It is time to build the E-Licktronic Nava, the Roland TR-909 clone! I’ve had the kit and a metal case for several years but I haven’t actually started building it. So about a month ago I ordered the remaining components from Mouser. In this video I solder and test the power supply. Nothing exceptional here;...
In this Yocto several of the distances/spacers used to screw the PCB to the front of the machine had been broken off. Some of them were loose when I got the case and some of them broke off due to stress when screwing them in. Here I glue these back using epoxy glue
Cleaning some oxide/gunk in the instrument switches of a Roland TR-808. Initial cleanup using air duster to get anything loose out of there. Then using some IPA and finishing off with some DeOxit.
This Roland TR-808 had very noisy snare, clap and toms. The toms especially sounded very coarse. It was a bit like when you try to stop your car on a road with gravel. The claps and the snares also sounded a bit tame or muffled. The common denominator between these instruments is the white noise...
On the Yocto v1.0 there is no option to install a power switch. So in this video I show how to install it by cutting & removing a trace and connecting the switch in series with that cut. Please verify with a multimeter that there is no connection between the center pin of the connector...
This x0xb0x had some issues with the bank selector encoder; it would skip over certain banks in a predictable pattern. My guess was that it was a bad/broken solder joint on one of the pins of the encoder.
More than a year ago a bought a metal case for the Yocto. This case was made to have an internal 230V power supply and an IEC connector. There was no hole for the original external power supply connector. As time went on I realised I would never build this internal power supply. I decided...
Replacing the potentiometers in a x0xb0x. Several of the potentiometers had some noise issues and they were possible to wiggle back and forth. We decided to replace all of the pots to have everything nice and fresh. I ordered the pots from Willzyx (http://willzyx.com) as it was easier and cheaper, mainly due to the shipping...
I have a Benq w1060 projector (which is about 8yrs old) which had severe issues with parts of the projected screen having lighter areas. It also projected light outside of the screen area. I decided switch out the light bulb as it was near the end-of-life accouring to the number of hours it had been...
The buttons in this x0xb0x had been worn out over the years. I replaced them with Omron B3W-4050 buttons. These buttons are a bit pricey (compared to No Name chinese ones) but they are sealed so dust and grime will not get into the buttons. Apparently the dirt is the main reason for the buttons...
