For the TSSOP and finer packages, if you don't have a toaster oven, or hot air gun, it will be difficult (but not impossible) to solder these by hand.

...or a hot plate, a syringe of solder paste, and a flux pen.

Yup... and a solder braid/wick to fix shorts.

i don't feel so bad about my own soldering now lol, how's that thing not shorting!

The late Jim Williams is a fan of this dead-bug style prototyping.

Get SOIC to DIP adapters.  Solder the SOIC chip to the adapter board and use that for your prototype.

... or just go straight to designing a PCB, use Oshpark or iTeedstudio for your prototype PCBs and feel free to use whatever chip you want.

For the TSSOP and finer packages, if you don't have a toaster oven, or hot air gun, it will be difficult (but not impossible) to solder these by hand.
19  Using Arduino / General Electronics / Re: What to do in vacations? on: June 08, 2013, 03:54:33 pm
I have completed my first year of engineering (Electrical and Electronics branch). And now I have vacations of about 2 months. I don't want to waste this time and I have to do something in electronics. I am really confused what to do. I have some basic knowledge about electronics. I have worked on arduino and AVR. I don't know much about SPICE (just some basics). Should I work on development board or just read books on electronics or attend some course like circuit designing etc etc. I really want advice from you experienced guys. Please help.
Thank you.

I'd suggest you BUILD A KIT.  Solder some parts together, make it work, troubleshoot. Just build something.... get your fingers burned, poke, cut. Develop some blisters. smiley

And when  I say *build*, I don't mean buying pre-fabricated modules or shields that you just snap together, or connect with cables. No... I really mean  insert the component into the board, solder it, etc. You need to learn the skill of soldering and working with the ACTUAL , REAL-WORLD components... and not just looking at it from a CAD representation or a Spice simulation. 

Build something REAL.  The experience and skills you'll gain will be invaluable.

Don't be like the others that graduate engineering school and have no diddling idea which end of a soldering iron to hold, or do such a crappy soldering job it's not even acceptable.

The 74HC595 exists in Eagle.

- 7 segments displays (C-391H)
Eagle has plenty of 7-seg displays in it's library. But it may not be the perfect match for your specific part on hand (dimension, pin layout, pin assignments)

C-391H??? Is that the actual part#? I can't find that part at Mouser.com or Digikey.
For "special" parts like this, the best thing to do is create your own library part.
There are lots of tutorials. It's very easy.

What do you mean by "Digital Oscilloscope" ?

Do you mean a 4-8 multi-channel Digital Storage Oscilloscope? Or an oscilloscope with an LCD flat screen?

I am using it for general stuff.

You can buy used pretty good Tektronix *Analog* scopes on eBay for a pretty good value.

Why don't you download the datasheet for your 7-segment display and your 74hcxxx chip and make your own part/library. 
Not every component you will pick  will be present in any CAD program you use.
23  Using Arduino / General Electronics / Re: CST-100 Connectors--how to connectorize on: June 05, 2013, 01:18:45 pm
These are small enough you can use a long needle pliers to crimp these.
For speed and dependability, a crimper is recommended.

<opinion>These look just like standard 0.1" pitch connectors. TE Connectivity seems more expensive than Molex (and Molex clones). I'd suggest finding an equivalent Molex connector. I've bought Molex (or Molex clone) crimpers for $40 or less. Can't remember where.</opinion>

no, other side
Ok, we're still neighbors. I'm in Brentwood.
25  Community / Bar Sport / Re: Yahoo advertizing on: June 02, 2013, 11:31:00 pm
Well I live in a small town outside of Nashville, we moved into this place in 2008 and our rate increases have been so nominal that its really hard to put a number on it without digging every single bill out and graphing it in excel, even then the line would be nearly flat.
so skyrocketing? not here

Hey, are you in Brentwood?

I have 3 teenage boys in the home,  one of them would take a 30 to 40 minute shower if given the chance,  this summer while he is on summer break from school, he has that chance at least 5 days a week,  

Are they still getting an allowance from you?  

Tell them if the monthly water bill exceeded the monthly budget amount, then all 3 boys will have their allowance deducted equally among them to cover the extra surcharge.  

On the other hand, a clean smelling kid is much better to be around with than a slobbering smelly teenager.

I'd say pick your battles wisely. smiley

My name is Frank Bates.

I live in a small town outside of Nashville, Tennessee with my wife Michelle and our 2 kids Jack and Samantha. And if you’re anything like me, you’re flat out sick and tired of watching helplessly as your power bills skyrocket even though you’re doing everything you can to conserve.

This is bullshit. TN has one of the lowest rates. 16th cheapest in the nation. Below the national average.

I looked at the cost of solar power a few years ago... with the low electric rates I'm paying, and the amount of sunlight I'll be receiving annually, and my monthly power usage, it's going to take about 16 years to recoup/break-even any solar investment (assuming nothing will breakdown, no maintenance costs, etc.) It's stupid. It's cheaper to pay the electric company than build your own solar array. 

29  Using Arduino / General Electronics / Re: [Eagle] Edit the info in Schematic Frames? on: May 24, 2013, 10:59:22 am
Iv just added the SparkFun Lib to eagle and have used the 'Schematic Frames' part, and was wondering how to change the information in it; Designed By, REV, and Date (iv worked out 'Title' changes to the files name when saved).

Find out which Library the part (i.e. frame) belongs to, open that Library, and edit the part (i.e. the frame). Save.
Now go back to your schematic, and select Update All so the changes you just did in the Library will be reflected on your schematic.

Fritzing is like a kindergarten kid drawing scribbles on paper and saying "hey look, look, look at my pretty drawing!"


What a f*cking mess.
