The Luggage, a Recap
Since EMF 2016 I’ve had the idea for a project I’ve apparently only mentioned in passing on here, The Luggage. Borne of the frustration of lugging camping gear from carpark to campsite, I joked that ideally I’d have something like the “half suitcase, half homicidal maniac” better known as The Luggage, but with less of the mania… Me riding the prototype Luggage Ultimately it’s morphed in to a…
PiWars 2024: The Challenges and Their Challenges
There are seven challenges at the in-person event for PiWars 2024, each with their own problems to solve. They are split in to three categories: Autonomous only, Autonomous/Remote, Remote Only. For the second of those, if you are in the Advanced/Professional category you have to attempt the challenge autonomously. State of the Onion NE-Five exists as a robot, the base hardware is all there and…

NE-Five Upgraded? Yukon Bet On It!
Upgrades galore! Raspberry Pi 5, Pimoroni Yukon, and a banging sound system?! More details in the post linked below!
I’ve been hard at work with a few upgrades on the robot over the past few months and thought I’d share a long overdue update, and if you’re here from the Raspberry Pi blog, welcome! In this post I’ll talk about some of the upgrades to the robot I’ve not covered yet, and will cover each in more detail in future posts. This includes motor control using PID loops, odometry from the encoders, and…

NE-Five Mk4 - It's All About That Base...
The road to PiWars continues! Most important of all is a solid base to build from so that’s where we’re starting. This is the first iteration of the base design, it’s the same width but slightly longer to give more room inside the enclosure. Another big improvement, I hope I least, is that I’ve added suspension to each motor. As this robot uses mecanum wheels it’s incredibly important that all…

NE-Five (Re)design, Lessons Learned
One common questions I get asked about NE-Five is “is it open source” and I always give the answer “mostly…”, there’s a reason for that. The code has been available for a long while, along with a basic simulation that you can run in Gazebo, but the CAD model has never been shared. That’s becuase it’s a mess, to say the least! I hadn’t used Fusion 360 in anger until I started working on MacFeegle…

Making the RedBoard Work on the Raspberry Pi 5
I’ve been using Red Robotics excellent RedBoard for years now, and while upgrading NE-Five to use a Raspberry Pi 5 I discovered breaking changes which means the available libraries wont work. Basically, the way that GPIO works on the Raspberry Pi 5 is different as it uses its shiny new RP1 chip to wrangle its devices. As such, legacy code that used the old way needs updating. In our case that’s…

NE-Five is Going To PiWars!
I’ve been accepted to compete in PiWars 2020! I mean, 2024! As we all know, the theme of Disaster Zone for PiWars 2020 was more than a little prophetic as it was cancelled due to a global pandemic, happily though we’re getting another shot at taking on those zombies as they’re running the Disaster Zone challenges again next year! PiWars 2020 was the first one I’d been accepted in to and for me…

Yamaha Pacifica Upgrade
After refinishing my bass guitar my aged Yamaha Pacifica, recently named Priscilla after someone misread the name on the headstock, was looking a little sorry for itself. I decided to give it some TLC and started looking for new pickups for it to give it a new sound, things then got a little out of control when I discovered the Roland GK-3… Coupled with a guitar synth like the GR-55 it allows the…

Docker, A Reverse Proxy, This Site and LetsEncrypt!
#Docker, A Reverse Proxy, @NeaveEng and #LetsEncrypt!
The site was migrated to SSDNodes last year as my previous host was becoming less reliable and I fancied something more versatile. I’ve not covered it on here but here is how my site runs, now with added HTTPS thanks to LetsEncrypt!
A bit of history. This is a WordPresssite and has been since it was migrated from Windows Live Spaces which shows it’s age! There is an official Docker container…

Bass Guitar Rebuild
#BassGuitar Rebuild
Just after Christmas I bought myself a new bass guitar, an Ibanez GSRM-20B in a walnut finish. It was supposed to have a dark stain that allowed the woods grain to shine through but it didn’t work out that way and was almost black. Now refinished using elbow grease and danish oil, I’m very happy with how it turned out!
 Before and after! It begins… Before taking it apart, I went at…

