www.usbfever.com sent me a headlamp along with my bicycle rim USB generator.  So, I picked it up and pushed its power button on the back side, which seems to made of white rubber.  Well, the bad news is that when I went to push the button again, it didn't make any clicking sound.

At that point, I plugged it's USB type A connection into The Robot (my large media center computer) and the headlamp came on.  I dismounted the USB and removed the white rubber cap on the switch and didn't see anything that looked like it was broken.  At this time, I don't have any use for it anyways, all I wanted was the generator.  I don't have any interest in returning the lamp to Hong Kong at this point.  And the generator has not been installed yet.

My bicycle rim driven USB Generator arrived from usbfever.com in Hong Kong via the US Postal Service today, as well as the bicycle GPS mount for my Garmin eTrex 20.  That came from Guangzhou, a city in the Guangdong providene in the People's Republic of China, which also arrived via USPS.  As noted in this log previously, my former chain driven USB generator also came from Hong Kong.

Before the chain generator started to cease, it would only generate power when the chain was in motion. That was enough to prolong my smartphone's battery, but it wasn't always enough to stabilize it's pre-ride level.  Anyways, it only had a 1350mAh generator on it. I also had the cellphone battery and the chain generator connected on a parallel circuit (they were both directly connected to a 4 USB port hub).

In the past, the bike battery would shut off after about 10 minutes in that configuration when supplying power to both the hand GPS and smartphone.  I'm hoping that when I configure them next time to be in a series circuit, that I can generate enough power to feed them both and stay on.  But I'll say this for the new rim generator... it did not come shipped with any installation or operational instructions all.  But I think that will be alright because there's really not much to it.  Just the generator with mounting forks, two holes, two bolts with butterfly nuts and some rubber gaskets.

On new NiMH AA batteries, the eTrex 20 can stay on for 26 - 39 continuous hours without having to recharge.  Unfortunately, the device itself can not recharge the batteries. That must take place in a separate AC to DC wall charger.  And I don't see myself as needing power from the bike battery, or the rim generator unless the field GPS is out of power and I'm out of charged batteries, or the temperature dips down to less than 37°F.

The last time I had this system hooked up on my bicycle, I was using a chain driven USB generator.  But the generator's gear started to make noise and cause some resistance.  I was on the road at the time, so I had to cut it free and throw it in the trash.

At the moment, I'm waiting for a new rim contact driven USB bicycle generator.  Today, I picked up a couple cables at Micro Center in Mayfield Heights of Cuyahoga County.  I was getting help finding them from an associate who was informing me that the generator and battery could cause feedback and burn out one of my hubs USB ports.  That's when I came to the solution that I'll just hook them up in series instead of making the battery a branch off of the hub.

Since the USB bicycle rim generator is on order at the moment, in this picture it is represented by the cookie (in the package).  From the generator, it will go into the external cell phone battery's micro USB port (which is what it would use when charging).  The from the battery, the series will connect to the USB hub (that doesn't require additional power (like from a wall plug for instance).  I used a spare USB conversion bit and some all weather electrical tape to plug the empty port on top.  And from here, power from the generator and battery should feed into the GPS and smartphone.

I have the battery stationed at the top rear corner of my bicycle's frame (under the seat).  Either this or one of my other cables that I have lying around should be able to reach the generator.  But the battery to the hub will require an extension, which at the moment, I believe that I have.  Finally, I'll have to plug the bottom port of the hub considering that I'll no longer be using it for the bike battery.

I found out that the chain generator was only producing about 1300mAH of electricity.  My smartphone is a Samsung Galaxy Note 3 with a 7" screen.  It's power hungry and the battery runs on about 2700mAh.  For anyone reading this, your battery's power output will be printed on it (except for some of you folks using Apple).

Prior to this, I drove to the Medina Section, TP 17B - Abbeyville & Fenn Rd on the Ohio Transit Hiker's Resource's map and guide.  When I was routing this from the computer, knowing the area, I know that the traffic on Fenn can be aggressive and fast.  So, I was driving through at 1830hours and have made the determination to pull the unmarked transit spur and replace its waypoint icon with a warning one.  And rewrite the guide to warn all OTHR transit hikers that they shouldn't use Fenn Rd as a spur.

I've successfully split the power coming out of my chain driven USB genator.  What i did was purchase a 4-way USB splitter that does not require a supplemental power source.  Then I attached two retractable USB cables and plugged the remaining ports with USB cable attachments (like the ones that come with the retractable cable in a kit).

I did that so the ports would be plugged with something inert (doesn't complete an electrical connection). Afterwards, I used all weather electrical tape and I sealed every connection and exposed metal ends.

The employee at Radio Shack in Mentor of Lake County told me today that the store is getting rid of the rest of their un-supplimentally powered USB hubs and that they plan on discontinuing their stocking of this type product. That's because they're not powerful enough to keep peripherals stable when trying to establish a data connection to a desktop or laptop computer. But when all you need is to split power to multiple devices, they'll do fine. I've used one in the car before.

My smartphone is mounted to my handlebars, whereas; my field GPS is mounted with 3 loose zip ties on the top bar of my bike. One of them is looped around the center column.  I use my belt clip where I secure through one of those, then I use a mesh strap with a spring loaded buckle to tie the bottom of the lower portion of the belt clip. The problem is that the USB retracting cable has an attachment that is placed on the end to make it fit into the field GPS's USB port. Unfortunately, it is way too long to fit between the backside of the GPS and the top bar of the bike. Either one of two things will have to happen. Either I'll find an "L" shaped attachment, or I'll have to cut a new field GPS mount from something like wood and mount it to 1" rubber foam pipe insulation using some zip ties that will allow access to the USB port.

I took the bicycle out for a two mile round trip to the convenience store and back.  The truing on the rear wheel and the USB generator worked.  It's like I'm 2 for 2 today and I'm surprised that they didn't give me any trouble. As per how much drag the generator has on the bike, it's hard to say right now and it needs to be tested on a longer route.

So far, it didn't interfere with shifting. With it attached to my Samsung Galaxy Note 3 with a 7.5" screen and having it jammed on, the generator produced enough power to keep the battery at the same level it began with.  However, the smartphone alerted me that it was only getting a slow charge. That usually happens when it's connected to a USB 2.0 port. The Note 3 is a 3.0 phone.  Oh well, sustaining the level is good enough for me.

The new kickstand is a bit tall, but I haven't tested it with a full load in the rear carrier, yet.

I received my USB bicycle generator from Sorcingbay of Lexington, Kentucky this afternoon. But it was delivered between the front screen and main door of my temporary location and I found it with part of the side adhesive about 3/4 undone and the box inside looked like someone might have pryed a corner open? But after I took possession of it, there wasn't a materials or direction sheet. It's pretty simple anyways, so it looks like everything is here. And it came with a warranty card, which I'm pretty pleased about.

Other than that, I woke up this morning and found that it was about 50°F, raining and I still don't have a poncho.  Normally, this can wait, but since I intend to take this bike trip later this month, it might as well get procured now. So, I purchased a medium duty one at Dick's Sporting Goods in person in Mentor of Lake County also this afternoon.
