SUPER-MOD GLITCH CAMERAS
For the past year, I have been building and selling these "Super-Mod" glitch cameras, and I thought it was about time I posted some details on the process of building them, as well as sharing some information on how they work for the numerous people who have purchased them from me so far. Thanks for waiting! 2X 'SUPER-MOD' The 2x 'Super-Mod' has two separate glitch channels with four controls.…
FISHERS (project pt.8)
-ASSEMBLING PARTS/FINISH: The faceplates I use are made from 3mm colored acrylic sheets that I buy from a local plastics store in Portland, Tap Plastics . It is a pretty cool store, and they sell scrap acrylic pieces by the pound, which is awesome! Sometimes I find unique colors in the scrap pile, but usually I just have custom sheets cut to order so that I have a variety of colors to choose from…
FISHERS (project pt.7)
-WIRING/DEBUGGING: Black and red wire for power connections With all of the circuit boards aligned to their temporary faceplates, and fitting to the enclosure how they should, the next step is wiring everything up and turning the power on for the first time, which is always exciting. The wiring process was pretty simple since I took the extra time to label everything well, and even had a sort of…
FISHERS (project pt.6)
-PREPARING THE ENCLOSURE: Prepping the keyboard enclosure is a lot of busy work, and gets very messy from all of the plastic chips, dust, and sometimes smoke. It is always a good Idea to clean up the work area first, and have my HEPA vacuum and smoke absorber at the ready. Wearing eye and respiratory protection is essential, too. It is really not fun to try and pick little plastic bits out of…
FISHERS (project pt.5)
-ASSEMBLING CIRCUIT BOARDS: Circuit board day–my favorite day! For some reason, waiting for my circuit boards to arrive from JLC PCB always makes me super anxious. I know that they will arrive on time, and be perfectly made to my specifications, but for those 5-10 days between ordering and them arriving, I can't help but feel like something terrible is going to happen, and won't get them because I…
FISHERS (project pt.4)
-DESIGNING CIRCUITS: Designing the circuit boards is by far my favorite part of any project. I am still using an old version of KiCad 5 that I have really had no reason to upgrade for the last few years. I have created my own custom footprint libraries for all of the parts I use, and the last time I upgraded KiCad it was a disaster, so I'm happy to stick with the old version. I'm sure I am missing…
FISHERS (project pt.3)
-PLANNING THE INTERFACE: The first step in designing the faceplates and arranging the hardware layout, is taking careful measurements of the keyboard enclosure, and drawing it up in my design software. It is important that the working perimeters of the drawing are as close to accurate as possible, so that I know the added hardware will all fit properly. For more than 10 years now, I have been…
FISHERS (project pt.2)
-PLANNING/BREADBOARD STAGE: VOICING I was hopeful that the circuit would be a good candidate for circuit bending, since there are so many big chips, and lots of analog circuitry. Unfortunately, there was really just not much that I could find that was useful. I tried bypassing the data lines to the ROM chip to try and get some kind of access to the piano voice sample using all manner of…
FISHERS (project pt.1)
1989 FISHER PRICE 3810 "REAL-SOUNDS PIANO" The Fisher Price 3810 Piano was a common toy during the early 90's. They were well made, and are still available in good condition on ebay, and sometimes can be found at thrift stores. The keyboard measures around 23 inches long, 8 inches wide, and about 2 inches thick. There are 32 keys that are slightly larger than standard mini-keys of the era. Despite…
TRIP DELUXE
The TRIP DELUXE is the second prototype of the TANDY TRIP rhythm/drone machine. This version has all of the same functionality as the first TRIP, but has 8 additional rhythms that can be selected with the touch-control inputs when the added 'RHYTHMS' switch is set to the 'ALT' position. While the 'RHYTHMS' switch is in the 'HOLD' position, the last ALT-RHYTHM selected will be held, and the…
TRIP
The TRIP project is the second part of the RadioShack Musical Elephant Keyboard(see PAL ). The TRIP is an experimental drum machine made from a dual-voice drum chip. The drum chip has 8 pre-programmed rhythms. Only the sound chip was used for this mod. The rest of the circuit and enclosure are built from scratch. FEATURES -Global Pitch modulation -8 preprogrammed rhythms with start/stop, and…
PAL
