At last years Defcon conference in Las Vegas, NV, hardware hackers Joe Grand, Mark ‘Smtty’ Smith, LosT, RenderMan and FirmWarez discussed their experiences in using various microcontrollers. Interesting stuff, particularly If you’re just getting started with electronics and are trying … Read more
KF5OBS writes: Quick overview of the Tektronix MDO4104B-6. Also showing how to properly calibrate the passive probes and debunking the myth that license modules enable theft of options.
In this presentation from DEFCON 21, Adam “Major Malfunction” Laurie and Zac Franken of Aperture Labs go hardcore with chip analysis. For some time it has been possible to discover the inner workings of microprocessors with the help of a … Read more
SpriteMods has published their design for a DIY NAND flash reader. When security-testing the ‘secure’ USB-sticks I got my hands on in the past, I needed a way to directly read the NAND-flash these sticks use to store the data … Read more
How often have you been caught without the right cables? You can salvage an old ugly one from somewhere, or make a last minute part order that delays your project. Never again! The Premium Make Your Own Keyed Cable Kit … Read more
Today the Premium Make Your Own Cable Kit is available at Seeed Studio. During development we ended up with tons of connectors, so we kitted them up into a sample pack. 200 cable kit sample packs are now available in the … Read more

At Hacker Camp Shenzhen we learned to reball BGA chips at a mobile phone repair school. This technique was developed to repair cell phones with little to no equipment. That means no expensive reballing rigs, no collection of tiny replacement … Read more
Chuck of LinearLogiX writes: We bought the TM240A and found it works pretty good for our needs. A couple items I found was that using the SMD type tant caps on a reel, I had to actually Grind the side to open width … Read more
Cypress Semiconductor, makers of the popular PSOC4 Pioneer kit, are making their PSOC4 chips available for a limited time for $1.00 each, including free worldwide priority shipping. (Note, this price is for the chip alone, NOT the Pioneer Kit.) “PSoC4 … Read more

Here’s another better way to store your electronics components by Nick of Arachnidlabs: I think I’ve found a better way to store those parts, though. I sourced some 3” x 5” antistatic bags for a pittance, lasercut a box to hold them in, … Read more
Peter Lawrence has been working on using a PIC as a CMSIS-DAP ARM debugger. I wanted to see what was feasible in the way of a very-low-cost ARM board. OK, that doesn’t sound original, but stick with me. The solutions … Read more
Professionally printed shrink tubes arrived for the Bus Pirate probe cable prototype we discussed yesterday. 110 each of 10 labels cost 180RMB ($30). These are about about 5x more expensive than printing them ourselves on the L-Mark (ribbon+tube cost). The … Read more
In reply for our earlier post about printing heat shrink cable labels, TomKeddie posted a picture of this Xilinx cable in the forum: Just for reference, this is what Xilinx does. I guess the real question is when are you looking … Read more
63 resistor reels just arrived for a test 0603 OOMP part book. Books and sheets should be here tomorrow. We’ll stuff some samples and get an idea of the time involved this weekend if everything goes smoothly.
What’s the best way to store your electronics components? Systemstech shared us his parts storage for all his components: This is what I use and I haven’t had any troubles with it and static. Via the forum.
Ray writes, “When your project needs a real-time clock (RTC), don’t you hate that the popular DS1307 costs several dollars? I recently came across Microchip’s MCP7940N, which is an inexpensive alternative to DS1307. On the hardware side it is pretty … Read more
