Can Static Electricity Generate Votes?

artgeeq writes "A recent local election in Washington, DC resulted in 1500 extra votes for a candidate. The board of elections is now claiming that static electricity caused the malfunction. Is this even remotely possible? If so, couldn't an election be invalidated pretty easily?"

Both the summary and article are FUBAR

You can read the board's report on their site [pdf].

Highlights include the following:

Sequoia was the manufacturer of the machines.

They don't know why the error happened. It could have been static, or many other things. The board "accepts Sequoia's determination,reflected in its response to the board's queries, that multiple possibilities regarding the cause of the tabulation error exist, including: the speed which the Memory Packs were processed leading to some type of transient malfunction in the MPR unit; the Memory Pack not making full contact inside the MPR socket; or some type of electrical or static discharge taking place while inserting,reading or ejecting the cartridges at a rapid speed."

"Random numbers" were added to vote totals. They say nothing about write-in votes, except that their procedure calls for auditing vote tallies by looking for "large write-in vote numbers, more recorded votes than registered voters".

The errors were confined to precinct 141 in ward 2.

They recorded 4759 votes, while their audit found that only 326 were cast.

Re:slot machines are protected from static shocks

I always post this on voting machine articles but here goes. . . Take a look at 1.020 in the attached nevada gaming regulations: http://gaming.nv.gov/documents/pdf/techstds_05nov17_adopted.pdf Slot machines are required to withstand 20,000V static shocks at 1 second intervals with no problems whatsoever. They are also required to withstand 27,000 volt static zaps which can cause them to freeze momentarily but must cause no loss of any stored data.

In contrast, when I worked on DDR SDRAM clock buffer chips for PC's, I believe the ESD test was something like 1500 volts.

In short, if voting machines cannot meet the Nevada gaming commission regulations then politicians are at best gambling with our votes.

Does that make then susceptible to "clickers"?

[Mr_Tulip]

In my mis-spent youth, I was able to get free credits from certain arcade machines by holding the exposed part of a lighter (the piezo-ignition type) against the coin slot, and pressing button to set off the electric charge. Every 10 or so 'clicks' would result in a free credit. If these voting machines are susceptible to static electricity, using a clicker on it would likely cause some sort of mischief as well. Oh well, back to the old lead pencil and paper voting, I say :)

Here's the standard they should meet.

The Nevada Gaming Commission has been there and done that. Here are their standards for immunity to static electricity for slot machines. Every slot machine in Nevada meets these standards. (Yes, they test.)

1.020 Electrical interference immunity.

1. A conventional gaming device or client must exhibit total immunity to human body electrostatic discharges on all player-exposed areas. For purposes of this standard, a human body discharge is considered to be an electrical potential of not greater than 20,000 volts DC discharged through a network with a series resistance of 150 to 1500 ohms shunted by a capacitance of 100 to 150 picofarads. The device must withstand this discharge repeated at one second intervals. The power source for this human body equivalent is a high-impedance source such that, in effect, the energy available for a given discharge is limited to that contained in the shunt capacitor.
2. A gaming device may exhibit temporary disruption when subjected to electrostatic discharges of 20,000 to 27,000 volts DC through a network with a series resistance of 150 to 1500 ohms shunted by a capacitance of 100 to 150 picofarads, but must exhibit a capacity to recover and complete an interrupted play without loss or corruption of any stored or displayed information and without component failure.
3. Gaming device power supply filtering must be sufficient to prevent disruption of the device by repeated switching on and off of the AC power. The device must not exhibit disruption when a 1 microfarad capacitor, charged to plus or minus 680 volts DC is discharged between the hot and neutral AC supply lines, at any phase from zero to 360 degrees, with a repetition rate of 30 times per second.

In other words, short of firing a Taser at the thing, you can't interfere with a slot machine with static electricity. (And if you did fire a Taser at the thing, alarms would go off.)
