Power cord variations
I'm rescuing a machine (PC). But, the AC power inlet differs from a "standard" modular inlet. I.e., a "standard modular power cord" won't fit. I'm pretty sure it is a 110VAC device -- or autoranging...

Supervisor/reset ICs
Do you use some kind of supervisory/reset IC in all your microprocessor/FPGA projects? I've made small quantities of widgets using AVRs and haven't encountered any reliability problems just using the...

Sound system gizmo
So, this would be better on an AV forum or a repair forum -- if someone wants to direct me to, or crosspost this, to a _viable_ newsgroup, feel free. The stage monitors at church are cutting out....

Hair implants
If you have vitiligo it's a good idea to wear makeup. If you are bald it is a good idea to get a hair implant. Pure gold for the older man looking to pull.
