    level N channel mosfet that can take several amps without needing a heat sink In this case it is the IRLR2905 Dimensions 25 25 mm IR raw receiver A little board that receives 38kHz modulated IR radiation which is typically used by remote controls using the TSOP38238 The code on the ATtiny85 does the signal recognition and sends out byte sized commands to whatever is connected using a bit banged serial output Now with a voltage regulator and new header silkscreen No more 12V accidents Tiny LED ring light This little thing was created to assist my old digital camera during macro photography Alternative applications SMD inspection microscopy Relevant blog post This and that Openbench logic sniffer pull up down wing The OLS is a very nice and affordable device There s one issue though floating inputs They show up as random noise or cross talk from other channels This little add on will enable you to add 10k pull up or 10k pull down resistors as you like using easy to use piano style dip switches The pull up voltage is selectable in two banks from 5 0V 3 3V and 2 5V borrowed from the OLS itself with a 4 pin connector Boardsize 50 x 50mm Please don t ask me about propagation delays balanced trace lengths and so on It s just a simple board Currently I m waiting for the boards to arrive from elecfreaks Edit It works Pull up resistance at 2 5V needs to be about 4k at higher voltages 10k seems to work fine Pull down works with 10k just fine so far I have 9 boards left over bare PCB no parts If you want one click here A discussion on the subject in the dangerousprototypes forum And finally the fully assembled version is ready It works satisfactorily up to 100MHz sample rate RLE At 200MHz things still look OK but when using RLE as well only grounding the probes gets rid of the unwanted crap creeping over from other channels Using a lower than 10k pull down resistor network might be a way too The discussion on the forum has taken off lately lots of good information there The next hardware version of the OLS may even come with shielded probe wires Who knows It would also be nice if unused channels could be suppressed in the software Openbench logic sniffer pull down wing Bare essentials pull down only variant of the OLS wing Smaller PCB less parts and therefore cheaper to make If you re only interested in silencing unconnected probes and don t care about pull up resistors this is the thing to use Note the full version can do the same if you only populate half of it The design files are part of the full version Capacitive sensor s A first test with this kind of sensor Ordered at OSHPARK the real thing will be purple Search for Recent Comments robert on YauDL Y et a nother
