UPDATE 2021/06/30 : This whole procedure is now super simple if you go the EmuELEC way following this guide:  https://retrogamecorps.com/2020/11/12/guide-pico-8-on-retro-handhelds/#EmuELEC  It's basically just to put the pico-8 in a specific folder, and any roms (unless you just use splore) in another. Last weekend I built the ODROID-GO Advance Black Edition with my daughter. (Apart from re-experiencing my childhood's Commodore 64 an Amiga games,) One of our goals was to run PICO-8 , the great little fantasy console, on it. That seemed possible, given that it shares a similar CPU to the Raspberry PIs – where it runs great. However, it was not that easy to get it up and running. Here’s what worked, but first, what didn’t… Official image First we installed the official image from HardKernel on it. But alas, no luck getting things to run properly. EmuELEC Next up was EmuELEC . There we managed to get PICO-8 to run in all it’s 8-bit glory! But! Controls didn’t work when la...

In my constant... need... to get everything music instrument related to communicate with each other, I wanted to look into ways to get some of my keyboards/synths with only MIDI over USB to talk to devices with regular good old-fashioned 5-pin MIDI ports from the eighties. Cables! First I had a quick look at off the shelf solutions. The most interesting one being the Kenton MIDI USB Host – providing MIDI host functionality for USB devices as well as regular MIDI in and out in a small box. Unfortunately it is rather expensive (~125 €) and a reliable online source warned me that it was not entirely stable in collaboration with my OP-1, so I started thinking of more... home-grown solutions. I decided to try to use my old Raspberry Pi and see if that would serve as a USB host with a borrowed MIDI USB adapter. (Thanks Simon.) A cheaper, and, as an added boon, a nerdier solution. Step 1: Get the USB MIDI device up and running This was the easy part. The device I have been lent ...

A little duo I'm part of these days, 1bisHill (What's with the name you ask? It is a long story...), was asked to play some songs at a gathering at my work the other day. (With a guest star from Brazil.) So, without thinking, I asked my partner in crime, and he said yes, so I said yes. And then I thought about things, and realised that we have lately drifted towards more and more... noise - less, what might be regarded as, ... music ... Perhaps not compatible with playing at people at a party at work. So I got scared. And then I did what I always do when I get scared - tried to find a programmatic solution! This time I created a tiny web service where people could vote for more or less noise. Noisevote, if you want. Pedals with  NSFW names like Big Muff and Swollen Pickle en masse. Basically, server side, it is a really simple Ruby and Sinatra web service with a sqlite database to store votes (running on my Raspberry Pi at home). Client side it is Bootstrap and D3.js w...

Recently I had to liberate some data from an old MS Access DB, so I discovered a gem of a Ruby gem called " sequel " that generalizes database access (for many different databases) - ORM style. Most excellent, so I figured I wanted to run it on my raspberry pi to access various sqlite databases I have lying around. Assuming you already have ruby (1.9) installed, you can simply do (in any Debian flavored Linux, for that matter): sudo apt-get install sqlite3 libsqlite3-dev and sudo gem install sequel sqlite3 So now one can fire up irb and do things like: require 'sequel' db = Sequel.sqlite('some_db.db') Etc . (This will, of course, not let you access MS Access DBs on your pi, as they rely on the "win32ole" gem - only available on windows, and the " Microsoft Access Database Engine " - also only available on windows. More info on how to connect to those kinds of database can be found here  - under 'ado'.)
