Sound Effects / Running TDA7052 from speaker outputs
« on: March 04, 2013, 04:26:28 AM »
So I'm looking to boost the audio output power of a couple of FragTag boards that I have. I though of using an external amplifier circuit based on the TDA7052, pretty much exactly like what is on a MilesTag CORE board. The only issue is that the audio output from the ISD2560 on the FragTag board is via the speaker outputs. If I run the +speaker output from the ISD2560 into a TDA7052 is that going to work ok, or is it a terrible idea that is doomed to failure?

LEDs, Optics and Sensors / LED wattage
« on: January 24, 2012, 05:41:46 AM »
Someone school me on LED wattage- specifically voltage vs current. With a standard CORE board putting 7.2V through the LED via a 3.3 ohm resistor the LED is getting about 2.18A (by my calculations, correct me if I'm wrong). This equates to 15W.
So if I were to use a 4.8V supply and a 1R5 resistor (which gives the same wattage) would I get similar performance? Or do LEDs not work like that?

Online Store / Pre-made sensor questions
« on: August 27, 2011, 10:54:52 PM »
Hi Jim, just a couple of question-
1) How many TSOPs do the premade sensors have per dome? Is it the same amount per do e for the 2 dome and 3 dome versions?
2) Is there any chance that HiTech could make the premade sensors using TSOP4856 or 34856s? I've got a club that would be interested in buying about ten sets straight away.

EDIT: What has happened to the 2 dome sensors? Are they going to make a return any time?

Online Store / ISDs and domes
« on: February 23, 2011, 10:54:23 PM »
Hi Jim, two things-
1) Would it be possible to buy pre-recorded ISD1790s through the store?
2) The store no longer stocks IR filter sensor domes. Is this a supply issue or are they no longer going to be stocked at all?
