Not so much Retro as oldish Tech Hack
One of our old digital camera’s got scared and leaked its battery juice all over its insides and stopped working … so
Easy project to convert it to an IR camera whilst cleaning the acidy goo from its innards;
Vivitar 5188 – 5MP CMOS camera – Dead cheap and came with a wicked underwater housing;
Step 1, remove all the screws;
Step 2, remove the front and back case. Be carefull of any wires that are still connected.;
Step 3, carefully unscrew and remove the lens assembly;
Notice how the lens is red in colour, this is the filter that blocks IR light in normal operation. This has to be removed (carefully of course).
I did try to scrape away the red coating, but scratched the lens 🙁 – removing it seemed the sensible option as its not a focusing lens and not really needed!
Step 4, get yourself down to the local photo processing place and ask for some film that has been developed but has no image (It should be almost completely black when looking through it) – There may also be some on your own negatives. I was lucky and had 1 frame of completely exposed and developed film with no image on it.
Cut out 2 disks the same size as the lens and place them back to back so no visible light can be seen.
Secure them in to the lens housing with 2 spots of superglue (1 on each side) making sure you do not cover the screw thread on the lens.
Step 5, re-assemble the lens in the camera holder and tighten as far as it will go, but do not over tighten as you will touch and then destroy the CMOS sensor and this mod will be useless!
Step 6, start taking surreal alien like pictures with your new IR wavelength camera!
I have an AKAI MPK mini 25 note keyboard with drum pads. Its a mini USB keyboard that works with loads of music software and DAWs.
This is a great piece of kit, but due to its portable size, does not have pitch or mod wheels;
REASON is my music software of choice, and many years ago, I found a blog post on how to re-use old PDA’s as KAOS pad replacements in Reason or any other midi composing software.
I have transferred it from my old blogger site which is being closed down on Aptil 29th 2019.
Searching the web does not produce much other than 2 ideas.
1. Sell the keyboard and buy the AKAI APK49 – larger keys and pitch and mod wheels
2. Use a Pocket PC as an X/Y pad for pitch and mod control.
This is the Retro aspect, otherwise this would be too modern for me!
Number 1 is out as I just bought the thing and love its compact size… So.
The second option it is then;
I use Reason Essentials 1.5.1 as my main DAW (Or try to as I am not very musical, ROFL)
Here is the process I used to get a vintage Windows Mobile 2003 Pocket PC (Dell Axim X30) working as an X/Y pad with Reason 10. (just like this one, but I have run it on many different versions of Pocket PC as long as it can run .Net framework!)
Using google, search for LoopBe1 midi loopback driver – LoopBE1, download it and install it to your main machine
Install Active Sync 4.5 if you are using Windows XP, or use Windows Mobile Connection centre if you have W7 – Not sure about Windows 10 as I use this on a retro specific PC,
Search on google for Theresa Pocket PC Theresa Download and download the ZIP file and extract it to your desktop to a folder called Theresa
From the Theresa folder on your desktop, copy the server folder to somewhere accessible on your main machine and create a shortcut to the .EXE file (So you can run it easy when you need it) – You can set it to auto load, but I dont like too many things loaded unless I need them
Connect the Pocket PC to your main Pc and allow it to be detected and with Active Sync or Mobile Centre, then cancel when asked to set up a partnership (This is not needed. You can set one up if you wish though)
Explore the PDA/Pocket PC device and copy the client folder from the Theresa folder on your desktop to somewhere on the PDA or a memory card
Run the server exe file from where you copied it and you will get a new T icon on the task bar – It should have a little red dot at its top right
Run the client exe on the PDA
You will be presented with the main Theresa screen on the PDA. At top right is the power button to close the app. Next to it you will find the config button. Select this and you can choose which port the software will affect.
Click on the top option (DEVICE:) and you will be presented with a list of available ports on the PC. Select the LoopBe1 Midi driver/port and click ok. You have now set up Theresa to output midi data to the correct PC input driver
You can also change the skin of the software to match one of your favourite ‘Real life’ Midi Controllers
On your main PC, fire up Reason or Essentials or any other DAW you use (They should all work about the same)
Edit preferences and add a new control surface as ‘Other’, do not do an autodetect as nothing new will be found.
