Here I will put random links. The main reason for that, is I'm on different computers, and I do not want to bookmark everything everywhere.
Decoupling and by pass caps...
I got inspired by one of the threads on the forum, and that ended up with this. My way of making a workbench/bread board powersupply.
The input source is a wall wart 30v 1.5A.
It's limited to regulate down to 12vdc and 5vdc. Nothing more and nothing less.
I design my schematics in Eagle, here...
When you design a board, you might want to have a few exact copies of it. In Eagle, there is a way to make multiple boards, on one sheet of paper or transparent.
This is the way I do what is called Panelizing.
1. Design the board
First things first. While making the schematic, I have...
I've always thought that SMD soldering is hard. And I guess it is, when it comes to advanced circuits and SMD ICs.
I had my first try this evening. Both with SMD soldering, and etching with Ferric Chloride.
I've etched a few boards, and I've used Natriumpersulfate, at approximately 50°C. Lot...
This is a question that comes to the board, from time to time. I decided to make a list over some PCB manufacturers.
Usually a post starts with one of these questions:
"Where can I get boards done?"
"Who is best?"
"Which is cheapest?"
"Which is fastest?"
"Who can I trust?"
This is a listing...
Making the PCB
With reference to this article:
Projects from A-Z. Part 1.
To transfer the boards graphic to a PCB, I'm using the UV method. I bought some UV-LEDs on Ebay, and made a little circuit that controls them. (On request, I will make an artice of my exposure box.) This is my...
Finding the project.
This is part one of two articles.
So how do I start a new project, and how do I decide what to build?
Whenever I come up with an idea, I write it down. I have a long list of "projects to-do". It reaches from a simple LED flasher in the bushes, to a more advanced circuit...
