With the Shock Clock, I gave myself a few test zaps when I first received the package. My sleepy brain always says "five more minutes," and I'm instantly back asleep. Even if it wakes me up, I instantly fall back asleep, usually with no memory of being woken up before. No matter what kind of alarm I have, I don't wake up. I've tried super loud alarms, wearable alarms, alarms across the room, alarms that roll away, alarms that require shaking/math/QR codes, phone calls. I've had trouble waking up for most of my life.

We’ve been very interested in the recent projects which are creating custom firmwares for commercially available fitness wearables, as it could be an express route to a hacker-friendly smartwatch. What you’re somewhat less likely to find inside your FitBit however is the LPR6235 coupled inductor and beefy capacitors which are used to build up a high-voltage charge from the standard 3.7 V LiPo battery. There’s a nRF52832 Bluetooth SoC, a MMA8451Q accelerometer, a PCF85063A I2C RTC, and a FXAS21002C gyroscope. Once inside she found mainly the same kind of hardware you’d expect in a standard, non-masochistic, fitness wearable. We can only hope that more devices don’t adopt a similar sense of self-preservation. So until she could get the case open and physically disconnect the battery, all she could do was turn the intensity down in the application and work through the occasional jolts from the device. When tried to take the Pavlok apart, she found that it was nearly impossible to handle it without inadvertently triggering a shock. Check out the video after the break to see it in action. ![]() With the smartphone application, you can control the device remotely with a handy desktop widget that allows you to select the intensity of the shock. But in place of the screen that would show you how many steps you’ve taken or your current heart rate, there’s a lighting bolt button that you can press when you want to shock yourself. We don’t know which of those problems has, but we’re glad to see she decided to take hers apart before the 21st century self-flagellation started.Ĭalled the Pavlok and available for $180 USD from various online retailers, the device looks like a chunky fitness tracker. If you can believe it, the gadget is actually intended to help break bad habits or wake up exceptionally deep sleepers. No, it’s not part of some kind of house arrest program. Apparently, there is a wrist-mounted device that delivers electric shocks to the wearer when it receives the appropriate command over Bluetooth.
