I'm using DIP chips. The main drivers for the timer and scores and quarter/period are MAX7219, which are in 24 pin DIP packages and the Darlington Arrays (2 ULN2803 and 1 TBD62783APG) are each 18 pin DIP packages. For the MCU I'm just using an Arduino dev board since they are cheap, ready built, and very easy to program. The LEDs just come in strips that get cut to length and each strip get a power connection and a ground, which both are controlled by the Darlington arrays, which are controlled by the MAX7219, which is controlled by the MCU. I have, however, drag soldered surface mount devices with fine pin-pitch leads, it's actually pretty easy to do so long as there's solder mask between the pads. I'll post pictures once I have it up and running. If it all works out I may layout a PCB in CAD and send it off to somewhere like Oshpark and get a run of a proper PCB made.
A few weeks ago I thought we were in Winterpeg (Winnipeg), Canada with the extreme lows but now we are moving into more of a Seattle/Vancouver like weather, which is mild and tons of rain. I think my state is trying to be Canadian, we even have Timmys!
I've never heard of those places that you mentioned.
Schilda is a fictious village where everything is done the wrong way.
One story is about a building a new town hall but the shield citizens forgot the windows in the town hall and inside it was pitch black. Therefore they tried to catch the light with buckets to light the rooms.
Unfortunately, at least in Germany, the search engine only offers German sources like the one below.

Isn't there a tech thread ? LOL You guys gotta speaka da english in here !
It's what happens when 2 nerds are the early birds to the cafe.
Also, electronics aren't really that scary when you break them down into the simplest parts and build up from there. It's like building a house. You know you will need windows and doors, so you draw up plans and make measurements then you find the windows and doors that meet those specs and then you install them in whichever way makes sense be it nails, screws or some sort of concrete anchor.
Anyways, I'm going to hang out here in the corner and continue to burp up the spicy chicken sandwich I ate for lunch .

Oh, by the way, the nerd coffee is the same as the coffee for all others.
DIPs are easy to solder and MAXIMS's are well known. I like sockets for DIP's. Easier to change killed chips. LOL Ten years ago I ordered DIP precision voltage chips for 2.048 V but got subminiature SMD's. $%§€

Very well, non nerd coffee, and a lot of it for you.
Plain English conversation depending on topic, hm, can be more difficult than modern tech speak. Tech speak is a broken English with terms, the world community has (forced) agreed on. LOL.

Aspirin and caffeine, please. I'm battling REACH and a review of DiffEq's.
*Nerd alert*
Why didn't I take DiffEq's in the engineering department? My prof in the math dept. was devoted to beating away anything as plebeian as an application that might have sullied his beautiful equations. As a stupid young undergrad, I didn't see the point in it. Now I kick myself almost every time I encounter a boundary value problem, which is a fairly frequent occurrence in QM, spectroscopy and optics, LOL. So, I'm doing an online course, to see if I can address some weaknesses.

I am sorry, Aspirin by Bayer is out but I can offer Dolormin Migräne in greater quantities. Coffee should be available for the next four weeks or so.
The combination of Dolormin and coffee may be counter productive.
#Nerd alert response#
Because it didn't matter if you had taken them in the engineering department. The math course was held by the same math Prof as for the Math students. LOL.
I have not done DiffEq for decades now and the good old books as well as the many exercises I have already donated to the archive.
What I do now does not require higher mathematics than solutions of systems of linear equations. Ok, a little bit computation of binary logarithm and if I want to make it difficult, transformation to polar coordinates.

There is still a pot of coffee for you. Fresh brewed.
LOL,
what I need now on my job of math should be of late Junior High may be first to second year of Senior High. Not really nerdy though you can make it look alike nerdy by technical terms.

Hi,
Just wondering if anyone has info on recipes for beef soup and frybread to feed 200-300 people at an outdoor powwow? My step-father passed and we would like to honor him with a feed but have never done this before. I would appreciate suggestions on recipes, ingredients, cooking times, equipment...
If you were forces to live on a small Iceland, big enough to do a powwow dance, alone, what would you bring with you?
There are off course fresh water and enough fruits to survive on your Iceland.
And it's hot enough to not fresh at night.
BUT no electricity, so sorry, you would...
PowWows.com is excited to open another new feature of the site!
You now can take quizes and compete against each other in trivia contests. The categories will range from sports, music, movies, to history, and Pow Wows.
There is only 1 quiz currenlty, but try your luck...
