Re: voltage cutoff for my car radio/battery

I plan to place the circuit in line with the radio only. It won't draw anywhere near 15 amps.<p>It'd be great if you sent me your circuit design.<p>Thanks!

Re: voltage cutoff for my car radio/battery

With some experimentation, I will be able to figure out the minimum voltage required to start the car.<p>The radio is a late model Sony, the battery relatively new, and the alternator is charging it just fine. Can anyone propose a cutoff circuit to get me started?

voltage cutoff for my car radio/battery

I have an old VW that often sits for weeks without being driven. The clock/memory 12V radio feed (yellow wire) seems to be a bit of a hog. When I disconnect it (pull out the fuse), I can start the car after leaving it sitting for a month or two. However, when I leave it connected, I'm lucky if it st...

Re: eliminate static electricity from my burr grinder

Thanks for all the suggestions!<p>In the end, I went low-tech. I'm just adding a teaspoon of water to the bean hopper just prior to starting the grinder. Works great!<p>Still, I would much rather have gone with something Doc-Emmett-Brown-looking that made the wife nervous when I used it. Oh well!

Re: eliminate static electricity from my burr grinder

RonH is on to something. Maybe I should start a new thread entitled "electric starter for my gas grill" or "ignition coil rapid trigger circuit"<p>If a piezo electric device can do it so can lots of windings, right?

Re: eliminate static electricity from my burr grinder

It appears my only options are low tech, huh? Oh well, I guess moisture and grounds straps shall be my allies as I grind coffee.<p>I was really hoping for suggestions on a gizmo to build that would do something like what the Zerostat gun does. Thought it would go better with my propeller hat than wo...

Re: eliminate static electricity from my burr grinder

Found a link where a guy describes using a Zerostat gun to eliminate the static elec. in his burr grinder:<p>burr grinder<p>"Zerostat gun that uses a piezo electric gizmo to generate a neutralizing charge". Can I build such an animal? Will it cost less than the $40 they want for a ZeroStat gun?

Re: eliminate static electricity from my burr grinder

I was kinda hoping for a static sucker circuit of sorts. Something that either pulled the charge off, no matter how little or increased it enough such that a grounding to earth would dissipate it. Don't know a whole bunch about the properties of static electricity, but was looking for something a li...

Re: ICL 9520 POS display

I toyed with a similar unit and remained foiled by the cabling until I finally woke up. I was using a straight thru cable rather than a null-modem cable. Maybe your problem is this simple?<p>If you are sure you have a good connection, the hex strings the unit expects to see are usually pretty simple...

Re: VB and MySQL

Matt,<p>VB6 knows very well how to connect to ODBC sources. Go to the MySql site and download the ODBC driver (it's free), load it per the instructions and use an ADO object to connect.<p>Good luck!

eliminate static electricity from my burr grinder

I have a burr type coffee grinder that is constructed mostly of plastic. For about six months now, it has maintained a static charge that causes grounds to fly everywhere when I attempt to empty the plastic cup the grinder fills as it grinds.<p>I'm hoping there's an eliminator that can be built chea...
