Has anyone on here played with pummer circuits?

The modern online retail economy sucks!

I need one 74AC240 chip for this. I could order a pack of 10 of them from Amazon (yuck) for $12.25 + $6.99 shipping, a single one from ebay for $2.50 + $12.50 shipping, a pack of 10 of them from ebay for $4.99 + $5.20 shipping, or one for $2 + $10 shipping from Mouser.

UGH

I would pay $5 for one if i could get it in a store right now in person, using my own body to pick it up and pay for it

@MLE_online

Now you're making me nostalgic for the days of electronics shops or stock rooms

[emma@orbital.horse]

@MLE_online losing the local electronics supply stores like we used to have in Silly Valley sucks.

[mle_online@social.afront.org]

@alienghic Fry's sucked and Radio Shack sucked while I was old enough to be cognizant of them and visit them, but at least I could go Buy a Thing

[justinto@mas.to]

@MLE_online there's a Mouser warehouse in my city and a Mouser Customer Service office a 10 minute walk from my work, and none of it gets the parts in my hands faster or cheaper

[mle_online@social.afront.org]

@justinto that sucks. There's a McMaster Carr in my area and I can drive over there and pick things up at the counter the same day I placed the order, and without shipping and handling charges

[alienghic@timeloop.cafe]

@MLE_online At least they had decent selection even of the floor models of things were all slowly being destroyed by the customers.

[stormgren@obsidianmoon.com]

@MLE_online Yeah, it's why my home hackerspace has a whole wall of honor-system components for exactly this reason. Can't get a lot of things quickly otherwise.

Had never heard of the pummer circuit before, looks like fun to have around.

[mle_online@social.afront.org]

@Stormgren how would you even know of all the components you could possibly need? I have a bunch of capacitors and resistors here, but the list of components is endless. I had never even heard of this chip before now

[acesabe@infosec.exchange]

@MLE_online
Presuming the days of Radio Shack et al are long gone (not sure how they could carry the range of possible stock anyway these days)...
AliExpress, is that usable from the US? I've ordered things that have made if from China to W Europe in 6 days....they also have "local" supply options but I'm dubious...

[ruenahcmohr@infosec.exchange]

@MLE_online ...or ask rue to donate ya one for the project and stuff it in a snail mail envelope for free....

[ai6yr@m.ai6yr.org]

@MLE_online @Stormgren I might have one and can send it to you for free, lemme look

[ruenahcmohr@infosec.exchange]

@MLE_online @Stormgren it's true

[justinto@mas.to]

@MLE_online oh, I could use fast access to McMaster Carr parts! The cost of shipping constantly stops me from building things and I always forget a part or two to finish the project. In my last job I had access to almost any component that I needed and it spoiled me to the point where I don't build much anymore. I hope a friend finds you a chip in their supplies

[stormgren@obsidianmoon.com]

@MLE_online I mean, it's not going to be an exact science, but resistors, caps, and whatnot come in assortments so that's an easy setup. Cruft extra parts and donations tend to accumulate so that also helps, and sometimes you need to just do a mouser order and group brainstorm stuff that people said "wow, I wish we'd had a $foo sitting around, could have used one the other day to fix a thing" and stock up. Then curate every so often.

I have a pile of stuff personally that's accumulated over the years, so it's hard for me to judge, but any time I order parts, I usually get a couple of extra if it's not too much, ICs don't tend to take up a lot of room.

(The 74AC240 isn't an uncommon logic chip, or at least it didn't used to be)

[stormgren@obsidianmoon.com]

@ai6yr @MLE_online I was just doing the same thing here, I would swear I've got some around here I could part with.

[mle_online@social.afront.org]

@acesabe yea, i order from aliexpress, and the prices are good, but im not going to mail order a single chip from china

[mle_online@social.afront.org]

@RueNahcMohr you always say canadian mail is extremely slow and unreliable though!

[mle_online@social.afront.org]

@ai6yr @Stormgren if you do and can, that would be amazing
