Adafruit launched it’s PiTFT not long ago and I bought one immediately from Pimoroni. Soon after that Adafruit published a tutorial entitled DIY WiFi Raspberry Pi Touchscreen Camera. I had a good read through it and on the final page the final paragraph was;
The package could be slimmed down considerably; there’s a huge amount of empty space between the PiTFT and Raspberry Pi (even more with a Model A board). Advanced makers could squeeze a slim LiPo battery and a 5V boost converter in there, connecting to the expansion header at the right edge of the TFT board instead of the side-protruding USB power connector. The result would be similar in size to some consumer point-and-shoot digital cameras.
Hmmm OK, Challenge Accepted!
But let’s see if we can fit in a charger too, and attach some lenses while we’re at it. Modern cameras feature both as standard, no reason why the SnapPiCam shouldn’t……
PiTFT Mini Kit – 320×240 2.8″ TFT+Touchscreen for Raspberry Pi – Is this not the cutest little display for the Raspberry Pi? It features a 2.8″ display with 320×240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! Read more.
USB LiIon/LiPoly charger – v1.2 – This is a Lithium Ion and Lithium Polymer battery charger based on the MCP73833. It uses a USB mini-B for connection to any computer or ‘USB wall adapter’. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The fast-charge current is 500mA by default, but is easily adjustable from 100mA up to 1000mA by soldering a through-hole resistor on-board. Read more.
Lithium Ion Polymer Battery – 3.7v 1200mAh – Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 1200mAh for a total of about 4.5 Wh. If you need a larger battery, we also have a 2500mAh+ mode. Read more.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
