Finally my orderd PCB's from jlcpcb.com are here. They have a very good quality for my prototype and with these PCB's I save a lot of time in wireing Today I soldered the most parts in place. It took me a while,why the LED^s didn't work, but there is an error in my design A … Continue reading First test of my RTC Multiplexer

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
