Running at full power (both RF channels on at all times), the draw is 650mA from 3.7V. There are 2 board designs available for download, one with a Li-ion battery (nicer, smaller, more expensive) and one for AAA batteries (more basic, cheaper but less convenient). @ 3.7V the current draw is 650mA, at 5V its 500mA so most small batteries will give you about 1 hr of runtime (unless you go for a lar… text/html 2008-08-19T19:29:08-05:00 http://www.ladyada.net/wiki/wavebubble/errata?rev=1219188548&do=diff Unfortunately, there are many errors or discrepancies between the various resources available for this project. Eventually, they will all be listed here; if you can then update one of the resources (schematic, PCB layout, assembly directions), please do so and then remove the error from this list. text/html 2007-12-07T10:04:15-05:00 http://www.ladyada.net/wiki/wavebubble/make?rev=1197039855&do=diff Small intro will go here... * Preparation * Battery * Power Supply * Tuning System * VCOs * PLL * Configuration * Gain Stage * Finishing Please note that the information in this section of the wiki is currently a WIP and does not yet include the error information found in the errata. text/html 2009-08-17T01:08:16-05:00 http://www.ladyada.net/wiki/wavebubble/partslists?rev=1250485696&do=diff Full List (Work In Progress, Updated 8/16/2009)Qty Description Part Number Notes Name Minimum Qty Unit Price (USD) Price (USD) Unit Price (EUR) Price (EUR)Resistors1RES 1.0M OHM 1/4W 5% 1206 SMD311-1.0MERCT-ND R710$0,08$0,800,06 €0,60 €1RES 120K OHM 1/4W 5% 1206 SMD311-120KERCT-ND R310$0,08$0,800,06 €0,60 €1RES 12K OHM 1/4W 5% 1206 SMD311-12KERCT-ND R410$0,08$0,800,06 €0,60 €2RES 2.0K OHM 1/4W 5% 1206 SMD311-2.0KERCT-ND R2, R510$0,08$0,800,06 €0,60 €1RES 20K OHM 1/4W 5% 1206 SMD311-20KERCT-ND R1… text/html 2009-02-23T10:27:37-05:00 http://www.ladyada.net/wiki/wavebubble/pll?rev=1235402857&do=diff PLL Notes when running the test_pll1 code. the rc1a firmware will set Ftest(pin 10) to 5hz (not 1hz as per the pll docs). text/html 2008-08-16T16:13:40-05:00 http://www.ladyada.net/wiki/wavebubble/power_supply?rev=1218917620&do=diff Power supply notes Due to the various odd voltages required by RF stages, there are no less than 4 rails: * 3.3V for digital/analog wave generation * 5V for RF gain stage * 12V for VCO power * 20-28V for VCO tuning * If you're using the PLL tuning system, there's an additional 2.5V rail (in the PLL section). grr! text/html 2007-12-07T10:12:14-05:00 http://www.ladyada.net/wiki/wavebubble/preparation?rev=1197040334&do=diff Overview Each step of the project has a parts list, assorted assembly photos/videos and testing procedures. The parts list is as complete as possible, with suggested parts and cost. Many parts can be sampled for free or low cost, but this is starting to become harder and harder. Parts may have to be purchased in larger quantities than necessary, and I always suggest getting twice as many parts as you'll need in case something goes wrong. text/html 2007-12-07T08:04:57-05:00 http://www.ladyada.net/wiki/wavebubble/start?rev=1197032697&do=diff Wave Bubble This wiki contains supplemental info for the Wave Bubble project.
