Thankyou for your feedback Steve! It does appear it gets within .1 Volt's of 5 volts. It appears that it may be suitable for those needing 5 volts for a ACC power on a sensor. Feedback on this is appreciated of course , I have never used 5.1 volts intentionally on a 5 volt sensor ,but it does sound ok to me .

When you put a load on it please pay attention to the temp if the coil and IC. Based on tester feedback I will make the call on the need of a aluminum heatsink. The end product will be heatshrink wrapped in clear and a hologram on the back with serial number.

"hologram on the back with serial number" - what is this, Star Trek?

I got mine today and I'm looking forward to trying it this weekend. Thank you Josh for the sample and letting me test it. Other than heat, is there anything else you'd like us to test? Do you use to post results here on email you directly?

HI Justin , Yes just pay attention to heat , when you test it check the amps your servo was drawing and the voltage you operated it at. Also post the voltage and power source as well please. If I see that the unit sometimes gets toasty then the final version V1 will include a heatsink under the heatshrink and label.

Also about the hologram security label.... yeah dude this is star trek! Haha.

I am doing it for a couple reasons. First being tracking who owns what regulator for warranty and quality control purposes. The stickers are security type with dual strength adhesive that will separate when removed voiding any warranty. Each one will be numbered and those who already received testers will be assigned a number and sticker mailed as well. Here are the manufactoring samples received today , when I get the serial preprinted I will have to order 1980 of them at once (strange number) they are .4" square with fillet corners.

Dang, I've ordered 3 of these from EZB an it takes awhile to get them. (I need them yesterday of course) so I ordered the same they have in stock at Polulu. Your price point is a really good deal. I'll grab a few for sure when you go into production.

Here's the hologram security label proofs

Thanks FXrtst , the idea is to have a fairly quick shipping option , and combined low cost as well. It pains me to see similar products selling for 30 dollars without wire or crimped ends! That hinders bringing easy-to-use tech to the masses.

Agreed!

The first hologram security stickers arrived , test fitted them onto the backs of the switching regulators.

Josh, This is what I have tested so far. I tweaked the adjustment screw more on the inline voltage requlator, and have it holding very steady near 5 volts. I installed the unit on "Ann's" shoulder servo and it operated with no issues. For this test, It is connected to a EZB4 with a LiPo battery. I had the arm straight out from the robot, and held it for 5 minuntes. The unit was definetly warm, but not excessively hot. It was operated at the 5 volt output setting. My meter, set on 10 amp setting, showed 0.31 amps on the digital readout, with the arm extended straight out. I am not sure if it means 3 amps or 0.3 amps. This robot servo is an EZ Robot original kit, not the HD new type. It might be an improvement if it had an insulated cover and possibly a heat sink. From what I have tested, I will probably purchase more units for older servos. I am curious what other testers found?
