PCB business key fob

Let your clients know you mean business when it comes to computers. Give them a business "card" that stand out from the rest. Inspired by the PCB bracelet, this novelty business card is unique and fitting if your services are computer-related. I operate a computer repair service that caters to the elderly, with my friend. We base our advertising on personal referrals, so the specialized business card facilitates that superbly.

I demonstrate how to cut and finish useless, old RAM sticks, but any type of PCB will work. The beauty of the RAM stick is that about a half is good for the business information and they come with a hole cleanly drilled already. This things are great for a key chain and clients are receptive to novelty of the card.

Step 1 Materials & Tools

This is a fairly simple task, but it does require a certain amount of concentration and minding of your own safety. If you take the right precautions, this is a fairly safe project.

To continue on safety, there are two dangers you should prepare for as you cut the RAM, or whatever PCB you decide on using. First of all, make sure to use a mask and work in a well ventilated area. The dust from the PCB is not good for your lungs and it does not smell very good. Be especially aware of the PCB dust when you are grinding the rough edges.

The second danger in this project is from your tools. If you are experienced with a hack saw and a rotary tool, you should be just fine, but regardless, these things can harm you, so be careful. When cutting and grinding the PCB's, always wear respiratory and eye protection.

Materials:

- Old computer chips (I recommend RAM, for size and dimensions)
- Labels or sticker printer paper

Tools:

- Hack saw
- Rotary tool
- Needle nose pliers
- Face mask
- Safety goggles (not pictured)
- Table vice (not pictured)
- Music (doesn't matte how it gets to your ears; it makes every project more fun)

if you use it as a business card for a computer repair shop, your customers might think you have a lot of broken ram chips lying around because you break em, thus repelling customers who have the same idea as this comment

It worked for me. Customers love them because it adds a tangible element to computer repair services, which are by nature intangible.

MENTION THE SAFETY BETTER. I just did it all in a small cramped room with no mask because I didn't notice that part in your instructable. Also, most PCBs, etc. have holes that are too small for conventional key rings.

You could put a small ring through the hole (like the kind you find on a keyless entry keyfob, or a swiss army knife), and then put the smaller ring on your larger key ring.

Neat Idea
