• LCD 7 inch with HDMI input and touch panel needs only 5V to operate

  The resolution is 800×480 pixels but the driver will auto scale any resolution up to 1080p.

• Upgrading my Chumby 8 kernel part 7: touchscreen

  I have a lot of experience dealing with touchscreens, but it has typically been with USB touchscreens that come with an off-the-shelf touch controller already supported by Linux, such as EETI’s eGalax. You typically just have to make sure you have the correct driver enabled in your kernel config and then it works. Of course, you have to deal with calibrating the touchscreen as well. More on that later.

• New Project: Juggling Robot

  I’ve been looking for a new motor control project to tackle that is both interesting, and a bit more unique than another Ascento clone. Looking around, I was surprised at the current paucity of robots capable of more advanced juggling feats. There are quite a few that can manage 3 balls, and nearly none I’ve found that can manage more, with the exception of Nathan Peterson’s inclined ball roller. I figure that I have access to lots of factory second moteus controllers, which are capable of quite demanding control applications, so I should be able to put something together.

  This is what I’ve got so far: [...]

• The Raspberry Pi Store comes to Leeds for the festive season

  We have every single Raspberry Pi computer and microcontroller in stock. Yes, including the newly released Raspberry Pi 5. We also have stock of Compute Module 4, which is usually only available from a limited number of Approved Resellers. All the peripherals you might need — including keyboards, power supplies, LEDs, and breadboards — are for sale too.
