Sine I have slowed down in the laser hobby , thought I would list these two diodes .
I have them listed on ebay and that is where I would like to sell them trough as its much easier for me , I have the GSP option for orders outside the UK .
Both diodes where purchased used a while back...
Hi All .
This was my first attempt at building a small phase change system .
There was no real gain to be made from this on the CPU other than for the building experience : ) .
Specs are -
Secop 30AA 3cc R600a compressor
2.8m 0.8mm Capillary tube .
120mm 13W AC fan and 120x120x50mm...
This is a around 1mW green 543nm helium neon laser , it is in a metal tube but the end sufferd damage and was broken off leaving the ballast resistor lose , the laser is fully working though and has a nice thin geen beam .
The PSU is a 12V input unit rated for the tube , it has a TTL input and...
This has been a ongoing project for the past month or so on and off and I have finally reached the point where its working as it should .
Its a 12 Hour Nixie clock using Z700U trigger tubes and front facing nixie tubes , AM is indicated by a A and PM is indicated by a V ( for now ) ...
Due to current events I have put up my LGK argon laser and ITL5500 Argon laser up for sale .
LGK is a model 7812 with glass end bell , output is 14mW @ 9 lines @ 6.5A .
ILT is a model 5500 and dose 340mW 6 lines @ 11A , 30mW 4 lines 5A Idle .
Both are turn key systems 230V AC , plug...
This was a little project I did from the shift registers and arduinos : D
Video - https://www.youtube.com/watch?v=OOVk0ewZxIg , There is a start up pattern and I will soon say hello on power up .
6 digit clock is based on 6 6B595 shift registers , it uses a i2c DS3231 RTC that is...
This was a project I did over the last week . It's based on 3 dual BCD counters , 7 Quad AND gate IC's , One BCD-7 Segment driver and 4 4017 decade counters and a few resistors , LED's and 1N1484 Diodes , Transistors . Supply is 2 5Va transforms at 7 and 9 V and one 1.6Va transformer at...
This was my weekend project that I have nearly finished ( just need to do low voltage PSU, Power connector )
The overall goal was a open top cassette player and stereo valve amp all in one box .
short video can be found here of it running -...
Well after a while I took the jump and purchased the big brother of the LZ4-40U600 4 die true 365nm LED engine UV led the LZC-70U600 12 Die 365nm led .
Specs are -
Dominant wavelength - 365nm
Output Power - 5W typical
Forward voltage - 49V Typical
Drive current - 700mA
Well after a while I decided to try and make a variable constant current source with modulation for diode testing
The circuit if partly from a PFD form analogue devices .
The basis setup is 2 op-amps one being used to drive the mosfet and the second is the current sense and feedback ...
Well after a while of the head sitting on my floor as im currently looking for a PSU I decided to build a simple , very simple setup to test the tube and see if it works .
The circuit is from sams LaserFAQ and is intended for testing only .
The 568nm output looks green on the camera...
Just in the process of finishing a simple EL project .
The setup consist of a rockbox1 Bluetooth speaker green , white and blue ultra bright EL wire and the EL switching which is the same circuit as the EL sequencer SF sell but I made it on copper strip board and used though hole...
Up for sale I have a 150mW + 473nm blue laser system with power supply and driver in one box .
The laser is used and is missing the top cover from the PSU and bottom cover from the laser as it was covered in epoxy glue ....
Laser outputs a nice thin blue beam and I have measured it...
Another argon to show , this time its a LGK 7812 ML4 and the unique thing about this argon laser is that the end bell with the cathode is made from glass which I love about this tube .
You can see the bore entrance too .
Unit was made in 2007 but I have no idea on hours and im not...
Well after a 1 hour drive I can finally join the argon laser club :D
The laser I won is a ILT ( ion laser technologies ) 5500A head and 5405 Model PSU , The laser head was made in 1990 so its just over 24 years old with the hour meter reading just under 100 hours on time .
I am selling both my 1W CNI OEM 532nm and 50mW OEM F 473nm laser systems .
The 1W 532nm does over 1.5W , The head MUST be mounted on a heatsink with good thermal contact and a fan if anything or power will drop .
The 50mW 473nm does around 65mW .
1W 532 comes with driver and power...
Well i have decided to take a break from lasers for a while so I am selling both my CNI oem lasers .
The first is a OEM-F 1W 532nm system that does 1.45W ( Nice tight beam )
The second is a OEM-H 1W 532nm system that does 1.5-1.6W .
Both come with driver , PSU , laser head .
