The Business Card Synthesizer is a tiny synth that can be connected to a Business Card Sequencer, other synth gear, or played by itself.These fun little kits were introduced at Knobcon 2018 as a build workshop. Now you can get your very own.Headphones can be connected directly to the output of the synth, and there are plenty of knobs to play with, so you can easily make noises anywhere. Great for learning about synthesizers!We send you a board and a bag of parts so you can build it yourself. Difficulty level = medium (it’s all through-hole, but some of the soldering is kind of small). The kit includes the PCB, preprogrammed microcontroller and all required parts to build kit.Features:Pulse, square, triangle, and sawtooth wavesGlide2 LFOs with pulse, square, saw, triangle and ramp shapesAttack / DecayLow-pass filterSample and HoldManual gate trigger (can be locked on)Course and fine-tune controlsControls:S&H Button: Enables Sample & Hold, which disables the external CV IN jack and uses LFO1 and LFO2 to determine oscillator pitch. LFO1 sets the sample rate (SHAPE is ignored for this), and LFO2 is the wave that gets sampled.GATE Button: Manually turns on the gate so sound comes out of the synth. This control is momentary, but you can latch it on by tapping the S&H button while holding the GATE button down.COARSE TUNE: Adjusts the pitch of the oscillator up or down in large incrementsFINE TUNE: Adjusts the pitch of the oscillator up or down in fine incrementsSHAPE: Changes the shape of the wave produced by the main oscillator (VCO). Turning this control fully CW gives you a triangle wave. Start turning it CCW takes you through sawtooth/ramp, then at about the 12:00 position you get a square wave. Conti Review: Great! - High quality kit, fast shipping, and was fun to build! Plenty of interesting sounds to be found... Review: Easy build. Fun to play with - Definitely fun to play with. The operating instructions don’t help at all unless you are pretty familiar with synths and sequencers already. Easy build though. A few smaller solder spots but nothing tough. Works as it should. Have used it on a bunch of different equipment ## Features - A tiny synth that can be connected to a Business Card Sequencer, other synth gear, or played by itself - Pulse, square, triangle, and sawtooth waves - 2 LFOs with pulse, square, saw, triangle and ramp shapes - Attack / Decay, Sample and Hold, Glide, Low-pass filter - Can be powered by 7-15V power supply (not included) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RM7XVC7 | | Best Sellers Rank | #74,365 in Musical Instruments ( See Top 100 in Musical Instruments ) #83 in Tabletop Synthesizers | | Body Material | Fiberglass | | Brand | Division 6 | | Brand Name | Division 6 | | Color | Blue | | Connector Type | 2.5mm jack | | Customer Reviews | 4.3 out of 5 stars 21 Reviews | | Included Components | case | | Manufacturer | Division 6 | | Material | Fiberglass | | Model Name | Business Card Synthesizer | | Model Number | 738676134667 | | Part Number | BSYNKIT | | UPC | 738676134667 | ## Product Details - **Color:** Blue - **Brand:** Division 6 - **Material:** Fiberglass - **Model Name:** Business Card Synthesizer - **Included Components:** case ## Images ![Division 6 Business Card Synthesizer DIY Kit - Image 1](https://m.media-amazon.com/images/I/61GbqncbZEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great! *by J***S on August 4, 2019* High quality kit, fast shipping, and was fun to build! Plenty of interesting sounds to be found... ### ⭐⭐⭐⭐ Easy build. Fun to play with *by A***. on March 26, 2025* Definitely fun to play with. The operating instructions don’t help at all unless you are pretty familiar with synths and sequencers already. Easy build though. A few smaller solder spots but nothing tough. Works as it should. Have used it on a bunch of different equipment ### ⭐⭐⭐ Nice project for an advanced beginner or above *by N***R on July 10, 2020* This is a fun little project and the result is a nice little synthesizer that can work with the matching business card sequencer. The instructions were very clear and assembly went quickly. There were no real challenges, but I recommend that new builders do a couple of soldering practice kits first. I’d also recommend that you use a decent temperature-controlled soldering station with low temperature rosin core solder. I typically use super-thin 63/37 soldier and use heat sinks when soldering semiconductors and I’ve had good results. One negative is the lack of response of division six’s “support“ department. My first business card synth was dead when I completed the build. No lights, nothing. I’d asked them for a schematic or test points I could use to determine the cause of the issue. I know that we’re all suffering the “Covid Craziness”, but it’s been quite a while and it’s been complete crickets from their end. The second one I built worked fine with no issues. If I ever hear back from their “support” people, I plan to resurrect the dead synth and give it to one of my kids. ## Frequently Bought Together - Division 6 Business Card Synthesizer DIY Kit - Division 6 Business Card Sequencer V2 Kit - 4093 Chaos NAND Handheld DIY Kit - LoFi Drone Oscillator Synth --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/154415450-division-6-business-card-synthesizer-diy-kit](https://www.desertcart.us/products/154415450-division-6-business-card-synthesizer-diy-kit) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-10*
