All through-hole version of the Logic Shrimp
jarin made an all through-hole version of the Logic Shrimp logic analyzer: I’ve made variation of Logic Shrimp, using only through-hope components found in my junk box. More details and pictures can be found here. There is no schematics drawn, I built it just using datasheets and original schematics – and I’m too lazy to […]
Bus Pirate PIC programmer free PCB build
SineWave built an early version of the Bus Pirate PIC programming adapter. This version would have needed several cables, we made the final design stackable instead. The Bus Pirate PIC programmer project is has been idle for a while. It would be nice if the Bus Pirate could do absolutely everything, but it’s a ton […]

Superprobe free PCB build
Rubi built a free Superprobe PCB. RN1, RN2, and RN3 are 0603 resistor array 4-packs, but Rubi didn’t have any. Instead, individual 0402 resistors are hand-soldered in their place. Nice work!

CPLD breakout free PCB build and some suggestions
Tanukifu built a free CPLD breakout board. I had a few suggestions if there is a future version in planning – maybe useful, maybe not – I thought about posting them on the site but I haven’t followed the discussions long enough to have a good feel for how to say things there and I […]
Flat cable to header converter adapters
MickM built flat cable to header converter adapters : I was using some character LCD displays and realised that the cables were impossible to plug into the displays that I actually had. My PCB was single row of 16, the LCD was 2×7, no backlight. So I made an adapter for it. Via the forum.
Class D amplifier assembled
NBitWonder built a class-D amplifier Class-D amplifier is a highly efficient amplifier that operates its output devices as switches instead of as variable resistors. We posted a highly experimental version of this project last November, and it met with a surprising amount of positive feedback from the DIY community. Therefore, we developed it as a […]

DIY inkjet printer
This quarter at the University of Washington a group of students (Patrick Hannan, Jared Knutzen, Joy Markham, & Myself – Nicholas C Lewis) produced some documentation on the development of a DIY inkjet printer. This project is attracting a lot of attention and spawning some interesting ideas. There are people talking about adapting it to […]

Bus Blaster v2.1 (v2.6) free PCB build
Tanukifu successfully built a free Bus Blaster v2.1 PCB. It was uneventful build, except for a few bridges on the PCB. Be sure to inspect the Bus Blaster board if you’re building a free PCB. There have been a lot of bridge issues, we probably messed up the fill or gerber settings. v2.1 is actually […]

Shooting arcade game using CPLD
Here’s a video of Jeri Ellsworth’s latest project for element14, a shooting arcade game using the MachXO2 CPLD. During the design phase, she drew inspiration from various sources, including the dynamic logic found in UK horse racing betting sites, which helped her fine-tune the game’s real-time responsiveness. The game is simple in principle: use an […]