Hictop 3DP-18: Marlin FW Example Configuration
Hictop #3DPrinter 3DP-18: #MarlinFW Example Configuration
I’ve been quiet on here for a while but anyone how follows me on Facebook will know I’ve not been idle, one of the things I’ve been working on is getting my Hictop 3DP-18 printer running stock Marlin Firmware.
The main reason for doing this is that despite the Open Source basis for the Hictop Prusa i3 the firmware for is isn’t readily available.  Some have had some success getting hold of a copy…

This is a work in progress as it has turned out to be far more complicated than I thought it would be! I’ve learned a lot about how to design parts for my 3d printer and how to use the laser cutter at Reading Hackspace too though so already winning!

To test the cutter, a nameplate!
Left to right, prototype hinges. The final design was the fourth!
My workstation in the staff tent at the Beer Festival
The mess of wires before it was simplified and the old hinges.
Over the passed few years my friends in the Reading Beer Festival Games Team have been talking about building a shooting gallery using Nerf guns to keep things nice and safe. Â This year I offered to give it a go and the spec quickly escalated/became more fun!
As I’m building this more for the team than the players it needs to be easy for them to use while dealing with the festival punters who are typically moderately inebriated…  Resetting the board easily, keeping track of the score and setting up for the next game seems like the three things to concentrate on.
The game works, or will work, as follows:
Press the start button, the counter should reset along with the targets
Give the player a Nerf gun and a clip with 12 darts
The player shoots the targets, which reset once hit, and the score is tallied
Having a bunch of clips that have 12 darts and a button that resets the game means resetting should be a lot easier than having to do it manually so that’s easy win, enter the Arduino!
I bought a bunch of hobby servos of eBay to use to reset the targets and designed a hinge with a magnet to hold up the target and a switch of some kind to track when a target is hit.
I’ve got a design working for the hinge but need to replicate it for all five targets.  More details once it’s complete but here’s an incredibly satisfying video of the mechanism in action!

Automated Broadband Monitoring on Linux
Automated Broadband Monitoring on Linux
I’m trialing a 4G home broadband router at the minute to see if it can give me decent upload as apposed to the 1mbps I currently get so I thought I’d look into automatically running speedtests.  Here’s how and it turned out to be quite simple.  Caveat, this runs on Linux.
There is a really handy command line util for running Speedtest.net which is a Python script.  To install it run: “sudo pip…

As long time readers of the blog may remember I tried to build a 3d printer many years ago without any success.  The problem was that at the time I didn’t really have a need for one, didn’t know what was involved or what parts I actually needed.  I also bought printed parts from one person on eBay, the metal bits from another seller, the electronics from another group again and so on.
Needless to say this did not make for an enjoyable experience.
Every time I got into building it I hit the point where I realised there was a part I didn’t know I needed and I’d put it aside for a few months.  Rinse and repeat.  It got to the point where the printer I started to build was obsolete so I’d have had to start again anyhow, so I donated what parts I had to the local RepRap usersgroup and they used it to build a printer for a local school.  I was happy with that.
Fast forward to now, or at least a few weeks ago, and I had need of a few random parts.  A case for a Pi, bits for the Roomba rebuild, bits for the Mini, the list is ever increasing this time around!  To that end I bought a Hictop Prusa i3 from Amazon which included everything which meant the whole project was instantly more streamlined!  One weekend of hacking, unhacking and rehacking later and I have a working printer!

It begins.
My shaft was too big for the hole, it took some effort to get them mated!
This hole was way too small for the filament so I widened it with a drill bit.
Only the wiring left to sort out…
I’ve printed out a few things now from Thingiverse but I’ve also started designing someone from scratch, more details on that soon, but this is proving a wonderful experience!

Keegan's Hat of #MigrainePrevention - #WearableTech
For whatever reason, back in early December, the ceiling lights at work have started giving me headaches which occasionally escalate into migraines, this is not ideal. We have a very helpful facilities team at work but I though I’d just find a workaround myself, as I like wearing hats this seemed an easy one to fix.
Behold, Keegan’s Hat of Migraine Prevention!
