Further to post #503

You can of course add other SMD components to machine pin headers.

Hi,

If I have to solder like this, using a protoboard, I have an el-cheepo board that I use all the time.
The heat from the pins can cause the clips loose their spring properties if you are soldering solder pads, that take a bit longer to solder, on a PCB.
Also a worn board is easier to insert and remove your work.

Hi Tom.

I use this old breadboard for soldering.
Not sure where I got the board, just realized it only has one power rail on each side.

I just ordered some new machine pin headers.
Looks like they now have a bit of a bulb on the pin side.

Not sure if I like the little bulb, means the pin will only have the solder joint as support, the other type without the bulb will sit right down on the PCB.
If you use them a single test points the non bulb will be better to keep the pin vertical during soldering and support from the PCB.

They would be okay as pins into protoboard.

Needs a "suck and see" to find if they are good.
It will be interesting how they sit when you solder them.

It looks just like the protoboards I bought from Radio Shack in the '80s. They still work.

Stacking jars, mentioned earlier, can be used to keep your hook up wires organized.

Several places on the internet to get jars.

That is a great idea.
I purchased 10 of these boards to do something similar.

You Must corrected this error before you plug it onto an Arduino.[/color][/b]

'On that board' they connected 0V to +5V, you need to correct this as shown.

Always check for Vcc to GND shorts with ohmmeter.

I recently had a problem with these falling out of their sockets too easily.
Certainly worse than the square ones.

Sometimes, drilling plastic can be difficult.
An: engraving/end mill/spoon/D bit can make this task easy and safe.
Chuck your bit in an electric drill or cordless screw driver.
At slow speed, advance the bit into the plastic.
These bits cut clock wise. (looking from the drill to the hole)
The single fluted bit cuts thin shavings as it advances.
Since the bits are tapered, you can drill smaller holes than the bit diameter, if you drill partly through the plastic.
However, the hole will be tapered.
These bits are made of carbide steel, avoid forcing the bit as this may result in the bit breaking.
And, these bits are SHARP!

Different bit degees available, 10,15,20 and 30°.
1/8" bits are ~$1.00 each.
Lots of suppliers on eBay:

I have used caarbide drills but find they break too easily even when used in a drill press.
The dremel drill press does not seem to be rigid enough and there is a fair amount of runout on my dremel as well.

Can you use those by hand ?
