Yes.
Stood to attention.
Just had to bump my favorite thread back to the top.
But the only tip I have is Don't eat the yellow snow- Zappa

+1 ... Watch out where the huskies go, and don't you eat that yellow snow
Ciao, Ale.
So I might have to convert a little bit to the Bent Tip cult religion team...look, it just works well, OK?
I bought a soldering kit for my little sister to assemble, and she had a much easier time using the bent tip than either a chisel or knife tip. I still haven't used it myself (haven't had to solder anything recently), but there's at least some good newbie potential in it.
What kit? A theremin, and I didn't tell her what it was. 
I really wish I had thought to record her reaction when she reached out to touch it for the first time after I plugged in the battery.

Hi Larry,I started THIS on http://ArduinoInfo.Info
May I add yours??
Anyone else??
Terry - I have seen a wiki site you have started and read an excellent article on there about controlling AC power with power FET's. Would you mind if I dropped you an email?

I recently upgraded an iPad app that I use everyday (~$10.00 for the upgrade).
I use ‘PDF Expert’ for all my PDF reference materials: data sheets, books, articles, equipment manuals etc.
PDFs, like the 650 page Amtel328 data sheet, can be: searched, bookmarked, annotated, edited and sent to other apps or printers.
The new upgrade allows you to:
- edit existing text - font/color/content/size/position
- add/move/resize images
- redact text
- link text to other page or WEB references.
Of course, you can still annotate: draw/highlight/add comments/add text/add signatures/add and delete sheets/add stamps.
I always sync my PDF documents to offsite storage for a backup.
I got rid of 300 pounds of data books from my shelves.
Can’t live without it!
(I have no affiliation to PDF Expert)
Example, before and after:
I just received some 1284 Logger and MegaDIP boards from Crossroads.
If you ever need more I/O and more hardware serial ports these boards are for you.
Here is a MegaDIP mounted on a second story breadboard assembly.
Thanks Bob.

Looks like the beginnings of a serious project. What are you building with it?
I did not have an Arduino Mega2560 yet, wanted to get more I/O for a test jig I making.
86 I/O lines, (16 analog inputs, 4 hardware serial, 74 digital I/O)
All in a dip package.
Also, the 1284 Logger not shown here, has two hardware serial ports and a micro SD card for logging. Placing it in a serial data analyzer I am working on.
What you see here is a hardware staging breadboard discussed earlier on this thread.

Every now and then you might want to protect PCB components with a piece of clear plastic.
The clear plastic allows LEDs, LCDs, etc. to show through and it protects things from accidentally shorting.
Save those old DVD/CD cases and use them to do the job.
These cases are about .05 inches thick and are easily cut to size.
I love Irwin clamps.
My preference is for CARVER clamps but almost impossible to find on the shelf in US and Canada.
They make irwin clamps and similar look like beginners clamps. LOL
Per image #3 in post 331.
Made some of these boards a few weeks back.
They greatly speed up wiring and in checking out that code with LEDs and switches.
Just plug the assembly in the female headers.
6 LEDs and 6 PB switches.
Having the PCB on a 18" umbilical cord makes things quite convenient.
Edit:
See post #392 for the sample sketch to go with this circuit.

Anyone know of a cheap source of flux in the UK that i can use with a dropper or nail file brush please ?
Pens are rather expensive , all i want is the flux.
Make your breadboard jumpers well ahead of time.
A good source for wires is old computer and Telco cables.
For breadboards, I recommend Telco #22 and #24 AWG wires, but prefer #24.
Both stranded and solid #24 AWG is available in the Telco color code scheme.
My preference is to use #24 AWG ‘stranded wire’ for jumpers but you must do some work to make them usable.
The Telco coloring has five tracer group colors: White, Red, Black, Yellow and Violet.
Each tracer group, has five color pairs: Blue, Orange, Green, White and Slate.
One complete bundle contains 25 pairs or 50 wires.
50 wire colors give a well diversified color layout for your breadboard projects.
I like the version where the insulation is one solid color (eg: White) with a quick splash of color (eg: Blue)
W/BE is the TIP wire and BE/W is the RING wire.
A big part in wire preparation is the tinning of the stranded wire.
A solder pot is ideal but a soldering iron is adequate; using flux is advised.
I really liked the trick with the CD case plastic protection.
On a similar note, how would you insulate a part of a PCB track that has been left bare (no mask) intentionally in order to enhance the ampacity with additional solder + copper later. For example see the following picture of a PCB I made:
The top tracks are shown bare, exposed . Reason is I intend to add additional layers of solder and copper to increase their current carrying capacity as they will be carrying upto 10A at 240V AC (relay footprint below).
It would be nice to add some kind of insulation later on. Is their any sort of insulating spray / lacquer ?
First off, solder mask is designed for masking solder flow during the soldering process.
It offers some insulation quality but is not designed for such.
In your example consider this using slippery tape.
The glue it uses is outstanding.

Kapton tape might be an option.
A third option is epoxy glue or clear silicone glue, I have used both as electrical insulation.

How about hot glue, from glue sticks ?
