Energy-harvesting power management ICs for wireless sensor nodes
Posted on: 15 Nov 2016
Cypress Semiconductor has introduced what it believes to be the lowest-available-power PMICs that enable an integrated module size of 1 cm² for solar-powered wireless sensor node (WSN) designs. Intended to manage solar-powered wireless sensors for Internet of Things (IoT) applications, these parts are said to be the lowest-power, single-chip Energy Harvesting PMICs, and can be […]
DHT22 Humidity datalogger
Posted on: 14 Nov 2016
There is a large cellar where I could store unused items and documents, but the catch is the humidity there. It is a root cellar near a small brook and the humidity varies between 75% up to 90%. Archived material should never be exposed to humidity greater than 65%, therefore I have to isolate all […]
How to control LM2596 buck-converter with microcontroller
Posted on: 13 Nov 2016
Those buck converters will change the output voltage to make the feedback pin, connected to the output via a voltage divider, become 1.25V or so. If feedback is higher, output gets lower and vice versa. If one changes the ratio of resistors in voltage divider, output voltage will change. This is usually done by turning […]
Kristall 511 solder wire won´t dirt your PCB
Posted on: 12 Nov 2016
You, who are at production of electronic devices, know, how important is a choice of a suitable solder. A designer of a given device might not focus on a solder used at soldering of the first protoype, bu tin a production it will manifest itself – sooner or later. Not that some solder would be […]
UT204 is able to measure DC current and also True RMS
Posted on: 11 Nov 2016
UT203 provides a lot of user comfort and a very pleasant feature – measuring of a DC current without interrupting a measured circuit. However UT204 is different from its “weaker” brother in one essential thing – it enable measuring of a true RMS value of alternating signals (TRMS). As we know, usual multimeters usually deploy […]
Tic-Tac TV Remote Jammer
Posted on: 11 Nov 2016
Pretty simple. Have a look at this picture above. The usual TV remote sends a pulsed IR signal which has some instruction encoded in it, like increase or lower the volume, or changing the channel. This remote jammer, however, sends a steady IR pulse at about 40kHz. This pulse has no data encoded in it. […]
PIC18 Development Board with Ethernet and USB
Posted on: 09 Nov 2016
In this instructable I’m going to show you how to make your own PIC18 development board that features both Ethernet and Full Speed USB 2.0 at a low cost. Features: The development board is based on a PIC18LF4553 microcontroller. The microcontroller features a Full Speed USB 2.0 (12Mbit/s) interface without the need for any external […]
Wireless Nixie Thermometer
Posted on: 08 Nov 2016
The Target of this Project was to learn how to use different functions of the atmega: • Connecting two Atmegas with a wireless connection • Each Atmega has a Thermometer (DS1621) to read the actual temperature • Use the sleep Mode of an Atmega • Controlling a Nixie bargraph In-13 And this all together is […]
WiFi smoke detector
Posted on: 06 Nov 2016
This is a simple WiFI Smoke Detector that texts me when it senses smoke. I made this for my battery storage area in case of a lithium polymer fire. I still have all of my regular smoke detectors installed and I don’t suggest relying only on this, but rather as an extra layer of protection. […]
Build a Motion Control Rig for Time-Lapse Photography
Posted on: 05 Nov 2016
If you dig around in your camera’s settings long enough, you’re almost assured to find that it has a mode to create time-lapse videos — those magical, time compressing movies that can turn any hillside or street corner into a lightning-paced dreamscape. Time-lapse videos by themselves are easy enough to make, but if you do […]
