Laser light is transmitted from behind the hologram whereas the image is transmitted to the viewer’s side. You can cut transmission holograms into different pieces and yet each of them will reproduce the original image in its entirety. In a transmission hologram, one must use the same laser light to view the object as was used to create it in the first place. The image consists of the white incandescent light being reflected by the hologram. Galleries generally display reflection holograms. This 3D image of the object is seen near the surface. The reflection hologram is a truly three-dimensional representation of the object. To be able to see a reflection hologram, the viewer must stand at the side of this light. This light is placed at a specific distance and angle. Telephone by Iñaki Beguiristain, reflection hologram.Ī spot of white incandescent light is used to illuminate reflection holograms. However, there are several different types of what are called “hybrid holograms.” In this article, we’re going to talk about the many different types of holograms.īefore we move on to the finer details of the hybrid holograms, let’s first have a look at the common types.
There are two main types of holograms: reflection holograms and transmission holograms. It will keep on having a significant impact in moving fake identity card archives to the following phase of improvement, guaranteeing quality and checking the exchange counterfeit IDs while those records not showing security 3D images are seized and annihilated. Let me know in the comments what you think of the build.Planning ahead, while holography without a doubt faces difficulties as ID innovation and related criminal conduct keep on advancing, on the off chance that it stays zeroed in on its job as a powerful, adaptable and dependable enemy of forging measure, then, at that point its situation among governments and those answerable for law requirement will be guaranteed.

This brings the sample rate down to a lovely buttery downtempo speed when the pot is at max.Īt the end of the video I’m jamming with the looper and I passed it through some delay which really enriches the sound and creates some awesome loop-based soundscapes.Īll in all this project was a lot of fun to work on and I’m really excited to create some LoFi sounds with this module.ĭefinitely go check out Lonershy’s video as he talks about the pinout and how to rig up the chip for sample and playback. I replaced the SMD timing resistor with a 200k potentiometer and a 56k resistor in series. I’m using the 7805 5V voltage regulator to get the voltage down to under 6V needed for the 1820 chip. The module is run off of a 9V center negative guitar pedal wall wart. Additionally, these chipboards are really easy to work with and only require a few components to get a DIY sampler going.įor my version of the sample looper, I chose to just create a Eurorack based enclosure/faceplate so that it could be used easily in that fashion down the road. The chip doesn’t sample high-quality audio so when you stretch the sample it breaks down even more adding to the LoFi bit-crushed feel. So, this makes it easy to add a potentiometer and pitch a sample down for a real slowed down LoFi feel. My favorite feature is that they have a resistance dependant sample rate. I love these boards because they can be purchased online for very cheap.

If you have played with one of these I’d love to know where you got yours and if you enjoyed it.Īs always, I have included a free sample pack of the sounds for use in your projects.
According to the small sticker with instructions on the back, it appears that there are a few memory banks that you can store to by pressing the play and number simultaneously. I couldn’t get the record and playback function to work on my model but it might just be that I don’t know how. There is a Mattel version that is a lighter gray so I’m guessing the target market was young teens in the late 80’s or early 90’s. Like so many drum machines of this era, I believe this was originally sold as a toy. At the time of writing this, one can be won on eBay for a starting bid of $50 bucks. The best part about this little guy being so void of features is that it makes it much more affordable. While it’s no match for the fabled (and nearly unobtainable) Roland TR-808, it’s still a fun little analog synth drum. Today we go through the sounds and features of this rare and forgotten classic, the Synsonics Drums.
