Bbarney, Thanks again. I'm going to try photocopying onto the P&P paper later this week when I can get to a photocopier. Can you specify exactly the paper you use. I'm not sure what "regular inkjet paper" means.
As well as the Laserjet, I also have an HP PhtoSmart 7660 inkjet and use HP's...

Thanks for the concern and help. I don't think there's not much I can say about the procedure that would be all that revealing. I'm polishing the board with steel wool till very smooth and clean and de-burring the edges so the iron lays flat. I use a small piece of 3/8" thick alloy...
Hi
I'm in the middle of making a UV exposure unit and had thought of using glass for the platten. I read one of the posts here saying that glass was not UV transparent and that Plexiglass (Perspex?) was the correct material. Can anyone confirm this, please?
The Farnell ready made units used...
Hi
Many thanks for the detailed and helpful replies. I'll give it another shot since I have almost a full pack of blue Press-n-Peel to go.
I'll try cleaning with acetone and chamfer the edges of the boards which I wasn't doing before. I use a really good guillotine which cuts downward from...
Hi
I've been trying out the blue Press-n-Peel transfer method at least 20 separate attempts all with very disappointing results. There's always ripped tracks or holes here and there. Before I give up on it completely, can anyone suggest what I am doing wrong?
The first sheet I printed was on...
resistors for fuel gauge
Techie, many thanks for your help. One last question I promise!
I used a spare 500 ohm pot to simulate the sender. One end of the track goes to Vcc, the other end goes to GND and the wiper goes to the signal input of the LM3914.
This works fine but without the...

Hi
Thanks for the reply. Would you be able to give me a bit more detail? I'm afraid it's not that simple for me as I'm sure it is for you. What is the "fuel gauge" you're referring to? There isn't a fuel gauge. Do you mean the sender? Sorry if I'm being stupid.

Dear All
I want to build a fuel level gauge for a motorcycle using a 10-segment LED bar graph operating from a standard LM3914 driver.
The input signal to the driver IC is 0 - 5v so if I connect a bench power supply to it, and vary the voltage up and down from 0 to 5 volts, the bar graph...

Thanks for the reply. Sorry to ask another dumb question but how do I "mirror" a component with AutoTrax? I know how to rotate but not how you mirror.
Regards
Trevor
Hi All
Sorry if this is a really dumb question. There's probably some obvious answer that I can't see.
In Autotrax 1.61, when placing an IC library component such as a DIP14, the rectangular pad indicating pin 1 appears to be on the wrong side. In other words, if I'm looking "through" the...
