I chose to use the diode sequence to distribute the heat load more evenly across the heat sink...the circuit draws almost 400mA when all neopixels are on.beoloverhttps://www.blogger.com/profile/18427149493268653743noreply@blogger.comtag:blogger.com,1999:blog-3593368886863596505.post-8013240004706340232014-12-11T16:56:49.811-05:002014-12-11T16:56:49.811-05:00hello, only a little idea. the 1N400x diodes in se...hello, only a little idea. the 1N400x diodes in series can be replaced by a high power zener ziode.in reverse.<br />if you have 40v and connect the zener diode in serie with the cathod connected at the 40v side you get 40 - Vzener at the anode side.<br />you must choose a high power zener diode because it power dissipation will be Vz * I<br />example 5.1V with 100mA give approx. 500mW<br />Genesis.Anonymousnoreply@blogger.com
