Not to be too critical I hope, but if you're going to take pictures like that, please invest in a desktop tripod =) You can get them for less than 20 dollars in the states, not sure about in the UK. They're hardly bigger than a camera bag collapsed and increase the quality of the shots you can take big time.

The poorness of the picture's is a combination result of my unsteady hand, and also I took the picture with my camra phone (Sony Erricson K750i), for me the idea of a nice dedicated digital camera is but a distant dream, I am a student after all!

A better camera will not help if you can not hold it still. Try resting you elbows on somthing while you take the pic. Holding you breath can help too.

Maybe put the board on the seat of a chair and rest your elbows/arms on the back. Position the board to reduce glare if needed.

Suggession needed.
I started PIC programming a month ago. I make all the circuits with PIC on BreadBoard.
I am using PIC16F877A for my practice.
Now i want to use a devolpment board. also have a ICD2 connector for Inchworm.. Cheap also.
Where can i buy these boards?? Must be cheap.

 

Any PCB prototyping board with 0.1" standard spacing will work. The ICD2 connector can be as simple as a row or double row of 5 pins.
I'm looking in to a generic PCB same size as the inchworm PCB for just as you described.

Opps, development board. What would you like to see? I'm working on a larger Dragonfly style unit (16F877, 16F887, 18F4550) with LCD, 3x4 Keypad, RS485 and 300 hole solderless breadboard. Is that the sort of thing? Of course firefly is a simple tutor system

I make this for me.
Now the problem is hot to transfer it on my Copper coated sheet..
I make it in PCB123

You should add a couple of 0.1uf caps as near as possible to the PICs power pins. The Inchworms powersupply can supply your board with up to 800ma.

Looks good to me, I'm knocking one up on a protoboard (tripad) I got from ebay, jsut while I wait for my PCB's to be made for 'the beast' board (which I spent far too long designing).

You could use stripboard if making PCB's is a hassle? The convenient thing about most micro's, especially PIC's is the pinout, most ports are in the correct order on the pins. Any 'odd' placements you can use jumpers, or wirewrap wire under the board to connect. Might not be easy for complicated designs, but for bringing I/O's to headers, providing power, a clock, and a programming header, it does the job. Plus you can easily design stripboard in a CAD software, like eagle, or PCB123, just remember which way the tracks go (left to right for your picture) and marks any track cuts.

That said, ebay has many dev boards, with and without components. In fact, if you google 'development board PIC' and use the 'images' to narrow down the search, I'm sure you'll find those nice little protoboards which give power, rs232, programming header (ICD2, ICSP etc..) port headers and a prototyping area for around 12UKP (23USD I ithnk..). I made my own because I like special headers for certain things, like nokia LCD's, but apart from that, it'll do everything you need.

Hope this helps, (sorry if I repeated anything),

Something intrsting

 

For free you can do this process DIY PCBs

I you want to skip some of the trial and error and use a more fool proof system you can use the this method for less the 5 cents per square inch.

First board made using 15 minute method
