Most of my sandpaper is for power tools and such so the longboard isn't too much use to me.

Even the stuff I do buy tends to be via China as they make most of the brand names too so I would rather not waste money just for it to have a middlemans name on it anymore.

As for your pricing maybe you could stock up at these prices

ballscrewbob: Most of my sandpaper is for power tools and such so the longboard isn't too much use to me.

I don't use a longboard just the sandpaper. it lasts long enough for the price.

Just noticed, 36" by 60 feet only $190 :o

What on earth do you need that for Larry ?

I don't, but my brother has a home made drum sander, wonder if it would work on that.

Reviewing how to make a semi permanent prototyping PCB using coring bits.

In this case ‘Thin Wall’ 9mm, 6.5mm and 5mm jewelry diamond coring bits are used to make the PCB pads.

It is important to spend the time to make a paper layout from the circuit schematic.

A 1:1 image of the layout is made using your favorite vector drawing program.

Make center punch marks on the copper clad PCB for each pad.

To prevent the board from moving on the drill press, place a silicone nonslip pad under the PCB.

Countersink/drill pads with the coring bits, about 1/3 the thickness of the PCB.

Add flux and solder the complete surface of the PCB.

Solder components as per your layout.

Note: 0-ohm 1206 SMD resistors are used as jumpers.

A jig to aid in making core bit pads.


The ‘Core Bit Drilling Jig’ makes drilling pads in copper clad PCB material quick and easy.

Attached images show all the materials needed and the use of the jig.

Your ‘work’ is sandwiched between a drilling template and sandpaper.

The jig holds the ‘work piece’ secure while drilling the circuit pads.

Silicon carbide sandpaper bites into the ‘work’ so it does not move.

Light downward pressure on the drilling template is all that is needed to hold the ‘work’ in place.

Make a 50cent 5v USB "flashlight" for light up tight spaces.

You need:

  • 1x 5mm LED diode
  • 120 ohm resistor
  • 1x USB module
  • two wires (22awg)
  • isolation from an old cable
  • some heat shrink

All possible tips have been provided.
There are no new tips that can be made.
Lets close the patent office too.

Hey, how do I vote.
This new post although 2 days old, only appeared as unread today.

I very much enjoy this thread. I never comment, but I have been subscribed to it for years and read every post. Thanks so much for making the effort to share your knowledge, and in such an excellent manner too!

As can be seen by post #892 and many more, you also inspire others.

Do to the new forum conversion process, many of the images in this thread were lost. If anyone wants something reposted, I have most of the images saved.

Please make a request here regarding the post # in question, I will attempt to recreate that lost post information.

Hi LarryD. I was very sorry to learn that this happened when you reported it earlier today. I immediately submitted a report to the powers that be at Arduino to be certain they are aware of the situation. I’m really hoping that this precious resource for our community can be restored to its former glory.

I was looking through the source of the posts and saw that some of the images that are still here seemed to have made it through the migration just fine. I realize that some of the remaining ones are here because they were hotlinked from external sites, but I do see others that seem to have been migrated. Do you have any ideas of what is different between them?

@pert

Unable to discern any differences in images.

If people want to see some of the missing images(not all), Google has some.

‘Some’ of the missing images. <-----<<<<

No no… do not close this thread! :slight_smile:
