DIY-Thermocam – an open-source, do-it-yourself thermographic camera

Posted on 8 January, 20168 January, 2016 by mixos

Max Ritter has pointed us to his latest project, the DIY-Thermocam, a open source thermal imager based on FLIR thermal sensor. The results are awesome!

The device is based on the popular FLIR Lepton thermal sensor and uses a Teensy 3.2 mikrocontroller to display live thermal images on a nice 3.2 inch touch screen.

The aim of the project is to give private persons, educational institutes and small companies access to a low-cost thermographic plattform. Offered as a selfy-assembly kit, the DIY-Thermocam is easy to build and use, you just need a basic soldering iron and some tools everyone has at home. The whole firmware is published on Github, so everyone can contribute their own ideas to the software development.

ESP8266 weather display – work in progress

Posted on 8 January, 20168 January, 2016 by mixos

Markus Hirsch is working on a ESP8266 weather display using an AVR mcu and an OLED display:

This is a little weather monitor. It has a 2.2″ color display and is powered by an AVR and the ESP8266. The AVR controles the display. The ESP has a custom firmware written in the Arduino IDE and provides all the weather data in a neat and very simple pre-parsed protocol. The AVR can obtain different data via a simple UART command. It is still in development. A 512kB serial SPI flash provides all the icons, images and palette data.

CSI Premier 75W and Hakko 936 Solder Station Teardowns

Posted on 8 January, 20168 January, 2016 by mixos

Todd Harrison @ toddfun.com did the teardown of the CSI 75W solder station as well as the Hakko 936:

The Hakko of course had all analog circuits using operational amplifiers and potentiometers as well as a temperature sensor in the iron tip to signal back to a triac chip controller which would trigger the triac to push 24 V AC through the heater in the iron.

Making circuit boards with DLP projector

Posted on 8 January, 20168 January, 2016 by mixos

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

Posted on 5 January, 20165 January, 2016 by mixos

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

Posted on 4 January, 2016 by mixos

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

Posted on 4 January, 20164 January, 2016 by mixos

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.
