Cool
Do you draw your own circuits by hand?

Would you like them to be 'pro' looking?

This is a very cool, and free, website that helps make circuit drawings. Check it out!

I have been using the schematic portion of ExpressPCB.com for years to draw my schematics.

I also use ExpressPCB, both to make the schematics and PCB artwork. Easy to learn. Easy to make your own components and add to the library.

I draw everything by hand. I used to be a draftsman years ago and really find hand drawing relaxing. Slow as it is, I like it.

I was doing a drawing with pencil and paper out in the yard last year, I was ca;;ed away to the phone and put my eyeglasses down on the board. I now get kidded that even doing electronic circuits on paper I can let the magic smoke out.
Regards,
Gerald.

If you draw your circuit board layout by hand or with a program, you will need to etch the board. I did a thread a while ago on how to etch circuit boards. If it's any use to those trying to create a board, here is the thread. There is a PDF file in the first post, that explains how to do it.

I had copied your PDF a while back haven't got around to making a board yet. I am reading a book on robotic (Arduino Robotics) and they have a chapter on making Circuit boards. They say that as an alternative to ferric acid you can use 2 parts Hydrogen Peroxide + 1 part Muriatic acid as an etchant solution. Another thing they use is glossy magazine paper as a toner transfer medium. They give a bit of a tutorial on using Eagle from CadSoft freeware version max 4" X 3.2" board.

Gerald.

I gave glossy magazine paper a try back then. It did not work to well for me that's why I went to the overhead transparency. Some of this is hit or miss and figure out what works best. Ferric Chloride is still available in the Radio Shack by me so I have my supply. Some places online sell it in powder form. You need to be very careful with any of these chemicals. I ruined a pair of jeans getting some FC on them, it just stained them. Muriatic Acid is just plain nasty.

I also have an Arduino and eventually have plans to control lights while a boat is on display. Basically use it to control lights going on and off in a timed sequence. I'll have to build a add-on board with relays to plug into the Arduino for this. And it will give me practice writing the code. Looking forward to doing this.
