My lifetime project: building an 8-bit computer using Z80 CPU. This week I had a bad flu and could not do anything useful so I decided to dig up my old plans for this project. I first re-designed many things, like power, CPU-board, IO-board and so on (my old plans were around 10 to 15 years old). After some thought I realized: When I get even the CPU-board working, I want to display some stuff! So why not build the display adapter first. Plus I planned to build the adapter in a way that it can be used separately from the computer itself. Easy thing to start with.

Its lifetime may not be quite over yet, but the humble television is facing some stiff competition from the computer, as the entertainment portal of choice. Widespread access to superfast broadband means that users are now able to stream films and television shows, download music and of course browse the net 24/7, from wherever they are in the home.
Around 94% of homes in America are now online, and the television is starting to lose its dominance as the most watched screen in the house.
Smart televisions may be the way forward for those looking for easy access to online services, but for many people the computer is the only, all-purpose entertainment device needed. Television networks have recognised that we are now becoming an online society, which is one of the reasons why so many shows are now also available via the net.
Print newspapers are in decline due to the implementation of online versions and of course, it’s becoming almost impossible to find those film rental stores thanks to film streaming! Desktop computers and even laptops are quickly becoming the only device you need for every form of home entertainment. Read the rest of this entry »

Mix real and digital game worlds, play video games outside and create your own Hybrid Games!
Hybrid Play is a device for you and your children to experience and create new virtual adventures, and play them in playgrounds and parks. Play video games outside using the playground as a control interface. Hybrid Play promotes outdoor physical activity, verbal communication, and teamwork. Help us shape a new way to play!
Hybrid Play was designed for kids aged 6-12, and for parents who want to create with technology. It’s a fun, stimulating way to create and discover incredible video games, play outdoor, make exercise and communicate with other people.

A lot of people have been (usually unfavorably) comparing the Edison to single board computers like the Raspberry Pi. Let’s do a little A:B comparison, shall we?

This compact Fremont subsystem reference design accurately measures low voltage, 0 to 100mV, single-ended analog signals with a high-accuracy, 16-bit analog front end (AFE) complete with an isolated data path. The design optimizes the functions of an ultra-precision low-noise buffer (MAX9632); a highly accurate ADC(MAX11100); an ultra-high-precision 4.096V voltage reference (MAX6126); a 600VRMS monolithic data isolator (MAX14850); and low-dropout (LDO) regulators providing regulated +6V, +5V, and -5V power rails (MAX1659 and MAX1735).This one-of-a-kind AFE solution works in many applications requiring low-voltage input, high impedance, and high-accuracy analog-to-digital conversion.

We know you guys like to eat during night (the best time for programming and hacking) but this is a really unhealthy habit and we want you fit and healthy.
The alarm for your fridge activates at a certain time and sends an email (to your girlfriend, mum, enemy or whoever kicks your ass) every time you open the door of the fridge.

It is often said that “the devil is in the details.” All too often those details are hidden deep within a datasheet where you can easily overlook them. When a datasheet reference circuit is copied into a product, the designer must still be fully aware of how the circuit functions and anticipate unexpected problems that might arise from slight deviations.
Take a recent case of an LT1640 hot-swap controller IC, often used in a hot-plug telecom fan tray. I was asked to reverse-engineer this so our technicians would know how to power it on the bench without a using a chassis. Nothing complicated about it, just the usual slow turn-on of a pass MOSFET in series with the load, thereby slowing the dV/dt and limiting the inrush current to the load input-filter capacitors.

The old resistor decade boxes consisted of a bunch of rotary switches which make them little bulky and expensive. Stynus has built this microcontroller-based resistor decade box that uses one rotary encoder and 16 relay switches to switch on the various resistances. The microcontroller used in this project is PIC16F84A.

What if your dryer could send a notification that would buzz your phone or smartwatch to let you know your laundry is done? Well, it may be easier to tap into the brains of your appliances than you might think, with the US$20 open-source Green Bean module announced today by GE at MakerCon in New York.
