Roland TR-808 – Cleaning Instrument Switches
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.
Roland TR-808 – Noisy Snare, Clap and Toms
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...
Building the Yocto #24 – Adding a power switch
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...
x0xb0x – Repairing Bank Selector Encoder
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.
Building the Yocto #23 – Modding metal case
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...
x0xb0x – Replacing Potentiometers
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...
Benq w1060 Projector – Changing Bulb and Light Path Cleaning
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...
x0xb0x – Replacing buttons with Omron B3W-4050
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...
Building the Yocto #22 – Soldering the IO Board
I finished the IO board and connected it to the main board and it powered up! Unfortunately the sequencer buttons did not work properly so I could not initalize the EEPROM memory, more about that in a later post. Video and images after the click!
Building the Yocto #21 – Soldering the Sequencer
The sequencer is now fully assembled apart from the MCU and SPI EEPROM not being mounted, according to the instructions. Video and photos in the post!
