Remember the movie “Edge of Tomorrow“? (also known by its marketing tagline Live. Die. Repeat.) Cage is killed in combat, he finds himself in a time loop that sends him back to the day preceding the battle every time he dies. Kinda like the ESP8266 when it repeatedly resetting… Nothing you try makes a difference! […]

Hand soldering Surface Mount Devices (SMD) scares a lot of Makers, but it is easier than what it looks like. Even sometimes, it’s easier than soldering Through Hole Components. Really! The Components are naturally held in place by their legs, while SMD are just sitting flat on the PCB, only waiting for the smallest PCB

In my previous blog I covered the hardware and software and part II here for my Raspberry Pi® – Powerunit® project. Now its time for the PCB Design. KiCad Although KiCad (pronounced ‘Kai-Cad’, not ‘Key-Cad’ like the thing that goes in a lock) is the new hotness when it comes to PCB design. The amazing growth

How to program a ATTiny I discussed in my previous blog here. But I want to go even smaller! In stead of using the “big” DIP IC housing I wan to use the smaller SOP IC housing. But then I realized how to program these tiny things, they don’t fit on a breadboard. But first

One thing that was still missing for me on the Raspberry Pi®, was the inclusion of some kind of power switch or Powerunit ®. Considering how many common Raspberry Pi® projects could make use of this functionality. Still, we’ve lived with this problem with the old version for a long time, and there are plenty

For an upcoming project I need to improve the electrical characteristics of the PCB by increasing the width of the Ground and Vcc tracks. Let’s start with the track width. You can control the width of each track manually. The method involves creating custom track’s widths and then applying one of those to a new

For a new project, I was, once again playing around with Kicad, the new version has received a lot of changes, improvements and additions again. For my current project I need a Raspberry Pi Zero W template that is not included in Kicad as standard. So time to make it myself. Project templates Using a

In one of my previous posts (ATTiny85), I detailed an ATTiny85, or in my case the ATTiny85 SMD chip. These chips are al the same only the package is different. In this blog I will use a ATTiny that is breadboard friendly in combination with a I2C OLED. I2C OLED OLED 0.91 inch is a

I have some Philips® hue lightning bulbs in my home. To operate these lights they need permanent power, wall switches have to be always on. So when I go to bed and turn off the wall switch the light will never shine again if the hue bridge try to switch on the light, for example
