This machine`s playfield features a catapult that fires the pinball, trolls that pop up from the playfield, and an exploding castle with a drawbridge and iron drop-gate. All the plastics were replaced with a New Old Stock (NOS) set from Marcos Specialties. I also bought various parts such as target switches, the steel castle gate, and dragon wings.

Extensive use of laser printed graphics were used to make overlays and decals such as for the castle drawbridge, troll flaps and other locations. The plastic ramps were stripped, cleaned and then flame polished. The metal ramps responded well to a rubbing of `Brasso` (unlike the IJ ramps, which did not), and came out bright and shiny. The edge of the castle gate was broken on the left hand side, so I decided to purchase a new one. However, when it arrived, I saw how little was broken, and decided to repair the existing one. Using fiberglass tape and epoxy, I rebuilt the left entrance. I also touched up the footers of all the towers and clearcoated the entire castle with non-yellowing polyurethane. This is the method first developed on the Space Shuttle ramps. I started by shooting a photo of the area with a ruler in the field of view. A resolution of about 300 dpi is a good target to achieve. I then edited the image to add the missing parts back in with PhotoShop. The image was then printed onto both photo paper and vinyl media from mediastreet. com. The former product is 6. 8 mils thick, while the latter is 6. 5 mils (normal office paper is 4 mils). I found that the former worked better in terms of the image quality in the solid areas. Whenever the vinyl was stretched, the colors would crack, so I used photo paper. I then glued the paper down with dry glue from a glue stick (prevents wrinkling of the paper), and covered...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
