It is actually just used to demonstrate our light pipe recycling technology. I have designed it for a 3D 3.4VDc 35 watt or 4D 4V 50 watt Maglight. It has a wide zoom and uses an aspherical lens in two position. Anyone want a $1,500 flash light :-)

oh my you know your shiat. Thank you so much. I found a dc to dc converter from v-infinity that takes 3 to 3.6 and brings the voltage up to 5vdc 80% efficient so that closes this case. Attached is the going to be a super bright led flash light using light pipe recycling and adjustable...
"First try the fans on 3.3V many would spin and it would save a headache."
"Next was that 13A? What size is this battery? 13A is non-trivial." 4 D cell 11,000mA
The 3.3v fans spin but I need to overpower them to get the correct 15 CFM. 5.5v would be lovely.
13a is The current draw but...
Steven here. Mechanical engineer. I have a pretty nice mechanical design here using a 3.8v dc battery supply and a 3.4v 13A LED. I need to use some 5v fans.
So my question is....
how to get the 3.8v down to 3.6V to 3.3V
and....
how to get the 3.8V up to 5V-6V
There are no electrical...
Hey I have something similar. I have an assembly and I want to do a simple point load test using the free simulation wizard cosmos. It tells me I need to run the simulation wizard to use cosmos yet my assembly is static.
This design is purely for asthetics. As soon as the car starts to move the bearing will rotate along with the rim. Once the car has stopped the rim "lip" will keep spinning. It will have to be some kind of dove tale design (I think). I wish this forum aloud you to post a picture or I...
It will be spinning on the outside of a car rim. So technically " NO load". It would be self lubricating. Also what would be the quitest bearing design.