The PAL project started in early February of 2025, and was finished by mid April. The synthesizer is built around a monophonic keyboard voice chip from a RadioShack "Musical Elephant Keyboard" from the early 90's. Only the sound chip and the keyboard keys were used. The rest of the circuit and enclosure were designed and built from scratch. FEATURES -Two octaves of micro-keys -Voice…
CREATOY TRAINS
I found these two on Ebay in early November of 2024. They are somewhat generic looking train keyboards by the brand Creatoy from 1995. Many toys made by Creatoy from this era, and similar toys like them have a special place for me. As a child of the late eighties and early nineties, I would see a lot of these lesser known toys at friends' houses, and school growing up. At the time, it seemed like…
PT100
The Noystoise PT100 is an experimental synthesizer designed and built around the HD61702xx sound chip. The chip can be found in many Casio keyboards from the mid-to-late eighties, including the Casio PT100, hence the name. Beyond the HD61702xx chip itself, the rest of the synthesizer design is completely original. HD61702xx FEATURES: The chip has 12 selectable "Vowel-Consonant-Synthesis" voices;…
YAMAHA HS 200 REVISITED
In fall of 2024, the owner of the modified Yamaha HS200 I modified some 10 years ago contacted me to have the keyboard fixed. It was still mostly working, but the pitch range was not able to go up to standard tuning. It was unstable and wouldn't stay in tune. We mutually agreed that it would be best to send it back to me for a repair despite the cost and risk associated with shipping overseas…
NTDD
The NTDD is a PT2399 based dual-delay(DD) processor, and analog Dub-Siren circuit. DELAY: There are two PT2399 delay chips in series with independent delay time controls on the X and Y axis of the "TIME" joystick(Left). The delay-mix and feedback-amount are controlled together by the "ECHO" knob. The "REGEN X2" switch enables the output from delay-chip 1 to be fed back to its input, as well as to…
SUZUKI PK-37
Shortly after finishing the NTSH and NT05, I decided to start this project. I was looking for something to do that I could just slowly chip away at over the summer. I had been doing some reverse-engineering of some of my toy keyboards for fun. I started with a Casio MT-40, then moved on to the Casio SK-1 using Kicad to draw the schematics cleanly. After those, I needed a bigger challenge. I had…

GLITCH CAMERAS AND HOW
Circuit bending digital cameras has been a love of mine over the past decade or so. I recently picked up a new camera at the thrift store, and it reminded me that I really need to do a write up on it. In the mid 2000's, about the same time I started circuit bending my first Casio SK-1, I was really obsessed with this key chain camera I had. It had extremely low resolution and frame rate, and no…
NT05
The NT05 is a "LoFi RhythmBox" It consists of; -Two voices; "Sine" and "Noise" -Two 128 step pattern banks -Eight selectable rhythms -Two "Pad" envelopes -One LFO VOICES The Sine voice has a VCA knob, Distortion knob, and Pitch knob. The Distortion knob effects the waveshape of the oscillator. At the low end, the waveshape is triangular. Midway it is Sine, and at full, the oscillator is…
NTSH
The NTSH is a mini joystick noise synth. It consists of; - one white noise generator -one square wave oscillator -one 12db resonant LP filter -one Sample&Hold/envelope generator The controls; The joystick on the left controls the Filter Cutoff and the Pitch of the Square Wave VCO, while the joystick on the right controls the Gate frequency of the Sample&Hold, and the frequency of the Triangle Wave…
MATATRON!!!
My old buddy Matt Wright contacted me recently and asked if he could buy my FUNKY GLITCH BUDDY . I don't know why, but it is hard for me to sell things to good friends... Do you give them a discount?.. Or just give it away?.. Either way, I didn't want to give up my funky buddy just yet, so instead, I would build him something unique as a friendly gift. Matt is a master guitar tech/luthier, so I…
EHX 16 SECOND DELAY MOD
A friend of a friend contacted me in the summer of 2020 to have his EHX 16 Second Delay reissue modified. I had done some pedal mods for him in the past, so I was willing to give it a go, even though I was pretty bogged down with remodeling projects in my house. I was happy to be in my shop again and working with something other than drywall.. I didn't end up finishing the mod until the winter of…
FUNKY GLITCH BUDDY-REVISED
While cleaning shop, I came across an old friend. I built this little keyboard monster back in 2013. The FUNKY GLITCH BUDDY was an interesting concept, but it suffered from some pretty challenging design flaws that I had always wanted to fix, but never had the time. For one, the keyboard would draw so much current due to the fact that the keys were all infrared proximity sensors. There were a lot…
