Amazing ass… for a robot Yep, Japan still has the creepy robotics market cornered. Case in point is this robotic posterior. Don’t worry, they’ve included a dissection so you can see how the insides work too. [via Gizmodo] Time-lapse camera module results As promised, [Quinn Dunki] sent in a link to the photo album from [...]

[Quinn Dunki] just reported in on the latest iteration in her computer project which is called Veronica. This time she added RAM to increase the VGA performance of her build. Like just about every other part of the project, [Quinn] knew what she wanted to do, but had to overcome a lot of issues along [...]

It’s not really conceived as a spy cam, but it could be. [Quinn Dunki] built this tiny time-lapse camera project with racing in mind. She’s involved in a group that endurance races clunkers, and part of the fun is sharing the experience of riding around in the old beaters. The module seen above takes a [...]

[Quinn Dunki's] homebrew computer project is moving up another evolutionary rung. She needs a more versatile user interface and this starts with the data output. Up to this point a set of 7-segment digits has served as a way to display register values. But her current work is aimed at adding VGA output to the [...]

We’ve enjoyed seeing the development progress of Veronica, [Quinn Dunki's] 8-bit computer project. It started out on a breadboard, then moved to edge-connected PCBs, and now [Quinn] has given Veronica a body of her own. The donor is a Philco Model 42-327T and was produced in 1942. It was chosen because it is non-functional and [...]

When we hear about etching PCBs at home we assume that either Ferric Chloride or Cupric Chloride were used to eat away unmasked copper from the boards. But [Quinn Dunki] just wrote up her PCB etching guide and she doesn’t use either of those. Instead, she combines vinegar, hydrogen peroxide, and salt. It’s easier to find vinegar than muriatic [...]

[Quinn Dunki] got some free stuff from Element14 to evaluate, including this Mircrochip WiFi module. It’s been used as the centerpiece of an Arduino shield in the past, and she grabbed a copy of that library to see if it would play nicely with an ATtiny chip. What follows is a struggle to de-Arduino the [...]

Behold this ATtiny85 based EEPROM programmer. It seems like a roundabout way of doing things, but [Quinn Dunki] wanted to build to her specifications using tools she had on hand. What she came up with is an ATtinyISP USB programmer, pushing data to an ATtiny85, which then programs an EEPROM chip with said data. The [...]

[Quinn Dunki] has been busy through the holidays giving her 6502 processor-based computer a place to live. The most recent part of the project (which she calls Veronica) involved designing and etching a mainboard for the device. In the picture above it’s the vertical board which is right at home in the backplane [Quinn] also [...]

[Quinn Dunki] keeps rolling with her 6502 based computer build. This time around she’s added some memory to store the programs, but needed a way to get that code into the device. Above is her solution, a bank of hex switches used to program the 8-bit command and 16-bit address for each line of machine [...]

When it came time to try out some old-school computing [Quinn Dunki] grabbed a 6502 processor and got to work. For those that are unfamiliar, this is the first chip that was both powerful, affordable, and available to the hobby computing market back in the 1970′s. They were used in Apple computers, Commodore 64, and [...]

[Quinn Dunki] is looking to augment the tools she has available at her electronics bench and built the HEX Out as a mock-logic sniffer. The device reads 8 or 16-bit inputs, showing the current state of those connections on a 7-segment display. This requires that you’re comfortable reading Hex codes, but if you’re not it’s [...]

We often look at battery-operated hardware and shake our heads at the wastefulness of throwing away disposable batteries. There are some devices that minimize the waste, like those TV remotes that seem to never need new cells. But the C cells that [Quinn Dunki] kept replacing in her elliptical trainer were only lasting about three months at [...]

When designing a circuit on the bench, sometimes things work far better than they do in real life. [Quinn Dunki] learned this lesson over the last few months as she struggled with one of her recent creations, the Dish-o-Tron 6000. We featured the Dish-o-Tron back in April, and at that point things seemed to be [...]

[Quinn Dunki] got tired of messing around with wires when connecting things to her benchtop power supply, so she built herself useful little power bridge that plugs directly into any standard breadboard. The board is small and simple, but quite useful all the same. It was built to power both sides of the breadboard, and [...]

After having his mints disappear for quite some time [Quinn Dunki] came up with an idea to get back a the fresh-breath thieves. A bit of circuit design, parts scavenging, and free-form construction led to the creation of his mint-tin burglar system. Here’s how it works. Flip the on/off switch in the base of the [...]
