Bluetooth + phone == remote control

Wednesday, January 2nd, 2008 by Marcin Juszkiewicz

During holidays I found another usage for my current phone (SonyEricsson k750i). It is Bluetooth Remote Control functionality.

Basically it turn phone into HID device but the good thing is that user can create own profile for this. There is a tool for it (Microsoft Windows executable) and also those files can be created by hand (instructions are provided by Stefan ‘tommie’ Tomanek as part of his excellent guide about using this cellphone with Linux).

I do not know does it is possible on Neo1973 (IIRC BlueZ only has HID daemon) but I will miss it if it is not…



VoIP: headset, USB phone or BT headset?

Monday, November 12th, 2007 by Marcin Juszkiewicz

During Wednesday I will have conference call to discuss some things with few developers. Before I used cheap VoIP headphones with microphone but one of cables broke so mic works or not.

So it looks like I will have to buy something again. During OEDEM Stelios used USB phone to make calls and it looked more handy then ‘VoIP headset’. But there are many of them on market so what if I will end with something which works only under MS Windows?

Other choice is Bluetooth headset. This one will be also usefull with my cellphone or Neo1973 or even with Nokia 770. Configuring headset to work with Linux was disaster but I googled a bit and found that with bluez-utils 3.16 or newer it is no problem (or at least it looks like that).

Which one to choose… Have to sleep with this and take decision tomorrow.



Zaurus machines starts to be obsolete…

Monday, November 12th, 2007 by Marcin Juszkiewicz

Time passed since last Zaurus (SL-C3200 ‘terrier’) was released. Many new interesting devices appeared on market: Nokia N800, FIC Neo1973 and now Nokia N810. Each of them has something extra compared to Zaurus machines — Bluetooth or Wifi or GSM. And each is supported by vendor — thing which cannot be told about Sharp.

Recently few OpenEmbedded developers (Koen, XorA, Mickeyl) wrote that they got developer discount1 for Nokia N810. What does it mean for Zaurus owners?

When developers gets new toys they usually look at pile of palmtops and decide which one go to drawer or eBay and which one will be used. For example I have 8 palmtops2 now and most of time do not use any of them. I will probably use Neo1973 as main PDA when it will reach usable state and rest of devices will be used from time to time to test something. XorA wrote that he will sell own Zaurus machines and give OE devices to someone who wants to maintain them. Koen already do not use his c700 at all, same probably with Mickeyl. As result Zaurus machines will get less and less maintained and will bitrot in next year or two :(


  1. There was developer program for Nokia 770, then for N800 and recently for N810. I tried with first one and ignored others as they support only developers from few selected countries

  2. Those 8 palmtops are: PalmPilot 5000, Palm M105, Sharp Zaurus SL-5500/c760/SL-6000L (OE project device), Nokia 770, 2 FIC Neo1973. 



Phone should have a mirror

Saturday, November 3rd, 2007 by Marcin Juszkiewicz

Recently my wife decided that her next cellphone needs to have a mirror. This was after her last trip when she forgot to pack mirror into her purse…

Why such requirement? Currently Ania use SonyEricsson k510i cellphone. It has Bluetooth, Irda, camera, J2ME games/applications, possibility to use own themes and many many more functions. But to tell the truth — how many people really use such things? During phone numbers exchange they just manually create new entry in addressbook because even if they have BT or Irda they do not know how to use it or are afraid of catching viruses (really!). She sometimes play pre-installed J2ME games or use one application: public communication timetable (which I installed and take care of updates).

Will Neo1973 running OpenMoko be good for such users? I asked my wife and she told:

Yes, if I would do jogging — it fits nicely to tracksuit.

My brother-in-law is more interested, but he like technical things. Not like my wife — she just wants to call, message and use a mirror when to comes to using a cellphone. And of course it has to good look and fit her style ;)



OpenMoko testing weekend

Monday, October 29th, 2007 by Marcin Juszkiewicz

When last time we were in Szczecin to visit her family one of my brothers-in-law told me that he would like to get Neo1973 phone as replacement for his current Nokia one. So this time I took GTA01Bv4 (plus additional battery and external battery charger) to give him for playing during weekend.

He likes overall look of phone and started playing with software. After some time he managed to enter data into Contacts and Tasks, also tried to play few games. We found few small bugs and I entered them into bugtracker:

Last one is probably hard to fix as I do not know is there a way to get notification on screen rotation. I suggested to Mickeyl that ‘on Power hold’ menu should be rather replaced by fullscreen window with status of GPS/Bluetooth/WiFi/GSM and options to disable/enable each of them. Also possibility to switch on “Flight Mode” and change profile should be there. If it would be made in proper way then there would be no problem on screen rotation.



NSLU2 joined under-desk machines

Tuesday, May 15th, 2007 by Marcin Juszkiewicz

Today I bought Linksys NSLU2 machine. It is small, ARM based NAS and it is running Linux out-of-box. Unpacked, connected to home network and after checking that it is working I reflashed it with OpenSlug 3.10. So now it runs 2.6.16 kernel (instead of old, hacked 2.4.something) and opensource system (built with OpenEmbedded).

What for I bought it (other then taking space under desk)? I plan to run few services on it:

  • NFS server with DL_DIR contents (all sources used by OpenEmbedded builds)
  • TFTP server (to server kernels, rootfs images for miscelanous devices on my desk)
  • SMB server (music, movies)
  • Bluetooth access point for my Neo1973 phones and other devices

Too bad that small embedded PCs are harder to get that such gadgets. I hope that one day I will be able to buy machine which will replace my WiFi AP/router and NSLU2 (NAS, BT AP) in one.
