Pedal-Pi, simple programmable guitar pedal

For several years, [Ray] and [Anna], the team behind ElectroSmash, have been smashing audio electronics and churning out some sweet DIY audio gear. This time around, they’ve built Pedal-Pi — a simple programmable guitar pedal based around the Raspberry-Pi Zero. It is aimed at hackers, programmers and musicians who want to experiment with sounds and learn about digital audio. A lot of effort has gone in to documenting the whole project. Circuit analysis, a detailed BoM, programming, assembly and background information on related topics are all covered on their Forum.

The hardware is split in to three parts. On the …read more

PolaPi-Zero For Surprisingly Good Instant Photos

The ‘Pola’ in the PolaPi is a giveaway for what this Hackaday.io project is. This polaroid-like camera, created by [Muth], is a sort of black and white, blast from the past mixed with modern 3D printing. It is based on a Raspberry-pi Zero with a camera module, a Sharp memory LCD for viewing the image, and a Nano thermal printer to print the actual photo. Throw in some buttons, a battery and a slick 3D printed case and you have your own PolaPi.

Right now it’s already on the second iteration as [Muth]s gave the first prototype to some lucky …read more

Adding IceZero To The Raspberry Pi

[Kevinhub] noticed there were quite a few FPGA hats for the Raspberry Pi. Instead going out and buying one of these boards like a filthy commoner, he decided to spin up his own FPGA Pi accessory. This IceZero FPGA board combines the best features from other FPiGA boards, and does it in a form factor that fits right on top of the minuscule Pi Zero.

If you think slapping a Lattice FPGA onto a Pi has been done before, you’re right. Here’s a hat for the Pi using an iCE5LP4K-SG48, an FPGA with 3520 LUTs. The CAT Board from Xess  …read more

Pikelet – A Pi-Zero PC

There are many uses for an old 10 Mbps Ethernet hub besides using it as a speed-bump in your network. (No fun in that!) [thinkerzone] decided to gut an old EN104 Bay Networks ‘Netgear Hub’ to re-purpose the solid steel case as a Raspberry Pi Zero PC housing. The project, which [thinkerzone] called Pikelet, aims to be an ‘IoT server’ with the feel of a PC. Note: a PC, not a Gameboy. In his hackaday.io project, he describes the minimum set of features for the Pikelet.

  • Power button – PCs need a power button
  • Power and Status LEDS – Blue

Pi Keeps Cool at 1.5 GHz

Hackers have a long history of overclocking CPUs ranging from desktop computers to Arduinos. [Jacken] wanted a little more oomph for his Pi Zero-Raspberry Pi-based media center, so he naturally wanted to boost the clock frequency. Like most overclocking though, the biggest limit is how much heat you can dump off the chip.

[Jacken] removed the normal heat sink and built a new one out of inexpensive copper shim, thermal compound, and super glue. The result isn’t very pretty, but it does let him run the Zero Pi at 1.5 GHz reliably. The heat sink is very low profile …read more

Pi Zero Transforms to Game Boy

[GreatScott] bought a Game Boy case. Normally, you’d assume you wanted this to repair a damaged Game Boy, but in this case [GreatScott] used a Pi Zero and some 3D printing to build a game system into the tiny box. You can see some videos, below.

Two interesting parts of the project are the source of the LCD display (a rearview camera screen) and the selection of batteries. Lithium ion batteries are all the rage. But if you watch the news, you know there are some safety issues with using the batteries, especially if you use them improperly. [GreatScott] decided …read more
