What is Sector101?
Sector101 is a spare-time hobby project. My name is Brian Allan and I am based in the United Kingdom.
The products on this site are designed, assembled and tested by myself. For this I use an ESD complient PCB workstation, soldering tools, magnifiers, test equipment, and synthesizers
to test the products.
These projects have been inspired by members of the forums at YamahaForums.co.uk
where I am user Shadowmask.
This forum is well worth a visit as there is a collective goldmine of information about current and past Yamaha synth products. There is a huge following of the older models like the DX Series, SY & TG, and the EX Series. The forum list can be viewed here
What is your day job?
My regular job is in the electronics industry where I have worked for over 27 years. In that time I've gained knowledge
of the automated SMD (Surface Mount Device) assembly line process and PTH (Plated Thru-Hole) assembly process.
In recent years I have been involved with Test & Test Development. In layman's terms
this means designing a test for a product, testing the product, and debug the product if it fails the test. The products I deal with
are many and varied: High-end audio equipment, oil refinery monitoring equipment, web-based security systems, fiber-optic optical switching controllers.
A useful skill I've picked up along the way is PCB rework / repair & modification. This is where components on the PCB are to
be carefully removed and replaced, repairing broken tracks and lands, or circuit modifications where tracks are intentionally cut
and mod-wires routed between components. Any of these jobs can involve replacing simple thru-hole components, or the more
taxing high-density surface mount FPGA and DSP devices with 100's of fine legs, or BGA devices with 200+ Ball Pads.
How did this all these Sector101 projects start?
It all started in 2006 with an idea I had about making some type of memory circuit that would work in place of the long-obsolete Yamaha SYEMB06 memory board for my SY85.
I had no schematic for the SYEMB06 so after a lot of probing on the SY's connectors and internal components I finally got a rough schematic worked out. With this info the first prototype veroboard-mounted circuit was built and working.
Around the same time there was a discussion on the YamahaForums site about re-creating the SYEMB06 module as
a proper PCB assembly.
As time went on
I got more info about the Yamaha SYEMB06 assembly from the forum members. After some PCB design, assembly and testing the first batch of 30 SYEMB06 clones were made.
After the SYEMB06 project came the MCD Sweet16 multi-bank card, the SYEMB05 for the SY99, and the EXFLM2 for the EX5/7/5R Series. More recently four more projects have emerged - the WaveBlade 8MB Programmable WaveCard for the SY/TG, the DataBlade16 multi-bank MCD card, the EXM-E3 128MB DRAM module for the Alesis Fusion & Akai MPC5000, and the SIIEX24 24 Voice Expansion for the Novation Supernova II and Nova II..
What other services can you offer..?
Experience in my regular job and with the Sector101 projects are given me abilities in these fields:
to component level.
- Removal & replacement of SMD & Thru-Hole components. Repair to mechanical damage.
- Single-sided PCB & Multi-Layer boards produced from schematic drawings.
- EPROM, PAL, GAL, PIC, Flash.
