=== Specifications ===
See synthesizers.com:[httphttps://wwwweb.archive.org/web/20100104235751/http://synthesizers.com/technical.html#panels Panels]
=== Blank panels ===
The panels are made using 1.5mm (0.062") aluminium, which is thinner than that used for [[MOTM DIY parts#Blank panels|MOTM front panels]]. They're strengthened by the sides being bent over to form flanges. To mount them into the rack, the face of the panel is extended at the top and bottom by 0.4".<ref name="dotcom">[httphttps://wwwweb.archive.org/web/20100104235751/http://synthesizers.com/technical.html Technical Information], Synthesizers.com</ref>

== Panel parts ==
Avoid cheap parts, especially if mechanical. Invest in quality, you always get what you pay for. Otherwise your entire system might later develop intermittent faults.<ref>MuffMod Wiggler forum:[httphttps://www.muffwigglermodwiggler.com/forum/viewtopic.php?p=861269 On cheap parts...]</ref>
=== Knobs ===
Dotcom ([http://www.synthesizers.com/ Synthesizers.com]) use fluted dual-dot 1" Moog-style/[[Cosmo Corporation knobs]], available at:
* [http://www.smallbearelec.com/servlet/Detail?no=739 Small Bear]
* [https://web.archive.org/web/20110716181608/http://www.synthesizers.com/cabinets.html#parts Synthesizers.com]
For pointer knobs, Dotcom use {{fracsfrac|1|1|8}}" Moog-style/Cosmo Corporation skirted pointer knobs, available at:
* [http://www.smallbearelec.com/servlet/Detail?no=1109 Small Bear]
* [https://web.archive.org/web/20110716181608/http://www.synthesizers.com/cabinets.html#parts Synthesizers.com]
=== Potentiometers ===
Synthesizers.com use Alpha single-gang 24&nbsp;mm pots, available at:
* Mouser 100K linear [http://uk.mouser.com/Search/Refine.aspx?Keyword=31VA501-F 31VA501-F] and 100K log [http://uk.mouser.com/Search/Refine.aspx?Keyword=31VJ501-F 31VJ501-F]

* [https://web.archive.org/web/20110716181608/http://www.synthesizers.com/cabinets.html#parts Synthesizers.com] 100K, 1M
=== Switches ===
..., available at:
* [https://web.archive.org/web/20110716181608/http://www.synthesizers.com/cabinets.html#parts Synthesizers.com] DPDT, SPDT
=== Pushbuttons ===
..., available at:
* [https://web.archive.org/web/20110716181608/http://www.synthesizers.com/cabinets.html#parts Synthesizers.com]
=== Jacks ===
Dotcom modules use enclosed mono [[Switchcraft]]-style jacks, available at:
* [http://www.smallbearelec.com/servlet/Detail?no=90 Small Bear Electronics]
* [https://web.archive.org/web/20110716181608/http://www.synthesizers.com/cabinets.html#parts Synthesizers.com]
Switched {{fracsfrac|4}}" jacks are especially handy for [[normalising]] jack connections.
=== LEDs ===
...
Panel components sold by Synthesizers.com come with 6" wires and [[MTA Connector]] connector.
=== PCB Mounting ===
Synthesizers.com and some independent manufacturers mount the PCB parallel to the panel with [[standoff]]s, others mount PCBs perpendicular MOTM-style. [[PCB mounting bracket|4-40 steel mounting brackets]] are fine for this and also work with [[CGS]] boards.
 
PCBs can be mounted parallel using 1" (Mouser: 534-8405) and {{fracsfrac|1|1|4}}" (Mouser: 534-8407) threaded standoff posts. Black oxide screws, like the ones used by Synthesizers.com, are used to affix the standoffs to the front panel. Specifically, 4-40 steel {{fracsfrac|3|8}}" black oxide phillips pan head screws,<ref name="gf">Guitar Fool:[http://guitarfool.com/modules/hardware.html Hardware]</ref> are available from [http://www.aaronsmachinescrews.com/cfusion/DisplayProduct.cfm?ITEM=1701SN1368 Aaron's Machine Screws].
 
For perpendicular mounting with [[stooge brackets]] affixed by the pots or jacks, available at:
* [http://bridechamber.com/Brackets.html Bridechamber]
* [https://web.archive.org/web/20180228193533/http://synthcube.com/cart/index.php?route=product/search&filter_name=bracket%2Fsearch Synthcube]
Threaded right-angle brackets (Mouser: 534-621) can be mounted to the panel, using the 4-40 steel {{fracsfrac|3|8}}" black oxide phillips pan head screws.<ref name="gf" />
 
== Internal connectors ==
Line 66:
Dotcom uses MTA-100 connectors, using 24 awg wire. To fit the wires to the connectors, use the AMP MTA key style maintenance tool: AMP 59803-1 (DigiKey: A9982-ND).
=== Module power ===
Power supplies are connected using 6 way keyed MTA-100 connectors.<ref>http[https://wwwweb.archive.org/web/20100104235751/http://synthesizers.com/technical.html#internaldc Internal DC Module Power – 6 pin MTA]</ref><ref name="mw1739">Muff's Modules & More:[httphttps://www.muffwigglermodwiggler.com/forum/viewtopic.php?t=1739 Power distribution – updated], Mod Wiggler forum, Sep 2008</ref>
