Where did the stickies go?

[Pat Amaral]

I finally get a chance to go through the whole thing to record the important bits and what happens? Has anyone got a copy of the threads that have gone away? It would be an incredible help and will be much appreciated if I could get a copy of the file(s).

Thanks in advance,

I was wondering the same thing. There was some good resources that went into the bit bucket.

Yikes they both died.

Well I had a little tutorial in there on helping folks sort out the digikey search results. Once you understand what you're looking at you'll be disapointed with jamco's and radio shacks but that's no surprise. Search engines for electronic parts and the way the results display make it a lot easier to find a neat part.

I saved this section in word, I think I had to edit it after the initial writing so those edits are lost:

Help with sorting out a parts search at Digikey:

Your best bet is to look at the data sheets, some while be low power, others will have higher fanout capabilities (number of other logic gates it can drive which translates to higher power draw but also higher power for LEDs), others will be in different cases, like the small outline packages or SOP. I think there’s a pic or two of an SOC style chip somewhere. . .
Well there's a blurry one in the pictures from the buildday:

also if you're looking at digikey and at the small outline parts, there are two ways to get these, on a spool of a 1000 plus or by cut tape. The parts are kept on/in a piece of 'tape' that machines can peel open and pick the part out of. Since we don't want a thousand at a time they offer to cut off a length of the 'tape' holding the number of parts we order, thus cut tape.

You're looking for the CMOS version so when you read the spec sheet it should say the working voltage is something like +3volts to 15 or 16 volts. The chip will continue to work through a wide rang of battery voltages always nice to get a chip that can handle a wide range.

For example I did a search at digikey for CD4060 and clicked on the "Counters/Multipliers/Dividers(6 items)" link found:
Looking through the 6 items we see:

The first item is a 'regular' chip, the package type is 16 pin DIP (Dual Inline Package) It will have 8 pins on each side of a standard plastic or ceramic chip, if you have a 555 timer chip, its a 8 pin DIP with four pins on each side, two of these end to end will be the same size/foot print as this item. They are shipped in a 'tube' a plastic length of tubing that's shaped to hold the plastic housing and protect the legs (so the end profile of the tube looks like the outline of the end profile of a chip)

The next item is a 16-SOIC, shipped in bulk. These are the Small Outline ICs and appear to chipped in static bags or an even smaller 'tube' (as opposed to a length of cut type). These chips are nice when you really need to slim down the circuit board, they are surface mount components and you will need a fine type soldering iron to work with them, they also won't like a lot of heat so you need a good iron or small pen iron to make the final connection to them. I super glue the chip down to the protoboard and then solder little wires to the pins or other surface mount components as needed.

The next two items are non stock but lets look at their package type, TSSOP, in spool or cut tape. Well if you thought SOIC's where small these are even smaller.
The TSSOP by the data sheets is 4.5 by 5.10 mill inches where the SOIC are 5.6 by 5.10. If you can solder and work with TSSOP's without making a circuit board Kudos to you. It is possible for a home brew guy to attach chips with fine solder pins, you use solder paste (comes in a syringe) and a heat gun but this is best down with a finished circuit board, here's an mp3 decoder thingy a guy at work made using Eagle schematic/circuit capture program:
http://www.kc6sye.com/8_6_03.html
I built one for him, theres a small chip with a great many pins as-well-as a flash chip, that has many small pins. I did it at work with our fine tip soldering iron and a stereo microscope. Good practice for when we had to fix a board for work.

The next item is another TSSOP but digi-key will load a reel with the amount you want, but we don't use reels, as described before this is a reel of parts captured in a piece of tape (not sticky tape its more like a bit of cellophane holding the parts in individual compartments chips are usually in anti static plastic, capacitors and resistors in paper. I can snap some pictures of the left over reels here at work, they look like plastic film reels).


.The final item is another 16 pin DIP, its different from the first item by its manufacturer. But also by its designation, lets look at the data sheets, found by clicking the item part number, and then again on the item part number on the next page (in the table), and then the Data sheet link on the next page. . .

