The analyzer has become my best travel companion. It’s very discrete: everyone think you are playing with a mobile phone!. You can see in a moment what are the used frecuencies / channels at your location. One of the most interesting things if to carry it in the pocket in exposure mode and walk sometime in your neighborhood. In this way you can find easily what are the free frecuencies or channels. With the time, I learned how to distinguish between different device
This is the final version of the spectrum analyzer, this is the version that will get shipped to buyers. The two boards can be connected either by cable or one on top of each-other trough pin headers. You need to specify the model you want on ordering. You can get the kit assembled or unassembled, for this there are two separate products in the shop(for assembly guide check the forum).
I’ll post some of the most important features and specifications here:
Dimensions:
motherboard: 81×88 mm.
matrix: 236×72 mm.
Power:
7,5 V 1 A DC (the maximum current draw is 600 mA).
power is supplied to the board trough a 2,1 mm DC power connector.
9 display modes selectable trough button 2 present on the display board.
on/off (standby) control selectable trough button 1 present on the display board.
ISP (in system programming, if you have an AVR programmer that supports this feature, you can update the firmwire if new version is released)
First units were shipped, and I’m curious about what you think related to the project so visit the Youritronics forum and share some of your thoughts also if you have any questions you can ask them there.
As you can see there are now 4 displaying modes, and on/off control trough two pushbuttons that sit next to the LED’s. In this version I used a cable to connect the two boards, but the boards can also be connected one on top of each other.
I’ve checked some shipping rates for united states and here is what I got:
Romania to USA, 1 kg:
UPS Express Saver 60 USD 1-5 business days
UPS expedited 62 USD – 2-5 Business Days
DHL – something like 110 USD with 2 days delivery time
Express Mail Service 41 USD probably 10 days
FedEx - 117 USD 2 business days
At the moment it seems that UPS, DHL and FedEx require proforma invoice for the product. Because I’m not a registered company I have no means to provide that so I’ll have to find a way around this problem.
later edit: The solution is Express Mail Service which is the cheapest and I can send the item as a gift thus avoiding any other papers. Delivery time to US usually under 10 days
I received most of the parts for the spectrum analyzer and also the boards, this means i should be ready to ship them to you in a few days, but the holidays are knocking on the door, and i cant work on Christmas eve . Probably the first packages will be shipped on 3-4 January 2009. I hope you’re not upset by all these delays, it’s difficult to maintain a schedule when parts are coming from lots of different countries.
