Tweet Ik ben nu net een keer te vaak op zoek geweest naar functies om WGS84 (4326) coordinaten te converteren naar Web Mercator (102100) en andersom. Daarom heb ik ze hieronder neergezet voor iedereen die ze ook vaker nodig heeft. De functies komen van ESRI: private void ToGeographic(ref double mercatorX_lon, ref double mercatorY_lat) { if (Math.Abs(mercatorX_lon) < 180 && Math.Abs(mercatorY_lat) < 90) return; if ((Math.Abs(mercatorX_lon) > 20037508.3427892) || (Math.Abs(mercatorY_lat) > 20037508.3427892)) return; double x = [...]

Tweet To follow up on my previous post, the news is that I have successfully dumped all firmware parts of my camera. The bad news is that it didn’t work on my camera. The problem is this: audio_dev.state not AU_STATE_RECORDING wb_audio_start_record inet_sr.c INET_rinput 321 action===1 options==33 inet_sr.c INET_setroute 75 *args===255.255.255.255 *args===netmask *args===eth0 [29] write i2c error write i2c error write i2c error write i2c error write i2c error write i2c error write i2c error write [...]

Tweet I recently bought a few of these camera’s: http://www.chinavasion.com/product_info.php/pName/ip-surveillance-camera-with-angle-control-and-motion-detection/ There not very good, but for that amount of money what can we expect! After installing the cams and playing a bit with them the natural urge to flash the latest firmware to a device came over me. I looked at the site of China Vasion, but could not find anything of a new firmware. A bit disappointed I search on google and found out [...]

Tweet I have created a one click firmware updater for the Netduino! The tool was initially build by forum user Randoom for the FEZ Devices. I took that code as my base and created the Netduino One Click installer. It detects a Netduino automatically and reads the currently installed firmware version, after that the tool will check on a remote site if there is a newer version of the firmware available (currently it is my [...]

Tweet I decided to take the ultimate challenge, at least for me, and that is that I am going to build a FEZ Domino from scratch, well not exactly from scratch, but anyway. I downloaded the schematics and PCB layout from the TinyCLR.com website. Next I went to my favorite PCB house Seeed Studio and ordered 10 PCB’s. I placed my order at the 14th of September, the boards where ready and shipped the 19th. [...]

Tweet New VS 2010 Productivity Power Tools Release I recently discovered a brilliant extension to the tool that we developers use on a daily basis, well maybe not VS2010 but ok. The Visual Studio 2010 Power Tool Extension adds a lot of really helpful functionality!  You can download and install the release for free here.  Some of the code editor improvements it provides include: Entire Line Highlighting: Makes it easier to track cursor location within [...]

Tweet In my last post I talked about a opensource .NET Micro Framework development platform, in the Arduino form factor, the Netduino. The Netduino is not the only .NET Micro Framework development platform there are many, many more. But few are as affordable as the Netduino. On board that is also relatively cheap are the FEZ Panda and FEZ Domino boards. Both boards are in the Arduino form factor. Where the Netduino is based on [...]

Tweet If you are into electronics and you are a .NET developer then this thing called the Netduino is something you might find interesting. The Netduino is in the same form factor as it’s smaller (CPU wise) brother the Arduino Above is the new Arduino Uno Today I received my Netduino package! A nice blue box. Inside is the Netduino board. Ofcourse I couldn’t wait and had already installed the necessary software on my development [...]
