Playing around with sketchup 8 to design a new led lamp. The pilot will be a robot or an alien 🙂 Robot and cockpit design First Cockpit and Pilot cuts

https://youtu.be/DdODKQxkLG8 Playing with the with a motor controller L298n. Took me a while to understand the datasheet. It's not the fastest robot, because it still runs on 5V. The motors need 12V in normal use. Now I will connect a bigger battery and try the PWM on my Nano. Stay tuned

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  

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
