Re: Insurance is Expensive Journal

I have to say it is really interesting listening to you think out loud. You have a complex brain. A lot of voices in there eh? :D I’ve been asking myself a lot of the same questions. After the fact though. I wasn’t smart enough to ask this stuff when I was in the middle of it. In my endgame I’m seei...

Re: DIY software development and/or electronics?

Uh, this was stupid easy @SavingWithBabies. You can knock this together in an hour. It only cost pennies in pins and pennies of filament. Not sure how useful a pin test fixture is in general. Today we can build a lot of self test into our hardware for pennies. If you need test I/o there’s in circuit...

Re: DIY software development and/or electronics?

Wow! Now that is cheap. Basically use what everyone already has. They make great LCR meters too if you can find SW.

Got me thinking of tablet and phone apps. There are a bunch there too.

You can do a lot with sound card bandwidth. It beats flying blind.

So many options.

Re: DIY software development and/or electronics?

Ok! Yes you can make a pogo pin test fixture with a 3D printer! @SavingWithBabies - you have ESP by the way. Here is my first cut mocked up on the bench. I 3D printed the base for holding the PCB and the overhead pin probe for flashing. The base has ball tip contacts so the board can slip into the s...

Re: DIY software development and/or electronics?

@Sclass Have you thought about 3d printing a test adapter with pogo pins? Probably totally unnecessary but if you have a test a bunch of them and want to tinker anyway, might be fun. Funny you ask. I’ve been working on one right now. I’ve 3D printed the base that uses pogo pins for power, ground, s...

Re: DIY software development and/or electronics?

I simulated a circuit on http://www.partsim.com. It’s a free online SPICE simulator. A lot easier than breadboarding and measuring with a meter and scope. I’ve tinkered with spice in its various forms over the last thirty years. This is basically the same thing but it’s a lot easier to use. Drag and...

Re: Fixit Log

Reminds me of a great fix. To make espresso reliably I use a burr grinder. I cheat and use an electric pump machine by Krups, but it still requires a very consistent grain sorting that I found I can only achieve with a burr grinder. So I wore out a burr grinder from a garage sale. It was unfixable.....

Re: basic electronic toolkit? preferrably nontoxic?

I think there is lead free solder but I've never looked into it. There is. The whole ROHAS thing went down a decade ago. It was hell for engineers. It’s just effing wrong on so many levels. (Rant removed). http://www.sigcon.com/Pubs/news/10_01.htm Some things to note. Safe lead free is really expen...

Re: basic electronic toolkit? preferrably nontoxic?

@planting- SPICE is a great suggestion. My favorite and most easy to use version is the free LT SPICE. On a simpler more easier to approach level I’d try Tinkercad. Designed for kids. I’ve never used the circuit sim but it looks like a great learning tool. Check out some of the YouTube vids on Learn...

Re: On deleting journals, posts, and accounts

Oh wow. I was wondering what all the fuss was about. Once I looked back using the search tool I almost flipped over backwards. The forum looks like Swiss cheese! I get it. We talk about some touchy stuff here. People are scared AI or Real Intelligence will connect the dots. Reflecting I will say tha...

Re: basic electronic toolkit? preferrably nontoxic?

Not much to add to the above posts. That’s a great start. A soldering iron, meter, a pair of wire cutters, tape, shrink wrap and some wire. What the folks already said. Learn how to see electrons with a voltmeter. Get a Harbor Freight digital model for nearly free. Watch YouTube to learn how to use ...

Re: 39 & Looking to retire this year. Advice appreciated

My bad; I was thinking that was an annual amount. You'd want to take smaller amounts out every year rather than all at once so you're not pushed into a higher bracket. Actually that was what I meant when @unemployable replied with the high tax expense. I had the idiotic idea to take out the $350,00...

Re: 39 & Looking to retire this year. Advice appreciated

Yeah that is pretty cool stuff I had no idea something like 72t existed. I can imagine how this got into the tax code. It seems kind of self defeating.

I guess reading back the OP said right up front he was going to access his funds in this order.

Re: 39 & Looking to retire this year. Advice appreciated

So I’ve been playing around with the tax deferred account problem in my mind while swapping an alternator in my car this afternoon. Does it really make a difference if $1M is in a regular investment account and $3M is in IRAs? Let’s turn the problem upside down. What if $4M is in a regular investmen...

Re: DIY software development and/or electronics?

I designed some circuitry this week. Its for an adaptive hysteresis filter to capture zero crossings out of a noisy signal with widely varying input amplitude. Since it is a prototype I decided to mill it out on my CNC machine using isolation routing. This way I can see how it works before I commit ...

Re: Buying an e-reader

E ink was originally designed to be as contrasty as a paperback book. Theyve gotten better since the Gen 1 back in 2008. I thought e ink was the greatest product at the time. It seemed smart. I like my e ink kindle over paper books because the books are searchable. Also the 2000 books in my library ...
