    Attempting to identify two sot23-6 SMD Component - LED Driver

    This 1.5V Step-up driver is from a Lumintop AAA flashlight. I will try to change the modes, if I can access the microcontroller... One IC is the Step-up driver, the other a microcontroller. Can anyone identify both sot23-6 IC's? Markings: CFC4w & 0WJ or 0(null)WJ

    Converting lathe - from 380V 3 Phase to 230V 1 Phase

    I read a little bit about VFD EMV & some "noise", who can trip circuit breaker & RCD's from the powersource. --> I don't wan't to blackout the whole apartment block :) I saw in a action board a Danfoss VLT 2815 with a integrated RFI-Filter (class 1a) & brake. The motor cable will be less than 2...

    Converting lathe - from 380V 3 Phase to 230V 1 Phase

    Thanks for the ideas and input's! I have searched some transformers but I couldn't find any 230v-to-460v above 100va in auctions board. Maybe they are here not so common in my country. A 1.5kva VFD in auctions are available for less then 150$. Maybe I search a motor with a higher va rating at...

    Converting lathe - from 380V 3 Phase to 230V 1 Phase

    I have to move my lathe to a new location, but there I have no access to 3 Phase 380V Mains. Only 1 Phase 230V 10A is aviable. Is that possible to wire the existing motor with a Inverter? Which is the right Inverter for the motor? (The capacitor-trick is maybe not the right solution...

    Hi Pablo, Sorry for the late reply, my mailbox was full ;) I will make it für 35.- incl. shipping. About the height for the led: Für the Luxeon 5 its 20mm, I would say emitter + die height = 3mm For a XP-G2 with 1.5mm sinkpad its 1.5 + 0.8 = 2.3mm. So for a XP-G2 the total height would be...

    Opening a KX2 (45lm Single Stage) gone wrong...

    I will use a XR-E Emitter again, I like the good throw. Tried other LED's like XP-E & XM-L: The result is clearly, TIR-optic is made only for the XR-E. A Q5 or R2 with a WG-bin would be nice, like this one: http://dx.com/p/cree-xr-e-r2-wg-emitter-on-premium-star-15943 A PCB who is thinner and...

    Opening a KX2 (45lm Single Stage) gone wrong...

    I cuted a ring from a aluminium pipe who fits on the thread, made a side cut and put in the 3 jaw chuck. Tighten the chuck firmly and put some new rubber and cord on the bezel. ........Success :) The Emitter is completely yellow inside, including the bond-wires, perhaps a P4-Bin. Thanks...

    Opening a KX2 (45lm Single Stage) gone wrong...

    Thanks for the reply, I tried it but it always touched the side of the head and the thread with the pliers :( I tried different strings. Also when heated up to 100°C, the rubber from the bycycle hose slips more one the bezel. --> I should get a real strap wrench. I should do a adapter with a...

    SAFE DIY 18650 1.5A charger, USB powered

    I was never happy with many cheap 18650 charger because I never know if the circuit really stops at 4.2 - 4.25V or a bad power supply with a high impact to the battery. So I bought this "housing": http://dx.com/p/single-18650-17670-lithium-battery-charger-1a-charging-current-5837 For...

    How loud is a lathe?

    I have no experience with wood turning, only in metal. If the the shaft of a small lathe is only driven by belts, its quieter than a cordless screwdriver. With feed activated and an uncooled gearbox (no oil) the noise noticeable louder.
