About us · since 2007
Electronics for calm since 2007
Happy Electronics designs and makes electronics for sleep, relaxation and biofeedback, and builds its own app for every device. Since 2015 we have partnered with Urbandroid, and our devices are official Sleep as Android accessories.
Happy Electronics s.r.o. was founded in 2007, but we started with devices for relaxation with light and sound — so-called mind machines — even before the company existed. Since then we have designed our own hardware, written firmware and developed apps.
Today we stand on three pillars: sleep (Sleep Phaser, Noxuma Sleep and accessories for Sleep as Android), light and sound (Sleep Mask V2 and Brain Control) and stress and biofeedback (oximeters, Emet Wireless and StressLocator Pro). Our main apps also work without our hardware — the device is an extension, not an entry ticket.
What sets us apart
Three things we stand on
Everything under one roof
Electronics, firmware and apps for iPhone and Android are made by us. A supplier makes our circuit boards; assembly and programming happen in Prague.
Partnership with Urbandroid
Since 2015 we have worked with the Sleep as Android team. It is the most important relationship of the whole company.
Privacy and fairness
Noxuma Sleep is free, with no account and no ads. Your data stays on your phone.
Partnership
With the Urbandroid team since 2015
The collaboration began in 2015 with the Mindroid Glasses light glasses and the first sleep mask for Sleep as Android. In 2017 we launched the Sleep Phaser lamp together — more than 800 people backed the Indiegogo campaign.
We developed Sleep Phaser together with the Urbandroid team (Sleep as Android). Happy Electronics makes it in Prague. The collaboration continues to this day.
Our Noxuma Sleep app does not replace Sleep as Android. It brings our lamp to iPhone and offers a simple app for people who do not want to set anything up.
History
Five chapters
- before 2007
Mind machines
We started with mind machines — devices that work with light and sound — even before the company was founded.
- 2007–2013
The company is founded and builds its own devices
Happy Electronics s.r.o. was founded on 16 April 2007. Then came our own light-and-sound glasses Victory (presented in 2007 at Czech Day in Brussels), the PC Mind Machine and Flex USB interfaces for the computer, Victory V2 (2011), our first skin conductance sensor (2010) and the AVS Studio and GsrStudio software. Until 2016 we also sold devices from other makers through the relaxuj.com e-shop.
- 2014–2016
Stress and HRV on the phone
The StressLocator app for iPhone and Android (2014) with Bluetooth oximeters, an ear pulse sensor and Emet — a skin conductance sensor for Android (2015).
- 2015–today
Sleep with the Urbandroid team
Mindroid Glasses and Sleep Mask (2015), Sleep Phaser on Indiegogo (2017), Sleep Phaser V2 (2019), Bluetooth Sleep Mask and Victory Bluetooth (2020), Sleep Phaser V3 and the Shopify e-shop (2023), Sleep Mask V2 (2024), the BM2000D oximeter for Sleep as Android (2025).
- 2026–today
Noxuma
The Noxuma Sleep app (June 2026) brings our devices to iPhone and to new users — alongside Urbandroid, not instead of it. Plus the Sleep Phaser Noxuma edition, the sleep guide, the 3D assembly guide and Emet Wireless (pre-order since September 2026).
