![]() ![]() As it turns out, common makeup techniques can help you do just that. You might want to dodge this without arousing suspicion, just for a little privacy now and then. Cloud servers churn through every picture uploaded to social media, phone cameras help put faces to names, and CCTV systems are being used to trace citizens in their day-to-day lives. Interested in more about the chips behind this build? We’ve talked about the 555 and how it came to be, taken a look inside the 741, and gotten a lesson in LM386 loyalty.Ĭontinue reading “Classic Chip Line-Up Powers This Fun Dub Siren Synth” → Posted in Musical Hacks Tagged 555, 741, dub, echo, lm386, oscillator, reverb, siren, synthįacial recognition is everywhere these days. I built-in speaker and a nice-looking wood enclosure complete the build, which honestly sounds better than any 555-based synth has a right to. Five pots on the main PCB control the effects, while a second commercial reverb module - modified to support echo effects too - adds depth and presence. The video below starts with a demo, and it’s hard to believe that the diversity of sounds this box produces comes from just a pair of 555s coupled by a 741 buffer. The ear-splitting versions were eventually replaced with sampled or synthesized siren effects for recording studio and DJ use, which leads us to the current project. As explains, dub sirens started out as actual sirens from police cars and the like that were used as part of musical performances. That’s exactly the complement of chips that powers this fun little dub siren. Add in other silicon stalwarts like the 741 op-amp and the LM386 audio amp, and you’ve got a Hall of Fame lineup for almost any project. Chief among these is the ubiquitous 555 timer chip, which nearly 50 years after its release still finds its way into the strangest places. There’s a certain elite set of chips that fall into the “cold, dead hands” category, and they tend to be parts that have proven their worth over decades, not years. Posted in Toy Hacks Tagged electric jeep, jeep toy, motor controler If you’re hungry for more, this isn’t the first such story we’ve covered. But it seems to be a load of fun, and we can’t help admitting we’d like a go in it. The result is not quite Mad Max as while it’s faster than the original there’s still something of the pedestrian about it. AYITI THE COST OF LIFE HACKED UPGRADEOtherwise it received an upgrade and stiffening of its chassis and steering components, and the kids plastic steering wheel was replaced with a wooden one. All its electronics were dead, so rather than do a complete motor upgrade he instead doubled the voltage and installed decent motor controllers with an Arduino sending them instructions. ![]() This one is a two-motor model and unexpectedly comes with a steering motor for parental remote control. These toys usually have one or two 12V high-speed motors driving plastic gear trains for the rear wheels. When your friends are off to the post-apocalyptic Wasteland Festival and present you with a defunct Power Wheels clone toy Jeep to make ready for the festivities, what are you to do? If you happen to be, soup it up with new electrics and uprated steering, and send it forth into the hideous no-mans land. Last time we checked in with, they had built this solar-powered ball-flinging delight.Ĭontinue reading “Tiny BEAM Robot Smiles Big At The Sun” → Posted in Robots Hacks, Solar Hacks Tagged beam, beam robotics, capacitor, solar powered robot, voltage monitor We love to see people work at all different scales. Be sure to watch it toddle around in the demo video after the break. They will even make the bot move indoors! If you want to build one of these, you can’t beat ’s guide. started in a great place when they found these 25% efficient monocrystalline solar panels. This here is an example of a photovore or photopopper - it moves toward light using simple logic by charging up a capacitor and employing a voltage monitor to decide when there’s enough to run two tiny vibration motors that make up its legs and feet. This was before the large, flat storage capacitor came and covered everything up. Here’s a bunch of tutorials to get you started. What are BEAM robots, you say? Technically it stands for Biology Electronics Aesthetics and Mechanics, but basically the idea is to mimic the movement of bugs, usually with found components, and often with solar power. What have you been working on during the Great Chip Shortage? has been living up to their handle and building BEAM robots that are smaller than any we’ve seen before. ![]()
