Just ordered new PCB's for an idea. Start to build it on perfboard, but it was boring, so I decided to design PCB's. This time I tried jlcpcb.com. Let's check the quality. Normally they should reach my destination next week an I will post the result here.

Now that the shift register works, I connect a real time clock module to the Arduino. After a few fails, the RTC finally works. I changed the clock output to a 12 hour clock, an put the output on an LCD. In the next step,I used the 32bit shift register to make a binary watch. … Continue reading RTC 3231 first time use

A few years ago I created a PCB for a 32 Led shift register, but I never finished it. Now for a new idea it is needed, so I solderd it together.   It took me a while to understand how to configure the code for four 74HC595 shift registers in Arduino, but after a … Continue reading Shift Register

I found this cleaning robot in the recycling center This robot is a bad one, no stairs detection, no automatic charging base, and no rotating brushes. I think it will be a good platform for an Arduino bot. Let's look what's inside: I think this thing needs a brain, because there is not really one … Continue reading Look what I found at the garbage

I am playing around with mirror foil on Plexiglas, to make things appear when light shines on it. First test setupA small black painted box. The cover has a cut. I glued the foil on a piece of Plexiglas and fixed it inside.   When the LED is off, you can't see anything inside the box … Continue reading Mirror Foil Experiment

This is a quick Weekend Project. I wanted to test to engrave on glass, but I had the idea to paint it first black, to bring the picture more in scene. I still own a few old Ikea Ribba frames, the one with the glass front, so it was great for this project. Take the … Continue reading Keep Calm And Exterminate

Experimenting with black painted transparent acrylic on my Epilog zing 16. Love the result 🙂 Here's another one, this time in blue

Today I designed a small Alarm system with a PIR, a pizo sirene and my Arduino Quick Project. It was easy to build, so I had just to focus on the Code. When you switch it on you have 10 Sec. to leave the room. When now someone enters, the Alarm sounds. Not very complicated, … Continue reading Small Alarm with Arduino QP

Today I created a gift for a "Fallout" fan. A green lighted Vault Boy. The files can be found here Github or on Instructables First I created the Vault Boy in Inkscape. I used 3 mm cast Acrylic glass to laser the Vault Boy In Qcad and Inkscape I created the base, It's made out of 4 mm … Continue reading Fallout Vault Boy Led Light

The new board works perfectly. I will sell it as kit on tindie and on this website, so stay tuned. Thanks to PCBWAY for the high quality PCB's Now working on the enclosure. First design looks promising And the finished enclosure "blue edition" with the buttons. The pinout and the Lcd initialisation string information, are on … Continue reading Arduino Nano QP 4 with Buttons (update)
