Wizkers.io embedded server rolled out in Bodega Bay

What could be better than a harsh marine environment to put hardware to the test?

On September 9th, we installed a new radiation sensor for Safecast.org at the UC Davis Bodega Marine Lab. This sensor connects to a box that runs wizkers.io as an embedded server on a Raspberry Pi, and uses the International Medcom GeigerLink - also designed by the Wizkers.io team - as the sensor interface.

Wizkers.io makes installation of such embedded sensors especially easy, thanks to its Bluetooth Low Energy interface that lets the installer configure all key parameters using a simple Android app, including discovering the IP address of the box.

For this particular installation, Wizkers is streaming the radiation sensor data to the Safecast real time monitoring system that is updated every 5 to 10 minutes, and simultaneously streams to Dweet.io for  updates every 30 seconds, including internal CPU temperature.

You can read more about the installation on the Safecast Blog.

We are looking forward to seeing how our hardware and software are doing in this difficult environment!

Wizkers.io powered app on the Apple Mac App Store!

This is an exciting bit of news: the first Wizkers.io-powered Mac app was just approved by Apple for selling on the Mac app store.

You can now search for "Wizkers Radio" on your Mac's store and install it directly from there:

This is also a great milestone for the Wizkers.io framework, since Apple's review process is fairly strict, and this demonstrates our framework is mature enough to build official Mac apps.

You can visit the Wizkers.io support forum at http://forum.wizkers.io/ for a more complete discussion on this release.

From a technical standpoint, the version of Wizkers:Radio that is on the Mac app store is the standard Wizkers:Radio code, powered by the NWJS.io framework. This comes right on time with our development schedule since Google has decided to remove support for Chrome apps in early 2017, depriving us of that convenient distribution model.

The Apple Mac app store is a great replacement for Mac users though, with a version of Wizkers:Radio that you should find faster and snappier than the previous Chrome version.




Telepost LP-100A support

The latest version of Wizkers adds support for a new instrument: the Telepost LP-100A:

This new instrument is a really cool RF Wattmeter with a lot of interesting capabilities. You can read all about it on the Telepost site. The LP-100A supports a simple serial data output, which made it an ideal candidate for Wizkers:Radio.

This first implementation is a fairly straightforward remote display for the LP-100A which mixes a semi-realistic rendering of the actual device and controls in the usual Wizkers:Radio tradition, but takes a few liberties to present more information than the LP-100A itself can do on its 2-line VFD screen.


The following LP-100A capabilities are supported:

  • SWR Bargraph
  • Power bargraph (15W, 100W and 1500W autoscale)
  • Alarms: visual and audio with a 600Hz annoying beep
  • Alarm setting and Peak/Avg/Tune setting
  • In a nutshell, pretty much everything the LP-100A will let you do remotely.

The bargraph update speed is at 2Hz right now, with very little CPU usage. It is probably not practical to go above this value, display-wise, but we are open to comments.

We are especially pleased with this new instrument, because this fills a gap whereby the only OS that was supported by the official Telepost utility was Windows. You can now remotely display your LP-100A on pretty much every device on the planet - save for iOS, but that's another story altogether.

Many thanks to Larry Phipps from Telepost for his support on this project!



New radios in Wizkers

We have just released Wizkers:Radio version 0.2.0 which adds support for a Yaesu radio for the first time: the FT-817 is one of the most popular QRP radios, and we now have basic support for it, including a pretty nice rendition of its LCD screen.

From a software standpoint, this also means that we can now support any other kind of radio - as long as we write the drivers for them, of course.

We have also added support for the newly released Elecraft KX2, which is a very close cousin of the K3 and KX3, which means that it was fairly simple to support it as well:
