Toshiba TLP-WX200

ヒューズ(T6.3AH250Vセラミック)が飛んでいましたが、 こういう場合たいていFETも飛んでいるので１次側を追おうと思ったらランプ基板も１次側。 切り分けのため電源基板(APS-N802)だけで通電したらやっぱりヒューズ飛ぶので FETをテスタで当たったらIPA60R199CPの1つがSD間短絡。 同じ品を購入すると本体購入価格を上回る(笑)のでTK20A60Uに2つとも交換、完了。
しかしこれ、FETとダイオードブリッジに修理跡があるんだよね。 FET並列で使ってるし、待機電力減っただけの新機種が出てるし、 まあいわゆる「設計ミス」ですな。多少オン抵抗が小さいのに交換したから長持ちしてくれるといいな。

何気なく裏面見てるとWinCEのライセンスシールが。 そういえばこの機種、Vistaのネットワークプロジェクタに対応してるんですが、 これRDPプロトコルなので、事実上WinCEマシンでないと実装できないんですよね。 USBとLANとWifiが載った別基板があり、ここにTIのDAVINCIが載ってます。

ネットワーク経由で制御できるのですが普段使いにはやっぱりリモコン、 でも別買いすると本体購入価(略)なので、WinLIRC+MCEで6万通り試すコード流したら運よく3分で判明。 学習リモコンに登録できずにubuntu+lirc+mceusb使ったりしてみたところ、RM-VL501は変調38KHzでないとだめみたい。

RICOH WX4130N

故障してなくても両側網→後面→前面(フォーカス側)→上面の順に分解。 網は細いマイナスドライバーで上部ツメ２か所を押す。 前面は、内側でも金属板経由で止まってるので銀ネジで金属板ごとはずす。 上面は金属同士を止めているネジをはずす。あとは上部ガラスはずしてそこから主鏡掃除。
なんていうか非常にコンパクトで一見華奢にもかかわらず最低限の部材で緻密に強度計算されており、 さすが東芝の系譜+リコーのカメラ技術というか。

ゲームで必要時に床置きして壁投影ってかなりいいのですが、 ここまで超短焦点だと小さなごみでも影がかなり長く出ますし、 壁って意外と平面出てないので特に上辺が歪みます。 実用上はWX4240Nぐらいが使いやすいです。 ただ、どちらも教室向けなのに取っ手がないのがダメ。 ケースで十分との判断かもしれんが、セットアップの時間が長くなるんだよ。
東芝系はPOWER+MUTE+DOWNに電源コードでランプリセットです。POWER+RETURN+MENU等の機種もあります。

Raspberry Pi Zero - KODI standalone player

(autoexec.py)
execfile('/media/DATA/start.py')

(start.py)
import xbmc
xbmc.executebuiltin('PlayMedia("/media/DATA/Video/","isdir")')
#xbmc.executebuiltin('PlayMedia("/media/DATA/Video/list.m3u")') #BOM無しUTF8で漢字ファイル名OK
xbmc.executebuiltin('xbmc.PlayerControl(repeatall)')

1. 設定→Media→GeneralでShow hidden files
2. File managerに / を場所登録、以下File managerから
3. /usr/share/kodi/addonsのskin.estuaryを/storage/.kodi/addonsにディレクトリ毎コピー
4. skin.estuary/xml/DialogSeekBar.xml, DialogBusy.xmlを/media/DATAにコピー、kodi終了
5. microSD上のDialogSeekBar.xmlの3行目付近の Player.Seeking | Player.DisplayAfterSeek | を削除
6. DialogBusy.xmlの9行目付近の + !Player.Caching の後ろに + !Window.IsVisible(fullscreenvideo) を追加
7. kodi起動しFile managerから/storage/.kodi/addons/skin.estuary/xmlに上記ファイル2つを上書き。

Pi ZeroついででHDMI Lag Tester 簡易版 をインストールして測定。 1080p60、eco、グラフィック、SweetVisionオフ、壁紙オフで0.5+1+0.4=1.9フレームはゲーム可ですが、 3CCDなのに明らかに赤が速い。NV1301はDLP版と共通なのでそのあたりの都合？
