Can anyone pls buy these

Krups coffee grinders still use through-hole 555 timers. They claimed the vibrations of the grinder was shaking the surface mount components off of the PCB.

I bought the first one in about 2005 or so. Since a new one is cheaper than replacing the blades, I've bought two more since (the exact same model is still available). The first two had the same through-hole parts. I'll check the current one when it dies.

Crazy isn't it - but the cost of keeping and supplying spares isn't cheap, manufacturing and selling new product is far cheaper.

When you replace them do you keep the old ones for spares? - and them throw them away decades down the line

No, I don't keep spares. I am just curious to see the manufacturing technology and the circuit design for what is essentially a delay timer - push the button and the hopper fills over the next 20-seconds of run-time. How complicated can they make the circuit including the stepdown from 120vAC. The answer, "simple and cheap" for some companies and "surprisingly simple because they selected expensive modules" for other companies, and "how cheap have 32-bit microcontroller become" for other companies.

I'm mostly of the mindset, if it comes apart easily, I'll pull it apart to take a look before it goes in the bin. I also don't like repairing things that are used as consumer products by people who expect them to work and fail safely. I know the effort that a company like Krups, Sony, Electrolux put into selecting components, materials, design and manufacturing technologies to insure a failure mode doesn't end up in a fire or electrocution. I don't have the test facilities or time or spare device to do that. Buying a new one is so much cheaper.

That Krups board looks like it is from the disco era, back when the Bee Gees were singing Staying Alive.

I had to go back and look at the image after that comment

Date code on the IC?

Sorry, IC in post #19.

I still have over 10,000 surplus of the brightest 5mm LEDs in sealed bags with ESD protection builtin when I used to distribute custom LEDs for 1 client in NZ.

In the 90's I managed a quick turn SMT manual assy for RF boards with 6805's and ceramic hybrids under DIY tinned brass shields onto FPC boards. There were designed for retrofit (auto-meter-read) AMR in mechanical AC power meters with 928 MHz wireless custom radios. A girl could assemble 10 prototypes in 1 day easily with 3 PCB per assy using 603/805's.

Hi,

Ive been having these for so many years and i need to get rid of them

7$ each for big ones


pm me for more details

The ICM7225IPL is obsolete, and Digi-Key sells the ICM7217BIPI for $7. Akein Lithmal's price is reasonable,

Why do you think ICs stored in a little plastic box on the porch of a house in Sri Lanka with no handling history or promise of tech support, storage history and no chain of custody documentation should be priced the same as ICs from Digikey?

Presumably he will be buying them himself?

Or,

hello everybody !! im a newbie - a hobbyist, , with a very very minimal /basic knowledge of Electronix - but - with a Profound love for electronix, this is /or will be my first post , pardon me if say something wrong or post something in the wrong place ..

To the OP... i would have bought one of them IC's from you , but unfortunately , wont ...and cant ....because im first hunting for the circuit i need, and only then , will go for the components. The one I refer to is the IN4017 with the 16pins !!
Also when i last checked with my buddy, chatGPT - what i need is a M4017 and the M4011 - made by OKI -Japan, which is Obsolete and no more , chatGPT told me to go for an alternative, namely CD4017 and CD4011 ( easily available) - but still i cant go for that - until i find my circuit.

But i was Happy for a few seconds when i saw that ic image in the bunch - -sadly, cant buy , for now at least.

I wish you all best in your Sale !!

If, as ZipZapOuch stated, vibrations loosen the SMT components on their PCBs, then that is reason for a product recall.
