I tried @DAJE ...but I think we can call it...I'll float another bottle your way ;)

I have been wondering about that. It still could show up, 6 weeks is about when I start worrying.

I ordered my Pinecil from China on August 2. They shipped it on August 8. The plane entered the port one city away on August 21. No more updates. I keep checking the Mars rover Twitter account for any sightings.
 
I feel ya guys, I’ve had 2orders sent via truck that could have been dropped out the arse end of plane between it’s stops going over my home and another thing take 3 days to travel the whole state when it’s a max 40 minutes in shite traffic on1 single highway to the factory/main office 🤦‍♂️

I saw Boris last night, and they had like no merch…the shipment was delayed. I never thought about merch logistics, but the state of shipping has to be a big issue.

Reminds me of ordering from the Sears & Roebuck catalog. 🕰️

Ok, so this how long I've been messing around with DIY guitars (and also dates me....HAH). My first guitar build, I had to order all the parts from a Warmoth paper catalog and a StewMac paper catalog. I still have and play that guitar, it's actually old enough to be "vintage" I think :p. It will be featured in an upcoming (hopefully sometime this week) Shut Up and Play Yer Guitar episode.

When your morning starts with this…

…I dunno, but my morning DID and it sucked (yeah yeah punny ). To boot, it was used to remove a leaf-pin socket, which I only use when practical. This was for an ATTINY so yeah makes sense….only I get to the last pin and there’s no pin? -Let me interject that I am long overdue for a lens prescription update for my astigmatism but I’m not playing that card…I just wasn’t paying attention. 🤓 🌴

Soldered seven pins before noticing there was no eighth !

I was looking for what I consider a necessity, but haven’t read much about here, an IC tester. One of the reasons I build these boxes of love, is to learn this stuff. I appreciate the ability to test each component being used on a build. I don’t test resistors unless biasing, but I could…and that’s kinda my point I guess, but hey…that’s my groove.

I bought an Amazon special. It performs good egg /bad egg testing on a variety of ICs. I thought of bridging a couple of pins to see how it responded, but I’d rather put it through the paces with a suspected fake chip, as well as a few fried, zapped, and otherwise abused devices.

That said, I’ve decided to purposely disable a few in the name of science….okay and because it’s an excuse to blow stuff up. I’ll derail the opamps, decompress the compressors, make logic chips illogical, and so on!

Here is the menu of AMP "types" it tests. A TL072 or RC4558 will test as TL082...OK or FAULT.

LM324
LM741
TL082
TL084
NE555
LM2904
LM2902
LM393
LM339
LM358
LM324
LM741
It also has menus for TR, ZD, OTHER (ULN2803), LIGHT, 45/145, HEF40, CD40, 74LS, 74HC...so lotsa stuff. I'll report back...maybe with a video of a frying IC 🤣

I did try shorting and lifting a few pins....it was at least smart enough to catch that. 🤷‍♂️
 
So what exactly is it testing? Not sure yet, but what could we test building small circuits around the DUT? I'm going to use a LM324 to go build some of the possible tests including;

Ios Input offset current
Uos Input offset voltage
Aud Open-loop differential factor
CMRR Common-mode rejection ratio
Uicm Common-mode input voltage range

Each requires a bit of math but this is electronics, not .....hmm, welp there's math in everything.

To the breadboard!

PS: I may get that fried IC as a result of all that probing... 🤣

This thing says is also tests transistors. Have you tried that? Does it give you any more info than the T7? or T1?
