DIY Adaptor/Multiple Panel for scope and DMM connections

This is an adaptor panel I put together in an hour or two to help with testing and setting up the CV Tools Modules. 

I used one of my 8HP DIY panels and  DIY kit 3 for the 3.5mm jacks. 

It is essentially an adaptor and multiple to allow easy connection to the scope via BNC connectors and to a DMM (digital multimeter) via the 4mm sockets. 

The top 3.5mm jack and BNC socket are connected together, the next jack down and BNC are similarly connected; i.e. a pair of 3.5mm jack to BNC adaptors. The lower pair of 3.5mm jacks. 1/4" jack, BNC and red 4mm socket are all connected together and the black 4mm socket is connected to 0V.

This is really useful for DIY applications too and very easy to make. I think an adaptor or multiple panel would make a great first DIY project.


I can also make these to order if anyone wants one (or something similar) but it is unlikely to become a standard product as all you really need is a pre-drilled front-panel and a few connectors.

Here it is (bottom right) in use in my CV Tools test rig routing the scope, DMM and sig gen to the module under test

New generic front panels for DIY kits

I now have stock of a range of 4HP and 8HP front panels to suit the Synovatron DIY Prototyping Kits. These can be purchased with the kits as an option or separately. 

The 8HP panel suits DIY Kit 1 and has two variants, one to suit a column of jacks (8.2mm holes) and a column of pots (7.5mm holes). The other variant has 3mm pilot holes to give you the flexibility to mix and match front panel components by drilling out to suit jacks, pots or switches, or left as is for 3mm LEDs.

The 4HP panel suits DIY Kit 3 and also has two variants, one to suit jack sockets (8.2mm holes) and the other with just 3mm pilot holes so they can easily be modified to larger diameters for jacks or switches or left as is for LEDs.

The panels are made from 2mm aluminium and have a brushed, clear anodised finish.  The mounting holes (slots) are suitable for both Doepfer and Analogue Systems hole pitches.

These panels make the kits more complete and I will also offer a set of knobs in DIY Kit 1 to finish it off.

Kit 1 options: The soft-touch knobs can be ordered in white, grey, red, orange, yellow, green or blue.

Prices range from £5.99 to £8.99 if ordered separately, a bit cheaper if ordered with a kit. The knobs are £1.25 for 5 if ordered with a kit.

The panels will also include a set of M3x6 screws and plain washers.

Update:

Here's a 8HP pilot hole panel that I drilled out for a customer so he could mount a mult on the left and an OSC303 on the right (Note: he bought the OSC303 as a kit without front panel and jacks. There's no point in trying to do this if you have one DinSyncs's excellent clear blue panels). The jacks were drilled out to 8mm, the pot to 7.5mm and the switch to 6mm. Looks pretty sexy!

Tone's top tips:  

(1) Cover the panel in masking tape so the swarf doesn't scratch the front finish. 

(2) start with smaller drill sizes and work up to the final size else you may end up with odd shaped holes.

(3) Deburr holes on both sides with a countersink bit.