The data sheet as most are, is in pdf format. . .
For the Fairchild part
The part is rated 3 to 15 volts operation, and can clock or blink at 8MHz with 10 volts power supply.
A table down on page 4 of this pdf tells us about the chip's power supplying capabilities depending on power supply voltage:
For 5 volt power supply, at +25 C she can source or sink 0.88 mA of power.

A review of the TI part from the first row of the table reveals:
Working voltages from -0.5 to 20!, but if you look over the table it only has specification entries for 5, 10, or 15 volts
We see that it lists it's current drive/source ability as 0.42 mA at 5 volt operation at +85 degrees. Yes there's a whole table of output depending on temperature and power supply voltage, and 3 volts isn't even listed. . .

These chips can't supply the 20 mA of power the small (2mm) White LEDs need, so the chip itself will be limiting the current/power delivered to the LED. But if you want to use one chip to drive more than one LED, best to setup a transistor booster. In that case a resistor in line with the LED (current limiting resistor) will be needed. This is pretty straight forward, you hook up the chip as you normally would. Accept you take each output of the chip you intend to use, and run it to the 'base' pin of say a 2n2222 transistor. . . ok well that’s another discussion altogether, maybe I can add it to the circuits page, or Zog can draw a diagram and we can add it to his LED section on the forums.

Hope this helps a little.

BTW the jameco part appears to be the TI chip, very similar data sheet (at first glance).



I looked up the parts for the 4060 circuit on digikey:
http://www.digikey.com/scripts/DkSearch ... =1424PH-ND

This is a basic 0.01 uF ceramic cap, it is not polarized so there's no putting it in backwards.

You can also get this in the surface mount version, which is not that hard to use really. I can snap a quick pick of a 0.1 uF surface mount used on the 555 timer circuit in that ring of LED's circuit. It is nice to reduce the height and foot print of the whole thing.

http://www.digikey.com/scripts/DkSearch ... -1523-1-ND

This is a 1206 Surface Mount Technology part, the numbering for SMT cap/resistor/LED block type components are the Length x Width so the part is 12mil x 6 mil or 0.12 inches x 0.06 inches + or - some variance listed in the spec sheet.

For the variable resistor here's what I could find on digikey;
This is the typical style you see in starter kits fairly cheep ~$0.50:
Adjustment made from the side (it mounts vertically)
http://www.digikey.com/scripts/DkSearch ... 62R504B-ND
Or adjustment made from the top (it mounts horizontally)
http://www.digikey.com/scripts/DkSearch ... 62R504B-ND
These are the discs with a slot in them see the 10MM Trimmer Pot. . .Series 262 mid page:
http://dkc3.digikey.com/PDF/T061/1280.pdf

Which one to use depends on how much room you have, horizontally takes more foot print but lets you make adjustments from the top of the circuit board (a hole over where the board is located in the model) or vertical mounting so a hole in the side of model lets you make adjustments. . .

This style I like, we have them in bins here at work. . .they are more expensive but won’t be damaged by water or dust (rinsing the model post sanding maybe?)

It’s a solid case with little screw head on top, the lower left hand of this pdf type is 3266W:

[en'til Zog]

Yeah, I was little surprised too. So is Ter-or who set up this whole thing. And OneZero....

I have most of the bits I put in and can build another thread with those, but they would go better as a sticky. There was a LOT of good data in both the Sparky & Zog threads - we need to try and rebuild those.


Good stuff on searching Digi-key, Sparky!

The notes I had on stripping fluorsecent tubes was from another post which I copied over. I couldn't find a word document that I might have saved a copy in. Those notes might be lost.

[LindaSmile]

They are gone.

A "sticky" thread shows up at the top of the list, but gets auto-pruned along with other threads. "Announcements" show up at the top, but do NOT get auto-pruned.

Looks like the Construction and Finishing forums are not flagged as auto-pruned, but the Lighting forum was. I turned it off. And later tonight, I'll change all of the "stickies" to "announcements" so we don't accidentally lose them again.

Go ahead and start a new thread for whatever you want "stickied".

Ah web code demisstified. Now we don't have to worry about grimlins in the server, it was operating as it had been instructed.

[en'til Zog]

"Auto-Pruned".

I thunk it was something like that.
