Making circuit boards with DLP projector

IMG_5092-1

Nuri ERGİNER managed to create his own PCBs using a DLP projector and photo-resist dry film.

Every Maker like me dream a PCB printer which can quickly and precisely convert our electronic idea into a psychical circuit board. I know there are plenty of project going on the subject. (see the end of the article) What I tried here is something different, quick and precise. If you have lots of electronic idea in your mind and most of them have a high probability of fail, the system must be quick and easy.

Nixie Tube Energy Meter

John Whittington decided to build a Nixie tube energy meter to measure his house power consumption.

 An Arduino would be the microcontroller but I wanted the meter to provide some form of data stream for a web based energy history. To make it an IoT, I a paired ESP8266 with it. I used both together because the Arduino ADC has a better resolution and has been tried and tested.

Teensy 3.2: A first look at the powerful Arduino compatible board

educ8s.tv reviews the Teensy 3.2 Arduino compatible board and examines if it’s compatible with his existing sketches.

If you need a small but powerful Arduino board, Teesy 3.2 is the best board available today. In this video we take a first look at Teensy 3.2 board, we set it up and we run the blink program. Next we try the code of a previous Arduino project to see if it is really compatible.

Lead Acid Battery float charger

Nobilis @ instructables.com has build a lead acid float charger out of an old phone wall charger:

If you do not use your motorbike on the winter or your car stands for weeks — you better have a float charger connected to the battery. Otherwise you probably encounter engine starting problems, and your battery’s lifetime is getting shorter. In a depleted battery the emerging sulfation on the negative plates is avoid the battery to take adequate charge again, and a vicious circle happens: the battery is unable to get fully charged, which increase sulfation, which avoids proper charging, and so on, until your rather new battery is ready to be recycled.

Better 3D graphics on the Arduino – ILI9341 LCD

Montage

M Rule @ crawlingrobotfortress.blogspot.com discuss about ways to optimize 3D rendering on ILI9341 LCD and Arduino:

Both optimizing ILI9341 LCD drivers and rendering basic wireframe meshes have been done before. XarkLabs provides an optimized fork of Adafruit’s library. Youtube user electrodacus has also implementd an optimize driver for the ILI9341 communicating over SPI.
