stack your knowledge: IOS IPsec ezVPN server – part I
http://staystack.blogspot.com/2013/04/ios-ipsec-ezvpn-server.html
Helpful article, though I wasn’t working with ezVPN. The ‘reverse-route’ component was a critical one I was missing, though I’m pretty sure it’s still not going to get me where I need to go. I’m attempting to get a software VPN client configuration to work with a router that’s also performing IPSec VPN in conjunction with VRF and zone firewall. We’ve already encountered one show-stopping bug between ZBF/ZFW and NAT virtual interface (NVI), and I’m fairly sure about five steps down the road from reverse route injection that we’ve encountered yet another bug that will prove fatal in this endeavor as well.
No matter I guess. Probably need to get this lab back to a more standard configuration in any case. If you do happen to encounter a problem with ZFW, VRF, and software VPN client I’d love to hear about it in the comments. Always nice to know you’re not the only one Cisco’s feature sets are leaving up a creek. If I get time, I’ll try to post a more detailed configuration example and steps that lead me to this conclusion. I still haven’t completely disproven it, and haven’t run any debugs at all yet, so there’s still a slim possibility it could actually function.

Notching, Boring, and Conduit
http://www.familyhandyman.com/walls/drilling-holes-notching-and-boring-holes-in-wood-studs/view-all
I recently subscribed to Family Handyman. There’s an endless supply of useful things to do and build in there. Ran across this page on their site while I was searching for information on drilling and/or notching studs in prebuilt walls. While it didn’t dig into finished walls, the reference for code/recommendations on the allowed size of bores and notches is great.

This reference to sizing for plastic conduit bushings and EMT size is handy in combination with the above. Didn’t realize that neither dimension of EMT actually corresponded to its true size.
I also ran across that link to a list of “Electricians’ Tricks of the Trade” that has some helpful ideas for a lot of handywork and cabling projects.

Mower reference pages
Pages referenced while repairing Sabre lawnmower. Safety switches have been removed and wiring reassembled and functional – can get the tractor to run for a few seconds by spraying carb cleaner in the air intake, but otherwise seems to be starving for fuel. Confirmed that there is power to the fuel solenoid when keyswitch is in the ‘on’ position. Interesting that when I pull the hose from the fuel bowl and then put it back on, it seems like it floods the carb for a few seconds (but I still wasn’t able to get it to start).

Multi-IR remote
This, possibly in combination with this (or at least the software component thereof), might be a simpler solution to something I was thinking about today. I have an XBMC remote control application on my phone and tablets which I like for several reasons. It’s always handy and never lost – or at least easily found – are among the top of these. This got me thinking about running an IP-to-IR remote so I could leave an IR transmitter in some fixed location always pointed at remote controlled electronic devices, and just use my always handy Android to manage channels on all the devices. As an added bonus, the webmote software might provide an option to integrate all the remotes into one single control interface rather than needing different remotes for TV, DVD player, surround sound, and XBMC.
My original thought was just to figure out a way to integrate a USB port on an existing remote control and basically trigger the sending of the commands, but this would probably be more universal and likely much less thought and work intensive.
I found ATmega 88’s here for around $3 each, but haven’t reviewed the full parts list yet.
