Its been a while i was searching for a cheap wifi module and with the help of smart-prototyping.com, i was able to get a module almost less than USD 5. To connect the module to breadboard for prototyping, i made a small jig to interconnect with the board easily. So i can wire up the […]

Introduction The project use a custom printed circuit board for the charge controller power management electronics, and requires an external Arduino pro mini to run the control firmware. The power management board design has the following features: PV input transient and reverse polarity protection Sensing for PV input voltage, converter output current, load current, and

The IEEE 802.15.4 standard is the fourth task group of the IEEE 802.15 working group, which defines Wireless Personal Area Network (WPAN) standards. The IEEE 802.15.4 market has the following advantages; low power consumption, low cost, low offered message throughput, supports large network orders up to 65k nodes, low to no QoS guarantees, and flexible

This is something I’ve already worked on but was never really happy with the result, mainly because the potentiometre that I used was of poor quality and hence non linear and “jumpy”… The problem is simple: I need to have a reliable and easy to use servo tester, that I can use to test/play with a

In a recent instructable Indigod0g described a mini weather station that works pretty well, using two Arduinos. Maybe not everyone wants to sacrifice 2 Arduinos to get humidity and temperature readings and I commented that it should be possible to do a similar function with two Attiny85’s. I guess talk is easy, so I better

Step 1: Connections First let’s connect the Nokia 5110 display. Remember that the LCD runs on 3.3V and although some people have connected it to 5V, it has worked but gave some weird effects, so I suggest connecting to the 3.3V output of the arduino. Next, the LIGHT pin on the LCD. It is the

The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heater, or separate. Here is a short list of features: – power: 9-28V, AC or DC – 2 separate heater control channels –

When you think about Samsung, the first products that come to mind are probably phones or televisions, not Maker-focused electronics. Today, with their announcement at Internet of Things World, Samsung has entered the Maker world with their ARTIK platform, an Arduino compatible family of devices targeted towards Internet of Things applications. Currently there are three
