Hi Bouke Sounds like a genious little hack. How dell does it work? And do you have any pictures og the wiring? :) Hi bouke, any updates? would love to know more about the dimming (can you make a video?) Sorry, I've been away for a while but will post an update with the wiring hopefully this week! Y...

Hi all! I've been working on (well, more like envisioning...) almost the exact same thing! At this point I'm just running some simple tests to see if it's possible using the usitwislave library (what TinyWireS uses) - trying to avoid the Arduino and TinyWireS libraries in order to save space. Inter...

By the way, is that switch not just the on/off switch for the whole screen? Or only for the backlight? Just replied to your PM but also wanted to post an update here for other people who might be wondering the same. I did a test with an Arduino Uno and Potmeter connected to the place where the swit...

interested how you are going to fiddle with the brightness of the screen. Are you going to use a pot to make the brightness variable? That would be awsome.... (is that even possible?) ben benieuwd ;) I use a PWM signal on the brightness LEDs (basically replacing the switch which is on the board wit...

Here is my first Game Boy Zero build log. Disclaimer: This will not be a quick build probably. Currently in the process of waiting for parts to arrive and experimenting with some of the features I want to build into the GBZ. Parts List Pi and Storage: Raspberry Pi Zero W $12.45 (arrived) Samsung 32G...

Found this screen today on Aliexpress, seems to be an updated version of the "Kedei" HDMI screen. Same resolution although this one specifically mentions it is IPS, maybe the other was TN? It also features buttons which can be used to access the screen menu. Currently only 10 dollars, seems almost t...

Forked the repository from Camble which is a great start for the I2C communication between the Pi and ATTiny85. https://github.com/regnerus/Safe-Shutdown-Microcontroller Changed the communication library from TinyWire to Wire since I am testing/developing with an Arduino Uno instead of an ATTiny85. ...

In order to do all this you will probably have to enable use of the 'reset' pin, which does make programming it more difficult but hey an extra pin :) I was just thinking about using the reset pin indeed... In my case I could supply the switch with 5v on one side and 3.3v on the other side, wiring ...

awesome!! that actually solves my issue then!! Awesome! the tiny can actually assess its vIn and measure it to a reasonable accuracy (i think) https://code.google.com/archive/p/tinkerit/wikis/SecretVoltmeter.wiki On the website it mentions the following: "This works on Arduinos with a 328 or 168 on...

wont you need to drop the attiny to 3.3v? i think the pi gpio runs at 3.3v It is possible to use a level converter for the I2C communication, however since the Raspberry Pi is running as "master" and the ATTiny85 is running as "slave" this should not be needed. Reason for this is that the Raspberry...
