I love my old Bose Quietcomfort 15 headphone, so much that I decide to add a Bluetooth receiver to it to keep it in service for a couple of more years. During the process, I needed to DIY a short audio cable to connect the headphone and the Bluetooth receiver. I couldn’t find any information about the pinout on the Internet, so I disassembled the original cable to find out the schematic.
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. Because Thinkpad X41 is my oldest machine with a parallel port (on the dock), I tried to install Windows 98 SE 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.
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.
Continue reading “Bluetooth Receiver TT-BR06 volume mod”应用场景：局域网内有一台常开的低功耗server (例如raspberry pi)，同时还有其他几台需要远程唤醒的机器。可以在server上部署一个web服务来执行wakeonlan。这在路由器不支持wakeonlan packet forwarding的时候很有用。
Continue reading “在Ubuntu 22.04上使用uwsgi和nginx远程执行wakeonlan”俗话说授人以鱼不如授人以渔，写这个是希望留下一些对MO4引擎的研究结果，方便后来人查阅，也能给新手们一个关于移植工作的直观印象。
MO4的移植我只参与了资源提取和脚本解析两部分，下面说一说我的提取过程吧。如果有差错请指正。
Continue reading “秋之回忆4(MO4)移植经验”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。
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。

相信大部分拥有N770的同志们都是玩了一阵子新鲜劲就过去了，最后N770的命运大概就是被卖掉或者在柜子里落灰。其实，N770这种开放的架构很容易把它变为数字台历和数码相框，让你的N770发挥出余热吧！

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~
