Panelizing and Gerber Generation in Eagle

Story I have been working with Eagle for quite some time but never really got a PCB manufactured. almost all the time i used the toner transfer method to make homebrew PCBs. But then i took a project in which i had to use SMD components and i could no longer use toner transfer method because of the limits on resolution of the Laser printer. Time had come for “properly” designing and generating “Gerber files ...

ECG Arduino Shield

Recently i made shield for arduino which can measure ECG, respiration, eventually after some changes in PCB and code, EEG and EMG. Big advantage of this shield is possibility to make it easily at home. The shield is equipped by display to show you measured signal real-time. Shield is based on AFE integrated circuit ADS1292R. You can use this shield for many application - acquiring your vital signs (or furth ...

How to measure mass of the Earth using Arduino

One fine day, I was weighing my self on a weighing scale. Suddenly a thought came to my mind, 'How much would be the mass of Earth?'. Leave that apart 'How can we even measure it?'. There is no such weighing scale on which, Earth can be placed. There has to be some indirect way to measure mass of the Earth. Here I present implementation of one such indirect method to measure mass of the Earth. Step 1: The I ...

Maker’s rule, the feature packed PCB multi-tool

It has been a while since i posted my Tinker Rule which i made during college days. I received a few requests for the ready to etch pdf which helped me gauge if this seemed to be useful to people. The response was somewhat positive and so, i decided to put in some extra effort and make it handy, portable and manufacturable ! My initial scale was big and not handy, So, this one should be small and compact an ...

Creating G-Code via EAGLE software

To create a PCB with 3Drag , by milling , it is necessary to have the G-Code files  for the tracks patterning and for the holes relating to the printed circuit board itself. In this section we describe how to obtain these G-Code files  using a specific plugin for the popular PCB design software ” EAGLE “. Note: This operation can be done only if the PCB you want was created with EAGLE . The PCB- gcode plugi ...

Making PCB Vias using conductive ink

One year ago some personal problems forced us to interrupt our hobby work, but fortunately we are back and we found some time to develop new ideas, projects and writings. At this moment we are starting the first feasibily testing of an innovative 3D printing method that we've named Resin Deposition Modelling (RDM). Personally I also hope it will be useful for 3D printing electronics using conductive resins. ...

Making a PCB Business Card

Many of you may have seen the Adafruit PCB ruler (also used by the awesome Voltera). The design was actually adapted from my own design back in University! To improve on the original idea, I have created a reference business card. Here is a computer render of the design: I wanted to show every common component I could think of, and how they relate. Often when zoomed all the way into a digital design, you ca ...

PCIs pelo método CNC – Making PCBs with CNC

Primeiro imprimia o desenho da placa numa folha de acetato. Essa folha era colocada por cima de uma placa foto sensível e colocada sob luz UV durante uns minutos. De seguida essa placa era submersa numa solução com soda caustica para retirar a pelicila foto sensivel que ficou "danificada" com a luz UV. A placa era depois submersa numa solução com ácido pre-coloreto de ferro. Após uma lavagem para retirar os ...
