Wave Bubble 2010

The operation of transmitters designed to jam or block wireless communications is a violation of the Communications Act of 1934, as amended ("Act"). See 47 U.S.C. Sections 301, 302a, 333. The Act prohibits any person from willfully or maliciously interfering with the radio communications of any station licensed or authorized under the Act or operated by the U.S. government. 47 U.S.C. Section 333. The manufacture, importation, sale or offer for sale, including advertising, of devices designed to block or jam wireless transmissions is prohibited. 47 U.S.C. Section 302a(b). Parties in violation of these provisions may be subject to the penalties set out in 47 U.S.C. Sections 501-510.

Another idea just to throw out there, if the microcontoller is to be upgraded i think it would be a great idea to replace the antenna board with an LCD / Switch board. Even just adding some sort of header that would allow for future add-ons would be quite beneficial in the long run.

Wouldn't it be possible to significantly improve upon the original WB by adding an amplifier/repeater in series with the unit? I know these are often big, expensive etc., but just curious.

I've started to put together a wiki page for this version of the project. Feel free to make changes and additions.

Ordered rest of the missing parts from Digikey for my Wave Bubble design.
When they arrive I will do a final PCB design check prior to manufacturing.

Then we will see if it works or not... :wink:

One thing I'm adding to my design is a MCP73843-410 Li-Poly charger and a 3.7V 6Ah li-poly battery.

More information on:
MCP : http://www.microchip.com/wwwproducts/De ... e=en010554
Battery: http://www.sparkfun.com/commerce/produc ... ts_id=8484

Vin in my case will be a USB Universal Charger Solution wall adaptor. That means D+ & D- are shorted together (< 200Ohms) and Vusb is 5V at upto 1800mA.

Any further news?

Looking at Digikey, it appears a number of parts from the original design have gone out of production. The LiPo charger chip in particular doesn't appear to have a pin-compatible replacement.

Made some progress on my Wave Bubble 2010.
Schematic and layout are all done. All components delivered. Waiting for a new set of main PCB's due to problems during production.

See first post of thread.

Did you by chance order black pcb? They look great compared to the greens and standard color..

When yours is finally up and running , of course, planning to get a bulk order through?

The manufacuterer which I use is more focused on quality with low costs rather than fancy features, so there will be no black PCBs.
But I will make the layout data available for download, so you can have your own PCB, even in black.

A bulk order is possible, but like you said, not before anything is successful up and running.

When I get confirmation that this new version works correctly, I'm willing to do a bulk order of black PCBs. Of course, I want there to be some sort of proof of interest before I go and order 40 sets. I don't want to have 35 sets sitting on my desk for 6 months.

Got my new main PCBs today. This time they are correct.
So I can continue with my Wave Bubble.

Since I have access to resonable equipment I will perform some measurments regarding frequency range, output power etc.

Results will be posted here.

Started with populating the main PCB and finished up the power supply section.

All output voltages are present and correct. We ave 3.3V, 5V, 12V and 22V down to a battery voltage of 2V!

ON/OFF switching with tactile switch via FET works nice...as long as no AVR is connected :-/
With AVR the circuit gets partly powered through the AVR and will drain the battery.
Circuit and PCB design is already changed for further versions, but my actual hardware needs a quick and dirty fix.

Apart from the design flaw with the power switch all other tests are promising. I already wrote a test firmware to perform different hardware tests step by step.
The RF stage is not assembled up to now, but tuning of VCOs works in full voltage span, also the overlay from the sawtooth generator works with 120Hz and 20KHz. Power switching for both VCOs and gain stages works too.

Here are some measurement results of my actual hardware.
Measurements were performed without gain stage, so all output levels are from VCOs.
