RF Explorer is a remarkable diagnostic tool used for monitoring and troubleshooting wireless systems and communications. It is a new series of low-cost, portable, RF spectrum analyzers designed by Ariel that are available in a variety of frequency ranges.
The RF Explorer series of analyzers re-defines the handheld, portable RF spectrum analyzer. The unit is small and light-weight, yet offers performance and features comparable to larger, more expensive devices.
Whereas once the use of RF spectrum analyzers were limited to companies/organizations that could afford their high price tag, the low cost of the RF Explorer now offers every engineer, technician, and savvy hobbyist the opportunity to own an RF spectrum analyzer.
Below are 3 software applications you might be interested in — they run on Windows PCs. This allows you to experiment with the various features provided by the software and determine which best fits your needs:
3 Software Options for RF Explorer
1. RF Explorer for Windows PC Client (free)
From the developers of RF Explorer, the RF Explorer for Windows PC Client application provides traditional spectrum trace views along with more graphical waterfall views.
2. Touchstone Standard (free)
3. Touchstone-Pro ($49 USD)
Touchstone software, from Nuts About Nets, turns data collected from RF Explorer spectrum analyzers into highly graphical charts and displays, enabling users to more readily visualize the RF environment, monitor RF signals, troubleshoot RF issues, and detect sources of RF interference.
This is a short clip of the featured staffs we saw in CHTF 2014.
We spend an afternoon wondering in SZCEC (aka Shenzhen Convention & Exhibition Center), seeking robots, 3d print machines, industrial controllers in hi-tech faire this year.
THE CHTF is an annual event on biology devices, new energy, electronics and advanced manufacturing.
Here’s something cool staffs here we’d like to share with you.
Football is quite popular on LEGO like robot platform, this is a group of robot kits by a education company. Based on wifi, you can control your robots on your phone, quite interesting.
Multitouch screen, the basic ability to draw lines with different kinds of pens. It remind me of Paper53, the app on ipad with better drawing experience.
What a wonderful and well packed personal solar panel system, hiding all the dirty wires. Just go outdoor and use it as a normal charger (like a black box), you don’t have to understand what it is and how it works.
A group of environment sensors which are very like to be placed in house. Though they look ugly, bad user experience, there’s still a market for integration house service if you make good use of them.
Another ugly design of wearable hardware. It is used for taking the body temperature of new born baby, the hardware is connected to ipad etc. So the data is streaming to CLOUD through ipad. An alert service is what the team provide rather than the hardware itself. Anyway, the idea is great but the product needs improvement.
Another example showing the trend in home health care devices integrated with Internet. Based on your daily data, a doctor will keeping an eye on you remotely.
Since the pebble last year, a large group of “smart” watch is coming to the market. The picture shows a GPS enabled watch for children security, the feature is to get the location by buildin GPS and a single way real time voice monitor by buildin GSM module. China faces a great problem of child abduction, this watch is just design aganist such crimes.
What a cute droid!!! Android is quite popular in China because it provides low-cost smart phone solution.
Very much similar to a kickstarter project, you don’t have to throw it into the sky to get the panorama. There are totally 30 cameras on such small part.
Industrial robots are among my favourites. This one shows a noticeable improvement in handwriting, both Chinese and English. As a Chinese, I have to admit his writing is better than the average, even some beginner students in this area. A lacking in the spirit of typical Chinese handwriting is the biggest problem, that’s because robots don’t have souls and emotions, all the steps are controlled by the program, which simulate a patten setting by humans.
Another remarkable area is open for individual who invents by himself. The homebrew inventions are not good enough, but I still admire them putting lots of time focus on a subject though they may not get any pay from what they learned. Compared with CHTF, I still like Maker Faire much because people are more likely to share there, instead of getting a patent.
Another wired display rack, which can move.
There is a displacement sensor inside the device, an interactive game based on hardware and it’s quite clear to understand what happen. The model is our industrial designer: nosk. ^_^
Finally, it’s still worth spend half day there exploring. There are more info from the official website (ugly designed but in English): http://www.chtf.com/english/.
See you next year.

Creating a SubGHz RF sensor network with a WiFi gateway.
In this demo, we created several wireless sensor nodes. Each wireless node features a unique sensor from Seeed Studio, which interfaces to a TI LaunchPad + CC110L Sub-GHz RF BoosterPack + Battery BoosterPack. The SubGHz-to-RF Gateway was created using the CC3200 WiFi LaunchPad paired with the CC110L SubGHz RF BoosterPack. This was all programmed using Energia.
