…fixing up a Roland Juno 60 synthesizer

A couple of years ago I bought a Roland Juno 60 from eBay. It was in “fairly good” condition but was very dirty and the faders did not work properly. There also seemed to be a sticky (beer?) substance on all the keys that was less than attractive. Additionally the programs weren’t being saved correctly […]

Good news! The laser tube, power supply and cooling system arrived yesterday. The 80W tube is *MASSIVE* – even though I knew the dimensions before I ordered it, I guess my subconscious had chosen to ignore the fact of exactly how long this thing was going to be. Hmmmm… I might have to move my […]

It turns out that the laser tube I have will not work with the generic PSU units on E-bay. Not entirely sure why this is, but I did notice that the insulation on the tube is starting to *melt* so maybe it’s time to move on. So… it looks like my only option right now […]

As part of the “Great Create” I was challenged by my buddies at Make magazine to complete a set of projects only using parts from Radio Shack. For my first project they tasked me with reproducing the rather excellent 555-timer “Whack-a-Mole” game created by Jim Chen. This one was tough… oh yes… very tough. Eventually […]

I had to dust off an older laptop recently and found to my dismay that the battery was not charging under Windows 7. Apparently this is a common problem – my laptop is an HP DV9730US, but many makes and models all seem to have the same issue. I tried the fixes that involve removing […]

Adding a laser cutter to the BlackToe CNC Mill

It’s time I took the CO2 laser from the Chinese cutter and attached it to the gantry of my BlackToe CNC mill. Effectively increasing the size of the cutting bay from the tiny 5×8″ to a whopping 2’x 4′ – the small size of the cutting area was starting to become annoying – and it seemed ridiculous […]

The Clock Of The Long Weekend…

July 25, 2011

I’ve spent a lot of time on the “The Long Now” website lately – I would urge you to check it out if you’ve not seen it – one of the things that caught my attention was the 10,000 year clock they are trying to build in Texas. Inspired by the design, I thought I […]

… “conflicting accounts” in Google Apps/Youtube/AdSense etc…

July 20, 2011

I don’t normally write about this kind of thing – but what an “absolute bl**dy nightmare” Google’s recent account updates have been. I have a Google Apps account for my domain, so that I can use the Gmail style interface to read my email – this all worked fine for a long time, then Google […]

Wood-cut Iris mechanism

July 11, 2011

I’ve been spending some time on the Thingiverse site just lately. The site is for owners of 3D printers, and allows the exchange of print files. The ‘iris box‘ mechanism looked interesting, and easy to adapt for CNC milling. So I downloaded the object files and extracted the face details as a toolpath. I cut […]
