The mystery of why the power adapters output doesn’t matter is solved. The power adapters we are using are regulated which means that within the 0-2 amp range of load current. Higher load currents will cause the regulators protection mechanism to break the circuit before it does damage. This is not explicitly written on the adapter label but can be seen in the chart of the data sheet(http://resources.mini-box.com/online/PWR-ACDC-12V-2A/specs.pdf). This can also be proven with the voltage tester. An unregulated power supply would output a higher voltage with no load current(circuit) attached. These power adapters always output 12V no matter what the load current is.
Looking at the datasheets for all the components, the maximum load current would be about .5 amps. This is 1/4 of what the power adapter allows. We can actually power a whole hand(2.5) boards with one power adapter.
The adapters are common and used for many D-Link products. For consistency we should get the same model if we need more. We should have enough for now. The model number is AG2412-B.
mysql dump files missing again…. runs fine on command line. capturing output of cron job.
adjusted the script a bit, check again tomorrow.
Assisted Christine with Maven and Flex projects
went thru AccountManagers, EdgeUtils2, and IngestMananger
old projects use flexmojos-maven-plugin 3.2.0, we are using 3.8 now. 3.2.0 is not available at sonatype.org, we just have local server copy at fgmdev.com
old projects have duplicate entries for com.adobe.flex:license:22.214.171.12458 causing MavenAssist to crash
Maven generating different Flex project settings for Mac and Windows?
-locale flag in Compiler settings needs to be empty to compile in Flash Builder/Eclipse? It works fine on Mac, but Windows complains.
added Tooltips to show contractor name and location on Contract Number ComboBoxes, both AddDirectCiteWindow and FundingRequest
mapping Funding Request Data to Financial Status
Submit Date (bf_submit_date) to Submitted To BA/BF
Certified Date (certified_date) to Certified Date
Acceptance Date (acceptance_date) to Acceptance
obligation_deadline_date to Funding must be obligated by
start_period_performance to Period of Performance
Missing Received Contract, Monthly Tech Report, Acceptance Received, MIPR/FAD Requested and Received Dates? dummy for now.
list of questions to ask…
General flow of showing Financial Status
Missing fields from Funding Request, if these are stored in Funding Request, where would you be entering data from? Just the Financial Status or Funding Request or both? If in Funding Request, where would it go?
MIPR/FAD Requested from Service
MIPR/FAD Request Received
Date Acceptance Received
Monthly Tech Report
Which are the editable fields in the financial status data form?
PM Actual Outlay is calculated = obligation – outlay
Remaining to Distribute = gradually subtract amount from total
How are the summary data calculated?
Where would the goals come from?
Reimbursable and Direct Cite mutually exclusive, can we control this like letting users enter data to only one place, not both?
removed all additional fields from budget_amounts table – some fields go into funding_requests table

I could not find the hp solution center software for windows 7. This is needed to set a destination for easy scanning
Still looking for a good chip to control the gain on our amplifier chip
I2C needs to have a 1k resistor connecting each signal to 5v coming from the usb-i2c adapter. This is called a pull-up resistor not sure why its needed. Pull-up is when you connect something to the high side, pull down is when you connect something to the low-side or gnd.
So far I have found big chips with large resistances and tiny chip with good resistance range. I am leaning towards a 14 pin tssop package which will need an adapter(tiny but at least proto advantage sells the adapters). The optimal resistance of the i2c variable potentiometer is 5k ohm which will be in series with another 5k ohm fixed resistor. The reason 5k is the target rating is because the mechanical variable pot we have has a maximum for 1ok. The max volume we want happens around 7680 which is approximately half of the maximum resistance of the variable pot in series with a 5k resistor. Each step in a 7bit(128 step) 5k variable pot is each to about 40 ohm, which means we have roughly 36 steps of control over the volume range we want to use. Most of the chips I am looking at have dual potentiometers which means we will only need 3 to control 5 fingers.
Tried putting a resistor between the + side of the amp output and the speaker to see if anything good would happen due to confusion of how one of the ICs worked. Nope nothing good happened as expected so I must have been misreading tat ones documentation.
