Thanks to Arduino.cc. On December 31, my late Christmas present arrived at home. A Keithley DMM6500 - benchtop multimeter sponsored by distrelec. I won it at the ARDUINO / DISTRELEC: AUTOMATION & ROBOTICS CONTEST. This is how the year 2018 ended optimally. Contest and Sponsor Links https://www.arduino.cc/ https://www.distrelec.de/en
First test of my RTC Multiplexer
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
New PCB Order For My 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.
RTC 3231 first time use
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
Shift Register
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
Look what I found at the garbage
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
Mirror Foil Experiment
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
Keep Calm And Exterminate
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
Playing with my laser and acrylic
Experimenting with black painted transparent acrylic on my Epilog zing 16. Love the result 🙂 Here's another one, this time in blue
Small Alarm with Arduino QP
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
