I wanted to cut off the power totally so I decided to power it from ATmega16 pins directly. The Manufacturers and RS reserve the right to change this Information at any time without notice. In the foto you can see the programmer attatched with it’s pinout.

I’m very satisfied with the result. I solved the problem by not keeping it constantly on like mobile phone screens – they are turned on only when user is using them.

By the way, one more thing: Please select an existing parts list. When the display is on, you have to wait 3 secs and then you can set the time. 24116

Thanks for entering your watch to The Hackaday Prize. One of the requirements is that it be a “connected” device. I always wanted to have a watch but couldn’t afford it. It’s powerded by a coin cell. Below there are contacts to attach a programmer. On the upper side of the PCB there are contacts for buttons to set minutes and hours. Yes, delete it Cancel.

The timer2 is set to overflow and it’s prescaled to Become a member to follow this project and never miss any updates Become a member. The display has one drawback – It uses pretty much current.

Sometimes you can even buy this type of battery from the store when it has less than 3 V left. I wanted to bend it’s top pin but I broke it, so I had to make it from wire. Baby Phone will be designed to look like but be more rugged than a normal phone. I use real time clock ds According to the datasheet – up to mA and it’s a lot for a battery powered device. With Hz clock it overflows every 8 seconds.

And the really cool thing is that I made some swag by myself and I feel proud of it: By the way, I had to extend the gap between it’s pins which need to be soldered to PCB – I’ve cut one and soldered a extending wire.

I have like this one. I wanted to mound display on one side of the PCB and the uc – on the other. Those yellow traces should be connected by using wire. I have short circuited my watch few times accidently when washing my hands or in the rain and protection worked.

When testing the display, I’ve noticed that when it is blanked it still drains about 1mA of current at 5V.

The traces which should not touch are marked by white color. Add to a parts list.
