Windows Server’s Certification Authority offers a web interface to request certificates, available at the following URL: https://nomeserver/CertSrv. When I tried to connect to an Enterprise CA installed on a Windows 2008 server, I got this error message: 401 – Unauthorized: Access is denied: Open the IIS management console, select CertSrv virtual directory and click Authentication: Choose Windows Authentication and, on the right,…
Maxim, recently known as Maxim Integrated, published an interesting comparison between the most used serial protocols: Via: DangerousPrototypes
Today I needed to change – using a script – a type A entry in my DNS. Using WMI, you can get MicrosoftDNS_AType class that represents an A record saved in a Microsoft DNS server. The class has a Modify method you can use to change TTL value and IP address of that record. First, you have to get…
Today, I needed to record IMAP sessions on my Microsoft Exchange 2003 server to debug a client. You can enable session logging with the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IMAP4Svc\Parameters Two values control logging behavior: IMAP4 Protocol Log Level ->logging level (0 = disabled, 5 = maximum); IMAP4 Protocol Log Path -> folder logs will be saved in. You…
Tony is working on small expansion boards for the famous Raspberry Pi. You can read about the development of those modules, called MiniPiio, on his blog: [checklist] Protoboard RS232 Full H bridge Relay … [/checklist] Tony wrote also a very good article on Instructables about how to create a breadboard adapter for Raspberry Pi.
In the past, I’ve already wrote about two cheap PCB services: FusionPCB by SeeedsStudio OpenPCB by iTeadStudio On YourITronics you can find an interesting blogpost which compares those two services, including the one offered by OSHPark. PCB quality offered by Seeeds and iTead seems very similar; some users suspect they use the same PCB fabric. The time it takes to realize…
Saturn PCB Design Inc, a US company industry leader in PCB design, released for free a useful utility called PCB Toolkit. The software has many functions, for example: via properties (capacitance, resistance, power dissipation…) calculator; conductor properties calculator; planar inductors inductance calculator; tables with informations about AWG values; … Via: DangerousPrototypes
Succhello mountain (or Söchèl, as it is called in bergamasco dialect) with its 1541m dominates low and medium Serina valley. The path From Aviatico, you can reach its peak following the CAI path number 519; the walk, with an average difficulty, lasts 1h 45m and it’s well indicated: You start from the park at the top of the village…
When I published my first example about using Arduino as a webserver, many of you wrote me asking how to control Arduino using a web browser: in this blog post I’m going to show you how to control a LED from a web page.
If you are sick of ugly beige cases that hide your beautiful projects, Ian from Dangerous Prototypes may have the right solution! 😉 With Sick_of_Beige project, DP with the help of David Moberly reached two goals: [checklist] define standard sizes for its PCBs; design PCB cases that are compatible with those sizes. [/checklist] PCB PCB sizes are defined…
