Adjustable Constant Current DC-DC Converter For Solar LED Applications

The current adjustable DC-DC converterin my last post has come out this month. It takes more time to develop than we expected.

The most charming feature of this module is that users can control the output current with potentiometer on board. Current can be set at any number between 750mA ~ 3A, power 2W ~ 100W. This means that user will have most elastic options in different power/current level designs.

After years of looking at motorbikes, riding some, dreaming about owning or buiding one, I have finally settled on building a cafe racer/tracker style electric motorcycle. I've just bought a 1986 Honda CBX250 rolling frame and am currently investigating all electric components.

My new E-bike

I got my new ZEV 3600 on November 6th from DWG, here is their web site http://www.environmentfriendlystore.com/. I haven't had time to post any thing till now.

I then began to uncreated the the bike. The crate was put together very well. It took me about a hour to uncreated it using a electric screwdriver.
