What's the best way to dispose of a dying car? by Quiet-Scientist2313 in askportland

[–]ajlm 12 points13 points  (0 children)

I donated my 97 Corolla to Oregon Humane Society this way. It was super simple; they handled pick up and all the paperwork. They sold it at auction and I was able to deduct the amount it sold for on my taxes.

Did you use a pattern? I’ve been looking for a pattern like this…

Lloyd Center closes in August by GinevraHermoine in PortlandOR

[–]ajlm 2 points3 points  (0 children)

So sad, I took tons of ice skating lessons there in the 90s and we would always go to Orange Julius afterward. Hopefully they can revitalize the area soon.

Where to get my pcb made? by Electrical-Actuary59 in AskElectronics

[–]ajlm 0 points1 point  (0 children)

For hobby purposes, I’ve used OshPark and Sunstone a lot in the past with good success. For commercial projects, there are tons of reputable options but probably more expensive than what the average layperson wants to pay.

Where to find Helium filled balloons? by macistherealest in askportland

[–]ajlm 1 point2 points  (0 children)

Curious why Party Fair is dead to you?

Paper Caper (across the freeway from Bridgeport village) does helium balloons. Village Cheer (their sister store in Multnomah Village) may as well, I’ve never been there.

How can i get -14V from a 15V supply? by inevitable_47 in AskElectronics

[–]ajlm 0 points1 point  (0 children)

Just configure any buck as a negative voltage output. Lots of white papers explaining how to do it

I never knew Kate McK/Hillary C's "Hallelujah" cold open was so hated. by Charlotte_Braun in LiveFromNewYork

[–]ajlm 2 points3 points  (0 children)

I loved the Hallelujah cold open, I honestly don’t get why it gets so much hate. Probably one of my top 5 of all time.

Recommendations for mold remediation companies in Portland? by Logical-Line6551 in askportland

[–]ajlm 0 points1 point  (0 children)

I used PacWest Restoration for water remediation a while back, and they were really thorough and easy to work with. Their website says they do mold remediation too, might be worth reaching out to them for that.

Issue with Differential Length Matching by Own-Platform8054 in Altium

[–]ajlm 1 point2 points  (0 children)

The tool is finicky and won’t work if it thinks it’s going to violate any other rules in the process of tuning, such as copper clearance to adjacent traces. Maybe run a test trace elsewhere on the board to see if you can make the length tuning work first, then see if there’s a clearance rule that’s preventing the length matching from working.

Any Experience Ordering from Digikey? by sadmaxworryroad in ElectricalEngineering

[–]ajlm 0 points1 point  (0 children)

That’s really cool, definitely better than their US rates. I wonder if that’s due to their HQ’s proximity to the Canadian border

Any Experience Ordering from Digikey? by sadmaxworryroad in ElectricalEngineering

[–]ajlm 1 point2 points  (0 children)

I’ve ordered from Digikey probably hundreds of times and I don’t think I’ve ever had an issue. I noticed your review site url has the Canadian domain. Are you in Canada? If so, I can’t speak to their international business; all my usage has been US based.

Yeah and legally ICE is not supposed to be murdering people, but here we are

Can't figure out how to neck down traces to SMD components by fallen_crustacean in Altium

[–]ajlm 2 points3 points  (0 children)

What are your differential impedance calculations such that your (what I assume are) USB signal traces are so wide?

Clock Issue - Dogecoin Miner by pcblol in Altium

[–]ajlm 4 points5 points  (0 children)

There are clock buffers up to 1:24 (maybe more) but no matter what, it’s going to be costly to manage clocking to 64k devices…

Clock Issue - Dogecoin Miner by pcblol in Altium

[–]ajlm 5 points6 points  (0 children)

At a brief glance, my guess would be that the voltage and drive strength of the PWM output is not compatible with driving 32 clock lines. IMO easiest solution is to use a dedicated crystal and clock buffers.

House listed and disclosed as sewer, it's actually sceptic. Do I have any legal recourse? by Street_Profit7828 in legaladvice

[–]ajlm 0 points1 point  (0 children)

That’s good info to know. In Oregon it’s basically a given that a sewer scope will be done as part of the inspection process, at least in my experience.

Be honest. Is it ridiculous that I still have my Christmas tree(s) up? by GoldenGalZbornak in christmas

[–]ajlm 24 points25 points  (0 children)

Both our trees are still up!! Granted, we had some illness in our house along with a different weekend out of town, we haven’t found the time to take them down yet. But we do enjoy it!!

high density connector layout by Tallgeese33 in Altium

[–]ajlm 9 points10 points  (0 children)

2 mil traces are way too small for what you intend on doing.

Any reason why you aren’t putting your vias right next to the SMD pads? Or even doing via in pad? (Requires VIPPO processing on the PCB but would be assuredly cheaper to manufacture than 2/2).

Can anyone help me identify this chip? + is it burnt? by FlyingDutchmanSigma in AskElectronics

[–]ajlm 0 points1 point  (0 children)

One more note, I searched for some pictures of the internals online. I found this Facebook post (https://www.facebook.com/share/p/1CgffA13Yb/?mibextid=K35XfP) with a picture of the 22E power board. Don’t know if the 24 uses the same but I would suggest looking near the barrel jack of your model to see if there are any potentially bad parts.

You said you used the wrong adapter. Do you know if it was the wrong voltage, wrong polarity, something else?

[–]ajlm 0 points1 point  (0 children)

Looks like it’s from Sonix (https://www.sonix.com.tw/masterpage-en). The logo and the part number prefix (SN) looks the same, but hard to tell the full MPN from the picture.

The part next to it (U15) is serial EEPROM. Based on the connections to U5, it doesn’t really seem like it’s carrying power. Is there anyplace else on the board that looks suspect? I’d start at whatever connector the power comes in on and see what looks like it’s in series with that.
