"Earlier this year, I attended a conference and was shocked to find that you could actually buy voting machines on eBay. So I bought one, two months ago, and have been able to open it up and look at the chips."
Beatrice Atobatele is trying to hack one of the most commonly used voting machines in the US, to look for security vulnerabilities, but not with any criminal intentions.
Beatrice is actually one of more than 200 people who have signed up to a volunteer group of security experts and hackers called the Election Cyber Surge.
And by understanding how this machine works, she hopes she can ensure any vulnerabilities are fixed.
"I've bypassed the authentication itself," she says.
"I'm still learning and trying to find any new vulnerabilities that might not be known about yet."
The problem with US elections, Beatrice and others say, is how disjointed they are.
Most estimates suggest there are about 8,000 separate election jurisdictions. The equipment and voting methods vary dramatically. And every step of the process is vulnerable to hackers and human error.
