A double and triple delta robot by Aad van der Geest: The double delta is a novel design that is lighter, safer and more energy efficient compared to other robotic arms. This is because all three of the actuators are placed at a stationary point in base of the arm. As a result, the arm […]

WORKSHOP VIDEO: Beers in Akiba’s Workshop
Akiba at FreakLabs brings wireless tech to the open hardware community. Recent geek credits include the Safecast radiation measurement project, and designing wireless EL wire controllers for Wrecking Crew Orchestra. You also saw him in our tour of Akihabara parts market last year. Recently he welcomed us into his Tokyo workshop for a tour and […]
ATX breakout board case prototype
Some quick shots of the atx case test fit number 2. Looks great. A few spacing tweaks and it goes to production.
FIRST DRAFT: Programmable dummy load
This is a programmable current sink, usually used to simulate different current loads for power supplies. We have always wanted to build one, but we’ve stalled several times. This design is based on the simple analog load posted by Bearmos. It’s not intended to be a final project, it’s just an experimental prototype to […]
NEW PROTOTYPE: Bus Pirate v4
Bus Pirate v3, and all previous Bus Pirates, are based on a chip with 64K of program space. Last year we stuffed so many features into the firmware that we used all the space. It was time for new hardware based on a new chip. We didn’t want to run out of space again soon, […]
Free PCB Sunday: Logic Shrimp logic analyzer
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week we’re giving away two […]
Week in (p)review: February 13, 2011
Don’t forget to share your current project in the comments or the forum. This week our favorite project gets a free SOIC protoboard. Here’s a summary of major developments over the last week: Jawi released a new version of his client for the Logic Sniffer. This supports new features in the experimental Verilog core from […]
Week in (p)review: February 06, 2011
Don’t forget to share your current project in the comments or the forum. This week our favorite project gets a free SOIC protoboard. Here’s a summary of major developments over the last week: We released a bunch of abandoned or stalled prototypes: XT IDE disk controller, Ethernet JTAG debugger, Ethernet LED driver, PIC Z-machine emulator, […]
Week in (p)review: January 30, 2011
Don’t forget to share your current project in the comments or the forum. This week our favorite project gets a free SOIC protoboard. Here’s a summary of major developments over the last week: The new forum is running, we hope you enjoy the added features of the phpBB software. It was a bit of a […]
Free PCB Sunday: Bus Pirate v3.0SE
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few professionally-made PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This odd-ball Bus Pirate is […]
Confessions of a prototyper: #twatch v1/v1b
Last week we released the #twatch v2, an ethernet backpack for 20×4 character LCDs. This wasn’t the only version of the #twatch that we designed. V2 is based on the slick, inexpensive, single-chip ethernet microcontroller, the PIC 18F67J60. The biggest downside to the 18f67J60 is that it can only be programmed an average of 100 […]
Bus Pirate v3 PCBs pass testing
Sign up to be notified of v3 preorders here. We plan to sell the Bus Pirate v3 for $30, shipped worldwide. Preorder discussion. This picture from our workbench shows the new Bus Pirate v3 (left) and the Bus Pirate v2go (right). The Bus Pirate V3 PCB arrived yesterday. We stuffed it last night, and it […]
