Re: [M100] USB "juice pack"

I just tested the power requirements of my 102. With the battery connectors connected to a bench supply at 5 volts, it draws a very consistent 65mA. I was expecting the current to vary slightly with CPU or screen activity but it does not. I'm so used to CPU idle states which, of course, the 8085

Re: [M100] USB "juice pack"

You know I guess I never said why I was interested in the juice packs relative to M100. Basically it is to power a Pi as a storage device and internet bridge yet still be mobile. But then I thought, since we have the extra weight anyway, what if the M100 could be powered from the same juicepack.

Re: [M100] USB "juice pack"

The pi requires a huge amount of juice relative to the tandy. A stripped down pi will need 500 - 700 mA. The tandy I think needs less than 100. On Dec 3, 2015 4:18 PM, "John R. Hogerhuis" wrote: > > > On Thursday, December 3, 2015, Mike Stein wrote: > >>

Thanks! Actually Steven I think this is the same seller as I saw on Amazon UK. It seems in the US he just advertises the cables for specific devices instead of by specification. I'll write to the seller and see if the exact 6v negative polarity 5.5mm/2.1mm cable can be purchased. -- John.

You could make a short adapter to plug into the Model-T that reverses the polarity of the connector. My question is,"Is the output adequate?" Sent from Outlook Mobile On Fri, Nov 27, 2015 at 1:20 PM -0800, "John R. Hogerhuis" >

Re: [M100] USB "juice pack"

John, I was looking at the Pi Zero and figuring that having that and an FTDI adapter would get you something you could possibly run your tools on and have a full TPDD plus other tools in a small space that would be a "bump" on the end of a m102 or m100 (or 200 in my case). I'm probably going to

Re: [M100] USB "juice pack"

Yes, it's definitely worth re-iterating that Model 100 connector polarity is the opposite of most all power supplies you could buy off the shelf these days. The outside is positive, the inside negative. Having applied a pack with a cable the wrong way round (guessing rather than reading the

Re: [M100] USB "juice pack"

Looking at the Technical Reference Manual, there is a reverse-polarity diode in series with the negative (center pin) of the jack. This provides basic reverse-polarity protection but will also cause a small voltage drop (typically 0.6-0.7 volts) between the DC input and the main power bus. If you
