Raspberry Pi is a great piece of hardware. It packs powerful hardware inside credit card sized (85x56mm) board. Except it lacks decent case. Until now!

So, I designed adapter for Iphone. This adapter attaches directly to en eye piece, so any microscope can be used. This adapter can be made at […]

Apple portable devices have nice feature to listen for music over the air. It is called AirPlay. On the other hand OpenWrt has tools (avahi and shairport) to play audio stream from your gadgets.

Vieną vakarą kilo mintis pastatyti kamerą kur nors toliau su gražiais vaizdais. Prisiminiau Ventės rago ornitologinę stotį. Susiradau Internete kontaktus ir paskambinau. Vytautui idėja patiko. Pažadėjo duoti elektros ir Interneto. Praėjus keliom dienom nuvažiavom į vietą, kur pasitiko linksmas, šmaikštus, gerai nusiteikęs ir svetingas kolektyvas.

Logitech C920 is a wonderful webcam. It produces good picture quality and has hardware H.264 encoder. It can do real full HD streaming (1920×1080 p @ 30fps).

Preš kelias dienas ant aukšto pastato stogo pastačiau dar vieną time-lapse fotografavimo stotelę. Šį kartą sumontavau seną kompaktinės klasės fotoaparatą. Anksčiau publikuotame straipsnyje aprašiau kaip jungiau DSLR fotoaparatą – šį kartą kiek sudėtingesnis uždavinys – Canon G7.

I had an old Russian lens (MTO-500) laying around for a long time. Tried using it on DSLR, but because of lack of image quality I refused this idea. Today I mounted webcam on it. Because of smaller image sensor magnification is much larger in this conjunction.
