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 wish you Merry Christmass and A Happy New Year. I hope Santa will bring you all that you’ve wished for and may the new year make all of your wishes come true. I will post new projects next year, and the Spectrum Analyzer is almost ready. See ya`
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.
Today my order of samples from Texas Instruments arrived. Nicely packed in antistatic bags, i got the following parts:
TAS5414A – 4-Channel Automotive Digital Amplifiers
AMC6821 – Temperature Monitoring and Fan Control
TPA6120A2 – High Fidelity Stereo Headphone Amplifier
PGA4311 – 4-Channel, +/-5V Audio Volume Control
TMP100 – Digital Temperature Sensor with I2C Serial Interface
TI, was very nice trough the delivery steps, they even gave me a call and told me that if i need support in finishing up the project i should send an email to their support and they will happily answer my questions.
I’m planing on building a nice amp with that TAS5414A, I’ll post details here, later when I’ll get started working on the amp.
The movie shows v1.1 of the firmwire in action. Tomorow I’ll be ordering the pcbs and parts.. The final version will use bargraph LED’s for the display and it will be composed from 2 boards, the motherbord containing most of the parts and the LED board containing only the bargraphs.
