Hacking a Thrustmaster TX RW gaming wheel with Arduino Uno – part 1

TX RW Wheel connected to Arduino Uno

Here’s a Thrustmaster TX Racing wheel (Force Feedback TX base + Ferrari 458 Italia replica wheel). I got it broken, and because of the fact it required tear down and repair anyways (fixed already), I decided to play with electronics a bit more, connecting different wheel parts to Arduino board and reverse-engineering wheelbase-to-wheel wiring and protocol. Let’s take a look?

Monitor Skype disk activity in Mac OS X

Skype refused to launch today – failed with Disk I/O error. Had to delete the whole ~/Library/Library/Application Support/Skype/ folder to return it back to life.

But, on re-launch, Skype started to eat 20% of CPU – probably generating all caches/downloading avatars/… we just deleted. Hey, let’s find out what the Skype is actually accessing on a hard disk. How hard can it be to monitor that?

Open the terminal and type in a command:

sudo fs_usage -f filesys | grep -i skype | grep stat

How to re-charge alkaline button cell easily

1.5 volts alkaline cell

Wanna share a nice little hack I’ve developed recently – how to re-charge a 1.5 volts watch alkaline battery, or in my case – cycling computer cell (L1142, LR43 1.5 volts). Haven’t found one in a corner shop, so decided to make my one to live a bit longer. It’s not recommended to re-charge alkalines – use this trick on your own risk, please!

Okay, the things we need:

Italian, Lesson 10: Modal verbs, part 4. Sapere (know/know how/can)

Ciao a tutti! – Hiya all!

This is the last part about Italian modal verbs. But first let’s refresh our memory. We know 3 modal verbs (verbi modali) and theirs forms:

  • potere – can (posso, puoi, può, possiamo, potete, possono)
  • volere – want (voglio, vuoi, vuole, vogliamo, volete, vogliono)
  • dovere – must/have to (devo, devi, deve, dobbiamo, dovete, devono)

Today we’ll talk about fourth modal verb (or modal helper) – sapere (know/know how/can). Typical usage – we know and can do something well:

  • I can drive a car (I know how to)
  • I know how to cook

See, looks somehow similar to potere examples. But sapere and potere are different. Later we’ll see that. Continue reading
