Note: New service.
I may be able to provide some custom CNC service, depending on the size and if I have the time available. I can easily make custom torque arms and brackets. I can cut steel but wish to avoid any stainless unless they are the easily machinable ones. Composite work as well but this can get costly. You may need to supply the materials since I don't care to stock or order them. PM me about a quote or email me at kinf@embeddedtronics.com

Left-over ebike stuff I have for sale.
Dewalt BMS from 36 volt packs $15
2 Dewalt DC9000 36 volt battery chargers $85 each
The fiberglass battery shell covers left over from the BMC build $20

It's getting harder to keep track of all the many good threads I'm interested in and also to keep the threads I started current. This is my place holder for my projects and what I find interesting on ES.

My first ebike and what it has evolved into.
Originally a DiamondBack, Cyclone 650watts and Dewalt A123 packs it's now a GT Polamar after the frame broke from repeated jumps.
It's used mostly for errands and getting groceries, I have a side bag I can mount for this. I also use it for the trails if my main bike is in service and this frame won't break, Chromoly.

My second ebike built specifically for trail riding. I have a blast with this ebike every time I'm out trail riding and look forward to the next ride. It's been ultra reliable, just flats to deal with now.
Motobecane DS Fantom, BMC 600W V2 torque and Konion build. The main pack is 8P 10S setup for a 12ahr in the triangle. Another equivalent pack in the rear rack making a total of 24ahrs. click on pics to enlarge.

Since the ES server crash, I noticed most of the pics are now lost and many of the threads I had started were missing pics. I had hoped that they would get them back online. It's been a while now and I fear they are actually lost. This is a bummer since there were some great pics from other builds. I have tried to go through my own archives to repost the pics on my threads. I hope many others can do the same. If there is a pic on one of my threads you want reposted, pm me.
