Re: [Mp3elf-users] Help! elf not working

Hi Yann.

Thanks for the suggestions. With the help from you, Chris and Alastair my=

elf works great!

I'm very fortunate living here in California, our (100 year old) house ha=

a full basement, and several years ago I pulled CAT5 into every room, rew=

all of the telphones and the home LAN via a punch blocks in the basement,=

with wall plates throughout the house. A couple a hubs, a router and a LR=

firewall later and the LAN has been in good shape for a while. Networking=

What kind of problems did you have?

Good suggestion - I was lazy and just reflashed *everything* and set the
TINI for DHCP.

My setup is using slush. Have you tried without slush? The TINI docs indi=

that running user programs was much faster. If you tired a "slushless" se=
tup,
how well did it work?

I took the uncased elf down to the nearest RadioShack store and asked abo=

power supplies. RadioShack has a huge selection, and all the power suppli=

use modular tips. In the end I played it safe and and got a 7.5V supply.


Thanks again for the suggestions.

For anyone who's interested, here's what I figured out about the power su=
pply:
The spec is listed on the features page, and the discussion list has some=

instructions on how to wire for 5V DC. On my elf the connection pairs for=

R7 and R8 are wired, which means the power supply should be 7 to 12V AC/D=
C
unregulated, center tip positive, and at least 300mA without an LCD. My
elf has a 4x20 LCD, which I guess uses around 100mA (anyone actually know=
?),
so I got a 7.5V 500mA ps and it works fine.