Now select the Advanced tab and enable loopbe1 midi driver as another input device.
You should now have 2 green ticks for input devices (one for your main input keyboard and another for the PDA X/Y Pad)
Close the window and add an instrument to Reason – Test it with your keyboard to make sure you get sounds
On the Theresa screen you will see little numbers in the green bar above each slider/pad area. This is the MIDI number that is transmitted when Theresa is used.
Click on each number to change it to your preferred MIDI channel/note/value etc
I changed the botton left vertical slider from 105 to 110 (This is the value of the LFO rate for OSC 2 in SubTractor analogue synth module)
Play a note and move the slider up and down with the PDA stylus – your synth sound should change as you move the slider, or whizz around on the top left pad.
Voila – a cheap (if not free) X/Y Midi controller – Its not quite a Kaosscilator or a Korg Nano Pad, but its not bad.
(I will add more screen shots as and when I get chance)
I have finally got hold of a Tatung Einstein Hardware Reference Manual. A physical copy!!
Its huge! – 12 inches tall by 8.5 inches wide and about 100 pages.
As with many books from old book shops, there is a musty smell to it, but I have to say, this looks to have been lying around for a long time. It needs a damn good airing.
I never had this in the late 80s when I originally owned an Einstein, so this is a revelation! Sure, I have read it online in PDF format, but there is nothing like having the printed matter in front of you for reference.
This should allow me to tinker properly and diagnose why my Einstein is poorly!
While I am waiting for a fix for my poorly Tatung Einstein, I thought I would get some emulation configured so I have refreshed myself for the actual hardware.
Here is how I did it.
My OS of choice is Windows 10 – Your OS mileage may vary!!!
Go to http://www.emulator-zone.com/doc.php/misc/mess.html scroll to the bottom of the page and download the preferred flavour of MESS. I am using the 64 bit version
Install it. I chose c:\software\mess as the installation directory
Go to http://messui.1emulation.com/ find the MESSUI download section (About half way down) and find the matching version for the MESS you downloaded in step 1
Extract this 7Z file over the top of your mess install folder and overwrite when asked
Open a command prompt (I did this as administrator)
Navigate to the MESS install folder c:\software\mess
Type mess -cc then press enter/return
This will create a default configuration file (mess.ini)
Using your favourite text editor, edit this file and change the file paths by adding the MESS install locations in front of the folder names IE: rompath c:\software\mess\roms
Save the new configuration over the existing file and exit from the text editor
Go to http://www.tatungeinstein.co.uk/front/messmame.htm scroll to the middle of the web page and follow the instructions for downloading and saving the 3 files needed for the emulator
Run MESSUI64.EXE from the installation folder and you should be presented with the GUI to launch your system
In the top right search bar, type Einstein and you should have 3 systems listed in the middle of the screen
Ignore the no entry icon – this appears to be a bogus warning and is infact working!
Highlight Einstein TC-01, right click and select properties
In the Audit tab you will receive an error about the rom not being found, but this is a bogus error as the emulator will run fine. Check the settings for this machine an when you are satisfied, close the properties box
In the 3rd column of the main screen you have the option of inserting a disk image into the virtual floppy drive on the einstein. Click on the ‘Assist Edit’ button to the right of FloppyDisk1 and select Mount File
Choose a zipped Einstein disk file. I chose XBAS.ZIP
Double click on the Einstein TC-01 entry in the machine list and you should get the emulated machine booting
If the window is too small, maximize it like a normal window and it will scale properly to the correct aspect/zoom level. Be warned, the original Einstein screen was 280×216 pixels so the zoom will be excessive!
Press OK to access the emulated Tatung Einstein
To reboot the machine, use CTRL & left ALT keys – This performs a CTRL & Break sequence from the original machine
And thats your lot! – You should now be able to properly emulate a Tatung Einstein TC-01. The same instructions should work with the Einstein 256, but I do not own the rom file for this version so haven’t tried it.
