The “Lament Configuration” is the name given to the wooden puzzle box that features in the movie Hellraiser. In the original book (The Hellbound Heart by Clive Barker) the box is black lacquer and needs to be completely disassembled for the gateway to Hell to open. For the movie a more intricate looking box was […]

I got an email from Dan Wilson about the recent Jarre gig for the Monaco royal wedding. Looks like an excellent concert, although the laser harp had some issues – and JMJ didn’t look too happy about it. I found this video on Dailymotion (with apologies in advance for all the ads they make you […]

I posted a while back about the JVC camcorder I bought, and how it had the high-speed shutter mode – it also has a variety of time-lapse modes too… The crystals are the “sodium silicate” kind you get at toy stores, and the clock I built myself…

DIY CNC: Carving a clock face

June 20, 2011

I’d been putting it off for ages, but I thought it was about time I upgraded my CNC skills to use multiple tool changes. Since I added a home sensor to my DIY “BlackToe” gantry there was no excuse not to figure it out. This relief cut uses 1/4″, 1/8″ and 1/16″ bits to perform […]

The Arduino controlled Electromagnetic Pendulum Clock

June 5, 2011

OK, only about 100 years too late – but I finally managed to assemble the clock works for the electromagnet-driven pendulum clock. The primary drive is a 15-tooth ratchet. This is connected to two 60 tooth gears that creates the second hand drive. A 60:1 reduction gearing comprising 10:108 +18:100 (the largest gears) creates the […]

Some early Jarre studio footage

May 31, 2011

Came across this clip on YouTube. I love this stuff. Way back before personal computers and emulated hardware were so prevalent, this kind of thing was pure magic… [Fairlight!! - Ed] …and if you’re wondering if all those vocal samples were ever put to good use, check this clip out…

Electromagnetic Pendulum – making it tell the time

May 31, 2011

A while ago I posted a video showing a pendulum driven by a pulse motor: It worked by using a single coil to detect the field from a magnet embedded in the pendulum base. An op-amp (wired as a comparator) detects when the pendulum reached the equilibrium point (vertical) a voltage (5-12v) is applied to […]

Aligning 40 Watt laser mirrors, without burning your eyeballs out…

Since the laser cutter has a fixed tube, and “flying” mirrors – it’s critical to get the alignment right over the full range of gantry movement. It occurred to me that if I could actually *see* the path of the laser, it would make mirror alignment a whole lot easier. Video also features my $25 […]

More information on the (ongoing) saga of my recent purchase… Using a multimeter it was easy to work out the wires coming from each motor. They are bipolar and so two pairs of the four wires will register a resistance, these are the A and B coils. They require 24V and 0.5 Amps. They stay […]

The primary ingredients… Optional ingredients, to taste… This is what delicious *and* moist looks like, on the inside… Every bit as difficult as it looks. Gravity is not your friend right now… The cherries go on just before serving, or *everything* will turn pink. Portal Cake Too. UPDATE: The cake also has coffee and 100% […]
