usb - Portable Media PC Wifi Signal -

-

I prepared to make myself using Raspberry P & A; An electronics hoop.

With the exception of my wireless signal, the building and testing have been fixed. I have an ADMX USB WiFi dongle, which is hosted in the case of aluminum, and when I close the case, the thick aluminum (Required) blocks the signal completely.

I tried stitching antenna for the wire through the lid screws, but this did not work (sorry, if it was a stupid thing to do, I would like to know more about the antenna design Not even though the wire lid helps in closing and they are not connected).

I realize that I can use external USB port, but I did not want to stop that key, it is very useful to hook up the keyboard or other external devices.

Let me know if anyone has a great solution. I want to be able to keep the lid as close as possible, and to run everything, although in the back panel I have already installed other ports.

Thank you very much,

You walk the antenna in the solar wiring because it will mess with the impedance of the circuit, which is very important for correct antenna function and maximum power transfer. Very few USB WiFi dongles often have a chip antenna that is impossible to modify and extend.

I will get another USB wifi dongle with an external antenna. These are often connected to an SMA connector (or similar), which can be extended from small SMA-F to SMA-M cable and can be purchased from most electronics distributors. This cable can then be brought to a bulkhead connector on your enclosure, which you can connect to the external antenna. You can be lucky and you can get a USB dongle with the U.F.L connector on the ship, which can save some space while walking on the cable wall for an SMA antenna. Keep in mind that many of these antennas are 2.4GHz and can not work with 5GHz 802.11n band.

Pass DB Connection parameters to a Kettle a.k.a PDI table Input step dynamically from Excel -

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
