Long time before I bought a electric plug with WLAN adapter, I wanted to use to turn on the light in the garden (also for the water pump and such stuff). But this WLAN switches are really bad, always want connection to internet only usable via a very shaky app always want so many access rights who knows for what, always must log in. I switched after a while to radio controlled switches at 433 MHz and bought a Raspi 433 MHz sender.
Of course I wrote a own server program in FreePascal running on the raspi. It’s not very complicated in principle the WLAN switch just send a part its of the MAC address and a Token you use to switch on and off. was not very difficult, with the http server example from FreePascal I also added a little Webserver to it, that I can control it via browser or standalone apps. The NodeJS server needed > 10% of the Raspi, even there is no WLAN switch connected to it (because it stops when I start it 😉 ) FreePascal, with connected switch and a browser pulling the status <1% CPU time. Without WLAN Switch it’s not noticeable at all.
And because we are on a blog for FPC for Amiga-System I wrote a little MUI App to control the Outside light from my Amiga as well.
I’m really thinking to buy more of them. really nice and easy. Let’s see the next weeks how reliable it is. 😉 The advantage to the 433 MHz radio controlled switches is that the WLAN switches know their own status, and tell the server on the handshake.
A while before I played around with the SMP AROS version sadly I never really got it to work. Either it was just crashing or do not use all cores and now the development of it seems to be frozen. The AROS devs published a Video how a buhddabrot fractal was calculated with multiple threads.
I took that idea, because the buhddabrot fractals look beautiful and wrote an own buhddabrot program in FreePascal to test that with the SMP. But now SMP AROS basically dead now I found the program again and played a little bit with it, make it single threaded and created a little GUI for it, to play with parameters.
I used the function parser for a function plotter before when testing the TAChart for LCL. Now I gave my Plot component I use for MUIMapparium a little bit of reshape and fit it into MUIClass components and created a new function plotter.
I little video to show how it works:
Running on a Amiga 1200 with 68030 50 Mhz and 68882 50 Mhz on a 32 color AGA Screen. For Hex2 the floating point calculation speed is not very important, because it’s just a single function. But for calculating the full curve it needs a little bit more floating point calculations. Therefore a FPU is included. Also you should limit the number of Points to calculate to for example 100. For NG Amiga systems of course you can increase it to higher numbers.
Of course, when publishing a new program the people will find some problems. Good so at least some used it :-P. I made a new release. Added integer divide and modulo and repaired the swap function (swap endianess) and fixed some minor bugfixes and number overflows.
Downloads for all Amiga Platforms:
The program is based on a very old program (written around 2005) written by me so of course it is also available for Linux and Windows. It has a little bit smaller feature set than the Amiga version but it was always useful for me 😉
I created a little MUI interface for my commonly used calculator Hex2. I use it often for bitwise comparisons to easier see shifts on bits.
If you don’t know it, Hex2 is a programmer and scientific centered calculator with variables support and a little GUI even it’s keyboard centered. Of course I created it with MUIClass, therefore its available for all the common Amiga platforms.
First real release of the Extron Control as Version 0.1.
Control Software for Extron DSc 301 HD, Scaler and input switch.
With the new version you can configure, which parts of the GUI is visible (via tooltypes) and also configure the names on the Input Switch Buttons and which serial device to open and search for the Extron DSC 301 HD.
For Amiga and MorphOS the executable is included. But the source is also in the archive, hence one could compile them for AROS or OS4. (it just needs the latest Version of MUIClass).
I bought that device, its a very nice scaler nicely usable for old computers to bring the image in a good quality to modern monitors. I supplies a serial interface for controlling (beside the on screen display) but only a Windows program to use it. I wrote a little program to operate this device from Amiga/MorphOS (where you can use the USB connector at the front panel as a USB2serial bridge). Already working very nicely, some screenshots.
You can switch the inputs, it shows which input is selected (it also notice the change when you using the front panel). When an input has a usable signal the button is printed in bold. It’s an very early version but works already nicely, if someone it interested I just make a download available here (binaries for Amiga68k and MorphOS and the full source, licensed under CC0, it needs the last MUIClass package to compile, just yesterday I fixed some bugs there, should also compile for the other Amiga platforms) have fun.
Traveling is nice, but also nice to be back. As wrote in he travel blog entry I worked on the MUIIDE, especially on the Menu creating stuff, which is quiet difficult things, but prepares other stuff to come (like listview and lists). You can create now very easily Menus with Submenus with the IDE.
There seems to be a little bug, sometimes when I change a combobox active entry, the GUI does not follow it. I debugged it a little bit, and it seems like and updating problem, because after resizing the window everything seems to be normal. Needs some more investigation.
I’m currently on travel in Hong Kong, China and South Korea. I bought a PowerBook to take with me as my only Computer (+ mobile phone of course). The plan was to work a little bit on the free time on the MUIIDE and try MorphOS on the daily use.
Now some time is passed and it worked rather nicely. I had some problems in China to connect to the WLAN access point (it somehow worked but very slow). I switched to mobile phone 3G/4G WLAN sharing (iPhone) to MorphOS which works nicely. In South Korea and Hong Kong the WLAN in Hotel works flawlessly. Now it’s common that every Hotel room has it’s own WLAN access point in the room. If you often switch the Network it’s a little bit trouble, because sometimes the Network will go down when then WLAN disappears but will not come up again if it appears again (or an other known one). Even go to Network settings and force to the new WLAN does not help, but after a Restart of the Computer everything is fine.
Basically that’s the only problem I noticed, everything else works nicely. listing music with Digital Audio Player, Check emails via OWB or SimpleMail, Check my servers via SSH, Watch movies with MPlayer (via from USB Stick) writing code with Scribble, compile with FPC 😉 handle git with MoGit and git, surf Web with OWB (shows nicely chinese characters) and of course write this Article with image upload ;-). Overall not bad certainly daily use compatible for my usecases.
