Plugable USB 3.0 UGA Display adapter
Today I’ve received the Plugable USB 3.0 UGA multiple display adapter. Using this device you can add multiple displays to Windows systems and also Apple Mac OS X systems. Mac OS X support is added recently so most of the sites still state that only Windows is supported. It can connect to DVI or HDMI display.
The device uses the Displayl [...]

Arduino DIY – Software updates
At the moment I’m still working to improve the DomoticaBox, SensorBox, Wireless LCD Display software. Once I have a new complete matching set that is suitable for download, I will update the links on this site again. Some improvements are:
Watchdog to auto reset in case of lockups
Use EEPROM for storing Open.Sen.Se feedID’s for t [...]
RTC timesync to Arduino
I’ve added some new code to the wireless LCD Display and my Raspberry PI to set the time on the wireless LCD display correctly and regularly.
The wireless LCD Display has a DS1307 RTC connected but it is not the most accurate so time will shift after a while. The Arduino time library has an example on how to set the time using the seria [...]
Sensor Box
I’ve been working on replacing the 433Mhz cheap transmitters (send only) by the RFM12b 868 Mhz Transceivers (send & receive) by using the RF12 library from jeelib.
Things are working now, but it’s quite a bunch of work to convert all devices .
Also I’m very happy with the Attiny84 microcontrollers which allow some low p [...]
Notification when host unavailable
I needed a solution to check every x-minutes if my IP camera is still online.
I use the Pushingbox.com service to send a notification when a certain host is not available. Checkout Pushingbox.com to see which kinds of notification services they offer. At least a notification to email and Prowl! is possible.
I’ve combined the python scri [...]
Phone notifying doorbell with Pushing...
The sound of our regular doorbell isn’t heard everywhere in the house. Also, sometimes you know that somebody has been at the door but you don’t know who. I found the article below in which especially Pushingbox.com took my interest.
Pushingbox is an online service which you can trigger from an Arduino microcontroller very easy. P [...]
Energy monitoring with Arduino
Since we’ve bought a bunch of solar panels on our roof, I’m building an electricity monitoring device based on the Arduino microcontroller.
It’s running for a while, monitoring solar power generation but now it can also read the Smart energy Meter which we got from the energy company. So currently it reads and/or calculates [...]
Updated URL structure
I’ve made an update in the way this site uses URL’s. Before it used URL’s like: http://www.vdsar.net/archives/114
As of today I’ve modified the site to use URL’s with the postname in it. Like: http://www.vdsar.net/how-to-add-a-ssl-certificate-to-your-synology/
It might take a while until the new URL’s are a [...]
Solar panels installed
Since september 20th we are the proud owners of 13 solar cells on our roof with a maximum peak of 3120 watts. This should be sufficient to cover at least 50% of our electricity consumption. The panels ‘look’ towards East-South-East.
For who is interested, the brand of the panels is Komaes 240 Wp. The invertor is a Diehl Ako 3100s. [...]
