Update: New IR component kit perks & 80+ backers

August 15, 2013AnalysIR Blog, Crowdfunding & BackersArduino, backer, export, GUI, Import, Infrared, IR component kit perk, IR learner, IR receiver, modulation frequency, User InterfaceUser Two

Today we have added a new perk of IR starter kits and retired some of the other perks.

The kits are provided as a quick starter aid for backers who dont have IR receivers to hand. Please note that a learner IR receiver is required to measure the modulation frequency and at least one IR receiver is required otherwise (=Kit A).

Of course you can still use the powerful import/export feature without any Arduino or IR receiver connected.

Please feel free to purchase your own components directly. Otherwise we have a student ready to do all the leg work for a small bribe (oops I meant Tip).

On the technical side of things – we have greatly improved the performance, design & implementation of the Arduino based code along with some User Interface improvements, over the last few days .

Finally, a big welcome to our latest backers and thanks again to all our 80+ backers.

Update: AnalysIR Auto-clean feature for IR signals

Here is a screenshot showing the new automatic signal cleaning feature in AnalysIR. You will notice in channel 2 (yellow & red) where I have overlaid the recorded signal from CH1 (green) on top of the cleaned signal in CH2 (yellow). The green & red signal is the recorded signal & the yellow signal is the ‘cleaned’ signal.

The reason for the signal degradation in the first place is due to the way all IR receivers work. Typically, marks will be shorter and spaces will be longer. Also, weak IR signals will also alter the duration of marks/spaces.

Combined with AnalysIR’s sensitivity setting for decoding it is possible to rebuild a perfect signal from a really poor signal.

With this new ‘Bonus Feature’, we can export almost perfect signals from AnalysIR and re-import the exported signal to compare against the original recorded signal. This will be a great benefit when designing IR devices or circuits.

20+ IR sensors evaluated & Arduino first for AnalysIR

We got 11 different IR sensors delivered by UPS today for testing & evaluation. So far we have established that the sensors we were already using are probably the best. At this stage we have evaluated over 20 different sensors & will probably leave it atthat for now.

We also managed to measure the modulation frequency and the ‘demodulated’ IR signal simulataneously on an Arduino (Duemilenova). This was achieved with the Arduino plus 2 cheap components (More later). No reason it wont work on other Arduino models running @ 16Mhz

This should allow us to report & record the Decoded IR signal along with its modulation frequency for every signal decoded by AnlaysIR.

We have essentially cracked the Arduino bit, but the Windows GUI will need to be updated (hopefully during the campaign).

From a technical perspective, this may be a first on the Arduino (At least i havent seen it implemented simultaneously before).