I have always enjoyed science, engineering and computers. I am not a professional engineer and I am very open to input and suggestions as I see this primarily as a learning opportunity for me. Please take a look at this documentation and feel free to let me know how I might improve this project.
As someone who likes to spend time outdoors, I have sometimes wondered whether the air quality – at the time and place I am – is suitable for strenuous activity. In this regard, I am lucky as some people are sensitive to certain pollutants and need to worry about their exposure for even routine activities. I saw in this an opportunity to pursue some “citizen science” and continue to learn about how to build sensors and embrace the internet of things. I am documenting this project with two goals in mind: 1) to engage others to critique my approach and suggest improvements and 2) to provide all the information needed to build and extend this project.
- Build a sensor which can give consistent (accurate) results. Precision will be a stretch goal as it will require calibration tools I may not be able to get access to.
- Sense a range of different gasses based on the module selected and compute an “Air Quality Index” for each
- Use a standard interface – i2c – so it can be used with different systems. My first application will be with the SeeedStudio LinkIt ONE
- Support portable operation on battery power using GPRS for data reporting.
- Report all data to an Internet of Things Data streaming site for reporting.
Phase I – The Sensor Board
I started with the board as the sensor I wanted to use is a surface mount device and I knew that making the custom board to support it would have the longest lead times. I have completed the rough design and have not yet sent the board out for fabrication so now would be a great time to take a look and let me know what I am missing. Here are the major elements and their function:
- Gas Sensor – I found a distributor for SGX Sensortech Limited who carries a complete line of Metal Oxide Gas Sensors. There is a family that all share a common footprint so you can select the sensor you want to use. Here is dual CO and NO2 sensor that I will start with.
- MICS Quick Start Board – This is where I started butI decided that I could design a much more functional board for less than what they were charging.
- Temperature and Humidity Sensor – I chose the Honeywell,HIH6130 as it was compact, i2c and 3.3 and 5V tolerant.
- I wanted to control the board with only 6 wires, two for a 3.3 reference, two for i2c and two for control – on/off and preheat/fan. To do this, I added a Fairchild inverter which would alternately pre-heat the sensor or turn on the fan via a pair ofNXP N-MOSFETs.
- Digital to Analog Converter – I have to admit, I have a bit of a digital bias. By converting the Gas Sensor’s readings from analog to digital, I could use less wires and run the sensor board at 5V while my main board runs at 3.3V or 5V. I used a TI four channel Digital to Analog Converter with two channels for the Gas Sensor, one to measure the battery voltage and one routed to a header for future use.
- i2c Level Converter – Using this converter, you should be able to use this board with either 3.3V or 5V i2c as the logic level for the output header is set by the two wires you feed from your controller. Have not done this before, but it seems straightforward. I used the TI Bi-Directional i2c device.
- Power Supply – This was one of the areas that drive me to design my own board in the first place. The quick start board used a simple linear supply but I like the switched TI TPS63002 as it allows for a wide range of battery voltages and takes only a few components. One nit, the PowerPad chip is hard to solder and I had to create a custom footprint as the ones TI gives you are junk.
Here is the schematic for this board:Air Quality Board
Update: Finalized the board and sent to OshPark for production. Here is what the board will look like:
I do the board first as it takes the longest. I will now order the remaining components and the sensors from SGX. While I am waiting on the atoms, I can start working on the bits. I have a GPRS modem from Adafruit to play with while I wait for the LinkIn ONE to make it’s international trip.

What a creative and good-looking lego case for Linkit ONE , it is created by Sam Hetchler.
“The first version was taller, but this allows to have a full block height back. It contains GPS antenna ,Wifi/BT antenna ,GPRS/GSM antenna and Li-on battery in a box.The Lithium Battery is under, as you can guess from the wires tucked back under” Sam says
and the updated layout is coming
“The board can still wiggle around a little. The antennas are not in the best place for the connections, and the SD card still needs work around it so I can get it in and out without much effort. My first desgn didn’t allow me to get the SD card out at all”
Sam, really good innovation!
The trip in shenzhen involves:
- Chaihuo Makerspace
- Shenzhen Factories
- Local(Huaqiangbei) electronic market
During the visiting in mold factories, I took some of the video on how machines are working, here’s the youtube:
