Restore IP cam password

I was forgotten the password and ip address for my Chinese Ip Camera. Tried everything, but it was impossible to enter the camera again.
Most cams and other ip device’s have a reset button to “reset to factory default” but this cam not.
With the help of Wireshark the ip adres was found looking at the broadcast the cam did.

Looking at this youtube clip is was clear it can be done with a tool called ResetConfig_V2.

Easier said then done. Looking for this tool trough all Chinese webpages was not that easy because I can’t read any word Chinese and google translate also not.
After some search finally I found the tool.
It worked great for me, was not that difficult to reset the ip camera after I changed the language to English in the config.ini file.

Have fun.

Tcp/ip gateway #2

 

UnderConstruction
For my Joshua domotica I needed a better tcp/ip gateway. The old gateway was only used as gateway, but this #2 revision will also be used as webserver to control the devices on the Joshua bus from a webpage so that it can be used from different mobile devices.

This new tcp/ip gateway will run on a Stm32F427 arm processor in combination with the Texas instruments ethernet phy DP83848. These combination is already tested and working well in this post.
For communication with the Joshua bus we have an Rs-485 driver, for storing images for the webpages  there’s a Sd card connected to the Stm32 with 4bit width sdio interface. There’s also an i2c eeprom on the pcb to store some specific Joshua network parameters.

To check the working of the gateway there’s a 320×240 color tft screen connected trough spi bus. This display uses the ILI9341 controller for the display and the XPT2046 for the touchscreen. The last one is fully compatible with the well known ADS7843.

For my previous arm projects i had used the Coocox ide, but after the update to the 2.xx version is become very crapy. Now I will use the Em::Bitz ide, known before as Em::Blocks.

Stm32F4 with ethernet phy

For my Joshua domotica bus i was looking for an new tcp/ip gateway and webserver to control everything from my smartphone.
The old gateway based on a Atmel mega32 was not powerfull enough to make nice looking webpages.

Searching the web i found a post from Jesper with a nice sample written with Coocox.
I was so disappointed about the performance , running on a 168mhz ARM the demo page loading took about 4 seconds including the images, my good old 8bit avr was even faster then that.
Also dynamic IP was not working, only dhcp, not that handy for my purpose.

To trying to get the problems solved i have updated most of the drivers in the project from version 1.0.0 to 1.1.0. After that everything was working fine.
The demo page loads now in a blink of an eye, even with IE and on an Ipad.

See for your self.

Oldies Joshua Predecessor

The predecessor of my Joshua Domotica , here’s a more detailed overview of the electronics used.

 

Joshua predecessor controller board

First controller board for my domotica. Was running on a 8052AH Basic and mounted in a 19″ rack with the other eurocards. Not in use anymore, everything can now be done with a simple avr controller.

Same board controller board, bottom view.

 

96 channel Ir-receiver board

Ir receiver board to belongs to the above Joshua predecessor controller board. A lot of electronics for something simple we now these days with one receiver and the rest in software.

Same ir receiver board, bottom view. Routing and making a pcb was 25 years ago not that easy and cheap so wiring the pcb with roadrunner wire was the simplest and cheapest way to make the pcb. Until you made a mistake…
You can’t see it anymore but there where different colors for Vcc, gnd and data, but after all those years the colors are faded.

 

Ir Transmitter

The ir transmitter for the above receiver board. I used it only to program my learning remote controller, so that’s why it’s not build for daily use. You can switch between 3×32 channels with the jumpers.

The original Elektor design only supported 10 channels so I hacked in the other 22 channels that the Ir controller was capable of sending  by adding my own keyboard.

 

Amplifier interface

The interface card between my domotica and amplifier. Looking at the empty sockets I have already recycled some ics.

And on the back side again a lot of roadrunner wires.

From this interface board also a picture of the frontpanel.

 

Speech card

And the speech card, based on the Sp0256A and the CTS256A processor. We had a lot of fun with this speechcard. Nobody understood what was said and I didn’t get that, I understood everything that was coming out of the speaker. Looks like because me as the programmer did know what speech there was expected and therefore understood it all.

Backside with all the roadrunner wires again.

 

Rf Remote

I had someday a crazy idea to make a Rf remote control for the Joshua predecessor. This was begin of the ’90 when it was a bit complicated then now a days. This is the test setup to develop the software.

And the prototype, ram, rom, cpu all separated in dip package. The project never was finished, hard to realize with these components.

And the back with a lot of roadrunner wire again. Realizing this compact print on a regular 2 or 4 layer pcbs is hard to do, but with the roadrunner wire you can make as much “layers” as you like.

The rf board with tx and rx module. You can buy these modules now for a couple of dollars, but then they cost €75 for a set rx/tx.

 

Oldies Various

Various projects that I have made in the past. Some are still in use, other are overtaken by time.

 

Audio power slave switch.

My subwoofer uses 11watt when in standby, to save some energy this switch will switch the subwoofer on when there’s audio. Still in use.

 

S65 Test setup
https://evertdekker.com/wp/wp-content/uploads/slider61/audiopowerswitch.jpeg
The test setup for my S65 library. Some “modification” are done to get it all working.

 

Yampp

“Yet another mp3 player” a mp3 player that plays mp3 from a hdd, sounds not that special now, but then it was very unique. Special when you made you own. This was my first serious smd project. Just a kit that I soldered together. Even the components where 1206 it was not that simple, mainly because I didn’t have a aporpiate solderiron and solder.
Now these days soldering 0402 and 0.4mm qfp package aren’t any problem. If you use the stencil method, it’s a piece of cake.

 

Xbox360 Glitch

Xbox glitcher pcb and jtag programmer to exploit the xbox360 glitch hack. Because the Chinese pcb houses give you 10 pieces of the same pcb for the same price there where some left overs that I wanted to sell, but selling was the hardest part. Glitching your xbox360 is in a grey area and therefore not allowed to advertise with.

 

Voice recording

Nothing special, a Velleman 2653 kit to record and playback sounds. Can’t remember for what I have bought it, maybe just for playing with it.

 

Velleman IO & AD

Build this one the log the energy generated by the generators at one of my previous jobs.
4 pcb’s packed with components to read 2 AD channels and 2 IO channels and send it over Rs232 to the pc, hard to imagine now these days with all the Arduino’s etc that can doe the same job, even better with only 1 chip.

 

Elektor 8ch AD

Use for the same project as above, but didn’t get this one working. Never knew why…

 

Satellite smartcard

Home brew smartcard emulator for analog satellite tv. Not my design but made the pcb myself.
Watched a lot of channels with this smartcard 😉

 

Mini Crescendo

Famous design from Elektuur (Elektor) magazine, the mini-crescendo.
This was the light version of the Cresendo mosfet amplifier, still using it. This board is from the post crescendo that I used as active subwoofer, the last one is taken out of use.

 

6802 controller board

Controller board with 6802 controller, ram (missing) and eprom. Never used it, didn’t had an eeprom programmer myself.

 

Automated cat litter

Some crazy idea of me; I forgot sometimes to clean the cat litter on time and then the cats pied some where in the house and I had even more cleaning up to do.
There was nothing to buy on the internet, only cat litters that removed the poop from the litter, not refreshing the litter.
Automated cat litter that cleaned the litter after 4 visits from the cats. This is the operator (for me, not the cats) front panel. Home made frontpanel with recessed button behind it, lcd display and connector to the top lid of the litter.

Backside of the controller board. The sub pcb is an power line modem that I wanted to use for the domotica, however the communication was that poor that I dropped the idea to use these. Module was also to expensive to use it for all the network nodes.

 

Voice recognition

Voice recognition was not new for me, have used already a long time but now it was time to make my own. It works, now I’m trying to port it to the Atmel Avr series.  Project still running……………….
