Preamble
Having come across a brain teaser (see at the bottom of the page), and thinking that it could be solved using geometry, I needed a geometric drawing package for OSX, but one that would run on Mountain Lion…

Swapping a freehub for a cassette hub
Preamble
Leading on from 7 speed dilemas, I decided to swap the hubs myself and finally get around to learning how to build a wheel. Basically I’ll be taking out the freehub from a new cheap Chinese wheel and swapping it with a Shimano FH-RM50… However, nothing is as simple as it seems… especially when the Chinese rim and lacing differs considerably (and confusingly) from that described by Sheldon Brown….
ExpressCards on Santa Rosa MacBook Pro
Preamble
My 15″ Santa Rosa (2.4 GHz) MacBook Pro is seriously limited with its two USB 2.0 ports. So I thought about:
- Daisy chaining USB 3.0 passport disks – not possible due to them not having two USB ports (see Is there a way to daisy chain USB3 external hard drives?) and I don’t have a hub, although…
- … one option is to use a Seagate Backup Plus hub, big (at up to 10 TB) but noisy, or at least noisier that passport external disks)
- Using a Firewire to USB adapter in the (unused) Firewire port ( see Is there any usb to firewire adaptor?)
- Adding an express card…

Theme Park in DOSBox on OSX
Preamble
After playing syndicate (download here – the right mouse is used for fire, space does not work), I thought I’d try Theme Park (also from Abandonware), but unlike syndicate which just unzipped, Theme Park is the installer and it throws a wobbly if not installed from a floppy – having the installer in the DOSGAMES directory (or folder) does not work…

7 speed dilemas
Preamble
If you already have a freewheel hub with a 7 speed freewheel gears (i.e. MF-TZ07) using an IG or HG (hyperglide) chain, this chain will only work for 6,7 or 8 speed gear sets. Any higher and the chain will not sit correctly on the narrower pitched gears… see Bicycle chain – width:
- 6 speed – 7.3 mm (9⁄32 in) (Shimano HG), 7.1 mm (9⁄32 in) (SRAM, Shimano IG)
- 7 speed – 7.3 mm (9⁄32 in) (Shimano HG), 7.1 mm (9⁄32 in) (SRAM, Shimano IG)
- 8 speed – 7.3 mm (9⁄32 in) (Shimano HG), 7.1 mm (9⁄32 in) (SRAM, Shimano IG)
…
Shimano uses the same chain types on 6, 7,and 8 speed designs.
So if you need to switch wheels to one using a cassette, and you want to retain the existing chain, then you will need a HG gear cassette, as a CNXXXX will not fit the chain. So a Shimano CS-HG20 7-Speed Cassette (13-23T) would do the job. Note that a spacer may also be required.
Also ensure that the hub/cassette is hyperglide (or compatible).
