How Do I? Beginner's Paradise. / Re: IC Insertion
« on: April 05, 2015, 05:08:38 PM »
Last I checked (Tuesday), we still had one Radioshack store open.
I gotta go into town on Friday.
I guess I should check, if they are still there, for some extra tips for that then.

Love your sig :)
Layout design is probably my favorite part of pedal building.

I got one of these:
On the right side obviously.
It was only about $5 I think.
If you hurry, you might still be able to get one.

Amazon has a selection:

Off topic, but on the left is a cap tester I built from a kit:

Does the IC solder pump works well?

I also have built one of those capacitance meter a while ago, works quite well, much usefull with tropical caps...
Do you mean this thing? :

Yeah, that works quite well.
Word of caution though...
Leave it unplugged.
When you need to use it...
Plug it in.
Let it heat up.
Use it,
Unplug it.
If you leave it plugged in for hours at a time, the tip deteriorates rather quickly.
Not a bad tool for only about $10.
IMO, works much better than those plunger types.


Off topic, but here is my DIY enclosure for the cap tester.
Just applied some heat with a heat gun to a piece of lexan (Plexiglass sucks). Kinda overdid it a bit with the heat gun though.
I also really need to get around to raising that socket up a little higher.

I made the enclosure large enough so that I can fit a 9 volt battery underneath it too.

Still exploring the site and found this thread so my sig is updated.

My affiliation with Smallbear is doing layouts for their DIY section.
I get a flat "fee" (in parts) so I can continue to build my own stuff.
He can sell 1 part related to my work or 1,000 parts, my benefits stay the same.
Not complaining, just making it known that if I mention Smallbear as a place to get X part, I don't get any "kickbacks"  :P
I'm quite satisfied with our arrangement.
But thats kind of on hold ATM as I have been too damn busy doing stuff around here for my mom, and after that I'm usually too damn tired to do anything but veg in front of the TV and hang around on forums and otherwise waste my time looking at cat gifs and crap.

Dalton Jones Electronics is me.
Unfortunately that one is on hold as well.
At least until I can get the funds together to actually do some proper builds :(

You can get just about everything on your list at Tayda, actually. They only sell one size of the passives (0805), but they have lots of values and also transistors, op amps, and regulators. They don't have diodes for some reason.

Mouser and Newark have everything, but shopping at those places takes a little bit of practice.

Yeah, mouser takes a little getting used to.
Can be a bit confusing if you don't know exactly what you are looking for.
Forgot about Tayda.

And just as a word of caution, an FYI or whatever, I ordered some 1n34a's from Tayda a few years ago that I suspect are fakes.
The voltage drop on them was around .6x.
And the package was different than what I've normally seen for 1n34a's. It looked more like a 1n914 as far as the package goes.
But other than that, I've been satisfied with what I have bought from them.

MMBT (MMBT5088, MMBT3906) prefix for BJT (Some prefixes may be different though. I selected for Fairchild Semiconductor for the manufacturer in this case. Other manufacturers may use different prefixes).

Here are some diodes, as an example, which lists an SMD version of a 1N914 :

Basically what you can do is go to, search for say voltage regulator, Diode, Capacitors, etc., when the new page comes up, there are several other search parameters you can narrow the search with.
Use the "Mounting Style" list to choose SMD/SMT (or whatever form factors suits your needs).

Mine is in my sig.
But in case I change my sig...
My birth certificate says Robert, but I go by Rob.

Welcome to the forum!  I you are interested in eagle, check out all the great info here, including a great parts library and all of JMKs video tutorials (these are a must watch and will get you 90% there overnight):

Thanks all you great guys/gals/turtles/cats/etc.
And thanks for the kind words Brian.

I checked out one of JMK's Eagle videos last night.
Quite informative.
He presents the info quite well.

BTW, here is one of the folders on my system:
Size: 3.60 GB (3,868,232,085 bytes)
Size On Disk: 3.60 GB (3,871,449,088 bytes)
1,243 Files, 52 Folders

Videos, PDF, HTML formats.
Although some of the videos are dupes, MP4 converted to AVI (or the other way around).
Haven't had much time, especially lately, to watch or read most of them yet though.
I hope to get to it soon though.
And it looks like I have a few more videos to add/watch/study courtesy of JMK.

