Modular synthesizer enthusiasts looking to learn how to build a VCO from scratch will appreciate the erica synths EDU DIY VCO, an analog voltage-controlled Oscillator (VCO) module in Eurorack format with separate sawtooth and pulse-wave outputs. The VCO operates in the 1V/oct range and includes coarse and fine-tune controls as well as pulse width modulation (PWM) with CV control and frequency modulation (FM) with CV control.

This VCO module is part of a DIY educational series that's designed to not only build a synthesizer from scratch but delves into the design and how components are chosen. The included 59-page manual takes you through the circuit-design process step-by-step, explaining every choice that was made and how it impacts the finished module. The kit includes the circuit board, electronic components, and mounting hardware. If you've ever wanted to learn how to build a synthesizer but were intimidated by the process, these educational DIY kits are your perfect solution.

Q: 1. Does this monitor accept power from a power bank using USB-C ?

A: The USB-C port of the Hollyland Mars M1 Enhanced 5.5" Wireless Transceiver Monitor is only for firmaware updates and not power unfortunately We offer USB-C dummy batteries that you could work with that would allow you to use a battery bank for powering the Mars M1.

Q: 2. I have the HLD-9 Battery Holder attached to my EM1 Mark II. Does this bracket still work with that accessory on the camera?

A: No - it does not. The RRS bracket is meant to be mounted directly under the camera body!

Q: 3. How does this not impede the full action of the LCD?

A: There have been no reports of the action on the LCD being impeded with the use of this RRS Modular L-Plate Set for Sony A7 IV, particularly since this product is still very new.

Q: 4. Is there an L-bracket compatible with the manfrotto 290 dual tripod? If not, is there a plate that can be used with this L-bracket and the manfrotto tripod? Thank you!

A: The Manfrotto 290-dual uses Manfrotto's 200PL proprietary plate and there currently isn't an L-bracket designed to work with them. You are able to attach a 200PL to the bottom of the L-bracket but not the L-component. In both cases, this defeats the purposes of the RRS L-bracket set for the Olympus OM-D E-M1 Mk II/III.

Q: 5. What bitrate is the signal transmitted at 1080p 60, I know the Pyro 7 is up to 12mbps as stated on its product page. But it is not stated for this Mars M1 Enhanced.

A: The Hollyland Mars M1 Enhanced 5.5" Wireless Transceiver Monitor has a bitrate of 12Mbps .

Q: 6. Will this fit the new A7R V?

A: No, the Really Right Stuff Modular L-Plate Set for Sony Alpha a1 is specific for the A1 and does not fit onto the A7R V.

Q: 7. how long does it take for this monitor to boot up?

A: The Hollyland Mars M1 Enhanced 5.5" Wireless Transceiver Monitor boots in less than 20 seconds.

Q: 8. is this compatible with Sony A7RV?

A: No, as of now Really Right Stuff hasn't confirmed this as of yet, but I do not believe that L plate will be fully compatible with the a7R V because this camera has a different 4-axis multi-angle LCD screen that swings out to the side; the L plate may prevent full use of the screen's movements. Also, the a7R V has a slightly different port configuration on the side now that there is a full-size HDMI port, so access to these ports may be limited with the a7R IV plate's design.

Q: 9. Does this bracket work with the OM SYSTEM OM-1 Mirrorless Camera?

A: No, the Really Right Stuff L-Plate Set for Olympus OM-D E-M1 Mark II and Mark III is not compatible for use with the OM SYSTEM OM-1 Mirrorless Camera.

Q: 10. How well does this fit the Mk III?

A: This bracket will fit well with the EM-1 MK3.
