It is unsupported because it is ILLEGAL in every UN member. Ladyada makes that very clear. However there is ample "support" for this project in this forum.

switches to giuseppe64

by losthorizonmba on Tue Aug 28, 2012 5:32 pm

There are two switches (S1, S2) in the WB 2010 schematics, gerb files, BOM, as well as the PCBs

thanks for answer so what the s1 and s2 used for? and what is the best scheme in eagle format? can i use the wave bubble for 900mhz and 1900 mhz in the same time?

Hi!

I'm working on this project too and I would like to do the two versions of this project: with external antennas and with internal antennas(PCB). So, I'm seraching the radius and the lenght of the PCB antennas to calculate their power (emission power). I have already the Schematic files and the Eagle diagrammes, but I'm not able to take the next step. Someone, knows this information already or can show me a link where I can find the information?

Thank you a lot, :)

Hello:
I'm doing a school project and I wish I could help calculate the emission power (in watts) of this jammer, I am now looking for that sort of data, but the only thing I'm missing is that.

I'm having trouble communicating with the Atmega168. When I open my programmer it says that it cannot enter programming mode. The voltage read is right, and the lines to the chip are all correct without any shorts or unintended openings. Also, the chip is getting the proper voltage and current it needs. The programmer says that it was expecting a certain value to be returned but instead it got 0x000000 (or something close to that). Any ideas? Also, what kind of total current draw should I be expecting for this version (2010) of the Wave Bubble?


Program: Atmel Studios
Programmer: AVR Dragon (via ISP)
Set Clock Speed: 1 MHz

At the risk of keeping this thread alive I will offer suggestions. Starting a new post will probably work just as well and keep posts on topic if my suggestions do not work.

0x000000 means it is not communicating with the chip at all. I had this problem before with another project and eventually found out it was my own fault.

Make sure you are/have burned the correct fuses to the chip. Double check that you have the clock fuse set correctly. Make sure you have the communication speed of the programmer set correctly.

I had the "Divide by Eight" fuse set which meant my uC was running much much slower than the programmer expected.

tl;dr
Things to check:
Correct fuses burned to chip.
Correct communication speed set by programmer.
Correct device signature based on chip (i.e. atmega168 is not the same as atmega168PA).

I think it may be time to make a 2013 version, using an ATMega32u4 with the Arduino bootloader. That should remove some of the programming hassle.

would be great to have it with an LCD too :)

Why does that ALWAYS come up? Why do you need an LCD? If it's to add a PC-less way of adding bands to inhibit then I think it's out of scope for a basic cig packed sized jammer. Obviously if you want one please design it yourself, but I just cannot justify the wasted power, programming and board space to myself.

though there are really "green" LCDs for some time now, I guess a simple LED needs more power ...

it would make things a bit more comfortable and I don't see any wasted space either :o

and, on a side note: there are people who don't know how to simply implement it themselves
there must be a reason why "this always comes up", else it wouldn't ...

Both RC1, RC1a and 2010 are pretty much jam packed. To accommodate an LCD screen extra stuff has to be put on like a larger microcontroller or port expanders. You will also take a hit to battery life on something that gobbles power already.

There's also an argument for plausible deniability. A PCB with antennas could be passed off as a "magic healing waves" where as a screen saying "inhibiting 300MHz to 500MHz" would not be looked kindly upon.

Meh, if ever do a redesign I'll see about adding an I2C header for a I2C Human Machine Interface (HMI) board.

yeah, well I was thinking about an I2C LCD, IIRC there were some kind of cell phone LCDs that could be used
or normal LCDs with some HC165 IC attached, but that's just details

you're just thinking about camouflaging the device? I mean, here you could run around with it and nobody cares what you carry around
there's no police perfoming bag searches or anything like that, so IMO appearance isn't a problem for most people who might build one of these jammers :)
for me it would be comfortable to (for example) see something like battery level, frequency band, transmitter on/off or something like that :)

Solved the initial problem (error: 0x000000 returned signature). Thanks to lightningserpent for the help. The clock speed setting was too high (though the datasheet said it was fine). Changed it and the programming went smooth from there. However, the LM358 directly after the potentiometer has an odd output (both outputs). It isn't a smooth sawtooth wave. Instead, I get a wave that makes its way up to 3 volts (smoothly) then a large jump to the full voltage of the 24 volt line. It seems like the amplifier is doing what it's supposed to do (gain is correct), but the jump up to the max voltage seems a bit odd. Any suggestions?

For future reference:
When using the Atmega168, set the clock speed to 250 kHz.