I've of course got the Madbean library, just grabbed the 2014 library last night (Boy was I out of date :)  ), as well as the Gaussmarkov library.
And I've also got mmoltertx I can grill for info now and then.
He's pretty damn good with Eagle as far as I can tell.
Pretty smart guy.

And I wish I were a rocket scientist.
All that stuff fascinates me.
I didn't design any of it, I just put it together.

JPL was a REALLY, REALLY cool place to work.
I've also built radar detectors, automated sprinkler systems, AV systems, thermal printers, and all sorts of stuff I can't remember.
It was the 80's when I got started with electronics and I was living in the San Fernando Valley.
There were Zillions of electronics manufacturers down there.
If you could solder, there were jobs to be had on damn near every corner.
Hell, at one time I was working day shift at one place (7:00am - 3:30pm), swing shift at another (5:30pm - 2:00am), and 12 hour shifts on Saturdays and Sundays at another place.

Thanks guys.
In between messing with LTSpice, Eagle, and looking at cat gifs, I've been browsing the forum tonight.
Some pretty interesting stuff around here.
I think I'm gonna like it here.

I haven't had a chance to do much building or designing lately due to several major projects around the house/property that's been kicking my ass.
Been doing some stuff for Smallbear, but had to put that on hold until I get some of these projects around here taken care of.
There is some light at the end of the tunnel though and hopefully, I should be able to get back to doing what I enjoy doing soon.

Crap, its almost 6am, I should get some sleep.

I could have sworn I joined this forum years ago.
But I guess not.
Anyway, I'm sure at least a few of you DIY'ers have seen me around the other DIY forums.

I live in a little place in the middle of nowhere called Stagecoach, Nevada.
Its about 30 miles east of Carson City, Nevada.
And about 60 miles or so from BEAUTIFUL Lake Tahoe.

About me?
Well, I'm gonna take the lazy route there and insert a post I made on TGP when someone questioned my qualifications when I degooped a pedal "made" by a suspicious "builder":
Ok, brief history lesson for you, not that it matters or is relevant.
BTW, how is it relevant as far as de-gooping a PCB goes?
I didn't realize that I needed to be an EE to de-goop a board.

1981, I took a 2 month course at a local occupational center for electronic assembly. That class was taught by a retired NASA technician.
Over the years I worked for numerous companies as either an electronic assembler or technician (learned the tech end of things on the job and some classes at Pierce Junior college and CSUN (California State University Northridge).
I also read books and did the hobbyist thing as well.
Over the years I worked primarily for military contractors and sub-contractors doing PCB assembly, cable/wire harness assembly, Operated and maintained wave solder equipment.
I also worked at NASA/JPL as a technician doing flight system PCB assembly, Ground Support Cable Assembly, Polymerics technician (Working with epoxies).
During my time as a Polymerics Technician I also de-gooped PCB's.
Yes, I de-gooped PCB's for NASA/The US Government and those PCB's probably cost more than the house you live in.
I worked on the Galileo Space probe, early Mars rover, several space shuttle sub-assemblies and other stuff I'm not allowed to talk about, EVER.

That takes us up to about 1988 and I think that's babbling enough for now.

Did I pass the audition?

To continue on...
I built my first pedal from a kit I got at Radioshack around 1981.
It was a reverb pedal.
Of course, me being the tinkerer I am and suffering from what RG Keen calls "BUMS" (Blind Urge To Modify Syndrome), I immediately started to modify it.
Even though I had no clue what I was doing.

Most of the stuff I build is on PCB's which I etch myself.
I occasionally do builds on perfboard or turret board.
Heres a turret board build I did a few years ago:

I've been using DIYLC for quite awhile.
And I've been playing around with and learning Eagle off an on for a little while, but still have LOTS to learn about it.
Madbean's library is a wonderful addition to the Eagle library.

I like Rush. Alex Lifeson is my guitar god.
And Southern Rock.

And I noticed that there are a few people from Fresno on here.
I saw my 2nd ever concert in Fresno (my first concert was Johnny Cash at the Los Angeles Forum in 1970).
The Outlaws opening for Boston (The Outlaws made Boston look like a bar band with stage fright) in 1976 or 1977.
I also went to high school in Mariposa.
