VDD, clearly not bipolar version, maybe luck was on me. :-DD |

Them working without detailed testing/inspection proves nothing about them being genuine. |

My philosophy is: if a part works well enough for my purposes, it is genuine enough! :D |
