Marchand Electronics manufactures and sells hand built and custom designed audio equipment. Phil Marchand produces active, passive, solid state and tube crossovers, power amps for audio or laboratory usage, tube and solid state pre-amps, bass eq, discrete op amps, and many more items.
It’s worth noting he has three free
software tools for the audio enthusiast. The coolest is simple component calculator for capacitor and resistor values for a variety of crossover models with crossover frequency and slope variables. I know this can probably be accomplished easily in excel these days but I’m personally a fan of dedicated tools that do one thing well.
There are very few dedicated DIY electronic music/synth cookbooks/reference books available out there so when ever I come across some I try to snatch them up. you can get all six of these spiral bound books from Thomas Henry for under $90 which cover some very specific topics for DIY synthesis and electronic music.
- An Analog Synthesizer for the 21st Century – $20.00
- The Electronic Drum Cookbook – $15.00
- Making Music with the 3080 OTA – $13.00
- Making Music with the 566 – $13.00
- Making Music with the NE570 Compander – $13.00
- The Noise Generator Cookbook – $13.00

I’m warming up to these hand made, custom order ‘stereos’ dubbed “Boom Cases”. Get it? Suitcase + Bass = ‘Boom Case’. I’ve posted a couple of my favorites along with a couple of the more preposterous vanity shots. Seriously though I can’t figure out if I love these or hate them. As long as I never see these in the hands of roaming gangs of suburban youth in malls across america I think I love them. From the website:
The BoomCase is a Self Powered, Portable Suitcase Stereo system that works with your iPod/iPhone or any device with a headphone jack. The BoomCase will last 10+ hours on a single charge (Charger Included). In addition to running on batteries, The BoomCase can also be plugged in when the party goes inside. To save on weight, you can opt for a plug-in only version.
In the WTF category…
An excellent thread detailing a build of the ‘Workshop Oscillator Machine’ (WOM) via Bugbrand. The WOM is a tone generator/oscillator designed around an NXP Hex Inverter and an NXP Hex Schmitt Trigger. What i particularly like about this kit is that it’s designed with the intent of usage in workshop and educational events and includes all required parts. Although i have not personally built this kit, I suspect by looking at it that it’s a nice balance between ease of build and functionality. And if you were so inclined Bugbrand includes the schematic on their site so you could always wire one up on your own, sans pcb, and see what happens.
This is the first time I’m posting on a product. But a monophonic bass synth based on the Atmel ATXMega32D4 microcontroller a for only $29 bucks is a pretty good deal if you ask me. What I really like though is the inclusion of a full schematic, something of a rarity these days in consumer electronic products. Available via MikroElektonika.
From the manual:
BassBoy is a monophonic digital MIDI controlled bass synthesizer. Device receives all information via MIDI input (connector).Sampling frequency is 31.25KHz which generates audio range up to 15.625Khz. Although it’s based on 8-bit processor, the signal processing inside the unit is 16-bit. The unit consists of oscillator which generates SAW & SQUARE WAVE using 16-bit band-limited wavetables, thus making the number of harmonics limited. After that, the signal itself goes through a simple implementation of MOOG filter, whose frequency range is chosen by MIDI commands and which is affected by the level of the envelope. The filtered signal then comes to the controlled amplifier, which creates the signal shape, and in the end through DAC (WM8762) and pre-amp circuit goes to the audio jack 6.35mm. The unit is mono, and 6.35mm jack is also used as carrier for the circuit board itself.
