How to install Windows 98 SE on Thinkpad X41

Recently I wanted to play with one of my old PDAs, and its sync software requires a parallel port and Windows 98 environment. Virtual machine does not emulate the parallel port well. Since X41 is my oldest machine with a parallel port (on the dock), I tried to install Windows 98 on it.

It turns out X41 was too “new” for Windows 98. There are some driver issues that I can’t resolve. But for my purpose, the result is good enough. So I’m documenting the process here, hope it helps others.

Bluetooth Receiver TT-BR06 volume mod

Last year I bought a TaoTronics TT-BR06 Bluetooth Receiver to use with my iPhone. It works great, and the sound quality is fine. The only issue was that the volume was too loud. I am using it with a pair of Sony XBA-N3 earphone, it was uncomfortably loud even on the lowest volume.

Recently I looked up for this product on Amazon, and I found a review that mentions a modification that can adjust its output gain. I tried it and it worked like a charm. So I’m documenting this mod here. Maybe it also applies to other similar brands of Bluetooth receivers. So if you have similar problems, you can have a try.

Sony CLIÉ PEG-SL10把玩

近期看到一个词:low-fi,专门形容那种喜欢古老技术的人,我觉得这个词很适合我,因为我喜欢十几年前的电子产品,它们简单、底层,没有当今那些花里胡哨一层又一层的技术包装,更能凸显技术的纯粹。黑白屏幕的palm就给我这样一种感觉。

黑白、干电池、带扩展的palm是我的理想选择,主要是因为省电、电池没有老化问题,并且不受可怜的内存的限制。市面上的黑白电池机有很多,但是m125和SL10是仅有的两款带存储卡扩展的palm(其实还有TRGpro、Handera 330这些老怪兽,市面上基本见不到了,我也就不想了……)。m125在半年前入手一台,SL10则迟迟没有合适的。甚至想过让朋友在ebay帮忙代购,但也没有价廉物美的。近期在tompda上看到这个机型,毫不犹豫地就买了一台。

Nokia 770从入手到精通(八)N770搜索不到wifi无线网络的问题解决

几个月前,我的N770忽然搜索不到wifi无线网络了。具体表现为:笔记本和ipod touch都可以搜索到并且连接到wifi,N770却搜索不到任何网络。我把N770拿到图书馆去,又可以搜索到wifi了,很奇怪的故障。

最近google了一下,在下面的网址发现了这个bug report。

Nokia 770从入手到精通(六)N770 的USB Host模式(下)软件篇

USB键盘的使用
如果完全按照上一篇日志来的话,切换到usb host模式,插上线之后键盘就应该可以工作了,但是键位有点别扭,比如主回车键在xterm下居然不是回车,得按小键盘上的回车键才行。
USB键盘要玩rdesktop的话,需要在rdesktop的选项中勾上“BT keyboard”,进去以后键盘操作很爽~

Nokia 770从入手到精通(六)N770 的USB Host模式(上)硬件篇

USB设备分为HOST(主设备)和Client(从设备),只有当一台HOST与一台Client连接时才能实现数据的传输。

N770默认是工作在Client状态的,所以连接到电脑上以后会以一个U盘的形式存在。现在我需要把N770变成一个USB Host,支持连接鼠标、键盘、硬盘、U盘、MP3、USB HUB、USB转RS232等一堆设备,好处多多。

哈哈,这只是画画饼而已,N770的确可以接上述设备,但是实用性不高。不过,对于玩机一族,还是很值得一试的~
