Hello, my name is Nic. I'm in grade 10 and I have an interest in electronics. But I have a lot of restrictions. I live in Canada in a town where there is no electronics shop other than "The Source" (Radioshack was bought out by The Source) which sells overpriced components that aren't the greatest quality, I'm far away from A1 Electronics which is a brilliant store in missisauga. And There is no Electronics course in my high school. But this hasn't stopped me.
I scavenge for parts from broken electronics I find around the house or that are given to me from friends, I am self taught thanks to books I've bought and Make:'s "Make: presents" series. But my biggest problem has been circuit boards,
The source does sell perf board (protoboard, or hole board, same thing) but it has a tendency to burn and it is a bit expensive compared to the A1 perf board, and the source doesn't sell copper clad board or etchin. So I was looking at the piles of PCBs I had acquired from Electronics I had taken apart and I thought "could I make them into my own circuits by taking advantage of the board somehow".
And so I figured out that I could help Reduce E-Waste and solve my circuit board problem at the same time.
Step 1: Gather your Tools
1) An old PCB
2) A soldering Iron
3) A desoldering pump, or desoldering iron
4) Rubbing Alcohol and a rag
5) A Dremel or rotary tool with a sanding disc
6) Some very small drill bits
7) Exacto knives and a utility knife
8) Solder to Tin your iron
9)A continuity tester
10) a Sharpie marker.
Step 2: Desolder the Board
Step 3: Clean The board
Step 4: Sanding the Board
Once you're done clean the rest of the dust from the board with more rubbing alcohol
Step 6: The Preset Method
-requires little work
-placing larger pieces with complex leads such as IC sockets can be troublesome and can be left up to luck with the board you choose.
-solder bridges can be common if two holes are close to each other
Step 7: The Slice Method
-The circuit is better designed and can be set to your preferences
For my example I'll use a mix of both methods because its the most effective way to make your circuits.
Step 8: Building My Example
I started off by scoring the board with a utility knife so I could make the board smaller and more compact and less confusing.
Then I used the exacto knife to cut a contact into two parts. Whenever you cut a contact always use the continuity tester to check if you cut the contact successfully.
after cutting the contact I drew out the holes to be drilled with a sharpie.
I then set up my dremel with the smallest drill bit and drilled on the marks
Then for instruction sake I drew out how I would link the circuit so you can get the idea on how I do this.
Step 9: Use your old boards and reduce E-Waste
Although this may not be as good a copper clad boards and etchin it still works well for me so enjoy and I hope you enjoyed y first instructable.
